Abstract
Objective To develop consensus recommenda-tions on urine drug monitoring (UDM) in patientswith chronic pain who are prescribed opioids
Methods An interdisciplinary group of clinicianswith expertise in pain substance use disordersand primary care conducted virtual meetings to re-view relevant literature and existing guidelines andshare their clinical experience in UDM before reach-ing consensus recommendations
Results Definitive (eg chromatography-based)testing is recommended as most clinically appropri-ate for UDM because of its accuracy however institu-tional or payer policies may require initial use ofpresumptive testing (ie immunoassay) The rationalchoice of substances to analyze for UDM involvesconsiderations that are specific to each patient andrelated to illicit drug availability Appropriate opioidrisk stratification is based on patient history (espe-cially psychiatric conditions or history of opioid orsubstance use disorder) prescription drug monitor-ing program data results from validated risk assess-ment tools and previous UDM Urine drugmonitoring is suggested to be performed at baselinefor most patients prescribed opioids for chronic painand at least annually for those at low risk two ormore times per year for those at moderate risk andthree or more times per year for those at high riskAdditional UDM should be performed as needed onthe basis of clinical judgment
Conclusions Although evidence on the efficacy ofUDM in preventing opioid use disorder overdoseand diversion is limited UDM is recommended by
the panel as part of ongoing comprehensive riskmonitoring in patients prescribed opioids forchronic pain

Introduction
Key Issues Regarding Drug Monitoring for PatientsPrescribed Opioids for Chronic Pain
Rationale for Drug Monitoring
Opioid analgesics are prescribed for up to one-third ofpatients with chronic pain treated in primary care clinics[1] but may be associated with unintended consequen-ces of misuse opioid use disorder overdose and diver-sion Morbidity and mortality presumably due torespiratory depression increase with concomitant useof opioids and other central nervous system depres-sants (eg benzodiazepines nonbenzodiazepine sleepmedications muscle relaxants tricyclic antidepressantsand alcohol) [2ndash5] Prescription opioid use has report-edly decreased from 2010 to 2014 [6] and opioid-related deaths also decreased from 2010 to 2012 [7]However deaths from illicitly produced fentanyl andrelated compounds [8ndash12] and heroin [713] have in-creased across various time periods in the past decade
Patients often do not voluntarily report prescription drugmisuse or illicit substance use [1415] and some mayfeign symptoms to obtain opioids for diversion [16]which necessitates objective assessments such as drugmonitoring [17] Although opioid use is monitored pri-marily for patient and public safety drug monitoring hasimportant implications for compliance with regulatorymandates and standards for responsible opioid pre-scribing [18ndash22] Urine drug monitoring (UDM) has theadded benefit of improving patient adherence to opioidtherapy [2324] potentially leading to better patient out-comes and greater trust between provider and patient
Types of Drug Monitoring and Terminology
This consensus report focuses on UDM although druguse can be detected via multiple biological samples(eg oral fluid blood hair [25]) Use of nonurine matri-ces may prevent sample alteration and avoid privacyconcerns however urine testing has been widelyadopted in clinical practice for monitoring because ofadequate drug concentration in the urine accuracy ofdeveloped tests and clinically relevant detection win-dows (ie three to five days) [25ndash27]
In this consensus report the term urine drug monitoring(UDM) is used instead of urine drug screening urinetoxicology screening or urine drug testing The UDM

term conveys an ongoing process rather than a singletesting event and UDM has a nonpunitive patient-centric connotation as variations on the term drugtesting may be associated with punitive intent in lay lan-guage Diversion is used in this consensus report tomean a transfer (eg giving selling) of prescriptiondrugs for unlawful distribution or use [20] Misuse is de-fined as taking medications in a manner other than pre-scribed even when treating a medical condition [2028]Substance use disorders are a cluster of cognitive be-havioral and physiological symptoms indicating contin-ued use of a psychoactive substance (eg to getldquohighrdquo) despite negative consequences and harm[2930] Opioid use disorder is characterized by signsand symptoms of compulsive prolonged self-administration of opioids in doses exceeding a medicallyappropriate amount or for no legitimate medical purposedespite clinically and functionally significant impairmentssuch as health problems and failure to meet major so-cial responsibilities [30] Because the colloquial labelsldquodirtyrdquo and ldquocleanrdquo to describe UDM results can stigma-tize patients and reduce their likelihood of seeking andaccepting recommended help [31] ldquoinconsistent withtherapyrdquo ldquounexpected resultsrdquo ldquoconsistent withtherapyrdquo and ldquoexpected resultsrdquo are used in this report
Description of UDM Technologies
A presumptive UDM test is a screening immunoassaythat is relatively inexpensive can be used in the office atpoint of care (POC) and produces a rapid result (egwithin minutes) [28] Clinicians may be unfamiliar withthe characteristics of immunoassays which have vari-able sensitivity and specificity (eg 0ndash50 missedpositive results and 11ndash100 incorrectly identifiedpositive results across drug classes) [32] and maytherefore miss substances that can lead to inaccurateimmunoassay results (Figure 1) [33ndash40] The classicldquourine screen testsrdquo are often enzyme immunoassaysthat target amphetaminesmethamphetamines canna-bis cocaine phencyclidine and opioids (ie theldquofederal fiverdquo [41]) and are based on a specific antidrugantibody reaction [42] Opiate immunoassays can moreaccurately detect naturally occurring opiate alkaloids(ie morphine codeine) than commonly prescribed syn-thetic (eg fentanyl methadone) and semisynthetic(eg buprenorphine oxycodone oxymorphone hydro-morphone) opioids [42] Immunoassays are at bestsemiquantitative (ie an estimate of levels only) becauseof cross-reaction across multiple drugs [43] Reasonablysensitive options are now available for testing manycommon drug classes [43]
Definitive UDM can be used for initial or confirmatorytesting (ie to verify the results of a presumptive testthat are contested by the patient) and includes qualita-tive or quantitative gas chromatography (GC)ndashmassspectrometry (MS) liquid chromatography (LC)ndashMS andLCndashtandem MS (LC-MSMS) technologies [2844]
Definitive testing is often more specific and usually moresensitive than immunoassay for the substances testedbut it is also more costly [28] Although some immuno-assays can detect chemical adulterants (ie any sub-stance that lessens validity of testing) [45] definitivetesting is less susceptible to adulterants and decreasesthe likelihood of inaccurate or false results [28]Definitive testing accurately identifies metabolites to con-firm that the parent drug was indeed ingested [28] andcan also detect potentially abnormal opioid metabolism[46] Metabolite results may be confusing to clinicianswho are not aware that some prescribed opioids aremetabolites of others (eg oxymorphone is a metaboliteof oxycodone and hydromorphone is a metabolite ofhydrocodone [18])
UDM Challenges and Unmet Needs
Although the effectiveness of UDM as a risk mitigationtool or strategy against overdose opioid use disorderand diversion has been inadequately studied nationalguidelines from the last decade [18ndash2240] have recom-mended UDM as best practice in patients prescribedopioids for chronic pain These guidelines usually sug-gest initial immunoassay before (confirmatory) definitiveUDM because of cost concerns [182040]
Potential conflicts of interest (eg clinic owners finan-cially benefiting from frequent POC testing [47] andcommercial laboratories promoting the use of definitiveUDM beyond clinically appropriate thresholds) have ledpayers to increase scrutiny of UDM [4849] Current re-strictive payer policies can limit use of and reimburse-ment for UDM Reimbursement changes regularly andauthors recommend that clinicians refer to currentCenters for Medicare and Medicaid Services (CMS) re-imbursement policies (Table 1) [44] and commercial in-surance coverage benefits [50] as well as considervariations in costs across practice settings to stay up todate on changes Of note costs of appropriate UDMmay be offset by savings in overall health care (ie viaimprovement in care and reductions in drug misuseopioid use disorder and diversion) [51] but this relation-ship requires further study
Clinicians receive minimal education on UDM and oftenlack adequate knowledge of how to both choose an ap-propriate UDM test [52] and interpret complex results[53] Lack of understanding can lead to misinterpretationof UDM results failure to identify patterns of harmfuldrug use and inappropriate management of patientsClinicians may compromise patient care by denying ap-propriate treatment or discharging patients from theirpractice after inaccurately concluding that they are mis-using or diverting opioids owing to a false-positive orfalse-negative UDM result [5253]
With UDM as a current best practice and given its inher-ent complexities in clinical practice updated guidance isneeded The purpose of this consensus report is to pro-vide clinicians with a framework for practical and rational

[AAPM]) adjudicated any discrepancies to develop the fi-nal list of questions
1 Which UDM test(s) should be used and in whichpatients prescribed opioids for chronic pain shouldthe tests be used according to a medical literaturereview clinical experience clinical chemistry of drugtesting and practical considerations
2 How should patients undergoing UDM be stratifiedfor opioid misuse risk
3 How often should UDM occur in patients with lowmedium and high risk for opioid misuse or opioiduse disorder
For background the panel members identified existingguidelines that have been most influential in UDM inchronic pain practice Articles were obtained fromPubMed using the search terms urine drug testing andchronic pain Studies published from June 13 2012 (iethe date of the previous guidelines specific to UDM [40])to April 6 2016 (the date of the search) were includedSearch results were filtered to exclude narrative reviewscase reports studies involving nonurine matrices (egblood oral fluid hair) laboratory tests and any studieswith findings not relevant to the three selected questionson UDM Studies in patients with cancer pain were ex-cluded to narrow the patient population similar to otherguidelines [18ndash20] however this should not be construedas a recommendation to not perform UDM in patientsprescribed opioids for cancer-related chronic pain To ad-dress potential literature gaps additional references (egkey landmark studies) were identified through referencelists and by panelist recommendations
Using the process followed by the Centers for DiseaseControl and Prevention (CDC) Guideline for PrescribingOpioids for Chronic Pain [1854] an abbreviated Grading ofRecommendations Assessment Development andEvaluation (GRADE) methodology was performed Studieswere evaluated and graded as type 1 through 4 which gen-erally corresponded to the following study categories [54]
1 randomized controlled trials (RCTs) or observationalstudies with overwhelming evidence
2 RCTs with important limitations or observational stud-ies with exceptionally strong evidence
3 observational studies or RCTs with notable limitations
4 clinical experience and observations observationalstudies with important limitations or RCTs with sev-eral major limitations
Phase 2 Convening Expert Panel Members forInteractive Discussions and Voting to Reach Consensus
Consensus panel meetings for UDM occurred via web-based teleconferences on August 11 and 18 2016 for
a total of five hours Section leaders (JF JAG RCPand DPA selected by co-chairs to lead discussions)reviewed the literature and led interactive discussionsabout the main questions related to UDM before con-sensus on recommendations was reached with a modi-fied nominal group technique [5556] This consensusmethod was selected because of its demonstrated va-lidity long history of use and time efficiency as well asthe ability for all panelists to provide input [57] After ev-ery panelist provided an answer to a question panelistsvoted for their preferred answer if multiple options wereproposed Additional discussion cycles and voting wereperformed until consensus was reached
Phase 3 Preparation of the Consensus Report
The content of this report reflects an extensive review ofexisting UDM research and guidelines discussion fromseveral meetings and communications among the ex-pert panelists and consensus recommendationsPanelists reviewed and revised content in multiplestages of manuscript development before finalization
Results
Six recent guidelines that address UDM in patients withchronic pain were identified by panelists as most rele-vant to the three key questions The literature searchfound 85 studies pertaining to UDM 21 additional refer-ences were added to address gaps in the existing litera-ture on topics requested by panelists After filtering forrelevance to the three main questions (performed by aneditorial service directed by the authors) 41 referencesfrom the expanded literature search were included all ofwhich were graded for scientific merit as type 3 (lowquality) or 4 (lowest quality) by the authors Validationstudies even when well designed were not consideredequivalent to RCTs and were rated as lower quality
All graded references are included in the RelevantLiterature sections for each question Because of thelack of high-quality evidence addressing the priorityissues for this report recommendations were notassigned a strength category Recommendations(Figure 2) should be considered consensus opinionsbased on evolving evidence

assessing baseline opioid use and opioid misuse in al-most all patients with chronic pain being considered foropioids as well as for ongoing monitoring of patients re-ceiving opioids for chronic pain unless presumptivetesting is required by institutional or payer policies A ra-tional approach to choosing the most relevant analytes(ie substances to be tested) for UDM testing is pro-posed (in the Expert Panel Discussion section for ques-tion 1) and should be documented by the clinician
Existing Guidelines
In contrast to this expert panelrsquos recommendation pre-viously published guidelines suggest that patientsundergo presumptive testing with immunoassay whenthey are prescribed opioids for chronic pain[18202240] some guidelines specify that the testshould be POC [2040] Confirmatory definitive tests aregenerally reserved for resolving unexpected results fromimmunoassays [18202240] or for detecting specificopioids that cannot be identified with standard immu-noassays [18] According to the CDC [18] CMS [58]and other payer policies [5059] definitive testing is ap-propriate only when it affects clinical decision-makingand patient management The Washington State guide-lines suggest considering the following drugs for aUDM panel in addition to medications prescribed alco-hol amphetamines barbiturates benzodiazepinescannabinoids cocaine fentanyl methadone opiatesand oxycodone [22]
Relevant Literature
Surveys indicate that UDM in patients prescribedopioids for chronic pain varies widely (ie 19ndash636of patients receive UDM at some point during treatment[60ndash63] and 69ndash100 of clinicians administer UDM[295263ndash66]) which demonstrates a need for guid-ance Traditionally POC immunoassays have been usedfor initial screening in UDM because they provide rapidresults at relatively low cost [28] However false-positiveresults (eg 22 for opiate immunoassays [32]) can becaused by cross-reactivity [28] and false-negativeresults (eg 30 for opiate assays [32]) may occur be-cause of drug concentration cutoffs and cross-reactivityin particular among drugs in similar chemical classes[67] Some opioids and benzodiazepines are not welldetected by immunoassays [67]
Compared with immunoassays definitive testing candetect a greater number of compounds (eg variousbenzodiazepines [67ndash69]) and demonstrates higher sen-sitivity and specificity [70] The gold standard of defini-tive testing was considered to be GC-MS [71] but LC-MSMS has become a favored method [28] because itis associated with less drug interference and can beperformed with smaller urine volumes than for GC-MS[71] Validation of two new LC-MSMS methods wasidentified through our literature search [7273] As a ca-veat detection of metabolites of some prescriptionopioids (eg buprenorphine by certain routes ofadministration) or illicit substances (eg heroin) with

LC-MSMS is challenging in part because of insufficientsensitivity of tests and individual variation in drug metab-olism [7475]
Although (confirmatory) definitive testing is often used toverify unexpected immunoassay results recent evidencesuggests that it is more accurate than immunoassay atassessing patientsrsquo substance use at initial screening[76ndash78] A hybrid UDM approach in which each drugwas measured with either immunoassay or LC-MS(depending on which platform has better accuracy andspeed for each drug) reduced the need for confirmationtesting and time to results [79] In a study at a privatepain practice clinicians and patients discussed unex-pected results from initial immunoassay UDM and opennonjudgmental communication was emphasized thisapproach led to only 3 to 5 of cases requiring con-firmatory GC-MS testing [80] The clinical utility of a hy-brid immunoassayLC-MS approach and of effectivepatient communication to prevent the need for confir-matory GC-MS testing will need to be furtherestablished
Expert Panel Discussion
The panelists expressed concerns about limited sensitiv-ity and specificity as well as misinterpretation errors withclass-specific immunoassays especially in the primarycare setting The initial low cost of immunoassays maybe negated by their potential inaccuracy which can in-crease the downstream financial burden to confirm con-flicting or unexpected results and potentially increasecosts for additional treatments and office visits when apatient is inappropriately continued or discontinued fromopioids because of misinterpretation of results Definitivetesting although often more expensive than immunoas-say initially includes a more comprehensive panel ofsubstances and is more sensitive and specific fordetecting adherence to prescribed opioids and use ofother substances For these reasons several panelistsconsider definitive testing to be the most rational choicefor UDM and elect to use it exclusively for both prelimi-nary testing and follow-up testing when results are con-tested by the patient
The expert panel recognizes that not all clinicians havereliable access to definitive testing laboratories andsome payers reimburse for definitive testing only afteran immunoassay result is inconsistent with therapy Therecommendations in this consensus are intended to beconsidered together with practical clinical and payerconcerns When required by payers and institutionsimmunoassays may be sufficient for monitoring low-riskpatients particularly when clinicians and patients en-gage in open communication
Given the potentially high cost of definitive testing ratio-nal selection of analytes is recommended Appropriatesubstances to analyze for UDM include all controlled
substances (and selected noncontrolled coanalgesicssuch as antidepressants and anticonvulsants) that a pa-tient is prescribed as well as substances unexpectedlyfound at previous UDM Inclusion of additional medica-tions andor alcohol is driven by their potential for harm(ie risk-relevant testing) For identification of substan-ces most likely to be used and diverted consult recentnational survey results [81] and relevant geographic data[82] Greater numbers of analytes will likely need to betested for patients at higher risk for substance usedisorders
Complexities regarding UDM test properties necessitatethat clinicians have access to an expert (eg toxicolo-gist knowledgeable pain or addiction specialist pathol-ogist) when choosing the most appropriate test andinterpreting unexpected results Clinicians should alsobe aware of relevant state mandates regulations andguidelines [83] descriptions of UDM requirements bystate are available from state medical boards and theAAPM website (httpwwwpainmedorgadvocacystate-updates)
Question 2 How Should Patients Undergoing UDMBe Stratified for Opioid Misuse Risk
Expert Panel Recommendations
To guide UDM frequency assess and stratify patientswho are prescribed opioid therapy for chronic pain withthe following strategies
bull Perform a physical examination and obtain relevantpatient history for eventsdiagnoses and behaviorsthat have been shown to predict opioid misuse andopioid use disorder (eg history of substance use dis-orders psychiatric conditions sexual abuse) includinginformation from previous providers for patients trans-ferring care
bull Use validated tools to assess the risk for aberrantmedication-taking behavior opioid misuse opioid usedisorder and the potential for respiratory depressionoverdose
bull Check prescription drug monitoring programs(PDMPs) and previous UDM results when available
Existing Guidelines
Some guidelines [182022] recommend the use of riskassessment tools to stratify patients receiving opioidsthe Opioid Risk Tool (ORT) and Screener and OpioidAssessment for Patients with PainndashRevised (SOAPPVR -R)are frequently mentioned in other guidelines[18224084] Tools deemed most relevant by panelistson the basis of validation studies and use in practiceare described in Table 2 [18192284ndash94] There is aneed for further clinical validation of existing tools [19]and for development of newer and more accurate toolsthat incorporate additional risk factors [1895] Risk tools

are just one part of a comprehensive patient evaluation[2040]
Relevant Literature
Several tools for predicting and determining current risk ofaberrant medication-taking behaviors (eg lost prescrip-tion request for early refill) opioid misuse and opioid usedisorder are reported in the literature [96ndash99] In a painclinicndashbased study a semistructured clinical interview byan addiction psychologist was more sensitive than theORT Pain Medication Questionnaire and SOAPP-R atpredicting aberrant drug-related behavior [98] TheSOAPP-R showed the highest sensitivity of these self-report measures but may overestimate risk [98]
The use of external information (eg PDMPs) can alsoimprove patient management [100] In a university-based multidisciplinary pain management center misuseand diversion were detected more frequently by addingUDM andor a PDMP check to a baseline strategy ofcomparing patient reports and review of medicalrecords [101] However a systematic review of primarycare pain clinic and Veterans Administration (VA)Medical Center settings concluded that no single proce-dure or set of variables was sufficient to identify patientswith chronic pain who are at risk for opioid misuse orharmful substance use [97]
Expert Panel Discussion
The expert panelists suggest that patients be assessedfor risk of aberrant medication-taking behavior misuseand opioid use disorder to determine the frequency ofUDM A high-dose cutoff alone (eg 120-mg morphineequivalent dose per day [22]) was perceived as being in-adequate for identifying high-risk patients because highdoses may be appropriate to accommodate develop-ment of tolerance in specific patients [192187] In addi-tion patients predisposed to misuse may be at risk ofopioid use disorder or unsafe use even with low tomoderate doses
No specific risk assessment tool or behavioral assess-ment is recommended by panelists Clinicians are en-couraged to choose one or more of the many availabletools that match their preferences and can be incorpo-rated into their electronic medical records and workflow Understanding why specific factors predict risk ismore important than knowledge of the risk assessmenttools themselves (Figure 3 [1997102ndash107]) Risk strati-fication is not static and regular reevaluation of patientcircumstances (eg loss of a job divorce) is recom-mended An unexpected UDM result increases apatientrsquos risk of misuse and opioid use disorder neces-sitates more frequent testing and prompts reconsidera-tion of whether to modify opioid therapy or refer thepatient to a pain or addiction specialist
A comprehensive evaluation to assess the presence orrisk of misuse and opioid use disorder includes ques-tions about patientsrsquo history of substance use disordersand current clinical characteristics (eg from a physicalexamination) input from patientsrsquo family members andother health care providers (eg psychiatrists previouspain specialists) and pill counts Behaviors that may in-dicate increased likelihood of misuse or opioid use dis-order include requests for early refills [108]unauthorized dose escalations [109] and use of anotherindividualrsquos medication [109] Substance use disorder isgenerally associated with one or more of the four ldquoCsrdquo(ie impaired Control over use Compulsive useContinued use despite harm and Craving) [110]
A few simple questions (eg single-item screeningquestions [SISQs] for alcohol and drug use [93111]) fol-lowed by a discussion with patients is an efficient wayfor clinicians to incorporate risk assessment into theirpractice Reviewing a patientrsquos history of controlled sub-stance prescriptions in the PDMP is another method forassessing potential opioid misuse or substance use dis-order Clinicians should be aware of their statersquos regula-tions recommendations and resources regardingPDMPs [112] All states have or are planning to imple-ment a PDMP but reporting times vary and not everyprovider is required to participate in PDMPs in all states[112ndash114] The Comprehensive Addiction and RecoveryAct of 2016 is intended to improve the efficiency ofthese programs to track prescription drug use and helpprevent inappropriate use [115] Despite their inconsis-tencies PDMPs (when available) have become standardof care as part of patient risk evaluation WhetherPDMP data will predict aberrant behaviors or other ad-verse outcomes is not yet known and represents a gapin the science and an unmet need
Question 3 How Often Should UDM Occur in Patientswith Low Medium and High Risk for Opioid Misuseor Opioid Use Disorder
Expert Panel Recommendation
Perform UDM at baseline in patients prescribed opioidsfor chronic pain During ongoing monitoring performUDM at least annually for low-risk patients two or moretimes per year for moderate-risk patients and three ormore times per year for high-risk patients Additionalmonitoring can be performed at any risk level as fre-quently as necessary according to clinical judgment
Existing Guidelines
Recent guidelines recommend UDM at least annually forall patients regardless of risk [18] every six months totwo years for patients at low risk for opioid misuse oropioid use disorder [202240] one to three times peryear for moderate-risk patients [2022] and at least twoto four times per year for high-risk patients [202240]

The CDC Guideline for Prescribing Opioids for ChronicPain does not recommend tailoring the monitoringschedule according to risk because tools that predictharmful use lack sufficient accuracy [18] Several guide-lines [182122] suggest periodic UDM testing duringscheduled visits truly random testing outside of sched-uled clinic visits may not be feasible in many settings(eg primary care) or appropriate for all patients [18]
Relevant Literature
The identified studies related to UDM frequency do notdifferentiate strategies for low- moderate- and high-risklevels Nevertheless clinical trials assessing the effectsof UDM on outcomes are particularly relevant to deci-sions regarding frequency of monitoring (SupplementaryTable 1) Adherence to prescribed opioids is higher withmore frequent UDM according to a retrospective analy-sis of patients with chronic pain in private practices[116] In two prospective trials at an interventional painmanagement practice adherence monitoring that in-cluded random UDM was associated with reductions inindicators of opioid misuse (determined via periodicchart review UDM pill counts and verification of infor-mation with treating clinicians and pharmacies) [24] andillicit drug use (determined via UDM) [117] In anotherstudy a comprehensive risk reduction strategy includ-ing UDM led to decreased pill confiscations by law en-forcement agents and improved primary care providersrsquoperceptions of the overall quality of pain management[118] A structured program designed to support pri-mary care providers with chronic pain management ledto a greater-than-two-fold increase in UDM 22 months
after initiation of the program which was associatedwith a 727 relative decrease in total emergency de-partment (ED) visits and a 596 relative decrease inunscheduled primary care provider visits per patient onaverage [119]
The main negative clinical consequence of UDMreported in the literature was a lower likelihood ofpatients attending a second visit at an urban academicpain clinic after urine testing was used in the first officevisit [120] Individuals with positive test results for an il-licit substance were less likely to attend the second visitthan those with a negative result [120] Although thisstudy suggests that UDM at first visit may hinderpatient-clinician trust patient response to UDM mayvary by clinical setting by how the rationale for UDM isexplained to the patient and by the degree to whichUDM becomes routine in clinical practice
Many studies showed significant benefits of UDM how-ever a few did not No association between UDM and all-cause mortality was found in VA patients [121] althoughan association was not necessarily expected in this sam-ple of patients with a high burden of comorbiditiesAnother study conducted in a large health care systemshowed that an opioid risk reduction initiative (includingrecommendations on UDM) increased use of UDM with-out affecting rates of unexpected results (eg negative forprescribed opioids or positive for cannabis) [122]
Several studies and surveys of physicians (eg pain andaddiction specialists) nurses PAs and other health careprofessionals mainly from pain practices and academiccenters have assessed the frequency of UDM during

opioid therapy for chronic pain [296580123124]which provides context for recommendations on fre-quency Patients with chronic pain received an averageof 34 UDM tests per year according to a 2007 study ina Kentucky private pain practice [80] The frequency ofUDM testing increased by an average of 34 yearlyfrom 2005 to 2008 in a clinical laboratory serving a largeacademic center [123] Surveys indicated that individualpain and addiction experts differed in their frequency ofUDM use from testing at every office visit to yearly[2965] although most preferred random testing[65124] As a caveat these surveys did not focus onprimary care settings
Expert Panel Discussion
The expert panel did not specify how the relative riskcategories should be determined aside from suggestingseveral potential risk assessment tools and strategies(see the Question 2 section) Baseline UDM testing is tobe performed either before initiation of opioid therapyor for those continuing opioid therapy from another pro-vider within three months of the first office visit If thepatient received UDM testing from another providerwithin the previous year and the results were consistentwith prescribed opioid therapy no immediate retestingmay be needed to continue therapy
Regular UDM is recommended even in low-risk patientsbecause their circumstancesbehaviors can change overthe course of therapy Patients at especially low risk(eg receiving low-dose as-needed opioids) mayrequire infrequent UDM (eg every two years) Moderate-risk patients may become higher or lower risk dependingon their environment and stressors intense monitoring isusually not required in these patients but periodic reevalu-ation of their situationsrisk factors is appropriate
High-risk patients require more frequent individualizedUDM testing than those at low or moderate risk al-though the evidence supporting the effectiveness of in-tense monitoring is weak Most primary care providerscan best care for high-risk patients by referring them toa pain and addiction specialist when available Primarycare clinicians who are trained in chronic pain manage-ment utilize UDM are experienced in interpreting UDMresults and have access to consultant toxicologists maybe able to appropriately care for high-risk patientsandor comanage them with a pain specialist Currentguidelines for UDM in patients with substance usedisorder recommend use of personalized testingregimens [28]
Additional Expert Panel Recommendations andDiscussion
UDM Rationale
Clinicians are encouraged to include information relatedto UDM in patient-provider agreements and explain to
patients that the primary goals of UDM are to improvethe safety and effectiveness of therapy by monitoringadherence Furthermore UDM is strongly recommendedas part of a universal precautions approach [125]Consistent UDM results provide objective data to sup-port decision-making during chronic opioid therapy
UDM Process
The panelists recommend that clinicians discuss theUDM process openly with patients as they do with allother clinical testing and document the time of lastmedication use before urine collection Unexpectedresults may be caused by laboratory errors (eg mislab-eling) or by sample adulteration including substitution ofsynthetic or another individualrsquos urine Signs of tamper-ing include temperature outside the normal range of90 F to 100 F within four minutes of sample collectionpH outside the normal range of 45 to 80 low creati-nine concentration (ie 20 mgdL) low specific gravity(ie 1003) presence of adulterants or detection ofparent drug without metabolites [28] Variation in metab-olite levels may also result from pharmacogenetic anom-alies or drug-drug interactions affecting drugmetabolism [28126]
Strategies to prevent sample tampering depend on theclinical setting and can include observed collection(viewed as overly invasive of a patientrsquos privacy) achain-of-custody protocol (ie documentation for han-dling of the specimen) and a truly random collection(ie a protocol to notify the patients of required testingwithin a set period) [28] Although observed urine sam-ple collection at pain clinics has been recommended[83] this practice and chain-of-custody protocols aretypically not followed Despite risk-mitigation strategiesdedicated individuals can still manipulate their UDMsamples or consume prescribed medication before of-fice visits to conceal misuse or diversion Patients withan opioid use disorder may not be able to control theirdrug use to avoid unexpected UDM results despitescheduled collection
Alcohol Screening
For patients with a substance use disorder alcohol maybe problematic and prohibited in any amount for otherpatients with chronic pain only high-risk alcohol use(eg binge drinking) is a concern Many opioids includeblack box warnings about the concurrent use of alcoholbecause of the potential for fatal overdose [127] Onereviewed guideline recommends screening for alcoholwith UDM in patients with chronic pain [22] ethyl glucu-ronide ethyl sulfate or ethanol in UDM indicates alcoholuse [128] As a caveat immunoassay and definitiveUDM may not differentiate between alcoholic beveragesand alcohol-containing medications mouthwashes andhand sanitizers [28] Instead of UDM the panelists
Argoff et al

recommend the SISQ ldquoHow many times in the past yearhave you had (five or more drinks [men] four or moredrinks [women]) in a dayrdquo from the National Institute onAlcohol Abuse and Alcoholism [111] to identify un-healthy alcohol use as this question is simple to admin-ister and is validated [129] In primary care settings thesensitivity of the alcohol SISQ for identifying alcohol usedisorder is 88 and the specificity is 84 [130]
Cannabis Screening
Practices for cannabis screening vary [131] individualprescribers can decide whether detecting cannabis byUDM is appropriate by consulting local laws [132133]and common practice as well as by considering theadvantagesdisadvantages discussed below At the timeof this publication cannabis is federally illegal (ie clas-sified by the US Drug Enforcement Administration asSchedule 1 under the Controlled Substances Act) butseveral states have passed legislation to decriminalize itfor medical andor recreational use [131ndash134] The CDCGuideline for Prescribing Opioids for Chronic Pain indi-cates that the clinical implications of a positive UDM re-sult for cannabis are uncertain [18] the VAUSDepartment of Defense guidelines estimate the length oftime it can be detected in urine [21] and theWashington State guidelines suggest implementing anoffice policy for patients who use cannabis [22] Theseguidelines [182122] and this consensus report do notprovide formal graded recommendations for or againstUDM screening for cannabis or for interpretation of theresults
Clinicians who avoid cannabis testing may miss criticalinformation that could inform patient monitoring and im-prove safety Data from Colorado indicate increased EDvisits hospitalizations and proportions of fatal motor ve-hicle accidents related to cannabis intoxication after de-criminalization [134ndash136] Illegal use of cannabis is amarker for opioid misuse and substance use disorders[137] and a rationale to classify a patient as high riskAnother concern is that patients may divert prescriptionopioids to purchase cannabis
If clinicians choose to assess patientsrsquo nonprescriptioncannabinoid use there is a validated SISQ for drugs in-cluding cannabis (ie ldquoHow many times in the past yearhave you used an illegal drug or used a prescriptionmedication for nonmedical reasonsrdquo) [93] with a sensi-tivity of 97 and a specificity of 79 for substance usedisorders in primary care settings [130] Although somemetabolites of synthetic cannabinoids (eg spice) canbe analyzed with specialized immunoassayschromatographyspectrometry-based assays are betterfor assessing the many emerging synthetic cannabi-noids and their metabolites [138]
A subject of ongoing debate is whether co-administration of opioids and cannabis (used
recreationally or medically) is safe or reasonable for clini-cians to allow Cannabis is increasingly accepted formedical purposes especially for cancer pain syn-dromes However allowing patients with chronic pain touse cannabis is a potential liability for clinicians (includ-ing pharmacists) regardless of the drugrsquos legal status intheir state [139] The safety of cannabis for patients withchronic pain is not clearly established [140] and little isknown regarding the safety of concurrent use withopioids apart from the potential opioid-sparing effects ofcannabis [141] The composition and dose of the manyactive components in cannabis vary widely [133142]which leads to variable toxicity [143] and complicatessafety studies Cannabinoids may inhibit cytochromeP450 2D6 [144] (involved in opioid metabolism [145])and therefore affect both the efficacy of opioids and theability to detect metabolites in UDM The panelists pro-posed that a single clinician be responsible for manag-ing both opioid and cannabis use in states where thedrug has been decriminalized and the benefits of con-current use outweigh the risks
Interpreting UDM Results and Implications forChanging Clinical Practice
The panelists believe that clinicians should follow manu-facturer instructions for specific POC UDM tests and di-rect any questions about interpreting results to anexpert in toxicology or clinical pathology Laboratoriesperforming UDM have a responsibility to provide cleartest results answer questions and offer support on clin-ical decisions When clinicians are confronted with un-expected results potential causes for false-positive andfalse-negative results (eg quinolone antibiotics tolme-tin Figure 1) are important to investigate A summary ofcommunications and discussions about results with thelaboratory and other experts can be included in themedical record to document the medical necessity oftesting and related clinical decision-making
Communications with patients about the purpose andresults of UDM should be nonjudgmental and nonpuni-tive and should focus on safety and risks associatedwith misuse and opioid use disorder To avoid unex-pected results open discussion with patients is recom-mended and may include asking questions such as ldquoIfwe test you today what will we find in your urine Willthere be any surprisesrdquo Development of a plan to ad-dress UDM results that are inconsistent with therapy issuggested to mitigate safety risks for patients and po-tential regulatory board sanctions for clinicians Of noteUDM results that are consistent with prescribed opioidscannot differentiate among appropriate use occasionaluse or misuse and opioid use disorder negative UDMresults for prescribed opioids cannot distinguishbetween infrequent need for medicine overuse and run-ning out falsification of the urine sample and diversionResults of UDM are only part of the clinical information

(eg including patient history) that must be consideredbefore a treatment plan is changed
Detailed recommendations on proper opioid prescribingand appropriate changes to patient care after unex-pected UDM results are outside the scope of this con-sensus report but are discussed in other guidelines[18202240] In brief options to address unexpectedUDM results include open and nonjudgmental discus-sions with patients additional confirmation testing in-creased monitoring a switch to a nonopioid painmedication or referral for treatment of an opioid usedisorder [18202240]
Three studies from the Philadelphia VA Medical Center in-vestigated how UDM results affected provider behavior[119146147] additional research to determine how UDMresults should influence patientsrsquo therapy is warranted Inthe absence of this information a follow-up consensusmeeting to evaluate expert opinion was suggested
Conclusions
In summary the expert panel made the following rec-ommendations regarding UDM (Figure 2)
1 Use definitive UDM testing (eg with GC-MS LC-MS or LC-MSMS) as the most clinically appropriatemethod for assessing baseline opioid use and opioidmisuse in most patients with chronic pain being con-sidered for opioids as well as for ongoing monitoringof patients receiving opioids for chronic pain unlesspresumptive testing is required by institutional orpayer policies A rational approach to choosing themost relevant analytes for UDM testing is proposedand should be documented by the clinician
2 To guide UDM frequency assess and stratify patientsprescribed opioid therapy for chronic pain with thefollowing strategies
bull perform a physical examination and obtain relevantpatient history for eventsdiagnoses and behaviorsthat have been shown to predict opioid misuseand opioid use disorder (eg history of substanceuse disorders psychiatric conditions sexual abuse)including information from previous providers forpatients transferring care
bull use validated tools to assess risk for aberrantmedication-taking behavior opioid misuse opioiduse disorder and the potential for respiratory de-pressionoverdose
bull check PDMPs and previous UDM results whenavailable
3 Perform UDM at baseline in patients receiving opioidsfor chronic pain During ongoing monitoring performUDM at least annually for low-risk patients two ormore times per year for moderate-risk patients andthree or more times per year for high-risk patientsAdditional monitoring can be performed as frequently
as necessary according to clinical judgment (egworrisome patient behavior related to the prescribedmedication)
The recommendations in this consensus report are meantto provide practical advice on implementing rational UDMacross a broad range of clinical practices in a patient-centric manner Some clinicians may not have access toappropriate resources to perform routine definitive UDMor to refer patients to pain specialists alternatives are pro-vided in the expert panel discussion sections Higher-quality studies on patient outcomes with UDM areneeded As a next step a consensus recommendationinitiative similar to this one that discusses appropriate clini-cian actions in response to test results that are inconsis-tent with prescribed therapy is warranted

Abstract
Objective To develop consensus recommenda-tions on urine drug monitoring (UDM) in patientswith chronic pain who are prescribed opioids
Methods An interdisciplinary group of clinicianswith expertise in pain substance use disordersand primary care conducted virtual meetings to re-view relevant literature and existing guidelines andshare their clinical experience in UDM before reach-ing consensus recommendations
Results Definitive (eg chromatography-based)testing is recommended as most clinically appropri-ate for UDM because of its accuracy however institu-tional or payer policies may require initial use ofpresumptive testing (ie immunoassay) The rationalchoice of substances to analyze for UDM involvesconsiderations that are specific to each patient andrelated to illicit drug availability Appropriate opioidrisk stratification is based on patient history (espe-cially psychiatric conditions or history of opioid orsubstance use disorder) prescription drug monitor-ing program data results from validated risk assess-ment tools and previous UDM Urine drugmonitoring is suggested to be performed at baselinefor most patients prescribed opioids for chronic painand at least annually for those at low risk two ormore times per year for those at moderate risk andthree or more times per year for those at high riskAdditional UDM should be performed as needed onthe basis of clinical judgment
Conclusions Although evidence on the efficacy ofUDM in preventing opioid use disorder overdoseand diversion is limited UDM is recommended by
the panel as part of ongoing comprehensive riskmonitoring in patients prescribed opioids forchronic pain

Introduction
Key Issues Regarding Drug Monitoring for PatientsPrescribed Opioids for Chronic Pain
Rationale for Drug Monitoring
Opioid analgesics are prescribed for up to one-third ofpatients with chronic pain treated in primary care clinics[1] but may be associated with unintended consequen-ces of misuse opioid use disorder overdose and diver-sion Morbidity and mortality presumably due torespiratory depression increase with concomitant useof opioids and other central nervous system depres-sants (eg benzodiazepines nonbenzodiazepine sleepmedications muscle relaxants tricyclic antidepressantsand alcohol) [2ndash5] Prescription opioid use has report-edly decreased from 2010 to 2014 [6] and opioid-related deaths also decreased from 2010 to 2012 [7]However deaths from illicitly produced fentanyl andrelated compounds [8ndash12] and heroin [713] have in-creased across various time periods in the past decade
Patients often do not voluntarily report prescription drugmisuse or illicit substance use [1415] and some mayfeign symptoms to obtain opioids for diversion [16]which necessitates objective assessments such as drugmonitoring [17] Although opioid use is monitored pri-marily for patient and public safety drug monitoring hasimportant implications for compliance with regulatorymandates and standards for responsible opioid pre-scribing [18ndash22] Urine drug monitoring (UDM) has theadded benefit of improving patient adherence to opioidtherapy [2324] potentially leading to better patient out-comes and greater trust between provider and patient
Types of Drug Monitoring and Terminology
This consensus report focuses on UDM although druguse can be detected via multiple biological samples(eg oral fluid blood hair [25]) Use of nonurine matri-ces may prevent sample alteration and avoid privacyconcerns however urine testing has been widelyadopted in clinical practice for monitoring because ofadequate drug concentration in the urine accuracy ofdeveloped tests and clinically relevant detection win-dows (ie three to five days) [25ndash27]
In this consensus report the term urine drug monitoring(UDM) is used instead of urine drug screening urinetoxicology screening or urine drug testing The UDM

term conveys an ongoing process rather than a singletesting event and UDM has a nonpunitive patient-centric connotation as variations on the term drugtesting may be associated with punitive intent in lay lan-guage Diversion is used in this consensus report tomean a transfer (eg giving selling) of prescriptiondrugs for unlawful distribution or use [20] Misuse is de-fined as taking medications in a manner other than pre-scribed even when treating a medical condition [2028]Substance use disorders are a cluster of cognitive be-havioral and physiological symptoms indicating contin-ued use of a psychoactive substance (eg to getldquohighrdquo) despite negative consequences and harm[2930] Opioid use disorder is characterized by signsand symptoms of compulsive prolonged self-administration of opioids in doses exceeding a medicallyappropriate amount or for no legitimate medical purposedespite clinically and functionally significant impairmentssuch as health problems and failure to meet major so-cial responsibilities [30] Because the colloquial labelsldquodirtyrdquo and ldquocleanrdquo to describe UDM results can stigma-tize patients and reduce their likelihood of seeking andaccepting recommended help [31] ldquoinconsistent withtherapyrdquo ldquounexpected resultsrdquo ldquoconsistent withtherapyrdquo and ldquoexpected resultsrdquo are used in this report
Description of UDM Technologies
A presumptive UDM test is a screening immunoassaythat is relatively inexpensive can be used in the office atpoint of care (POC) and produces a rapid result (egwithin minutes) [28] Clinicians may be unfamiliar withthe characteristics of immunoassays which have vari-able sensitivity and specificity (eg 0ndash50 missedpositive results and 11ndash100 incorrectly identifiedpositive results across drug classes) [32] and maytherefore miss substances that can lead to inaccurateimmunoassay results (Figure 1) [33ndash40] The classicldquourine screen testsrdquo are often enzyme immunoassaysthat target amphetaminesmethamphetamines canna-bis cocaine phencyclidine and opioids (ie theldquofederal fiverdquo [41]) and are based on a specific antidrugantibody reaction [42] Opiate immunoassays can moreaccurately detect naturally occurring opiate alkaloids(ie morphine codeine) than commonly prescribed syn-thetic (eg fentanyl methadone) and semisynthetic(eg buprenorphine oxycodone oxymorphone hydro-morphone) opioids [42] Immunoassays are at bestsemiquantitative (ie an estimate of levels only) becauseof cross-reaction across multiple drugs [43] Reasonablysensitive options are now available for testing manycommon drug classes [43]
Definitive UDM can be used for initial or confirmatorytesting (ie to verify the results of a presumptive testthat are contested by the patient) and includes qualita-tive or quantitative gas chromatography (GC)ndashmassspectrometry (MS) liquid chromatography (LC)ndashMS andLCndashtandem MS (LC-MSMS) technologies [2844]
Definitive testing is often more specific and usually moresensitive than immunoassay for the substances testedbut it is also more costly [28] Although some immuno-assays can detect chemical adulterants (ie any sub-stance that lessens validity of testing) [45] definitivetesting is less susceptible to adulterants and decreasesthe likelihood of inaccurate or false results [28]Definitive testing accurately identifies metabolites to con-firm that the parent drug was indeed ingested [28] andcan also detect potentially abnormal opioid metabolism[46] Metabolite results may be confusing to clinicianswho are not aware that some prescribed opioids aremetabolites of others (eg oxymorphone is a metaboliteof oxycodone and hydromorphone is a metabolite ofhydrocodone [18])
UDM Challenges and Unmet Needs
Although the effectiveness of UDM as a risk mitigationtool or strategy against overdose opioid use disorderand diversion has been inadequately studied nationalguidelines from the last decade [18ndash2240] have recom-mended UDM as best practice in patients prescribedopioids for chronic pain These guidelines usually sug-gest initial immunoassay before (confirmatory) definitiveUDM because of cost concerns [182040]
Potential conflicts of interest (eg clinic owners finan-cially benefiting from frequent POC testing [47] andcommercial laboratories promoting the use of definitiveUDM beyond clinically appropriate thresholds) have ledpayers to increase scrutiny of UDM [4849] Current re-strictive payer policies can limit use of and reimburse-ment for UDM Reimbursement changes regularly andauthors recommend that clinicians refer to currentCenters for Medicare and Medicaid Services (CMS) re-imbursement policies (Table 1) [44] and commercial in-surance coverage benefits [50] as well as considervariations in costs across practice settings to stay up todate on changes Of note costs of appropriate UDMmay be offset by savings in overall health care (ie viaimprovement in care and reductions in drug misuseopioid use disorder and diversion) [51] but this relation-ship requires further study
Clinicians receive minimal education on UDM and oftenlack adequate knowledge of how to both choose an ap-propriate UDM test [52] and interpret complex results[53] Lack of understanding can lead to misinterpretationof UDM results failure to identify patterns of harmfuldrug use and inappropriate management of patientsClinicians may compromise patient care by denying ap-propriate treatment or discharging patients from theirpractice after inaccurately concluding that they are mis-using or diverting opioids owing to a false-positive orfalse-negative UDM result [5253]
With UDM as a current best practice and given its inher-ent complexities in clinical practice updated guidance isneeded The purpose of this consensus report is to pro-vide clinicians with a framework for practical and rational

[AAPM]) adjudicated any discrepancies to develop the fi-nal list of questions
1 Which UDM test(s) should be used and in whichpatients prescribed opioids for chronic pain shouldthe tests be used according to a medical literaturereview clinical experience clinical chemistry of drugtesting and practical considerations
2 How should patients undergoing UDM be stratifiedfor opioid misuse risk
3 How often should UDM occur in patients with lowmedium and high risk for opioid misuse or opioiduse disorder
For background the panel members identified existingguidelines that have been most influential in UDM inchronic pain practice Articles were obtained fromPubMed using the search terms urine drug testing andchronic pain Studies published from June 13 2012 (iethe date of the previous guidelines specific to UDM [40])to April 6 2016 (the date of the search) were includedSearch results were filtered to exclude narrative reviewscase reports studies involving nonurine matrices (egblood oral fluid hair) laboratory tests and any studieswith findings not relevant to the three selected questionson UDM Studies in patients with cancer pain were ex-cluded to narrow the patient population similar to otherguidelines [18ndash20] however this should not be construedas a recommendation to not perform UDM in patientsprescribed opioids for cancer-related chronic pain To ad-dress potential literature gaps additional references (egkey landmark studies) were identified through referencelists and by panelist recommendations
Using the process followed by the Centers for DiseaseControl and Prevention (CDC) Guideline for PrescribingOpioids for Chronic Pain [1854] an abbreviated Grading ofRecommendations Assessment Development andEvaluation (GRADE) methodology was performed Studieswere evaluated and graded as type 1 through 4 which gen-erally corresponded to the following study categories [54]
1 randomized controlled trials (RCTs) or observationalstudies with overwhelming evidence
2 RCTs with important limitations or observational stud-ies with exceptionally strong evidence
3 observational studies or RCTs with notable limitations
4 clinical experience and observations observationalstudies with important limitations or RCTs with sev-eral major limitations
Phase 2 Convening Expert Panel Members forInteractive Discussions and Voting to Reach Consensus
Consensus panel meetings for UDM occurred via web-based teleconferences on August 11 and 18 2016 for
a total of five hours Section leaders (JF JAG RCPand DPA selected by co-chairs to lead discussions)reviewed the literature and led interactive discussionsabout the main questions related to UDM before con-sensus on recommendations was reached with a modi-fied nominal group technique [5556] This consensusmethod was selected because of its demonstrated va-lidity long history of use and time efficiency as well asthe ability for all panelists to provide input [57] After ev-ery panelist provided an answer to a question panelistsvoted for their preferred answer if multiple options wereproposed Additional discussion cycles and voting wereperformed until consensus was reached
Phase 3 Preparation of the Consensus Report
The content of this report reflects an extensive review ofexisting UDM research and guidelines discussion fromseveral meetings and communications among the ex-pert panelists and consensus recommendationsPanelists reviewed and revised content in multiplestages of manuscript development before finalization
Results
Six recent guidelines that address UDM in patients withchronic pain were identified by panelists as most rele-vant to the three key questions The literature searchfound 85 studies pertaining to UDM 21 additional refer-ences were added to address gaps in the existing litera-ture on topics requested by panelists After filtering forrelevance to the three main questions (performed by aneditorial service directed by the authors) 41 referencesfrom the expanded literature search were included all ofwhich were graded for scientific merit as type 3 (lowquality) or 4 (lowest quality) by the authors Validationstudies even when well designed were not consideredequivalent to RCTs and were rated as lower quality
All graded references are included in the RelevantLiterature sections for each question Because of thelack of high-quality evidence addressing the priorityissues for this report recommendations were notassigned a strength category Recommendations(Figure 2) should be considered consensus opinionsbased on evolving evidence

assessing baseline opioid use and opioid misuse in al-most all patients with chronic pain being considered foropioids as well as for ongoing monitoring of patients re-ceiving opioids for chronic pain unless presumptivetesting is required by institutional or payer policies A ra-tional approach to choosing the most relevant analytes(ie substances to be tested) for UDM testing is pro-posed (in the Expert Panel Discussion section for ques-tion 1) and should be documented by the clinician
Existing Guidelines
In contrast to this expert panelrsquos recommendation pre-viously published guidelines suggest that patientsundergo presumptive testing with immunoassay whenthey are prescribed opioids for chronic pain[18202240] some guidelines specify that the testshould be POC [2040] Confirmatory definitive tests aregenerally reserved for resolving unexpected results fromimmunoassays [18202240] or for detecting specificopioids that cannot be identified with standard immu-noassays [18] According to the CDC [18] CMS [58]and other payer policies [5059] definitive testing is ap-propriate only when it affects clinical decision-makingand patient management The Washington State guide-lines suggest considering the following drugs for aUDM panel in addition to medications prescribed alco-hol amphetamines barbiturates benzodiazepinescannabinoids cocaine fentanyl methadone opiatesand oxycodone [22]
Relevant Literature
Surveys indicate that UDM in patients prescribedopioids for chronic pain varies widely (ie 19ndash636of patients receive UDM at some point during treatment[60ndash63] and 69ndash100 of clinicians administer UDM[295263ndash66]) which demonstrates a need for guid-ance Traditionally POC immunoassays have been usedfor initial screening in UDM because they provide rapidresults at relatively low cost [28] However false-positiveresults (eg 22 for opiate immunoassays [32]) can becaused by cross-reactivity [28] and false-negativeresults (eg 30 for opiate assays [32]) may occur be-cause of drug concentration cutoffs and cross-reactivityin particular among drugs in similar chemical classes[67] Some opioids and benzodiazepines are not welldetected by immunoassays [67]
Compared with immunoassays definitive testing candetect a greater number of compounds (eg variousbenzodiazepines [67ndash69]) and demonstrates higher sen-sitivity and specificity [70] The gold standard of defini-tive testing was considered to be GC-MS [71] but LC-MSMS has become a favored method [28] because itis associated with less drug interference and can beperformed with smaller urine volumes than for GC-MS[71] Validation of two new LC-MSMS methods wasidentified through our literature search [7273] As a ca-veat detection of metabolites of some prescriptionopioids (eg buprenorphine by certain routes ofadministration) or illicit substances (eg heroin) with

LC-MSMS is challenging in part because of insufficientsensitivity of tests and individual variation in drug metab-olism [7475]
Although (confirmatory) definitive testing is often used toverify unexpected immunoassay results recent evidencesuggests that it is more accurate than immunoassay atassessing patientsrsquo substance use at initial screening[76ndash78] A hybrid UDM approach in which each drugwas measured with either immunoassay or LC-MS(depending on which platform has better accuracy andspeed for each drug) reduced the need for confirmationtesting and time to results [79] In a study at a privatepain practice clinicians and patients discussed unex-pected results from initial immunoassay UDM and opennonjudgmental communication was emphasized thisapproach led to only 3 to 5 of cases requiring con-firmatory GC-MS testing [80] The clinical utility of a hy-brid immunoassayLC-MS approach and of effectivepatient communication to prevent the need for confir-matory GC-MS testing will need to be furtherestablished
Expert Panel Discussion
The panelists expressed concerns about limited sensitiv-ity and specificity as well as misinterpretation errors withclass-specific immunoassays especially in the primarycare setting The initial low cost of immunoassays maybe negated by their potential inaccuracy which can in-crease the downstream financial burden to confirm con-flicting or unexpected results and potentially increasecosts for additional treatments and office visits when apatient is inappropriately continued or discontinued fromopioids because of misinterpretation of results Definitivetesting although often more expensive than immunoas-say initially includes a more comprehensive panel ofsubstances and is more sensitive and specific fordetecting adherence to prescribed opioids and use ofother substances For these reasons several panelistsconsider definitive testing to be the most rational choicefor UDM and elect to use it exclusively for both prelimi-nary testing and follow-up testing when results are con-tested by the patient
The expert panel recognizes that not all clinicians havereliable access to definitive testing laboratories andsome payers reimburse for definitive testing only afteran immunoassay result is inconsistent with therapy Therecommendations in this consensus are intended to beconsidered together with practical clinical and payerconcerns When required by payers and institutionsimmunoassays may be sufficient for monitoring low-riskpatients particularly when clinicians and patients en-gage in open communication
Given the potentially high cost of definitive testing ratio-nal selection of analytes is recommended Appropriatesubstances to analyze for UDM include all controlled
substances (and selected noncontrolled coanalgesicssuch as antidepressants and anticonvulsants) that a pa-tient is prescribed as well as substances unexpectedlyfound at previous UDM Inclusion of additional medica-tions andor alcohol is driven by their potential for harm(ie risk-relevant testing) For identification of substan-ces most likely to be used and diverted consult recentnational survey results [81] and relevant geographic data[82] Greater numbers of analytes will likely need to betested for patients at higher risk for substance usedisorders
Complexities regarding UDM test properties necessitatethat clinicians have access to an expert (eg toxicolo-gist knowledgeable pain or addiction specialist pathol-ogist) when choosing the most appropriate test andinterpreting unexpected results Clinicians should alsobe aware of relevant state mandates regulations andguidelines [83] descriptions of UDM requirements bystate are available from state medical boards and theAAPM website (httpwwwpainmedorgadvocacystate-updates)
Question 2 How Should Patients Undergoing UDMBe Stratified for Opioid Misuse Risk
Expert Panel Recommendations
To guide UDM frequency assess and stratify patientswho are prescribed opioid therapy for chronic pain withthe following strategies
bull Perform a physical examination and obtain relevantpatient history for eventsdiagnoses and behaviorsthat have been shown to predict opioid misuse andopioid use disorder (eg history of substance use dis-orders psychiatric conditions sexual abuse) includinginformation from previous providers for patients trans-ferring care
bull Use validated tools to assess the risk for aberrantmedication-taking behavior opioid misuse opioid usedisorder and the potential for respiratory depressionoverdose
bull Check prescription drug monitoring programs(PDMPs) and previous UDM results when available
Existing Guidelines
Some guidelines [182022] recommend the use of riskassessment tools to stratify patients receiving opioidsthe Opioid Risk Tool (ORT) and Screener and OpioidAssessment for Patients with PainndashRevised (SOAPPVR -R)are frequently mentioned in other guidelines[18224084] Tools deemed most relevant by panelistson the basis of validation studies and use in practiceare described in Table 2 [18192284ndash94] There is aneed for further clinical validation of existing tools [19]and for development of newer and more accurate toolsthat incorporate additional risk factors [1895] Risk tools

are just one part of a comprehensive patient evaluation[2040]
Relevant Literature
Several tools for predicting and determining current risk ofaberrant medication-taking behaviors (eg lost prescrip-tion request for early refill) opioid misuse and opioid usedisorder are reported in the literature [96ndash99] In a painclinicndashbased study a semistructured clinical interview byan addiction psychologist was more sensitive than theORT Pain Medication Questionnaire and SOAPP-R atpredicting aberrant drug-related behavior [98] TheSOAPP-R showed the highest sensitivity of these self-report measures but may overestimate risk [98]
The use of external information (eg PDMPs) can alsoimprove patient management [100] In a university-based multidisciplinary pain management center misuseand diversion were detected more frequently by addingUDM andor a PDMP check to a baseline strategy ofcomparing patient reports and review of medicalrecords [101] However a systematic review of primarycare pain clinic and Veterans Administration (VA)Medical Center settings concluded that no single proce-dure or set of variables was sufficient to identify patientswith chronic pain who are at risk for opioid misuse orharmful substance use [97]
Expert Panel Discussion
The expert panelists suggest that patients be assessedfor risk of aberrant medication-taking behavior misuseand opioid use disorder to determine the frequency ofUDM A high-dose cutoff alone (eg 120-mg morphineequivalent dose per day [22]) was perceived as being in-adequate for identifying high-risk patients because highdoses may be appropriate to accommodate develop-ment of tolerance in specific patients [192187] In addi-tion patients predisposed to misuse may be at risk ofopioid use disorder or unsafe use even with low tomoderate doses
No specific risk assessment tool or behavioral assess-ment is recommended by panelists Clinicians are en-couraged to choose one or more of the many availabletools that match their preferences and can be incorpo-rated into their electronic medical records and workflow Understanding why specific factors predict risk ismore important than knowledge of the risk assessmenttools themselves (Figure 3 [1997102ndash107]) Risk strati-fication is not static and regular reevaluation of patientcircumstances (eg loss of a job divorce) is recom-mended An unexpected UDM result increases apatientrsquos risk of misuse and opioid use disorder neces-sitates more frequent testing and prompts reconsidera-tion of whether to modify opioid therapy or refer thepatient to a pain or addiction specialist
A comprehensive evaluation to assess the presence orrisk of misuse and opioid use disorder includes ques-tions about patientsrsquo history of substance use disordersand current clinical characteristics (eg from a physicalexamination) input from patientsrsquo family members andother health care providers (eg psychiatrists previouspain specialists) and pill counts Behaviors that may in-dicate increased likelihood of misuse or opioid use dis-order include requests for early refills [108]unauthorized dose escalations [109] and use of anotherindividualrsquos medication [109] Substance use disorder isgenerally associated with one or more of the four ldquoCsrdquo(ie impaired Control over use Compulsive useContinued use despite harm and Craving) [110]
A few simple questions (eg single-item screeningquestions [SISQs] for alcohol and drug use [93111]) fol-lowed by a discussion with patients is an efficient wayfor clinicians to incorporate risk assessment into theirpractice Reviewing a patientrsquos history of controlled sub-stance prescriptions in the PDMP is another method forassessing potential opioid misuse or substance use dis-order Clinicians should be aware of their statersquos regula-tions recommendations and resources regardingPDMPs [112] All states have or are planning to imple-ment a PDMP but reporting times vary and not everyprovider is required to participate in PDMPs in all states[112ndash114] The Comprehensive Addiction and RecoveryAct of 2016 is intended to improve the efficiency ofthese programs to track prescription drug use and helpprevent inappropriate use [115] Despite their inconsis-tencies PDMPs (when available) have become standardof care as part of patient risk evaluation WhetherPDMP data will predict aberrant behaviors or other ad-verse outcomes is not yet known and represents a gapin the science and an unmet need
Question 3 How Often Should UDM Occur in Patientswith Low Medium and High Risk for Opioid Misuseor Opioid Use Disorder
Expert Panel Recommendation
Perform UDM at baseline in patients prescribed opioidsfor chronic pain During ongoing monitoring performUDM at least annually for low-risk patients two or moretimes per year for moderate-risk patients and three ormore times per year for high-risk patients Additionalmonitoring can be performed at any risk level as fre-quently as necessary according to clinical judgment
Existing Guidelines
Recent guidelines recommend UDM at least annually forall patients regardless of risk [18] every six months totwo years for patients at low risk for opioid misuse oropioid use disorder [202240] one to three times peryear for moderate-risk patients [2022] and at least twoto four times per year for high-risk patients [202240]

The CDC Guideline for Prescribing Opioids for ChronicPain does not recommend tailoring the monitoringschedule according to risk because tools that predictharmful use lack sufficient accuracy [18] Several guide-lines [182122] suggest periodic UDM testing duringscheduled visits truly random testing outside of sched-uled clinic visits may not be feasible in many settings(eg primary care) or appropriate for all patients [18]
Relevant Literature
The identified studies related to UDM frequency do notdifferentiate strategies for low- moderate- and high-risklevels Nevertheless clinical trials assessing the effectsof UDM on outcomes are particularly relevant to deci-sions regarding frequency of monitoring (SupplementaryTable 1) Adherence to prescribed opioids is higher withmore frequent UDM according to a retrospective analy-sis of patients with chronic pain in private practices[116] In two prospective trials at an interventional painmanagement practice adherence monitoring that in-cluded random UDM was associated with reductions inindicators of opioid misuse (determined via periodicchart review UDM pill counts and verification of infor-mation with treating clinicians and pharmacies) [24] andillicit drug use (determined via UDM) [117] In anotherstudy a comprehensive risk reduction strategy includ-ing UDM led to decreased pill confiscations by law en-forcement agents and improved primary care providersrsquoperceptions of the overall quality of pain management[118] A structured program designed to support pri-mary care providers with chronic pain management ledto a greater-than-two-fold increase in UDM 22 months
after initiation of the program which was associatedwith a 727 relative decrease in total emergency de-partment (ED) visits and a 596 relative decrease inunscheduled primary care provider visits per patient onaverage [119]
The main negative clinical consequence of UDMreported in the literature was a lower likelihood ofpatients attending a second visit at an urban academicpain clinic after urine testing was used in the first officevisit [120] Individuals with positive test results for an il-licit substance were less likely to attend the second visitthan those with a negative result [120] Although thisstudy suggests that UDM at first visit may hinderpatient-clinician trust patient response to UDM mayvary by clinical setting by how the rationale for UDM isexplained to the patient and by the degree to whichUDM becomes routine in clinical practice
Many studies showed significant benefits of UDM how-ever a few did not No association between UDM and all-cause mortality was found in VA patients [121] althoughan association was not necessarily expected in this sam-ple of patients with a high burden of comorbiditiesAnother study conducted in a large health care systemshowed that an opioid risk reduction initiative (includingrecommendations on UDM) increased use of UDM with-out affecting rates of unexpected results (eg negative forprescribed opioids or positive for cannabis) [122]
Several studies and surveys of physicians (eg pain andaddiction specialists) nurses PAs and other health careprofessionals mainly from pain practices and academiccenters have assessed the frequency of UDM during

opioid therapy for chronic pain [296580123124]which provides context for recommendations on fre-quency Patients with chronic pain received an averageof 34 UDM tests per year according to a 2007 study ina Kentucky private pain practice [80] The frequency ofUDM testing increased by an average of 34 yearlyfrom 2005 to 2008 in a clinical laboratory serving a largeacademic center [123] Surveys indicated that individualpain and addiction experts differed in their frequency ofUDM use from testing at every office visit to yearly[2965] although most preferred random testing[65124] As a caveat these surveys did not focus onprimary care settings
Expert Panel Discussion
The expert panel did not specify how the relative riskcategories should be determined aside from suggestingseveral potential risk assessment tools and strategies(see the Question 2 section) Baseline UDM testing is tobe performed either before initiation of opioid therapyor for those continuing opioid therapy from another pro-vider within three months of the first office visit If thepatient received UDM testing from another providerwithin the previous year and the results were consistentwith prescribed opioid therapy no immediate retestingmay be needed to continue therapy
Regular UDM is recommended even in low-risk patientsbecause their circumstancesbehaviors can change overthe course of therapy Patients at especially low risk(eg receiving low-dose as-needed opioids) mayrequire infrequent UDM (eg every two years) Moderate-risk patients may become higher or lower risk dependingon their environment and stressors intense monitoring isusually not required in these patients but periodic reevalu-ation of their situationsrisk factors is appropriate
High-risk patients require more frequent individualizedUDM testing than those at low or moderate risk al-though the evidence supporting the effectiveness of in-tense monitoring is weak Most primary care providerscan best care for high-risk patients by referring them toa pain and addiction specialist when available Primarycare clinicians who are trained in chronic pain manage-ment utilize UDM are experienced in interpreting UDMresults and have access to consultant toxicologists maybe able to appropriately care for high-risk patientsandor comanage them with a pain specialist Currentguidelines for UDM in patients with substance usedisorder recommend use of personalized testingregimens [28]
Additional Expert Panel Recommendations andDiscussion
UDM Rationale
Clinicians are encouraged to include information relatedto UDM in patient-provider agreements and explain to
patients that the primary goals of UDM are to improvethe safety and effectiveness of therapy by monitoringadherence Furthermore UDM is strongly recommendedas part of a universal precautions approach [125]Consistent UDM results provide objective data to sup-port decision-making during chronic opioid therapy
UDM Process
The panelists recommend that clinicians discuss theUDM process openly with patients as they do with allother clinical testing and document the time of lastmedication use before urine collection Unexpectedresults may be caused by laboratory errors (eg mislab-eling) or by sample adulteration including substitution ofsynthetic or another individualrsquos urine Signs of tamper-ing include temperature outside the normal range of90 F to 100 F within four minutes of sample collectionpH outside the normal range of 45 to 80 low creati-nine concentration (ie 20 mgdL) low specific gravity(ie 1003) presence of adulterants or detection ofparent drug without metabolites [28] Variation in metab-olite levels may also result from pharmacogenetic anom-alies or drug-drug interactions affecting drugmetabolism [28126]
Strategies to prevent sample tampering depend on theclinical setting and can include observed collection(viewed as overly invasive of a patientrsquos privacy) achain-of-custody protocol (ie documentation for han-dling of the specimen) and a truly random collection(ie a protocol to notify the patients of required testingwithin a set period) [28] Although observed urine sam-ple collection at pain clinics has been recommended[83] this practice and chain-of-custody protocols aretypically not followed Despite risk-mitigation strategiesdedicated individuals can still manipulate their UDMsamples or consume prescribed medication before of-fice visits to conceal misuse or diversion Patients withan opioid use disorder may not be able to control theirdrug use to avoid unexpected UDM results despitescheduled collection
Alcohol Screening
For patients with a substance use disorder alcohol maybe problematic and prohibited in any amount for otherpatients with chronic pain only high-risk alcohol use(eg binge drinking) is a concern Many opioids includeblack box warnings about the concurrent use of alcoholbecause of the potential for fatal overdose [127] Onereviewed guideline recommends screening for alcoholwith UDM in patients with chronic pain [22] ethyl glucu-ronide ethyl sulfate or ethanol in UDM indicates alcoholuse [128] As a caveat immunoassay and definitiveUDM may not differentiate between alcoholic beveragesand alcohol-containing medications mouthwashes andhand sanitizers [28] Instead of UDM the panelists

recommend the SISQ ldquoHow many times in the past yearhave you had (five or more drinks [men] four or moredrinks [women]) in a dayrdquo from the National Institute onAlcohol Abuse and Alcoholism [111] to identify un-healthy alcohol use as this question is simple to admin-ister and is validated [129] In primary care settings thesensitivity of the alcohol SISQ for identifying alcohol usedisorder is 88 and the specificity is 84 [130]
Cannabis Screening
Practices for cannabis screening vary [131] individualprescribers can decide whether detecting cannabis byUDM is appropriate by consulting local laws [132133]and common practice as well as by considering theadvantagesdisadvantages discussed below At the timeof this publication cannabis is federally illegal (ie clas-sified by the US Drug Enforcement Administration asSchedule 1 under the Controlled Substances Act) butseveral states have passed legislation to decriminalize itfor medical andor recreational use [131ndash134] The CDCGuideline for Prescribing Opioids for Chronic Pain indi-cates that the clinical implications of a positive UDM re-sult for cannabis are uncertain [18] the VAUSDepartment of Defense guidelines estimate the length oftime it can be detected in urine [21] and theWashington State guidelines suggest implementing anoffice policy for patients who use cannabis [22] Theseguidelines [182122] and this consensus report do notprovide formal graded recommendations for or againstUDM screening for cannabis or for interpretation of theresults
Clinicians who avoid cannabis testing may miss criticalinformation that could inform patient monitoring and im-prove safety Data from Colorado indicate increased EDvisits hospitalizations and proportions of fatal motor ve-hicle accidents related to cannabis intoxication after de-criminalization [134ndash136] Illegal use of cannabis is amarker for opioid misuse and substance use disorders[137] and a rationale to classify a patient as high riskAnother concern is that patients may divert prescriptionopioids to purchase cannabis
If clinicians choose to assess patientsrsquo nonprescriptioncannabinoid use there is a validated SISQ for drugs in-cluding cannabis (ie ldquoHow many times in the past yearhave you used an illegal drug or used a prescriptionmedication for nonmedical reasonsrdquo) [93] with a sensi-tivity of 97 and a specificity of 79 for substance usedisorders in primary care settings [130] Although somemetabolites of synthetic cannabinoids (eg spice) canbe analyzed with specialized immunoassayschromatographyspectrometry-based assays are betterfor assessing the many emerging synthetic cannabi-noids and their metabolites [138]
A subject of ongoing debate is whether co-administration of opioids and cannabis (used
recreationally or medically) is safe or reasonable for clini-cians to allow Cannabis is increasingly accepted formedical purposes especially for cancer pain syn-dromes However allowing patients with chronic pain touse cannabis is a potential liability for clinicians (includ-ing pharmacists) regardless of the drugrsquos legal status intheir state [139] The safety of cannabis for patients withchronic pain is not clearly established [140] and little isknown regarding the safety of concurrent use withopioids apart from the potential opioid-sparing effects ofcannabis [141] The composition and dose of the manyactive components in cannabis vary widely [133142]which leads to variable toxicity [143] and complicatessafety studies Cannabinoids may inhibit cytochromeP450 2D6 [144] (involved in opioid metabolism [145])and therefore affect both the efficacy of opioids and theability to detect metabolites in UDM The panelists pro-posed that a single clinician be responsible for manag-ing both opioid and cannabis use in states where thedrug has been decriminalized and the benefits of con-current use outweigh the risks
Interpreting UDM Results and Implications forChanging Clinical Practice
The panelists believe that clinicians should follow manu-facturer instructions for specific POC UDM tests and di-rect any questions about interpreting results to anexpert in toxicology or clinical pathology Laboratoriesperforming UDM have a responsibility to provide cleartest results answer questions and offer support on clin-ical decisions When clinicians are confronted with un-expected results potential causes for false-positive andfalse-negative results (eg quinolone antibiotics tolme-tin Figure 1) are important to investigate A summary ofcommunications and discussions about results with thelaboratory and other experts can be included in themedical record to document the medical necessity oftesting and related clinical decision-making
Communications with patients about the purpose andresults of UDM should be nonjudgmental and nonpuni-tive and should focus on safety and risks associatedwith misuse and opioid use disorder To avoid unex-pected results open discussion with patients is recom-mended and may include asking questions such as ldquoIfwe test you today what will we find in your urine Willthere be any surprisesrdquo Development of a plan to ad-dress UDM results that are inconsistent with therapy issuggested to mitigate safety risks for patients and po-tential regulatory board sanctions for clinicians Of noteUDM results that are consistent with prescribed opioidscannot differentiate among appropriate use occasionaluse or misuse and opioid use disorder negative UDMresults for prescribed opioids cannot distinguishbetween infrequent need for medicine overuse and run-ning out falsification of the urine sample and diversionResults of UDM are only part of the clinical information

(eg including patient history) that must be consideredbefore a treatment plan is changed
Detailed recommendations on proper opioid prescribingand appropriate changes to patient care after unex-pected UDM results are outside the scope of this con-sensus report but are discussed in other guidelines[18202240] In brief options to address unexpectedUDM results include open and nonjudgmental discus-sions with patients additional confirmation testing in-creased monitoring a switch to a nonopioid painmedication or referral for treatment of an opioid usedisorder [18202240]
Three studies from the Philadelphia VA Medical Center in-vestigated how UDM results affected provider behavior[119146147] additional research to determine how UDMresults should influence patientsrsquo therapy is warranted Inthe absence of this information a follow-up consensusmeeting to evaluate expert opinion was suggested
Conclusions
In summary the expert panel made the following rec-ommendations regarding UDM (Figure 2)
1 Use definitive UDM testing (eg with GC-MS LC-MS or LC-MSMS) as the most clinically appropriatemethod for assessing baseline opioid use and opioidmisuse in most patients with chronic pain being con-sidered for opioids as well as for ongoing monitoringof patients receiving opioids for chronic pain unlesspresumptive testing is required by institutional orpayer policies A rational approach to choosing themost relevant analytes for UDM testing is proposedand should be documented by the clinician
2 To guide UDM frequency assess and stratify patientsprescribed opioid therapy for chronic pain with thefollowing strategies
bull perform a physical examination and obtain relevantpatient history for eventsdiagnoses and behaviorsthat have been shown to predict opioid misuseand opioid use disorder (eg history of substanceuse disorders psychiatric conditions sexual abuse)including information from previous providers forpatients transferring care
bull use validated tools to assess risk for aberrantmedication-taking behavior opioid misuse opioiduse disorder and the potential for respiratory de-pressionoverdose
bull check PDMPs and previous UDM results whenavailable
3 Perform UDM at baseline in patients receiving opioidsfor chronic pain During ongoing monitoring performUDM at least annually for low-risk patients two ormore times per year for moderate-risk patients andthree or more times per year for high-risk patientsAdditional monitoring can be performed as frequently
as necessary according to clinical judgment (egworrisome patient behavior related to the prescribedmedication)
The recommendations in this consensus report are meantto provide practical advice on implementing rational UDMacross a broad range of clinical practices in a patient-centric manner Some clinicians may not have access toappropriate resources to perform routine definitive UDMor to refer patients to pain specialists alternatives are pro-vided in the expert panel discussion sections Higher-quality studies on patient outcomes with UDM areneeded As a next step a consensus recommendationinitiative similar to this one that discusses appropriate clini-cian actions in response to test results that are inconsis-tent with prescribed therapy is warranted

term conveys an ongoing process rather than a singletesting event and UDM has a nonpunitive patient-centric connotation as variations on the term drugtesting may be associated with punitive intent in lay lan-guage Diversion is used in this consensus report tomean a transfer (eg giving selling) of prescriptiondrugs for unlawful distribution or use [20] Misuse is de-fined as taking medications in a manner other than pre-scribed even when treating a medical condition [2028]Substance use disorders are a cluster of cognitive be-havioral and physiological symptoms indicating contin-ued use of a psychoactive substance (eg to getldquohighrdquo) despite negative consequences and harm[2930] Opioid use disorder is characterized by signsand symptoms of compulsive prolonged self-administration of opioids in doses exceeding a medicallyappropriate amount or for no legitimate medical purposedespite clinically and functionally significant impairmentssuch as health problems and failure to meet major so-cial responsibilities [30] Because the colloquial labelsldquodirtyrdquo and ldquocleanrdquo to describe UDM results can stigma-tize patients and reduce their likelihood of seeking andaccepting recommended help [31] ldquoinconsistent withtherapyrdquo ldquounexpected resultsrdquo ldquoconsistent withtherapyrdquo and ldquoexpected resultsrdquo are used in this report
Description of UDM Technologies
A presumptive UDM test is a screening immunoassaythat is relatively inexpensive can be used in the office atpoint of care (POC) and produces a rapid result (egwithin minutes) [28] Clinicians may be unfamiliar withthe characteristics of immunoassays which have vari-able sensitivity and specificity (eg 0ndash50 missedpositive results and 11ndash100 incorrectly identifiedpositive results across drug classes) [32] and maytherefore miss substances that can lead to inaccurateimmunoassay results (Figure 1) [33ndash40] The classicldquourine screen testsrdquo are often enzyme immunoassaysthat target amphetaminesmethamphetamines canna-bis cocaine phencyclidine and opioids (ie theldquofederal fiverdquo [41]) and are based on a specific antidrugantibody reaction [42] Opiate immunoassays can moreaccurately detect naturally occurring opiate alkaloids(ie morphine codeine) than commonly prescribed syn-thetic (eg fentanyl methadone) and semisynthetic(eg buprenorphine oxycodone oxymorphone hydro-morphone) opioids [42] Immunoassays are at bestsemiquantitative (ie an estimate of levels only) becauseof cross-reaction across multiple drugs [43] Reasonablysensitive options are now available for testing manycommon drug classes [43]
Definitive UDM can be used for initial or confirmatorytesting (ie to verify the results of a presumptive testthat are contested by the patient) and includes qualita-tive or quantitative gas chromatography (GC)ndashmassspectrometry (MS) liquid chromatography (LC)ndashMS andLCndashtandem MS (LC-MSMS) technologies [2844]
Definitive testing is often more specific and usually moresensitive than immunoassay for the substances testedbut it is also more costly [28] Although some immuno-assays can detect chemical adulterants (ie any sub-stance that lessens validity of testing) [45] definitivetesting is less susceptible to adulterants and decreasesthe likelihood of inaccurate or false results [28]Definitive testing accurately identifies metabolites to con-firm that the parent drug was indeed ingested [28] andcan also detect potentially abnormal opioid metabolism[46] Metabolite results may be confusing to clinicianswho are not aware that some prescribed opioids aremetabolites of others (eg oxymorphone is a metaboliteof oxycodone and hydromorphone is a metabolite ofhydrocodone [18])
UDM Challenges and Unmet Needs
Although the effectiveness of UDM as a risk mitigationtool or strategy against overdose opioid use disorderand diversion has been inadequately studied nationalguidelines from the last decade [18ndash2240] have recom-mended UDM as best practice in patients prescribedopioids for chronic pain These guidelines usually sug-gest initial immunoassay before (confirmatory) definitiveUDM because of cost concerns [182040]
Potential conflicts of interest (eg clinic owners finan-cially benefiting from frequent POC testing [47] andcommercial laboratories promoting the use of definitiveUDM beyond clinically appropriate thresholds) have ledpayers to increase scrutiny of UDM [4849] Current re-strictive payer policies can limit use of and reimburse-ment for UDM Reimbursement changes regularly andauthors recommend that clinicians refer to currentCenters for Medicare and Medicaid Services (CMS) re-imbursement policies (Table 1) [44] and commercial in-surance coverage benefits [50] as well as considervariations in costs across practice settings to stay up todate on changes Of note costs of appropriate UDMmay be offset by savings in overall health care (ie viaimprovement in care and reductions in drug misuseopioid use disorder and diversion) [51] but this relation-ship requires further study
Clinicians receive minimal education on UDM and oftenlack adequate knowledge of how to both choose an ap-propriate UDM test [52] and interpret complex results[53] Lack of understanding can lead to misinterpretationof UDM results failure to identify patterns of harmfuldrug use and inappropriate management of patientsClinicians may compromise patient care by denying ap-propriate treatment or discharging patients from theirpractice after inaccurately concluding that they are mis-using or diverting opioids owing to a false-positive orfalse-negative UDM result [5253]
With UDM as a current best practice and given its inher-ent complexities in clinical practice updated guidance isneeded The purpose of this consensus report is to pro-vide clinicians with a framework for practical and rational

[AAPM]) adjudicated any discrepancies to develop the fi-nal list of questions
1 Which UDM test(s) should be used and in whichpatients prescribed opioids for chronic pain shouldthe tests be used according to a medical literaturereview clinical experience clinical chemistry of drugtesting and practical considerations
2 How should patients undergoing UDM be stratifiedfor opioid misuse risk
3 How often should UDM occur in patients with lowmedium and high risk for opioid misuse or opioiduse disorder
For background the panel members identified existingguidelines that have been most influential in UDM inchronic pain practice Articles were obtained fromPubMed using the search terms urine drug testing andchronic pain Studies published from June 13 2012 (iethe date of the previous guidelines specific to UDM [40])to April 6 2016 (the date of the search) were includedSearch results were filtered to exclude narrative reviewscase reports studies involving nonurine matrices (egblood oral fluid hair) laboratory tests and any studieswith findings not relevant to the three selected questionson UDM Studies in patients with cancer pain were ex-cluded to narrow the patient population similar to otherguidelines [18ndash20] however this should not be construedas a recommendation to not perform UDM in patientsprescribed opioids for cancer-related chronic pain To ad-dress potential literature gaps additional references (egkey landmark studies) were identified through referencelists and by panelist recommendations
Using the process followed by the Centers for DiseaseControl and Prevention (CDC) Guideline for PrescribingOpioids for Chronic Pain [1854] an abbreviated Grading ofRecommendations Assessment Development andEvaluation (GRADE) methodology was performed Studieswere evaluated and graded as type 1 through 4 which gen-erally corresponded to the following study categories [54]
1 randomized controlled trials (RCTs) or observationalstudies with overwhelming evidence
2 RCTs with important limitations or observational stud-ies with exceptionally strong evidence
3 observational studies or RCTs with notable limitations
4 clinical experience and observations observationalstudies with important limitations or RCTs with sev-eral major limitations
Phase 2 Convening Expert Panel Members forInteractive Discussions and Voting to Reach Consensus
Consensus panel meetings for UDM occurred via web-based teleconferences on August 11 and 18 2016 for
a total of five hours Section leaders (JF JAG RCPand DPA selected by co-chairs to lead discussions)reviewed the literature and led interactive discussionsabout the main questions related to UDM before con-sensus on recommendations was reached with a modi-fied nominal group technique [5556] This consensusmethod was selected because of its demonstrated va-lidity long history of use and time efficiency as well asthe ability for all panelists to provide input [57] After ev-ery panelist provided an answer to a question panelistsvoted for their preferred answer if multiple options wereproposed Additional discussion cycles and voting wereperformed until consensus was reached
Phase 3 Preparation of the Consensus Report
The content of this report reflects an extensive review ofexisting UDM research and guidelines discussion fromseveral meetings and communications among the ex-pert panelists and consensus recommendationsPanelists reviewed and revised content in multiplestages of manuscript development before finalization
Results
Six recent guidelines that address UDM in patients withchronic pain were identified by panelists as most rele-vant to the three key questions The literature searchfound 85 studies pertaining to UDM 21 additional refer-ences were added to address gaps in the existing litera-ture on topics requested by panelists After filtering forrelevance to the three main questions (performed by aneditorial service directed by the authors) 41 referencesfrom the expanded literature search were included all ofwhich were graded for scientific merit as type 3 (lowquality) or 4 (lowest quality) by the authors Validationstudies even when well designed were not consideredequivalent to RCTs and were rated as lower quality
All graded references are included in the RelevantLiterature sections for each question Because of thelack of high-quality evidence addressing the priorityissues for this report recommendations were notassigned a strength category Recommendations(Figure 2) should be considered consensus opinionsbased on evolving evidence

assessing baseline opioid use and opioid misuse in al-most all patients with chronic pain being considered foropioids as well as for ongoing monitoring of patients re-ceiving opioids for chronic pain unless presumptivetesting is required by institutional or payer policies A ra-tional approach to choosing the most relevant analytes(ie substances to be tested) for UDM testing is pro-posed (in the Expert Panel Discussion section for ques-tion 1) and should be documented by the clinician
Existing Guidelines
In contrast to this expert panelrsquos recommendation pre-viously published guidelines suggest that patientsundergo presumptive testing with immunoassay whenthey are prescribed opioids for chronic pain[18202240] some guidelines specify that the testshould be POC [2040] Confirmatory definitive tests aregenerally reserved for resolving unexpected results fromimmunoassays [18202240] or for detecting specificopioids that cannot be identified with standard immu-noassays [18] According to the CDC [18] CMS [58]and other payer policies [5059] definitive testing is ap-propriate only when it affects clinical decision-makingand patient management The Washington State guide-lines suggest considering the following drugs for aUDM panel in addition to medications prescribed alco-hol amphetamines barbiturates benzodiazepinescannabinoids cocaine fentanyl methadone opiatesand oxycodone [22]
Relevant Literature
Surveys indicate that UDM in patients prescribedopioids for chronic pain varies widely (ie 19ndash636of patients receive UDM at some point during treatment[60ndash63] and 69ndash100 of clinicians administer UDM[295263ndash66]) which demonstrates a need for guid-ance Traditionally POC immunoassays have been usedfor initial screening in UDM because they provide rapidresults at relatively low cost [28] However false-positiveresults (eg 22 for opiate immunoassays [32]) can becaused by cross-reactivity [28] and false-negativeresults (eg 30 for opiate assays [32]) may occur be-cause of drug concentration cutoffs and cross-reactivityin particular among drugs in similar chemical classes[67] Some opioids and benzodiazepines are not welldetected by immunoassays [67]
Compared with immunoassays definitive testing candetect a greater number of compounds (eg variousbenzodiazepines [67ndash69]) and demonstrates higher sen-sitivity and specificity [70] The gold standard of defini-tive testing was considered to be GC-MS [71] but LC-MSMS has become a favored method [28] because itis associated with less drug interference and can beperformed with smaller urine volumes than for GC-MS[71] Validation of two new LC-MSMS methods wasidentified through our literature search [7273] As a ca-veat detection of metabolites of some prescriptionopioids (eg buprenorphine by certain routes ofadministration) or illicit substances (eg heroin) with

LC-MSMS is challenging in part because of insufficientsensitivity of tests and individual variation in drug metab-olism [7475]
Although (confirmatory) definitive testing is often used toverify unexpected immunoassay results recent evidencesuggests that it is more accurate than immunoassay atassessing patientsrsquo substance use at initial screening[76ndash78] A hybrid UDM approach in which each drugwas measured with either immunoassay or LC-MS(depending on which platform has better accuracy andspeed for each drug) reduced the need for confirmationtesting and time to results [79] In a study at a privatepain practice clinicians and patients discussed unex-pected results from initial immunoassay UDM and opennonjudgmental communication was emphasized thisapproach led to only 3 to 5 of cases requiring con-firmatory GC-MS testing [80] The clinical utility of a hy-brid immunoassayLC-MS approach and of effectivepatient communication to prevent the need for confir-matory GC-MS testing will need to be furtherestablished
Expert Panel Discussion
The panelists expressed concerns about limited sensitiv-ity and specificity as well as misinterpretation errors withclass-specific immunoassays especially in the primarycare setting The initial low cost of immunoassays maybe negated by their potential inaccuracy which can in-crease the downstream financial burden to confirm con-flicting or unexpected results and potentially increasecosts for additional treatments and office visits when apatient is inappropriately continued or discontinued fromopioids because of misinterpretation of results Definitivetesting although often more expensive than immunoas-say initially includes a more comprehensive panel ofsubstances and is more sensitive and specific fordetecting adherence to prescribed opioids and use ofother substances For these reasons several panelistsconsider definitive testing to be the most rational choicefor UDM and elect to use it exclusively for both prelimi-nary testing and follow-up testing when results are con-tested by the patient
The expert panel recognizes that not all clinicians havereliable access to definitive testing laboratories andsome payers reimburse for definitive testing only afteran immunoassay result is inconsistent with therapy Therecommendations in this consensus are intended to beconsidered together with practical clinical and payerconcerns When required by payers and institutionsimmunoassays may be sufficient for monitoring low-riskpatients particularly when clinicians and patients en-gage in open communication
Given the potentially high cost of definitive testing ratio-nal selection of analytes is recommended Appropriatesubstances to analyze for UDM include all controlled
substances (and selected noncontrolled coanalgesicssuch as antidepressants and anticonvulsants) that a pa-tient is prescribed as well as substances unexpectedlyfound at previous UDM Inclusion of additional medica-tions andor alcohol is driven by their potential for harm(ie risk-relevant testing) For identification of substan-ces most likely to be used and diverted consult recentnational survey results [81] and relevant geographic data[82] Greater numbers of analytes will likely need to betested for patients at higher risk for substance usedisorders
Complexities regarding UDM test properties necessitatethat clinicians have access to an expert (eg toxicolo-gist knowledgeable pain or addiction specialist pathol-ogist) when choosing the most appropriate test andinterpreting unexpected results Clinicians should alsobe aware of relevant state mandates regulations andguidelines [83] descriptions of UDM requirements bystate are available from state medical boards and theAAPM website (httpwwwpainmedorgadvocacystate-updates)
Question 2 How Should Patients Undergoing UDMBe Stratified for Opioid Misuse Risk
Expert Panel Recommendations
To guide UDM frequency assess and stratify patientswho are prescribed opioid therapy for chronic pain withthe following strategies
bull Perform a physical examination and obtain relevantpatient history for eventsdiagnoses and behaviorsthat have been shown to predict opioid misuse andopioid use disorder (eg history of substance use dis-orders psychiatric conditions sexual abuse) includinginformation from previous providers for patients trans-ferring care
bull Use validated tools to assess the risk for aberrantmedication-taking behavior opioid misuse opioid usedisorder and the potential for respiratory depressionoverdose
bull Check prescription drug monitoring programs(PDMPs) and previous UDM results when available
Existing Guidelines
Some guidelines [182022] recommend the use of riskassessment tools to stratify patients receiving opioidsthe Opioid Risk Tool (ORT) and Screener and OpioidAssessment for Patients with PainndashRevised (SOAPPVR -R)are frequently mentioned in other guidelines[18224084] Tools deemed most relevant by panelistson the basis of validation studies and use in practiceare described in Table 2 [18192284ndash94] There is aneed for further clinical validation of existing tools [19]and for development of newer and more accurate toolsthat incorporate additional risk factors [1895] Risk tools

are just one part of a comprehensive patient evaluation[2040]
Relevant Literature
Several tools for predicting and determining current risk ofaberrant medication-taking behaviors (eg lost prescrip-tion request for early refill) opioid misuse and opioid usedisorder are reported in the literature [96ndash99] In a painclinicndashbased study a semistructured clinical interview byan addiction psychologist was more sensitive than theORT Pain Medication Questionnaire and SOAPP-R atpredicting aberrant drug-related behavior [98] TheSOAPP-R showed the highest sensitivity of these self-report measures but may overestimate risk [98]
The use of external information (eg PDMPs) can alsoimprove patient management [100] In a university-based multidisciplinary pain management center misuseand diversion were detected more frequently by addingUDM andor a PDMP check to a baseline strategy ofcomparing patient reports and review of medicalrecords [101] However a systematic review of primarycare pain clinic and Veterans Administration (VA)Medical Center settings concluded that no single proce-dure or set of variables was sufficient to identify patientswith chronic pain who are at risk for opioid misuse orharmful substance use [97]
Expert Panel Discussion
The expert panelists suggest that patients be assessedfor risk of aberrant medication-taking behavior misuseand opioid use disorder to determine the frequency ofUDM A high-dose cutoff alone (eg 120-mg morphineequivalent dose per day [22]) was perceived as being in-adequate for identifying high-risk patients because highdoses may be appropriate to accommodate develop-ment of tolerance in specific patients [192187] In addi-tion patients predisposed to misuse may be at risk ofopioid use disorder or unsafe use even with low tomoderate doses
No specific risk assessment tool or behavioral assess-ment is recommended by panelists Clinicians are en-couraged to choose one or more of the many availabletools that match their preferences and can be incorpo-rated into their electronic medical records and workflow Understanding why specific factors predict risk ismore important than knowledge of the risk assessmenttools themselves (Figure 3 [1997102ndash107]) Risk strati-fication is not static and regular reevaluation of patientcircumstances (eg loss of a job divorce) is recom-mended An unexpected UDM result increases apatientrsquos risk of misuse and opioid use disorder neces-sitates more frequent testing and prompts reconsidera-tion of whether to modify opioid therapy or refer thepatient to a pain or addiction specialist
A comprehensive evaluation to assess the presence orrisk of misuse and opioid use disorder includes ques-tions about patientsrsquo history of substance use disordersand current clinical characteristics (eg from a physicalexamination) input from patientsrsquo family members andother health care providers (eg psychiatrists previouspain specialists) and pill counts Behaviors that may in-dicate increased likelihood of misuse or opioid use dis-order include requests for early refills [108]unauthorized dose escalations [109] and use of anotherindividualrsquos medication [109] Substance use disorder isgenerally associated with one or more of the four ldquoCsrdquo(ie impaired Control over use Compulsive useContinued use despite harm and Craving) [110]
A few simple questions (eg single-item screeningquestions [SISQs] for alcohol and drug use [93111]) fol-lowed by a discussion with patients is an efficient wayfor clinicians to incorporate risk assessment into theirpractice Reviewing a patientrsquos history of controlled sub-stance prescriptions in the PDMP is another method forassessing potential opioid misuse or substance use dis-order Clinicians should be aware of their statersquos regula-tions recommendations and resources regardingPDMPs [112] All states have or are planning to imple-ment a PDMP but reporting times vary and not everyprovider is required to participate in PDMPs in all states[112ndash114] The Comprehensive Addiction and RecoveryAct of 2016 is intended to improve the efficiency ofthese programs to track prescription drug use and helpprevent inappropriate use [115] Despite their inconsis-tencies PDMPs (when available) have become standardof care as part of patient risk evaluation WhetherPDMP data will predict aberrant behaviors or other ad-verse outcomes is not yet known and represents a gapin the science and an unmet need
Question 3 How Often Should UDM Occur in Patientswith Low Medium and High Risk for Opioid Misuseor Opioid Use Disorder
Expert Panel Recommendation
Perform UDM at baseline in patients prescribed opioidsfor chronic pain During ongoing monitoring performUDM at least annually for low-risk patients two or moretimes per year for moderate-risk patients and three ormore times per year for high-risk patients Additionalmonitoring can be performed at any risk level as fre-quently as necessary according to clinical judgment
Existing Guidelines
Recent guidelines recommend UDM at least annually forall patients regardless of risk [18] every six months totwo years for patients at low risk for opioid misuse oropioid use disorder [202240] one to three times peryear for moderate-risk patients [2022] and at least twoto four times per year for high-risk patients [202240]

The CDC Guideline for Prescribing Opioids for ChronicPain does not recommend tailoring the monitoringschedule according to risk because tools that predictharmful use lack sufficient accuracy [18] Several guide-lines [182122] suggest periodic UDM testing duringscheduled visits truly random testing outside of sched-uled clinic visits may not be feasible in many settings(eg primary care) or appropriate for all patients [18]
Relevant Literature
The identified studies related to UDM frequency do notdifferentiate strategies for low- moderate- and high-risklevels Nevertheless clinical trials assessing the effectsof UDM on outcomes are particularly relevant to deci-sions regarding frequency of monitoring (SupplementaryTable 1) Adherence to prescribed opioids is higher withmore frequent UDM according to a retrospective analy-sis of patients with chronic pain in private practices[116] In two prospective trials at an interventional painmanagement practice adherence monitoring that in-cluded random UDM was associated with reductions inindicators of opioid misuse (determined via periodicchart review UDM pill counts and verification of infor-mation with treating clinicians and pharmacies) [24] andillicit drug use (determined via UDM) [117] In anotherstudy a comprehensive risk reduction strategy includ-ing UDM led to decreased pill confiscations by law en-forcement agents and improved primary care providersrsquoperceptions of the overall quality of pain management[118] A structured program designed to support pri-mary care providers with chronic pain management ledto a greater-than-two-fold increase in UDM 22 months
after initiation of the program which was associatedwith a 727 relative decrease in total emergency de-partment (ED) visits and a 596 relative decrease inunscheduled primary care provider visits per patient onaverage [119]
The main negative clinical consequence of UDMreported in the literature was a lower likelihood ofpatients attending a second visit at an urban academicpain clinic after urine testing was used in the first officevisit [120] Individuals with positive test results for an il-licit substance were less likely to attend the second visitthan those with a negative result [120] Although thisstudy suggests that UDM at first visit may hinderpatient-clinician trust patient response to UDM mayvary by clinical setting by how the rationale for UDM isexplained to the patient and by the degree to whichUDM becomes routine in clinical practice
Many studies showed significant benefits of UDM how-ever a few did not No association between UDM and all-cause mortality was found in VA patients [121] althoughan association was not necessarily expected in this sam-ple of patients with a high burden of comorbiditiesAnother study conducted in a large health care systemshowed that an opioid risk reduction initiative (includingrecommendations on UDM) increased use of UDM with-out affecting rates of unexpected results (eg negative forprescribed opioids or positive for cannabis) [122]
Several studies and surveys of physicians (eg pain andaddiction specialists) nurses PAs and other health careprofessionals mainly from pain practices and academiccenters have assessed the frequency of UDM during

opioid therapy for chronic pain [296580123124]which provides context for recommendations on fre-quency Patients with chronic pain received an averageof 34 UDM tests per year according to a 2007 study ina Kentucky private pain practice [80] The frequency ofUDM testing increased by an average of 34 yearlyfrom 2005 to 2008 in a clinical laboratory serving a largeacademic center [123] Surveys indicated that individualpain and addiction experts differed in their frequency ofUDM use from testing at every office visit to yearly[2965] although most preferred random testing[65124] As a caveat these surveys did not focus onprimary care settings
Expert Panel Discussion
The expert panel did not specify how the relative riskcategories should be determined aside from suggestingseveral potential risk assessment tools and strategies(see the Question 2 section) Baseline UDM testing is tobe performed either before initiation of opioid therapyor for those continuing opioid therapy from another pro-vider within three months of the first office visit If thepatient received UDM testing from another providerwithin the previous year and the results were consistentwith prescribed opioid therapy no immediate retestingmay be needed to continue therapy
Regular UDM is recommended even in low-risk patientsbecause their circumstancesbehaviors can change overthe course of therapy Patients at especially low risk(eg receiving low-dose as-needed opioids) mayrequire infrequent UDM (eg every two years) Moderate-risk patients may become higher or lower risk dependingon their environment and stressors intense monitoring isusually not required in these patients but periodic reevalu-ation of their situationsrisk factors is appropriate
High-risk patients require more frequent individualizedUDM testing than those at low or moderate risk al-though the evidence supporting the effectiveness of in-tense monitoring is weak Most primary care providerscan best care for high-risk patients by referring them toa pain and addiction specialist when available Primarycare clinicians who are trained in chronic pain manage-ment utilize UDM are experienced in interpreting UDMresults and have access to consultant toxicologists maybe able to appropriately care for high-risk patientsandor comanage them with a pain specialist Currentguidelines for UDM in patients with substance usedisorder recommend use of personalized testingregimens [28]
Additional Expert Panel Recommendations andDiscussion
UDM Rationale
Clinicians are encouraged to include information relatedto UDM in patient-provider agreements and explain to
patients that the primary goals of UDM are to improvethe safety and effectiveness of therapy by monitoringadherence Furthermore UDM is strongly recommendedas part of a universal precautions approach [125]Consistent UDM results provide objective data to sup-port decision-making during chronic opioid therapy
UDM Process
The panelists recommend that clinicians discuss theUDM process openly with patients as they do with allother clinical testing and document the time of lastmedication use before urine collection Unexpectedresults may be caused by laboratory errors (eg mislab-eling) or by sample adulteration including substitution ofsynthetic or another individualrsquos urine Signs of tamper-ing include temperature outside the normal range of90 F to 100 F within four minutes of sample collectionpH outside the normal range of 45 to 80 low creati-nine concentration (ie 20 mgdL) low specific gravity(ie 1003) presence of adulterants or detection ofparent drug without metabolites [28] Variation in metab-olite levels may also result from pharmacogenetic anom-alies or drug-drug interactions affecting drugmetabolism [28126]
Strategies to prevent sample tampering depend on theclinical setting and can include observed collection(viewed as overly invasive of a patientrsquos privacy) achain-of-custody protocol (ie documentation for han-dling of the specimen) and a truly random collection(ie a protocol to notify the patients of required testingwithin a set period) [28] Although observed urine sam-ple collection at pain clinics has been recommended[83] this practice and chain-of-custody protocols aretypically not followed Despite risk-mitigation strategiesdedicated individuals can still manipulate their UDMsamples or consume prescribed medication before of-fice visits to conceal misuse or diversion Patients withan opioid use disorder may not be able to control theirdrug use to avoid unexpected UDM results despitescheduled collection
Alcohol Screening
For patients with a substance use disorder alcohol maybe problematic and prohibited in any amount for otherpatients with chronic pain only high-risk alcohol use(eg binge drinking) is a concern Many opioids includeblack box warnings about the concurrent use of alcoholbecause of the potential for fatal overdose [127] Onereviewed guideline recommends screening for alcoholwith UDM in patients with chronic pain [22] ethyl glucu-ronide ethyl sulfate or ethanol in UDM indicates alcoholuse [128] As a caveat immunoassay and definitiveUDM may not differentiate between alcoholic beveragesand alcohol-containing medications mouthwashes andhand sanitizers [28] Instead of UDM the panelists

recommend the SISQ ldquoHow many times in the past yearhave you had (five or more drinks [men] four or moredrinks [women]) in a dayrdquo from the National Institute onAlcohol Abuse and Alcoholism [111] to identify un-healthy alcohol use as this question is simple to admin-ister and is validated [129] In primary care settings thesensitivity of the alcohol SISQ for identifying alcohol usedisorder is 88 and the specificity is 84 [130]
Cannabis Screening
Practices for cannabis screening vary [131] individualprescribers can decide whether detecting cannabis byUDM is appropriate by consulting local laws [132133]and common practice as well as by considering theadvantagesdisadvantages discussed below At the timeof this publication cannabis is federally illegal (ie clas-sified by the US Drug Enforcement Administration asSchedule 1 under the Controlled Substances Act) butseveral states have passed legislation to decriminalize itfor medical andor recreational use [131ndash134] The CDCGuideline for Prescribing Opioids for Chronic Pain indi-cates that the clinical implications of a positive UDM re-sult for cannabis are uncertain [18] the VAUSDepartment of Defense guidelines estimate the length oftime it can be detected in urine [21] and theWashington State guidelines suggest implementing anoffice policy for patients who use cannabis [22] Theseguidelines [182122] and this consensus report do notprovide formal graded recommendations for or againstUDM screening for cannabis or for interpretation of theresults
Clinicians who avoid cannabis testing may miss criticalinformation that could inform patient monitoring and im-prove safety Data from Colorado indicate increased EDvisits hospitalizations and proportions of fatal motor ve-hicle accidents related to cannabis intoxication after de-criminalization [134ndash136] Illegal use of cannabis is amarker for opioid misuse and substance use disorders[137] and a rationale to classify a patient as high riskAnother concern is that patients may divert prescriptionopioids to purchase cannabis
If clinicians choose to assess patientsrsquo nonprescriptioncannabinoid use there is a validated SISQ for drugs in-cluding cannabis (ie ldquoHow many times in the past yearhave you used an illegal drug or used a prescriptionmedication for nonmedical reasonsrdquo) [93] with a sensi-tivity of 97 and a specificity of 79 for substance usedisorders in primary care settings [130] Although somemetabolites of synthetic cannabinoids (eg spice) canbe analyzed with specialized immunoassayschromatographyspectrometry-based assays are betterfor assessing the many emerging synthetic cannabi-noids and their metabolites [138]
A subject of ongoing debate is whether co-administration of opioids and cannabis (used
recreationally or medically) is safe or reasonable for clini-cians to allow Cannabis is increasingly accepted formedical purposes especially for cancer pain syn-dromes However allowing patients with chronic pain touse cannabis is a potential liability for clinicians (includ-ing pharmacists) regardless of the drugrsquos legal status intheir state [139] The safety of cannabis for patients withchronic pain is not clearly established [140] and little isknown regarding the safety of concurrent use withopioids apart from the potential opioid-sparing effects ofcannabis [141] The composition and dose of the manyactive components in cannabis vary widely [133142]which leads to variable toxicity [143] and complicatessafety studies Cannabinoids may inhibit cytochromeP450 2D6 [144] (involved in opioid metabolism [145])and therefore affect both the efficacy of opioids and theability to detect metabolites in UDM The panelists pro-posed that a single clinician be responsible for manag-ing both opioid and cannabis use in states where thedrug has been decriminalized and the benefits of con-current use outweigh the risks
Interpreting UDM Results and Implications forChanging Clinical Practice
The panelists believe that clinicians should follow manu-facturer instructions for specific POC UDM tests and di-rect any questions about interpreting results to anexpert in toxicology or clinical pathology Laboratoriesperforming UDM have a responsibility to provide cleartest results answer questions and offer support on clin-ical decisions When clinicians are confronted with un-expected results potential causes for false-positive andfalse-negative results (eg quinolone antibiotics tolme-tin Figure 1) are important to investigate A summary ofcommunications and discussions about results with thelaboratory and other experts can be included in themedical record to document the medical necessity oftesting and related clinical decision-making
Communications with patients about the purpose andresults of UDM should be nonjudgmental and nonpuni-tive and should focus on safety and risks associatedwith misuse and opioid use disorder To avoid unex-pected results open discussion with patients is recom-mended and may include asking questions such as ldquoIfwe test you today what will we find in your urine Willthere be any surprisesrdquo Development of a plan to ad-dress UDM results that are inconsistent with therapy issuggested to mitigate safety risks for patients and po-tential regulatory board sanctions for clinicians Of noteUDM results that are consistent with prescribed opioidscannot differentiate among appropriate use occasionaluse or misuse and opioid use disorder negative UDMresults for prescribed opioids cannot distinguishbetween infrequent need for medicine overuse and run-ning out falsification of the urine sample and diversionResults of UDM are only part of the clinical information

(eg including patient history) that must be consideredbefore a treatment plan is changed
Detailed recommendations on proper opioid prescribingand appropriate changes to patient care after unex-pected UDM results are outside the scope of this con-sensus report but are discussed in other guidelines[18202240] In brief options to address unexpectedUDM results include open and nonjudgmental discus-sions with patients additional confirmation testing in-creased monitoring a switch to a nonopioid painmedication or referral for treatment of an opioid usedisorder [18202240]
Three studies from the Philadelphia VA Medical Center in-vestigated how UDM results affected provider behavior[119146147] additional research to determine how UDMresults should influence patientsrsquo therapy is warranted Inthe absence of this information a follow-up consensusmeeting to evaluate expert opinion was suggested
Conclusions
In summary the expert panel made the following rec-ommendations regarding UDM (Figure 2)
1 Use definitive UDM testing (eg with GC-MS LC-MS or LC-MSMS) as the most clinically appropriatemethod for assessing baseline opioid use and opioidmisuse in most patients with chronic pain being con-sidered for opioids as well as for ongoing monitoringof patients receiving opioids for chronic pain unlesspresumptive testing is required by institutional orpayer policies A rational approach to choosing themost relevant analytes for UDM testing is proposedand should be documented by the clinician
2 To guide UDM frequency assess and stratify patientsprescribed opioid therapy for chronic pain with thefollowing strategies
bull perform a physical examination and obtain relevantpatient history for eventsdiagnoses and behaviorsthat have been shown to predict opioid misuseand opioid use disorder (eg history of substanceuse disorders psychiatric conditions sexual abuse)including information from previous providers forpatients transferring care
bull use validated tools to assess risk for aberrantmedication-taking behavior opioid misuse opioiduse disorder and the potential for respiratory de-pressionoverdose
bull check PDMPs and previous UDM results whenavailable
3 Perform UDM at baseline in patients receiving opioidsfor chronic pain During ongoing monitoring performUDM at least annually for low-risk patients two ormore times per year for moderate-risk patients andthree or more times per year for high-risk patientsAdditional monitoring can be performed as frequently
as necessary according to clinical judgment (egworrisome patient behavior related to the prescribedmedication)
The recommendations in this consensus report are meantto provide practical advice on implementing rational UDMacross a broad range of clinical practices in a patient-centric manner Some clinicians may not have access toappropriate resources to perform routine definitive UDMor to refer patients to pain specialists alternatives are pro-vided in the expert panel discussion sections Higher-quality studies on patient outcomes with UDM areneeded As a next step a consensus recommendationinitiative similar to this one that discusses appropriate clini-cian actions in response to test results that are inconsis-tent with prescribed therapy is warranted

(ie high-value and individualized) UDM in patients re-ceiving opioids for chronic pain This report presents thefollowing information
bull discussions and views of a multidisciplinary consen-sus panel regarding recent UDM guidelines andliterature
bull best practices for UDM in patients prescribed opioidtherapy for chronic pain
bull areas for further UDM research and evaluation
These consensus recommendations are intended for abroad range of physicians and other health care profes-sionals (eg pharmacists physician assistants [PAs]nurse practitioners and certified registered nurse anes-thetists) involved in the management of patients withchronic pain
Methods
Phase 1 Prioritizing Issues of Greatest Importance toUDM on the Basis of Research Published Guidelinesand Panel Member Experiences
A diverse group of panelists from various clinical settings(eg pain medicine addiction medicine internal medi-cine primary care pharmacotherapeutics and toxicol-ogy) were recruited to serve as experts in UDM as wellas to provide a payer perspective when possible Beforethe UDM consensus panel meeting the panelists wereasked to provide topics for consensus recommendationfollowed by feedback on a preliminary list of questionson these topics the co-chairs (CEA and LRW chosenfor their in-depth experience and long-standing associa-tion with the American Academy of Pain Medicine

[AAPM]) adjudicated any discrepancies to develop the fi-nal list of questions
1 Which UDM test(s) should be used and in whichpatients prescribed opioids for chronic pain shouldthe tests be used according to a medical literaturereview clinical experience clinical chemistry of drugtesting and practical considerations
2 How should patients undergoing UDM be stratifiedfor opioid misuse risk
3 How often should UDM occur in patients with lowmedium and high risk for opioid misuse or opioiduse disorder
For background the panel members identified existingguidelines that have been most influential in UDM inchronic pain practice Articles were obtained fromPubMed using the search terms urine drug testing andchronic pain Studies published from June 13 2012 (iethe date of the previous guidelines specific to UDM [40])to April 6 2016 (the date of the search) were includedSearch results were filtered to exclude narrative reviewscase reports studies involving nonurine matrices (egblood oral fluid hair) laboratory tests and any studieswith findings not relevant to the three selected questionson UDM Studies in patients with cancer pain were ex-cluded to narrow the patient population similar to otherguidelines [18ndash20] however this should not be construedas a recommendation to not perform UDM in patientsprescribed opioids for cancer-related chronic pain To ad-dress potential literature gaps additional references (egkey landmark studies) were identified through referencelists and by panelist recommendations
Using the process followed by the Centers for DiseaseControl and Prevention (CDC) Guideline for PrescribingOpioids for Chronic Pain [1854] an abbreviated Grading ofRecommendations Assessment Development andEvaluation (GRADE) methodology was performed Studieswere evaluated and graded as type 1 through 4 which gen-erally corresponded to the following study categories [54]
1 randomized controlled trials (RCTs) or observationalstudies with overwhelming evidence
2 RCTs with important limitations or observational stud-ies with exceptionally strong evidence
3 observational studies or RCTs with notable limitations
4 clinical experience and observations observationalstudies with important limitations or RCTs with sev-eral major limitations
Phase 2 Convening Expert Panel Members forInteractive Discussions and Voting to Reach Consensus
Consensus panel meetings for UDM occurred via web-based teleconferences on August 11 and 18 2016 for
a total of five hours Section leaders (JF JAG RCPand DPA selected by co-chairs to lead discussions)reviewed the literature and led interactive discussionsabout the main questions related to UDM before con-sensus on recommendations was reached with a modi-fied nominal group technique [5556] This consensusmethod was selected because of its demonstrated va-lidity long history of use and time efficiency as well asthe ability for all panelists to provide input [57] After ev-ery panelist provided an answer to a question panelistsvoted for their preferred answer if multiple options wereproposed Additional discussion cycles and voting wereperformed until consensus was reached
Phase 3 Preparation of the Consensus Report
The content of this report reflects an extensive review ofexisting UDM research and guidelines discussion fromseveral meetings and communications among the ex-pert panelists and consensus recommendationsPanelists reviewed and revised content in multiplestages of manuscript development before finalization
Results
Six recent guidelines that address UDM in patients withchronic pain were identified by panelists as most rele-vant to the three key questions The literature searchfound 85 studies pertaining to UDM 21 additional refer-ences were added to address gaps in the existing litera-ture on topics requested by panelists After filtering forrelevance to the three main questions (performed by aneditorial service directed by the authors) 41 referencesfrom the expanded literature search were included all ofwhich were graded for scientific merit as type 3 (lowquality) or 4 (lowest quality) by the authors Validationstudies even when well designed were not consideredequivalent to RCTs and were rated as lower quality

assessing baseline opioid use and opioid misuse in al-most all patients with chronic pain being considered foropioids as well as for ongoing monitoring of patients re-ceiving opioids for chronic pain unless presumptivetesting is required by institutional or payer policies A ra-tional approach to choosing the most relevant analytes(ie substances to be tested) for UDM testing is pro-posed (in the Expert Panel Discussion section for ques-tion 1) and should be documented by the clinician
Existing Guidelines
In contrast to this expert panelrsquos recommendation pre-viously published guidelines suggest that patientsundergo presumptive testing with immunoassay whenthey are prescribed opioids for chronic pain[18202240] some guidelines specify that the testshould be POC [2040] Confirmatory definitive tests aregenerally reserved for resolving unexpected results fromimmunoassays [18202240] or for detecting specificopioids that cannot be identified with standard immu-noassays [18] According to the CDC [18] CMS [58]and other payer policies [5059] definitive testing is ap-propriate only when it affects clinical decision-makingand patient management The Washington State guide-lines suggest considering the following drugs for aUDM panel in addition to medications prescribed alco-hol amphetamines barbiturates benzodiazepinescannabinoids cocaine fentanyl methadone opiatesand oxycodone [22]
Relevant Literature
Surveys indicate that UDM in patients prescribedopioids for chronic pain varies widely (ie 19ndash636of patients receive UDM at some point during treatment[60ndash63] and 69ndash100 of clinicians administer UDM[295263ndash66]) which demonstrates a need for guid-ance Traditionally POC immunoassays have been usedfor initial screening in UDM because they provide rapidresults at relatively low cost [28] However false-positiveresults (eg 22 for opiate immunoassays [32]) can becaused by cross-reactivity [28] and false-negativeresults (eg 30 for opiate assays [32]) may occur be-cause of drug concentration cutoffs and cross-reactivityin particular among drugs in similar chemical classes[67] Some opioids and benzodiazepines are not welldetected by immunoassays [67]
Compared with immunoassays definitive testing candetect a greater number of compounds (eg variousbenzodiazepines [67ndash69]) and demonstrates higher sen-sitivity and specificity [70] The gold standard of defini-tive testing was considered to be GC-MS [71] but LC-MSMS has become a favored method [28] because itis associated with less drug interference and can beperformed with smaller urine volumes than for GC-MS[71] Validation of two new LC-MSMS methods wasidentified through our literature search [7273] As a ca-veat detection of metabolites of some prescriptionopioids (eg buprenorphine by certain routes ofadministration) or illicit substances (eg heroin) with

LC-MSMS is challenging in part because of insufficientsensitivity of tests and individual variation in drug metab-olism [7475]
Although (confirmatory) definitive testing is often used toverify unexpected immunoassay results recent evidencesuggests that it is more accurate than immunoassay atassessing patientsrsquo substance use at initial screening[76ndash78] A hybrid UDM approach in which each drugwas measured with either immunoassay or LC-MS(depending on which platform has better accuracy andspeed for each drug) reduced the need for confirmationtesting and time to results [79] In a study at a privatepain practice clinicians and patients discussed unex-pected results from initial immunoassay UDM and opennonjudgmental communication was emphasized thisapproach led to only 3 to 5 of cases requiring con-firmatory GC-MS testing [80] The clinical utility of a hy-brid immunoassayLC-MS approach and of effectivepatient communication to prevent the need for confir-matory GC-MS testing will need to be furtherestablished
Expert Panel Discussion
The panelists expressed concerns about limited sensitiv-ity and specificity as well as misinterpretation errors withclass-specific immunoassays especially in the primarycare setting The initial low cost of immunoassays maybe negated by their potential inaccuracy which can in-crease the downstream financial burden to confirm con-flicting or unexpected results and potentially increasecosts for additional treatments and office visits when apatient is inappropriately continued or discontinued fromopioids because of misinterpretation of results Definitivetesting although often more expensive than immunoas-say initially includes a more comprehensive panel ofsubstances and is more sensitive and specific fordetecting adherence to prescribed opioids and use ofother substances For these reasons several panelistsconsider definitive testing to be the most rational choicefor UDM and elect to use it exclusively for both prelimi-nary testing and follow-up testing when results are con-tested by the patient
The expert panel recognizes that not all clinicians havereliable access to definitive testing laboratories andsome payers reimburse for definitive testing only afteran immunoassay result is inconsistent with therapy Therecommendations in this consensus are intended to beconsidered together with practical clinical and payerconcerns When required by payers and institutionsimmunoassays may be sufficient for monitoring low-riskpatients particularly when clinicians and patients en-gage in open communication
Given the potentially high cost of definitive testing ratio-nal selection of analytes is recommended Appropriatesubstances to analyze for UDM include all controlled
substances (and selected noncontrolled coanalgesicssuch as antidepressants and anticonvulsants) that a pa-tient is prescribed as well as substances unexpectedlyfound at previous UDM Inclusion of additional medica-tions andor alcohol is driven by their potential for harm(ie risk-relevant testing) For identification of substan-ces most likely to be used and diverted consult recentnational survey results [81] and relevant geographic data[82] Greater numbers of analytes will likely need to betested for patients at higher risk for substance usedisorders
Complexities regarding UDM test properties necessitatethat clinicians have access to an expert (eg toxicolo-gist knowledgeable pain or addiction specialist pathol-ogist) when choosing the most appropriate test andinterpreting unexpected results Clinicians should alsobe aware of relevant state mandates regulations andguidelines [83] descriptions of UDM requirements bystate are available from state medical boards and theAAPM website (httpwwwpainmedorgadvocacystate-updates)
Question 2 How Should Patients Undergoing UDMBe Stratified for Opioid Misuse Risk
Expert Panel Recommendations
To guide UDM frequency assess and stratify patientswho are prescribed opioid therapy for chronic pain withthe following strategies
bull Perform a physical examination and obtain relevantpatient history for eventsdiagnoses and behaviorsthat have been shown to predict opioid misuse andopioid use disorder (eg history of substance use dis-orders psychiatric conditions sexual abuse) includinginformation from previous providers for patients trans-ferring care
bull Use validated tools to assess the risk for aberrantmedication-taking behavior opioid misuse opioid usedisorder and the potential for respiratory depressionoverdose
bull Check prescription drug monitoring programs(PDMPs) and previous UDM results when available
Existing Guidelines
Some guidelines [182022] recommend the use of riskassessment tools to stratify patients receiving opioidsthe Opioid Risk Tool (ORT) and Screener and OpioidAssessment for Patients with PainndashRevised (SOAPPVR -R)are frequently mentioned in other guidelines[18224084] Tools deemed most relevant by panelistson the basis of validation studies and use in practiceare described in Table 2 [18192284ndash94] There is aneed for further clinical validation of existing tools [19]and for development of newer and more accurate toolsthat incorporate additional risk factors [1895] Risk tools

are just one part of a comprehensive patient evaluation[2040]
Relevant Literature
Several tools for predicting and determining current risk ofaberrant medication-taking behaviors (eg lost prescrip-tion request for early refill) opioid misuse and opioid usedisorder are reported in the literature [96ndash99] In a painclinicndashbased study a semistructured clinical interview byan addiction psychologist was more sensitive than theORT Pain Medication Questionnaire and SOAPP-R atpredicting aberrant drug-related behavior [98] TheSOAPP-R showed the highest sensitivity of these self-report measures but may overestimate risk [98]
The use of external information (eg PDMPs) can alsoimprove patient management [100] In a university-based multidisciplinary pain management center misuseand diversion were detected more frequently by addingUDM andor a PDMP check to a baseline strategy ofcomparing patient reports and review of medicalrecords [101] However a systematic review of primarycare pain clinic and Veterans Administration (VA)Medical Center settings concluded that no single proce-dure or set of variables was sufficient to identify patientswith chronic pain who are at risk for opioid misuse orharmful substance use [97]
Expert Panel Discussion
The expert panelists suggest that patients be assessedfor risk of aberrant medication-taking behavior misuseand opioid use disorder to determine the frequency ofUDM A high-dose cutoff alone (eg 120-mg morphineequivalent dose per day [22]) was perceived as being in-adequate for identifying high-risk patients because highdoses may be appropriate to accommodate develop-ment of tolerance in specific patients [192187] In addi-tion patients predisposed to misuse may be at risk ofopioid use disorder or unsafe use even with low tomoderate doses
No specific risk assessment tool or behavioral assess-ment is recommended by panelists Clinicians are en-couraged to choose one or more of the many availabletools that match their preferences and can be incorpo-rated into their electronic medical records and workflow Understanding why specific factors predict risk ismore important than knowledge of the risk assessmenttools themselves (Figure 3 [1997102ndash107]) Risk strati-fication is not static and regular reevaluation of patientcircumstances (eg loss of a job divorce) is recom-mended An unexpected UDM result increases apatientrsquos risk of misuse and opioid use disorder neces-sitates more frequent testing and prompts reconsidera-tion of whether to modify opioid therapy or refer thepatient to a pain or addiction specialist
A comprehensive evaluation to assess the presence orrisk of misuse and opioid use disorder includes ques-tions about patientsrsquo history of substance use disordersand current clinical characteristics (eg from a physicalexamination) input from patientsrsquo family members andother health care providers (eg psychiatrists previouspain specialists) and pill counts Behaviors that may in-dicate increased likelihood of misuse or opioid use dis-order include requests for early refills [108]unauthorized dose escalations [109] and use of anotherindividualrsquos medication [109] Substance use disorder isgenerally associated with one or more of the four ldquoCsrdquo(ie impaired Control over use Compulsive useContinued use despite harm and Craving) [110]
A few simple questions (eg single-item screeningquestions [SISQs] for alcohol and drug use [93111]) fol-lowed by a discussion with patients is an efficient wayfor clinicians to incorporate risk assessment into theirpractice Reviewing a patientrsquos history of controlled sub-stance prescriptions in the PDMP is another method forassessing potential opioid misuse or substance use dis-order Clinicians should be aware of their statersquos regula-tions recommendations and resources regardingPDMPs [112] All states have or are planning to imple-ment a PDMP but reporting times vary and not everyprovider is required to participate in PDMPs in all states[112ndash114] The Comprehensive Addiction and RecoveryAct of 2016 is intended to improve the efficiency ofthese programs to track prescription drug use and helpprevent inappropriate use [115] Despite their inconsis-tencies PDMPs (when available) have become standardof care as part of patient risk evaluation WhetherPDMP data will predict aberrant behaviors or other ad-verse outcomes is not yet known and represents a gapin the science and an unmet need
Question 3 How Often Should UDM Occur in Patientswith Low Medium and High Risk for Opioid Misuseor Opioid Use Disorder
Expert Panel Recommendation
Perform UDM at baseline in patients prescribed opioidsfor chronic pain During ongoing monitoring performUDM at least annually for low-risk patients two or moretimes per year for moderate-risk patients and three ormore times per year for high-risk patients Additionalmonitoring can be performed at any risk level as fre-quently as necessary according to clinical judgment
Existing Guidelines
Recent guidelines recommend UDM at least annually forall patients regardless of risk [18] every six months totwo years for patients at low risk for opioid misuse oropioid use disorder [202240] one to three times peryear for moderate-risk patients [2022] and at least twoto four times per year for high-risk patients [202240]

The CDC Guideline for Prescribing Opioids for ChronicPain does not recommend tailoring the monitoringschedule according to risk because tools that predictharmful use lack sufficient accuracy [18] Several guide-lines [182122] suggest periodic UDM testing duringscheduled visits truly random testing outside of sched-uled clinic visits may not be feasible in many settings(eg primary care) or appropriate for all patients [18]
Relevant Literature
The identified studies related to UDM frequency do notdifferentiate strategies for low- moderate- and high-risklevels Nevertheless clinical trials assessing the effectsof UDM on outcomes are particularly relevant to deci-sions regarding frequency of monitoring (SupplementaryTable 1) Adherence to prescribed opioids is higher withmore frequent UDM according to a retrospective analy-sis of patients with chronic pain in private practices[116] In two prospective trials at an interventional painmanagement practice adherence monitoring that in-cluded random UDM was associated with reductions inindicators of opioid misuse (determined via periodicchart review UDM pill counts and verification of infor-mation with treating clinicians and pharmacies) [24] andillicit drug use (determined via UDM) [117] In anotherstudy a comprehensive risk reduction strategy includ-ing UDM led to decreased pill confiscations by law en-forcement agents and improved primary care providersrsquoperceptions of the overall quality of pain management[118] A structured program designed to support pri-mary care providers with chronic pain management ledto a greater-than-two-fold increase in UDM 22 months
after initiation of the program which was associatedwith a 727 relative decrease in total emergency de-partment (ED) visits and a 596 relative decrease inunscheduled primary care provider visits per patient onaverage [119]
The main negative clinical consequence of UDMreported in the literature was a lower likelihood ofpatients attending a second visit at an urban academicpain clinic after urine testing was used in the first officevisit [120] Individuals with positive test results for an il-licit substance were less likely to attend the second visitthan those with a negative result [120] Although thisstudy suggests that UDM at first visit may hinderpatient-clinician trust patient response to UDM mayvary by clinical setting by how the rationale for UDM isexplained to the patient and by the degree to whichUDM becomes routine in clinical practice
Many studies showed significant benefits of UDM how-ever a few did not No association between UDM and all-cause mortality was found in VA patients [121] althoughan association was not necessarily expected in this sam-ple of patients with a high burden of comorbiditiesAnother study conducted in a large health care systemshowed that an opioid risk reduction initiative (includingrecommendations on UDM) increased use of UDM with-out affecting rates of unexpected results (eg negative forprescribed opioids or positive for cannabis) [122]
Several studies and surveys of physicians (eg pain andaddiction specialists) nurses PAs and other health careprofessionals mainly from pain practices and academiccenters have assessed the frequency of UDM during

The expert panel did not specify how the relative riskcategories should be determined aside from suggestingseveral potential risk assessment tools and strategies(see the Question 2 section) Baseline UDM testing is tobe performed either before initiation of opioid therapyor for those continuing opioid therapy from another pro-vider within three months of the first office visit If thepatient received UDM testing from another providerwithin the previous year and the results were consistentwith prescribed opioid therapy no immediate retestingmay be needed to continue therapy
Regular UDM is recommended even in low-risk patientsbecause their circumstancesbehaviors can change overthe course of therapy Patients at especially low risk(eg receiving low-dose as-needed opioids) mayrequire infrequent UDM (eg every two years) Moderate-risk patients may become higher or lower risk dependingon their environment and stressors intense monitoring isusually not required in these patients but periodic reevalu-ation of their situationsrisk factors is appropriate
High-risk patients require more frequent individualizedUDM testing than those at low or moderate risk al-though the evidence supporting the effectiveness of in-tense monitoring is weak Most primary care providerscan best care for high-risk patients by referring them toa pain and addiction specialist when available Primarycare clinicians who are trained in chronic pain manage-ment utilize UDM are experienced in interpreting UDMresults and have access to consultant toxicologists maybe able to appropriately care for high-risk patientsandor comanage them with a pain specialist Currentguidelines for UDM in patients with substance usedisorder recommend use of personalized testingregimens [28]
Additional Expert Panel Recommendations andDiscussion
UDM Rationale
Clinicians are encouraged to include information relatedto UDM in patient-provider agreements and explain to
patients that the primary goals of UDM are to improvethe safety and effectiveness of therapy by monitoringadherence Furthermore UDM is strongly recommendedas part of a universal precautions approach [125]Consistent UDM results provide objective data to sup-port decision-making during chronic opioid therapy
UDM Process
The panelists recommend that clinicians discuss theUDM process openly with patients as they do with allother clinical testing and document the time of lastmedication use before urine collection Unexpectedresults may be caused by laboratory errors (eg mislab-eling) or by sample adulteration including substitution ofsynthetic or another individualrsquos urine Signs of tamper-ing include temperature outside the normal range of90 F to 100 F within four minutes of sample collectionpH outside the normal range of 45 to 80 low creati-nine concentration (ie 20 mgdL) low specific gravity(ie 1003) presence of adulterants or detection ofparent drug without metabolites [28] Variation in metab-olite levels may also result from pharmacogenetic anom-alies or drug-drug interactions affecting drugmetabolism [28126]
Strategies to prevent sample tampering depend on theclinical setting and can include observed collection(viewed as overly invasive of a patientrsquos privacy) achain-of-custody protocol (ie documentation for han-dling of the specimen) and a truly random collection(ie a protocol to notify the patients of required testingwithin a set period) [28] Although observed urine sam-ple collection at pain clinics has been recommended[83] this practice and chain-of-custody protocols aretypically not followed Despite risk-mitigation strategiesdedicated individuals can still manipulate their UDMsamples or consume prescribed medication before of-fice visits to conceal misuse or diversion Patients withan opioid use disorder may not be able to control theirdrug use to avoid unexpected UDM results despitescheduled collection
Alcohol Screening
For patients with a substance use disorder alcohol maybe problematic and prohibited in any amount for otherpatients with chronic pain only high-risk alcohol use(eg binge drinking) is a concern Many opioids includeblack box warnings about the concurrent use of alcoholbecause of the potential for fatal overdose [127] Onereviewed guideline recommends screening for alcoholwith UDM in patients with chronic pain [22] ethyl glucu-ronide ethyl sulfate or ethanol in UDM indicates alcoholuse [128] As a caveat immunoassay and definitiveUDM may not differentiate between alcoholic beveragesand alcohol-containing medications mouthwashes andhand sanitizers [28] Instead of UDM the panelists

recommend the SISQ ldquoHow many times in the past yearhave you had (five or more drinks [men] four or moredrinks [women]) in a dayrdquo from the National Institute onAlcohol Abuse and Alcoholism [111] to identify un-healthy alcohol use as this question is simple to admin-ister and is validated [129] In primary care settings thesensitivity of the alcohol SISQ for identifying alcohol usedisorder is 88 and the specificity is 84 [130]
Cannabis Screening
Practices for cannabis screening vary [131] individualprescribers can decide whether detecting cannabis byUDM is appropriate by consulting local laws [132133]and common practice as well as by considering theadvantagesdisadvantages discussed below At the timeof this publication cannabis is federally illegal (ie clas-sified by the US Drug Enforcement Administration asSchedule 1 under the Controlled Substances Act) butseveral states have passed legislation to decriminalize itfor medical andor recreational use [131ndash134] The CDCGuideline for Prescribing Opioids for Chronic Pain indi-cates that the clinical implications of a positive UDM re-sult for cannabis are uncertain [18] the VAUSDepartment of Defense guidelines estimate the length oftime it can be detected in urine [21] and theWashington State guidelines suggest implementing anoffice policy for patients who use cannabis [22] Theseguidelines [182122] and this consensus report do notprovide formal graded recommendations for or againstUDM screening for cannabis or for interpretation of theresults
Clinicians who avoid cannabis testing may miss criticalinformation that could inform patient monitoring and im-prove safety Data from Colorado indicate increased EDvisits hospitalizations and proportions of fatal motor ve-hicle accidents related to cannabis intoxication after de-criminalization [134ndash136] Illegal use of cannabis is amarker for opioid misuse and substance use disorders[137] and a rationale to classify a patient as high riskAnother concern is that patients may divert prescriptionopioids to purchase cannabis
If clinicians choose to assess patientsrsquo nonprescriptioncannabinoid use there is a validated SISQ for drugs in-cluding cannabis (ie ldquoHow many times in the past yearhave you used an illegal drug or used a prescriptionmedication for nonmedical reasonsrdquo) [93] with a sensi-tivity of 97 and a specificity of 79 for substance usedisorders in primary care settings [130] Although somemetabolites of synthetic cannabinoids (eg spice) canbe analyzed with specialized immunoassayschromatographyspectrometry-based assays are betterfor assessing the many emerging synthetic cannabi-noids and their metabolites [138]
A subject of ongoing debate is whether co-administration of opioids and cannabis (used
recreationally or medically) is safe or reasonable for clini-cians to allow Cannabis is increasingly accepted formedical purposes especially for cancer pain syn-dromes However allowing patients with chronic pain touse cannabis is a potential liability for clinicians (includ-ing pharmacists) regardless of the drugrsquos legal status intheir state [139] The safety of cannabis for patients withchronic pain is not clearly established [140] and little isknown regarding the safety of concurrent use withopioids apart from the potential opioid-sparing effects ofcannabis [141] The composition and dose of the manyactive components in cannabis vary widely [133142]which leads to variable toxicity [143] and complicatessafety studies Cannabinoids may inhibit cytochromeP450 2D6 [144] (involved in opioid metabolism [145])and therefore affect both the efficacy of opioids and theability to detect metabolites in UDM The panelists pro-posed that a single clinician be responsible for manag-ing both opioid and cannabis use in states where thedrug has been decriminalized and the benefits of con-current use outweigh the risks
Interpreting UDM Results and Implications forChanging Clinical Practice
The panelists believe that clinicians should follow manu-facturer instructions for specific POC UDM tests and di-rect any questions about interpreting results to anexpert in toxicology or clinical pathology Laboratoriesperforming UDM have a responsibility to provide cleartest results answer questions and offer support on clin-ical decisions When clinicians are confronted with un-expected results potential causes for false-positive andfalse-negative results (eg quinolone antibiotics tolme-tin Figure 1) are important to investigate A summary ofcommunications and discussions about results with thelaboratory and other experts can be included in themedical record to document the medical necessity oftesting and related clinical decision-making
Communications with patients about the purpose andresults of UDM should be nonjudgmental and nonpuni-tive and should focus on safety and risks associatedwith misuse and opioid use disorder To avoid unex-pected results open discussion with patients is recom-mended and may include asking questions such as ldquoIfwe test you today what will we find in your urine Willthere be any surprisesrdquo Development of a plan to ad-dress UDM results that are inconsistent with therapy issuggested to mitigate safety risks for patients and po-tential regulatory board sanctions for clinicians Of noteUDM results that are consistent with prescribed opioidscannot differentiate among appropriate use occasionaluse or misuse and opioid use disorder negative UDMresults for prescribed opioids cannot distinguishbetween infrequent need for medicine overuse and run-ning out falsification of the urine sample and diversionResults of UDM are only part of the clinical information

(eg including patient history) that must be consideredbefore a treatment plan is changed
Detailed recommendations on proper opioid prescribingand appropriate changes to patient care after unex-pected UDM results are outside the scope of this con-sensus report but are discussed in other guidelines[18202240] In brief options to address unexpectedUDM results include open and nonjudgmental discus-sions with patients additional confirmation testing in-creased monitoring a switch to a nonopioid painmedication or referral for treatment of an opioid usedisorder [18202240]
Three studies from the Philadelphia VA Medical Center in-vestigated how UDM results affected provider behavior[119146147] additional research to determine how UDMresults should influence patientsrsquo therapy is warranted Inthe absence of this information a follow-up consensusmeeting to evaluate expert opinion was suggested
Conclusions
In summary the expert panel made the following rec-ommendations regarding UDM (Figure 2)
1 Use definitive UDM testing (eg with GC-MS LC-MS or LC-MSMS) as the most clinically appropriatemethod for assessing baseline opioid use and opioidmisuse in most patients with chronic pain being con-sidered for opioids as well as for ongoing monitoringof patients receiving opioids for chronic pain unlesspresumptive testing is required by institutional orpayer policies A rational approach to choosing themost relevant analytes for UDM testing is proposedand should be documented by the clinician
2 To guide UDM frequency assess and stratify patientsprescribed opioid therapy for chronic pain with thefollowing strategies
bull perform a physical examination and obtain relevantpatient history for eventsdiagnoses and behaviorsthat have been shown to predict opioid misuseand opioid use disorder (eg history of substanceuse disorders psychiatric conditions sexual abuse)including information from previous providers forpatients transferring care
bull use validated tools to assess risk for aberrantmedication-taking behavior opioid misuse opioiduse disorder and the potential for respiratory de-pressionoverdose
bull check PDMPs and previous UDM results whenavailable
3 Perform UDM at baseline in patients receiving opioidsfor chronic pain During ongoing monitoring performUDM at least annually for low-risk patients two ormore times per year for moderate-risk patients andthree or more times per year for high-risk patientsAdditional monitoring can be performed as frequently
as necessary according to clinical judgment (egworrisome patient behavior related to the prescribedmedication)
The recommendations in this consensus report are meantto provide practical advice on implementing rational UDMacross a broad range of clinical practices in a patient-centric manner Some clinicians may not have access toappropriate resources to perform routine definitive UDMor to refer patients to pain specialists alternatives are pro-vided in the expert panel discussion sections Higher-quality studies on patient outcomes with UDM areneeded As a next step a consensus recommendationinitiative similar to this one that discusses appropriate clini-cian actions in response to test results that are inconsis-tent with prescribed therapy is warranted

[AAPM]) adjudicated any discrepancies to develop the fi-nal list of questions
1 Which UDM test(s) should be used and in whichpatients prescribed opioids for chronic pain shouldthe tests be used according to a medical literaturereview clinical experience clinical chemistry of drugtesting and practical considerations
2 How should patients undergoing UDM be stratifiedfor opioid misuse risk
3 How often should UDM occur in patients with lowmedium and high risk for opioid misuse or opioiduse disorder
For background the panel members identified existingguidelines that have been most influential in UDM inchronic pain practice Articles were obtained fromPubMed using the search terms urine drug testing andchronic pain Studies published from June 13 2012 (iethe date of the previous guidelines specific to UDM [40])to April 6 2016 (the date of the search) were includedSearch results were filtered to exclude narrative reviewscase reports studies involving nonurine matrices (egblood oral fluid hair) laboratory tests and any studieswith findings not relevant to the three selected questionson UDM Studies in patients with cancer pain were ex-cluded to narrow the patient population similar to otherguidelines [18ndash20] however this should not be construedas a recommendation to not perform UDM in patientsprescribed opioids for cancer-related chronic pain To ad-dress potential literature gaps additional references (egkey landmark studies) were identified through referencelists and by panelist recommendations
Using the process followed by the Centers for DiseaseControl and Prevention (CDC) Guideline for PrescribingOpioids for Chronic Pain [1854] an abbreviated Grading ofRecommendations Assessment Development andEvaluation (GRADE) methodology was performed Studieswere evaluated and graded as type 1 through 4 which gen-erally corresponded to the following study categories [54]
1 randomized controlled trials (RCTs) or observationalstudies with overwhelming evidence
2 RCTs with important limitations or observational stud-ies with exceptionally strong evidence
3 observational studies or RCTs with notable limitations
4 clinical experience and observations observationalstudies with important limitations or RCTs with sev-eral major limitations
Phase 2 Convening Expert Panel Members forInteractive Discussions and Voting to Reach Consensus
Consensus panel meetings for UDM occurred via web-based teleconferences on August 11 and 18 2016 for
a total of five hours Section leaders (JF JAG RCPand DPA selected by co-chairs to lead discussions)reviewed the literature and led interactive discussionsabout the main questions related to UDM before con-sensus on recommendations was reached with a modi-fied nominal group technique [5556] This consensusmethod was selected because of its demonstrated va-lidity long history of use and time efficiency as well asthe ability for all panelists to provide input [57] After ev-ery panelist provided an answer to a question panelistsvoted for their preferred answer if multiple options wereproposed Additional discussion cycles and voting wereperformed until consensus was reached
Phase 3 Preparation of the Consensus Report
The content of this report reflects an extensive review ofexisting UDM research and guidelines discussion fromseveral meetings and communications among the ex-pert panelists and consensus recommendationsPanelists reviewed and revised content in multiplestages of manuscript development before finalization
Results
Six recent guidelines that address UDM in patients withchronic pain were identified by panelists as most rele-vant to the three key questions The literature searchfound 85 studies pertaining to UDM 21 additional refer-ences were added to address gaps in the existing litera-ture on topics requested by panelists After filtering forrelevance to the three main questions (performed by aneditorial service directed by the authors) 41 referencesfrom the expanded literature search were included all ofwhich were graded for scientific merit as type 3 (lowquality) or 4 (lowest quality) by the authors Validationstudies even when well designed were not consideredequivalent to RCTs and were rated as lower quality
All graded references are included in the RelevantLiterature sections for each question Because of thelack of high-quality evidence addressing the priorityissues for this report recommendations were notassigned a strength category Recommendations(Figure 2) should be considered consensus opinionsbased on evolving evidence

assessing baseline opioid use and opioid misuse in al-most all patients with chronic pain being considered foropioids as well as for ongoing monitoring of patients re-ceiving opioids for chronic pain unless presumptivetesting is required by institutional or payer policies A ra-tional approach to choosing the most relevant analytes(ie substances to be tested) for UDM testing is pro-posed (in the Expert Panel Discussion section for ques-tion 1) and should be documented by the clinician
Existing Guidelines
In contrast to this expert panelrsquos recommendation pre-viously published guidelines suggest that patientsundergo presumptive testing with immunoassay whenthey are prescribed opioids for chronic pain[18202240] some guidelines specify that the testshould be POC [2040] Confirmatory definitive tests aregenerally reserved for resolving unexpected results fromimmunoassays [18202240] or for detecting specificopioids that cannot be identified with standard immu-noassays [18] According to the CDC [18] CMS [58]and other payer policies [5059] definitive testing is ap-propriate only when it affects clinical decision-makingand patient management The Washington State guide-lines suggest considering the following drugs for aUDM panel in addition to medications prescribed alco-hol amphetamines barbiturates benzodiazepinescannabinoids cocaine fentanyl methadone opiatesand oxycodone [22]
Relevant Literature
Surveys indicate that UDM in patients prescribedopioids for chronic pain varies widely (ie 19ndash636of patients receive UDM at some point during treatment[60ndash63] and 69ndash100 of clinicians administer UDM[295263ndash66]) which demonstrates a need for guid-ance Traditionally POC immunoassays have been usedfor initial screening in UDM because they provide rapidresults at relatively low cost [28] However false-positiveresults (eg 22 for opiate immunoassays [32]) can becaused by cross-reactivity [28] and false-negativeresults (eg 30 for opiate assays [32]) may occur be-cause of drug concentration cutoffs and cross-reactivityin particular among drugs in similar chemical classes[67] Some opioids and benzodiazepines are not welldetected by immunoassays [67]
Compared with immunoassays definitive testing candetect a greater number of compounds (eg variousbenzodiazepines [67ndash69]) and demonstrates higher sen-sitivity and specificity [70] The gold standard of defini-tive testing was considered to be GC-MS [71] but LC-MSMS has become a favored method [28] because itis associated with less drug interference and can beperformed with smaller urine volumes than for GC-MS[71] Validation of two new LC-MSMS methods wasidentified through our literature search [7273] As a ca-veat detection of metabolites of some prescriptionopioids (eg buprenorphine by certain routes ofadministration) or illicit substances (eg heroin) with

LC-MSMS is challenging in part because of insufficientsensitivity of tests and individual variation in drug metab-olism [7475]
Although (confirmatory) definitive testing is often used toverify unexpected immunoassay results recent evidencesuggests that it is more accurate than immunoassay atassessing patientsrsquo substance use at initial screening[76ndash78] A hybrid UDM approach in which each drugwas measured with either immunoassay or LC-MS(depending on which platform has better accuracy andspeed for each drug) reduced the need for confirmationtesting and time to results [79] In a study at a privatepain practice clinicians and patients discussed unex-pected results from initial immunoassay UDM and opennonjudgmental communication was emphasized thisapproach led to only 3 to 5 of cases requiring con-firmatory GC-MS testing [80] The clinical utility of a hy-brid immunoassayLC-MS approach and of effectivepatient communication to prevent the need for confir-matory GC-MS testing will need to be furtherestablished
Expert Panel Discussion
The panelists expressed concerns about limited sensitiv-ity and specificity as well as misinterpretation errors withclass-specific immunoassays especially in the primarycare setting The initial low cost of immunoassays maybe negated by their potential inaccuracy which can in-crease the downstream financial burden to confirm con-flicting or unexpected results and potentially increasecosts for additional treatments and office visits when apatient is inappropriately continued or discontinued fromopioids because of misinterpretation of results Definitivetesting although often more expensive than immunoas-say initially includes a more comprehensive panel ofsubstances and is more sensitive and specific fordetecting adherence to prescribed opioids and use ofother substances For these reasons several panelistsconsider definitive testing to be the most rational choicefor UDM and elect to use it exclusively for both prelimi-nary testing and follow-up testing when results are con-tested by the patient
The expert panel recognizes that not all clinicians havereliable access to definitive testing laboratories andsome payers reimburse for definitive testing only afteran immunoassay result is inconsistent with therapy Therecommendations in this consensus are intended to beconsidered together with practical clinical and payerconcerns When required by payers and institutionsimmunoassays may be sufficient for monitoring low-riskpatients particularly when clinicians and patients en-gage in open communication
Given the potentially high cost of definitive testing ratio-nal selection of analytes is recommended Appropriatesubstances to analyze for UDM include all controlled
substances (and selected noncontrolled coanalgesicssuch as antidepressants and anticonvulsants) that a pa-tient is prescribed as well as substances unexpectedlyfound at previous UDM Inclusion of additional medica-tions andor alcohol is driven by their potential for harm(ie risk-relevant testing) For identification of substan-ces most likely to be used and diverted consult recentnational survey results [81] and relevant geographic data[82] Greater numbers of analytes will likely need to betested for patients at higher risk for substance usedisorders
Complexities regarding UDM test properties necessitatethat clinicians have access to an expert (eg toxicolo-gist knowledgeable pain or addiction specialist pathol-ogist) when choosing the most appropriate test andinterpreting unexpected results Clinicians should alsobe aware of relevant state mandates regulations andguidelines [83] descriptions of UDM requirements bystate are available from state medical boards and theAAPM website (httpwwwpainmedorgadvocacystate-updates)
Question 2 How Should Patients Undergoing UDMBe Stratified for Opioid Misuse Risk
Expert Panel Recommendations
To guide UDM frequency assess and stratify patientswho are prescribed opioid therapy for chronic pain withthe following strategies
bull Perform a physical examination and obtain relevantpatient history for eventsdiagnoses and behaviorsthat have been shown to predict opioid misuse andopioid use disorder (eg history of substance use dis-orders psychiatric conditions sexual abuse) includinginformation from previous providers for patients trans-ferring care
bull Use validated tools to assess the risk for aberrantmedication-taking behavior opioid misuse opioid usedisorder and the potential for respiratory depressionoverdose
bull Check prescription drug monitoring programs(PDMPs) and previous UDM results when available
Existing Guidelines
Some guidelines [182022] recommend the use of riskassessment tools to stratify patients receiving opioidsthe Opioid Risk Tool (ORT) and Screener and OpioidAssessment for Patients with PainndashRevised (SOAPPVR -R)are frequently mentioned in other guidelines[18224084] Tools deemed most relevant by panelistson the basis of validation studies and use in practiceare described in Table 2 [18192284ndash94] There is aneed for further clinical validation of existing tools [19]and for development of newer and more accurate toolsthat incorporate additional risk factors [1895] Risk tools

are just one part of a comprehensive patient evaluation[2040]
Relevant Literature
Several tools for predicting and determining current risk ofaberrant medication-taking behaviors (eg lost prescrip-tion request for early refill) opioid misuse and opioid usedisorder are reported in the literature [96ndash99] In a painclinicndashbased study a semistructured clinical interview byan addiction psychologist was more sensitive than theORT Pain Medication Questionnaire and SOAPP-R atpredicting aberrant drug-related behavior [98] TheSOAPP-R showed the highest sensitivity of these self-report measures but may overestimate risk [98]
The use of external information (eg PDMPs) can alsoimprove patient management [100] In a university-based multidisciplinary pain management center misuseand diversion were detected more frequently by addingUDM andor a PDMP check to a baseline strategy ofcomparing patient reports and review of medicalrecords [101] However a systematic review of primarycare pain clinic and Veterans Administration (VA)Medical Center settings concluded that no single proce-dure or set of variables was sufficient to identify patientswith chronic pain who are at risk for opioid misuse orharmful substance use [97]
Expert Panel Discussion
The expert panelists suggest that patients be assessedfor risk of aberrant medication-taking behavior misuseand opioid use disorder to determine the frequency ofUDM A high-dose cutoff alone (eg 120-mg morphineequivalent dose per day [22]) was perceived as being in-adequate for identifying high-risk patients because highdoses may be appropriate to accommodate develop-ment of tolerance in specific patients [192187] In addi-tion patients predisposed to misuse may be at risk ofopioid use disorder or unsafe use even with low tomoderate doses
No specific risk assessment tool or behavioral assess-ment is recommended by panelists Clinicians are en-couraged to choose one or more of the many availabletools that match their preferences and can be incorpo-rated into their electronic medical records and workflow Understanding why specific factors predict risk ismore important than knowledge of the risk assessmenttools themselves (Figure 3 [1997102ndash107]) Risk strati-fication is not static and regular reevaluation of patientcircumstances (eg loss of a job divorce) is recom-mended An unexpected UDM result increases apatientrsquos risk of misuse and opioid use disorder neces-sitates more frequent testing and prompts reconsidera-tion of whether to modify opioid therapy or refer thepatient to a pain or addiction specialist
A comprehensive evaluation to assess the presence orrisk of misuse and opioid use disorder includes ques-tions about patientsrsquo history of substance use disordersand current clinical characteristics (eg from a physicalexamination) input from patientsrsquo family members andother health care providers (eg psychiatrists previouspain specialists) and pill counts Behaviors that may in-dicate increased likelihood of misuse or opioid use dis-order include requests for early refills [108]unauthorized dose escalations [109] and use of anotherindividualrsquos medication [109] Substance use disorder isgenerally associated with one or more of the four ldquoCsrdquo(ie impaired Control over use Compulsive useContinued use despite harm and Craving) [110]
A few simple questions (eg single-item screeningquestions [SISQs] for alcohol and drug use [93111]) fol-lowed by a discussion with patients is an efficient wayfor clinicians to incorporate risk assessment into theirpractice Reviewing a patientrsquos history of controlled sub-stance prescriptions in the PDMP is another method forassessing potential opioid misuse or substance use dis-order Clinicians should be aware of their statersquos regula-tions recommendations and resources regardingPDMPs [112] All states have or are planning to imple-ment a PDMP but reporting times vary and not everyprovider is required to participate in PDMPs in all states[112ndash114] The Comprehensive Addiction and RecoveryAct of 2016 is intended to improve the efficiency ofthese programs to track prescription drug use and helpprevent inappropriate use [115] Despite their inconsis-tencies PDMPs (when available) have become standardof care as part of patient risk evaluation WhetherPDMP data will predict aberrant behaviors or other ad-verse outcomes is not yet known and represents a gapin the science and an unmet need
Question 3 How Often Should UDM Occur in Patientswith Low Medium and High Risk for Opioid Misuseor Opioid Use Disorder
Expert Panel Recommendation
Perform UDM at baseline in patients prescribed opioidsfor chronic pain During ongoing monitoring performUDM at least annually for low-risk patients two or moretimes per year for moderate-risk patients and three ormore times per year for high-risk patients Additionalmonitoring can be performed at any risk level as fre-quently as necessary according to clinical judgment
Existing Guidelines
Recent guidelines recommend UDM at least annually forall patients regardless of risk [18] every six months totwo years for patients at low risk for opioid misuse oropioid use disorder [202240] one to three times peryear for moderate-risk patients [2022] and at least twoto four times per year for high-risk patients [202240]

The CDC Guideline for Prescribing Opioids for ChronicPain does not recommend tailoring the monitoringschedule according to risk because tools that predictharmful use lack sufficient accuracy [18] Several guide-lines [182122] suggest periodic UDM testing duringscheduled visits truly random testing outside of sched-uled clinic visits may not be feasible in many settings(eg primary care) or appropriate for all patients [18]
Relevant Literature
The identified studies related to UDM frequency do notdifferentiate strategies for low- moderate- and high-risklevels Nevertheless clinical trials assessing the effectsof UDM on outcomes are particularly relevant to deci-sions regarding frequency of monitoring (SupplementaryTable 1) Adherence to prescribed opioids is higher withmore frequent UDM according to a retrospective analy-sis of patients with chronic pain in private practices[116] In two prospective trials at an interventional painmanagement practice adherence monitoring that in-cluded random UDM was associated with reductions inindicators of opioid misuse (determined via periodicchart review UDM pill counts and verification of infor-mation with treating clinicians and pharmacies) [24] andillicit drug use (determined via UDM) [117] In anotherstudy a comprehensive risk reduction strategy includ-ing UDM led to decreased pill confiscations by law en-forcement agents and improved primary care providersrsquoperceptions of the overall quality of pain management[118] A structured program designed to support pri-mary care providers with chronic pain management ledto a greater-than-two-fold increase in UDM 22 months
after initiation of the program which was associatedwith a 727 relative decrease in total emergency de-partment (ED) visits and a 596 relative decrease inunscheduled primary care provider visits per patient onaverage [119]
The main negative clinical consequence of UDMreported in the literature was a lower likelihood ofpatients attending a second visit at an urban academicpain clinic after urine testing was used in the first officevisit [120] Individuals with positive test results for an il-licit substance were less likely to attend the second visitthan those with a negative result [120] Although thisstudy suggests that UDM at first visit may hinderpatient-clinician trust patient response to UDM mayvary by clinical setting by how the rationale for UDM isexplained to the patient and by the degree to whichUDM becomes routine in clinical practice
Many studies showed significant benefits of UDM how-ever a few did not No association between UDM and all-cause mortality was found in VA patients [121] althoughan association was not necessarily expected in this sam-ple of patients with a high burden of comorbiditiesAnother study conducted in a large health care systemshowed that an opioid risk reduction initiative (includingrecommendations on UDM) increased use of UDM with-out affecting rates of unexpected results (eg negative forprescribed opioids or positive for cannabis) [122]
Several studies and surveys of physicians (eg pain andaddiction specialists) nurses PAs and other health careprofessionals mainly from pain practices and academiccenters have assessed the frequency of UDM during

opioid therapy for chronic pain [296580123124]which provides context for recommendations on fre-quency Patients with chronic pain received an averageof 34 UDM tests per year according to a 2007 study ina Kentucky private pain practice [80] The frequency ofUDM testing increased by an average of 34 yearlyfrom 2005 to 2008 in a clinical laboratory serving a largeacademic center [123] Surveys indicated that individualpain and addiction experts differed in their frequency ofUDM use from testing at every office visit to yearly[2965] although most preferred random testing[65124] As a caveat these surveys did not focus onprimary care settings
Expert Panel Discussion
The expert panel did not specify how the relative riskcategories should be determined aside from suggestingseveral potential risk assessment tools and strategies(see the Question 2 section) Baseline UDM testing is tobe performed either before initiation of opioid therapyor for those continuing opioid therapy from another pro-vider within three months of the first office visit If thepatient received UDM testing from another providerwithin the previous year and the results were consistentwith prescribed opioid therapy no immediate retestingmay be needed to continue therapy
Regular UDM is recommended even in low-risk patientsbecause their circumstancesbehaviors can change overthe course of therapy Patients at especially low risk(eg receiving low-dose as-needed opioids) mayrequire infrequent UDM (eg every two years) Moderate-risk patients may become higher or lower risk dependingon their environment and stressors intense monitoring isusually not required in these patients but periodic reevalu-ation of their situationsrisk factors is appropriate
High-risk patients require more frequent individualizedUDM testing than those at low or moderate risk al-though the evidence supporting the effectiveness of in-tense monitoring is weak Most primary care providerscan best care for high-risk patients by referring them toa pain and addiction specialist when available Primarycare clinicians who are trained in chronic pain manage-ment utilize UDM are experienced in interpreting UDMresults and have access to consultant toxicologists maybe able to appropriately care for high-risk patientsandor comanage them with a pain specialist Currentguidelines for UDM in patients with substance usedisorder recommend use of personalized testingregimens [28]
Additional Expert Panel Recommendations andDiscussion
UDM Rationale
Clinicians are encouraged to include information relatedto UDM in patient-provider agreements and explain to
patients that the primary goals of UDM are to improvethe safety and effectiveness of therapy by monitoringadherence Furthermore UDM is strongly recommendedas part of a universal precautions approach [125]Consistent UDM results provide objective data to sup-port decision-making during chronic opioid therapy
UDM Process
The panelists recommend that clinicians discuss theUDM process openly with patients as they do with allother clinical testing and document the time of lastmedication use before urine collection Unexpectedresults may be caused by laboratory errors (eg mislab-eling) or by sample adulteration including substitution ofsynthetic or another individualrsquos urine Signs of tamper-ing include temperature outside the normal range of90 F to 100 F within four minutes of sample collectionpH outside the normal range of 45 to 80 low creati-nine concentration (ie 20 mgdL) low specific gravity(ie 1003) presence of adulterants or detection ofparent drug without metabolites [28] Variation in metab-olite levels may also result from pharmacogenetic anom-alies or drug-drug interactions affecting drugmetabolism [28126]
Strategies to prevent sample tampering depend on theclinical setting and can include observed collection(viewed as overly invasive of a patientrsquos privacy) achain-of-custody protocol (ie documentation for han-dling of the specimen) and a truly random collection(ie a protocol to notify the patients of required testingwithin a set period) [28] Although observed urine sam-ple collection at pain clinics has been recommended[83] this practice and chain-of-custody protocols aretypically not followed Despite risk-mitigation strategiesdedicated individuals can still manipulate their UDMsamples or consume prescribed medication before of-fice visits to conceal misuse or diversion Patients withan opioid use disorder may not be able to control theirdrug use to avoid unexpected UDM results despitescheduled collection
Alcohol Screening
For patients with a substance use disorder alcohol maybe problematic and prohibited in any amount for otherpatients with chronic pain only high-risk alcohol use(eg binge drinking) is a concern Many opioids includeblack box warnings about the concurrent use of alcoholbecause of the potential for fatal overdose [127] Onereviewed guideline recommends screening for alcoholwith UDM in patients with chronic pain [22] ethyl glucu-ronide ethyl sulfate or ethanol in UDM indicates alcoholuse [128] As a caveat immunoassay and definitiveUDM may not differentiate between alcoholic beveragesand alcohol-containing medications mouthwashes andhand sanitizers [28] Instead of UDM the panelists

recommend the SISQ ldquoHow many times in the past yearhave you had (five or more drinks [men] four or moredrinks [women]) in a dayrdquo from the National Institute onAlcohol Abuse and Alcoholism [111] to identify un-healthy alcohol use as this question is simple to admin-ister and is validated [129] In primary care settings thesensitivity of the alcohol SISQ for identifying alcohol usedisorder is 88 and the specificity is 84 [130]
Cannabis Screening
Practices for cannabis screening vary [131] individualprescribers can decide whether detecting cannabis byUDM is appropriate by consulting local laws [132133]and common practice as well as by considering theadvantagesdisadvantages discussed below At the timeof this publication cannabis is federally illegal (ie clas-sified by the US Drug Enforcement Administration asSchedule 1 under the Controlled Substances Act) butseveral states have passed legislation to decriminalize itfor medical andor recreational use [131ndash134] The CDCGuideline for Prescribing Opioids for Chronic Pain indi-cates that the clinical implications of a positive UDM re-sult for cannabis are uncertain [18] the VAUSDepartment of Defense guidelines estimate the length oftime it can be detected in urine [21] and theWashington State guidelines suggest implementing anoffice policy for patients who use cannabis [22] Theseguidelines [182122] and this consensus report do notprovide formal graded recommendations for or againstUDM screening for cannabis or for interpretation of theresults
Clinicians who avoid cannabis testing may miss criticalinformation that could inform patient monitoring and im-prove safety Data from Colorado indicate increased EDvisits hospitalizations and proportions of fatal motor ve-hicle accidents related to cannabis intoxication after de-criminalization [134ndash136] Illegal use of cannabis is amarker for opioid misuse and substance use disorders[137] and a rationale to classify a patient as high riskAnother concern is that patients may divert prescriptionopioids to purchase cannabis
If clinicians choose to assess patientsrsquo nonprescriptioncannabinoid use there is a validated SISQ for drugs in-cluding cannabis (ie ldquoHow many times in the past yearhave you used an illegal drug or used a prescriptionmedication for nonmedical reasonsrdquo) [93] with a sensi-tivity of 97 and a specificity of 79 for substance usedisorders in primary care settings [130] Although somemetabolites of synthetic cannabinoids (eg spice) canbe analyzed with specialized immunoassayschromatographyspectrometry-based assays are betterfor assessing the many emerging synthetic cannabi-noids and their metabolites [138]
A subject of ongoing debate is whether co-administration of opioids and cannabis (used
recreationally or medically) is safe or reasonable for clini-cians to allow Cannabis is increasingly accepted formedical purposes especially for cancer pain syn-dromes However allowing patients with chronic pain touse cannabis is a potential liability for clinicians (includ-ing pharmacists) regardless of the drugrsquos legal status intheir state [139] The safety of cannabis for patients withchronic pain is not clearly established [140] and little isknown regarding the safety of concurrent use withopioids apart from the potential opioid-sparing effects ofcannabis [141] The composition and dose of the manyactive components in cannabis vary widely [133142]which leads to variable toxicity [143] and complicatessafety studies Cannabinoids may inhibit cytochromeP450 2D6 [144] (involved in opioid metabolism [145])and therefore affect both the efficacy of opioids and theability to detect metabolites in UDM The panelists pro-posed that a single clinician be responsible for manag-ing both opioid and cannabis use in states where thedrug has been decriminalized and the benefits of con-current use outweigh the risks
Interpreting UDM Results and Implications forChanging Clinical Practice
The panelists believe that clinicians should follow manu-facturer instructions for specific POC UDM tests and di-rect any questions about interpreting results to anexpert in toxicology or clinical pathology Laboratoriesperforming UDM have a responsibility to provide cleartest results answer questions and offer support on clin-ical decisions When clinicians are confronted with un-expected results potential causes for false-positive andfalse-negative results (eg quinolone antibiotics tolme-tin Figure 1) are important to investigate A summary ofcommunications and discussions about results with thelaboratory and other experts can be included in themedical record to document the medical necessity oftesting and related clinical decision-making
Communications with patients about the purpose andresults of UDM should be nonjudgmental and nonpuni-tive and should focus on safety and risks associatedwith misuse and opioid use disorder To avoid unex-pected results open discussion with patients is recom-mended and may include asking questions such as ldquoIfwe test you today what will we find in your urine Willthere be any surprisesrdquo Development of a plan to ad-dress UDM results that are inconsistent with therapy issuggested to mitigate safety risks for patients and po-tential regulatory board sanctions for clinicians Of noteUDM results that are consistent with prescribed opioidscannot differentiate among appropriate use occasionaluse or misuse and opioid use disorder negative UDMresults for prescribed opioids cannot distinguishbetween infrequent need for medicine overuse and run-ning out falsification of the urine sample and diversionResults of UDM are only part of the clinical information

(eg including patient history) that must be consideredbefore a treatment plan is changed
Detailed recommendations on proper opioid prescribingand appropriate changes to patient care after unex-pected UDM results are outside the scope of this con-sensus report but are discussed in other guidelines[18202240] In brief options to address unexpectedUDM results include open and nonjudgmental discus-sions with patients additional confirmation testing in-creased monitoring a switch to a nonopioid painmedication or referral for treatment of an opioid usedisorder [18202240]
Three studies from the Philadelphia VA Medical Center in-vestigated how UDM results affected provider behavior[119146147] additional research to determine how UDMresults should influence patientsrsquo therapy is warranted Inthe absence of this information a follow-up consensusmeeting to evaluate expert opinion was suggested
Conclusions
In summary the expert panel made the following rec-ommendations regarding UDM (Figure 2)
1 Use definitive UDM testing (eg with GC-MS LC-MS or LC-MSMS) as the most clinically appropriatemethod for assessing baseline opioid use and opioidmisuse in most patients with chronic pain being con-sidered for opioids as well as for ongoing monitoringof patients receiving opioids for chronic pain unlesspresumptive testing is required by institutional orpayer policies A rational approach to choosing themost relevant analytes for UDM testing is proposedand should be documented by the clinician
2 To guide UDM frequency assess and stratify patientsprescribed opioid therapy for chronic pain with thefollowing strategies
bull perform a physical examination and obtain relevantpatient history for eventsdiagnoses and behaviorsthat have been shown to predict opioid misuseand opioid use disorder (eg history of substanceuse disorders psychiatric conditions sexual abuse)including information from previous providers forpatients transferring care
bull use validated tools to assess risk for aberrantmedication-taking behavior opioid misuse opioiduse disorder and the potential for respiratory de-pressionoverdose
bull check PDMPs and previous UDM results whenavailable
3 Perform UDM at baseline in patients receiving opioidsfor chronic pain During ongoing monitoring performUDM at least annually for low-risk patients two ormore times per year for moderate-risk patients andthree or more times per year for high-risk patientsAdditional monitoring can be performed as frequently
as necessary according to clinical judgment (egworrisome patient behavior related to the prescribedmedication)
The recommendations in this consensus report are meantto provide practical advice on implementing rational UDMacross a broad range of clinical practices in a patient-centric manner Some clinicians may not have access toappropriate resources to perform routine definitive UDMor to refer patients to pain specialists alternatives are pro-vided in the expert panel discussion sections Higher-quality studies on patient outcomes with UDM areneeded As a next step a consensus recommendationinitiative similar to this one that discusses appropriate clini-cian actions in response to test results that are inconsis-tent with prescribed therapy is warranted

In contrast to this expert panelrsquos recommendation pre-viously published guidelines suggest that patientsundergo presumptive testing with immunoassay whenthey are prescribed opioids for chronic pain[18202240] some guidelines specify that the testshould be POC [2040] Confirmatory definitive tests aregenerally reserved for resolving unexpected results fromimmunoassays [18202240] or for detecting specificopioids that cannot be identified with standard immu-noassays [18] According to the CDC [18] CMS [58]and other payer policies [5059] definitive testing is ap-propriate only when it affects clinical decision-makingand patient management The Washington State guide-lines suggest considering the following drugs for aUDM panel in addition to medications prescribed alco-hol amphetamines barbiturates benzodiazepinescannabinoids cocaine fentanyl methadone opiatesand oxycodone [22]
Relevant Literature
Surveys indicate that UDM in patients prescribedopioids for chronic pain varies widely (ie 19ndash636of patients receive UDM at some point during treatment[60ndash63] and 69ndash100 of clinicians administer UDM[295263ndash66]) which demonstrates a need for guid-ance Traditionally POC immunoassays have been usedfor initial screening in UDM because they provide rapidresults at relatively low cost [28] However false-positiveresults (eg 22 for opiate immunoassays [32]) can becaused by cross-reactivity [28] and false-negativeresults (eg 30 for opiate assays [32]) may occur be-cause of drug concentration cutoffs and cross-reactivityin particular among drugs in similar chemical classes[67] Some opioids and benzodiazepines are not welldetected by immunoassays [67]
Compared with immunoassays definitive testing candetect a greater number of compounds (eg variousbenzodiazepines [67ndash69]) and demonstrates higher sen-sitivity and specificity [70] The gold standard of defini-tive testing was considered to be GC-MS [71] but LC-MSMS has become a favored method [28] because itis associated with less drug interference and can beperformed with smaller urine volumes than for GC-MS[71] Validation of two new LC-MSMS methods wasidentified through our literature search [7273] As a ca-veat detection of metabolites of some prescriptionopioids (eg buprenorphine by certain routes ofadministration) or illicit substances (eg heroin) with

LC-MSMS is challenging in part because of insufficientsensitivity of tests and individual variation in drug metab-olism [7475]
Although (confirmatory) definitive testing is often used toverify unexpected immunoassay results recent evidencesuggests that it is more accurate than immunoassay atassessing patientsrsquo substance use at initial screening[76ndash78] A hybrid UDM approach in which each drugwas measured with either immunoassay or LC-MS(depending on which platform has better accuracy andspeed for each drug) reduced the need for confirmationtesting and time to results [79] In a study at a privatepain practice clinicians and patients discussed unex-pected results from initial immunoassay UDM and opennonjudgmental communication was emphasized thisapproach led to only 3 to 5 of cases requiring con-firmatory GC-MS testing [80] The clinical utility of a hy-brid immunoassayLC-MS approach and of effectivepatient communication to prevent the need for confir-matory GC-MS testing will need to be furtherestablished
Expert Panel Discussion
The panelists expressed concerns about limited sensitiv-ity and specificity as well as misinterpretation errors withclass-specific immunoassays especially in the primarycare setting The initial low cost of immunoassays maybe negated by their potential inaccuracy which can in-crease the downstream financial burden to confirm con-flicting or unexpected results and potentially increasecosts for additional treatments and office visits when apatient is inappropriately continued or discontinued fromopioids because of misinterpretation of results Definitivetesting although often more expensive than immunoas-say initially includes a more comprehensive panel ofsubstances and is more sensitive and specific fordetecting adherence to prescribed opioids and use ofother substances For these reasons several panelistsconsider definitive testing to be the most rational choicefor UDM and elect to use it exclusively for both prelimi-nary testing and follow-up testing when results are con-tested by the patient
The expert panel recognizes that not all clinicians havereliable access to definitive testing laboratories andsome payers reimburse for definitive testing only afteran immunoassay result is inconsistent with therapy Therecommendations in this consensus are intended to beconsidered together with practical clinical and payerconcerns When required by payers and institutionsimmunoassays may be sufficient for monitoring low-riskpatients particularly when clinicians and patients en-gage in open communication
Given the potentially high cost of definitive testing ratio-nal selection of analytes is recommended Appropriatesubstances to analyze for UDM include all controlled
substances (and selected noncontrolled coanalgesicssuch as antidepressants and anticonvulsants) that a pa-tient is prescribed as well as substances unexpectedlyfound at previous UDM Inclusion of additional medica-tions andor alcohol is driven by their potential for harm(ie risk-relevant testing) For identification of substan-ces most likely to be used and diverted consult recentnational survey results [81] and relevant geographic data[82] Greater numbers of analytes will likely need to betested for patients at higher risk for substance usedisorders
Complexities regarding UDM test properties necessitatethat clinicians have access to an expert (eg toxicolo-gist knowledgeable pain or addiction specialist pathol-ogist) when choosing the most appropriate test andinterpreting unexpected results Clinicians should alsobe aware of relevant state mandates regulations andguidelines [83] descriptions of UDM requirements bystate are available from state medical boards and theAAPM website (httpwwwpainmedorgadvocacystate-updates)
Question 2 How Should Patients Undergoing UDMBe Stratified for Opioid Misuse Risk
Expert Panel Recommendations
To guide UDM frequency assess and stratify patientswho are prescribed opioid therapy for chronic pain withthe following strategies
bull Perform a physical examination and obtain relevantpatient history for eventsdiagnoses and behaviorsthat have been shown to predict opioid misuse andopioid use disorder (eg history of substance use dis-orders psychiatric conditions sexual abuse) includinginformation from previous providers for patients trans-ferring care
bull Use validated tools to assess the risk for aberrantmedication-taking behavior opioid misuse opioid usedisorder and the potential for respiratory depressionoverdose
bull Check prescription drug monitoring programs(PDMPs) and previous UDM results when available
Existing Guidelines
Some guidelines [182022] recommend the use of riskassessment tools to stratify patients receiving opioidsthe Opioid Risk Tool (ORT) and Screener and OpioidAssessment for Patients with PainndashRevised (SOAPPVR -R)are frequently mentioned in other guidelines[18224084] Tools deemed most relevant by panelistson the basis of validation studies and use in practiceare described in Table 2 [18192284ndash94] There is aneed for further clinical validation of existing tools [19]and for development of newer and more accurate toolsthat incorporate additional risk factors [1895] Risk tools

are just one part of a comprehensive patient evaluation[2040]
Relevant Literature
Several tools for predicting and determining current risk ofaberrant medication-taking behaviors (eg lost prescrip-tion request for early refill) opioid misuse and opioid usedisorder are reported in the literature [96ndash99] In a painclinicndashbased study a semistructured clinical interview byan addiction psychologist was more sensitive than theORT Pain Medication Questionnaire and SOAPP-R atpredicting aberrant drug-related behavior [98] TheSOAPP-R showed the highest sensitivity of these self-report measures but may overestimate risk [98]
The use of external information (eg PDMPs) can alsoimprove patient management [100] In a university-based multidisciplinary pain management center misuseand diversion were detected more frequently by addingUDM andor a PDMP check to a baseline strategy ofcomparing patient reports and review of medicalrecords [101] However a systematic review of primarycare pain clinic and Veterans Administration (VA)Medical Center settings concluded that no single proce-dure or set of variables was sufficient to identify patientswith chronic pain who are at risk for opioid misuse orharmful substance use [97]
Expert Panel Discussion
The expert panelists suggest that patients be assessedfor risk of aberrant medication-taking behavior misuseand opioid use disorder to determine the frequency ofUDM A high-dose cutoff alone (eg 120-mg morphineequivalent dose per day [22]) was perceived as being in-adequate for identifying high-risk patients because highdoses may be appropriate to accommodate develop-ment of tolerance in specific patients [192187] In addi-tion patients predisposed to misuse may be at risk ofopioid use disorder or unsafe use even with low tomoderate doses
No specific risk assessment tool or behavioral assess-ment is recommended by panelists Clinicians are en-couraged to choose one or more of the many availabletools that match their preferences and can be incorpo-rated into their electronic medical records and workflow Understanding why specific factors predict risk ismore important than knowledge of the risk assessmenttools themselves (Figure 3 [1997102ndash107]) Risk strati-fication is not static and regular reevaluation of patientcircumstances (eg loss of a job divorce) is recom-mended An unexpected UDM result increases apatientrsquos risk of misuse and opioid use disorder neces-sitates more frequent testing and prompts reconsidera-tion of whether to modify opioid therapy or refer thepatient to a pain or addiction specialist
A comprehensive evaluation to assess the presence orrisk of misuse and opioid use disorder includes ques-tions about patientsrsquo history of substance use disordersand current clinical characteristics (eg from a physicalexamination) input from patientsrsquo family members andother health care providers (eg psychiatrists previouspain specialists) and pill counts Behaviors that may in-dicate increased likelihood of misuse or opioid use dis-order include requests for early refills [108]unauthorized dose escalations [109] and use of anotherindividualrsquos medication [109] Substance use disorder isgenerally associated with one or more of the four ldquoCsrdquo(ie impaired Control over use Compulsive useContinued use despite harm and Craving) [110]
A few simple questions (eg single-item screeningquestions [SISQs] for alcohol and drug use [93111]) fol-lowed by a discussion with patients is an efficient wayfor clinicians to incorporate risk assessment into theirpractice Reviewing a patientrsquos history of controlled sub-stance prescriptions in the PDMP is another method forassessing potential opioid misuse or substance use dis-order Clinicians should be aware of their statersquos regula-tions recommendations and resources regardingPDMPs [112] All states have or are planning to imple-ment a PDMP but reporting times vary and not everyprovider is required to participate in PDMPs in all states[112ndash114] The Comprehensive Addiction and RecoveryAct of 2016 is intended to improve the efficiency ofthese programs to track prescription drug use and helpprevent inappropriate use [115] Despite their inconsis-tencies PDMPs (when available) have become standardof care as part of patient risk evaluation WhetherPDMP data will predict aberrant behaviors or other ad-verse outcomes is not yet known and represents a gapin the science and an unmet need
Question 3 How Often Should UDM Occur in Patientswith Low Medium and High Risk for Opioid Misuseor Opioid Use Disorder
Expert Panel Recommendation
Perform UDM at baseline in patients prescribed opioidsfor chronic pain During ongoing monitoring performUDM at least annually for low-risk patients two or moretimes per year for moderate-risk patients and three ormore times per year for high-risk patients Additionalmonitoring can be performed at any risk level as fre-quently as necessary according to clinical judgment
Existing Guidelines
Recent guidelines recommend UDM at least annually forall patients regardless of risk [18] every six months totwo years for patients at low risk for opioid misuse oropioid use disorder [202240] one to three times peryear for moderate-risk patients [2022] and at least twoto four times per year for high-risk patients [202240]

The CDC Guideline for Prescribing Opioids for ChronicPain does not recommend tailoring the monitoringschedule according to risk because tools that predictharmful use lack sufficient accuracy [18] Several guide-lines [182122] suggest periodic UDM testing duringscheduled visits truly random testing outside of sched-uled clinic visits may not be feasible in many settings(eg primary care) or appropriate for all patients [18]
Relevant Literature
The identified studies related to UDM frequency do notdifferentiate strategies for low- moderate- and high-risklevels Nevertheless clinical trials assessing the effectsof UDM on outcomes are particularly relevant to deci-sions regarding frequency of monitoring (SupplementaryTable 1) Adherence to prescribed opioids is higher withmore frequent UDM according to a retrospective analy-sis of patients with chronic pain in private practices[116] In two prospective trials at an interventional painmanagement practice adherence monitoring that in-cluded random UDM was associated with reductions inindicators of opioid misuse (determined via periodicchart review UDM pill counts and verification of infor-mation with treating clinicians and pharmacies) [24] andillicit drug use (determined via UDM) [117] In anotherstudy a comprehensive risk reduction strategy includ-ing UDM led to decreased pill confiscations by law en-forcement agents and improved primary care providersrsquoperceptions of the overall quality of pain management[118] A structured program designed to support pri-mary care providers with chronic pain management ledto a greater-than-two-fold increase in UDM 22 months
after initiation of the program which was associatedwith a 727 relative decrease in total emergency de-partment (ED) visits and a 596 relative decrease inunscheduled primary care provider visits per patient onaverage [119]
The main negative clinical consequence of UDMreported in the literature was a lower likelihood ofpatients attending a second visit at an urban academicpain clinic after urine testing was used in the first officevisit [120] Individuals with positive test results for an il-licit substance were less likely to attend the second visitthan those with a negative result [120] Although thisstudy suggests that UDM at first visit may hinderpatient-clinician trust patient response to UDM mayvary by clinical setting by how the rationale for UDM isexplained to the patient and by the degree to whichUDM becomes routine in clinical practice
Many studies showed significant benefits of UDM how-ever a few did not No association between UDM and all-cause mortality was found in VA patients [121] althoughan association was not necessarily expected in this sam-ple of patients with a high burden of comorbiditiesAnother study conducted in a large health care systemshowed that an opioid risk reduction initiative (includingrecommendations on UDM) increased use of UDM with-out affecting rates of unexpected results (eg negative forprescribed opioids or positive for cannabis) [122]
Several studies and surveys of physicians (eg pain andaddiction specialists) nurses PAs and other health careprofessionals mainly from pain practices and academiccenters have assessed the frequency of UDM during

opioid therapy for chronic pain [296580123124]which provides context for recommendations on fre-quency Patients with chronic pain received an averageof 34 UDM tests per year according to a 2007 study ina Kentucky private pain practice [80] The frequency ofUDM testing increased by an average of 34 yearlyfrom 2005 to 2008 in a clinical laboratory serving a largeacademic center [123] Surveys indicated that individualpain and addiction experts differed in their frequency ofUDM use from testing at every office visit to yearly[2965] although most preferred random testing[65124] As a caveat these surveys did not focus onprimary care settings
Expert Panel Discussion
The expert panel did not specify how the relative riskcategories should be determined aside from suggestingseveral potential risk assessment tools and strategies(see the Question 2 section) Baseline UDM testing is tobe performed either before initiation of opioid therapyor for those continuing opioid therapy from another pro-vider within three months of the first office visit If thepatient received UDM testing from another providerwithin the previous year and the results were consistentwith prescribed opioid therapy no immediate retestingmay be needed to continue therapy
Regular UDM is recommended even in low-risk patientsbecause their circumstancesbehaviors can change overthe course of therapy Patients at especially low risk(eg receiving low-dose as-needed opioids) mayrequire infrequent UDM (eg every two years) Moderate-risk patients may become higher or lower risk dependingon their environment and stressors intense monitoring isusually not required in these patients but periodic reevalu-ation of their situationsrisk factors is appropriate
High-risk patients require more frequent individualizedUDM testing than those at low or moderate risk al-though the evidence supporting the effectiveness of in-tense monitoring is weak Most primary care providerscan best care for high-risk patients by referring them toa pain and addiction specialist when available Primarycare clinicians who are trained in chronic pain manage-ment utilize UDM are experienced in interpreting UDMresults and have access to consultant toxicologists maybe able to appropriately care for high-risk patientsandor comanage them with a pain specialist Currentguidelines for UDM in patients with substance usedisorder recommend use of personalized testingregimens [28]
Additional Expert Panel Recommendations andDiscussion
UDM Rationale
Clinicians are encouraged to include information relatedto UDM in patient-provider agreements and explain to
patients that the primary goals of UDM are to improvethe safety and effectiveness of therapy by monitoringadherence Furthermore UDM is strongly recommendedas part of a universal precautions approach [125]Consistent UDM results provide objective data to sup-port decision-making during chronic opioid therapy
UDM Process
The panelists recommend that clinicians discuss theUDM process openly with patients as they do with allother clinical testing and document the time of lastmedication use before urine collection Unexpectedresults may be caused by laboratory errors (eg mislab-eling) or by sample adulteration including substitution ofsynthetic or another individualrsquos urine Signs of tamper-ing include temperature outside the normal range of90 F to 100 F within four minutes of sample collectionpH outside the normal range of 45 to 80 low creati-nine concentration (ie 20 mgdL) low specific gravity(ie 1003) presence of adulterants or detection ofparent drug without metabolites [28] Variation in metab-olite levels may also result from pharmacogenetic anom-alies or drug-drug interactions affecting drugmetabolism [28126]
Strategies to prevent sample tampering depend on theclinical setting and can include observed collection(viewed as overly invasive of a patientrsquos privacy) achain-of-custody protocol (ie documentation for han-dling of the specimen) and a truly random collection(ie a protocol to notify the patients of required testingwithin a set period) [28] Although observed urine sam-ple collection at pain clinics has been recommended[83] this practice and chain-of-custody protocols aretypically not followed Despite risk-mitigation strategiesdedicated individuals can still manipulate their UDMsamples or consume prescribed medication before of-fice visits to conceal misuse or diversion Patients withan opioid use disorder may not be able to control theirdrug use to avoid unexpected UDM results despitescheduled collection
Alcohol Screening
For patients with a substance use disorder alcohol maybe problematic and prohibited in any amount for otherpatients with chronic pain only high-risk alcohol use(eg binge drinking) is a concern Many opioids includeblack box warnings about the concurrent use of alcoholbecause of the potential for fatal overdose [127] Onereviewed guideline recommends screening for alcoholwith UDM in patients with chronic pain [22] ethyl glucu-ronide ethyl sulfate or ethanol in UDM indicates alcoholuse [128] As a caveat immunoassay and definitiveUDM may not differentiate between alcoholic beveragesand alcohol-containing medications mouthwashes andhand sanitizers [28] Instead of UDM the panelists

recommend the SISQ ldquoHow many times in the past yearhave you had (five or more drinks [men] four or moredrinks [women]) in a dayrdquo from the National Institute onAlcohol Abuse and Alcoholism [111] to identify un-healthy alcohol use as this question is simple to admin-ister and is validated [129] In primary care settings thesensitivity of the alcohol SISQ for identifying alcohol usedisorder is 88 and the specificity is 84 [130]
Cannabis Screening
Practices for cannabis screening vary [131] individualprescribers can decide whether detecting cannabis byUDM is appropriate by consulting local laws [132133]and common practice as well as by considering theadvantagesdisadvantages discussed below At the timeof this publication cannabis is federally illegal (ie clas-sified by the US Drug Enforcement Administration asSchedule 1 under the Controlled Substances Act) butseveral states have passed legislation to decriminalize itfor medical andor recreational use [131ndash134] The CDCGuideline for Prescribing Opioids for Chronic Pain indi-cates that the clinical implications of a positive UDM re-sult for cannabis are uncertain [18] the VAUSDepartment of Defense guidelines estimate the length oftime it can be detected in urine [21] and theWashington State guidelines suggest implementing anoffice policy for patients who use cannabis [22] Theseguidelines [182122] and this consensus report do notprovide formal graded recommendations for or againstUDM screening for cannabis or for interpretation of theresults
Clinicians who avoid cannabis testing may miss criticalinformation that could inform patient monitoring and im-prove safety Data from Colorado indicate increased EDvisits hospitalizations and proportions of fatal motor ve-hicle accidents related to cannabis intoxication after de-criminalization [134ndash136] Illegal use of cannabis is amarker for opioid misuse and substance use disorders[137] and a rationale to classify a patient as high riskAnother concern is that patients may divert prescriptionopioids to purchase cannabis
If clinicians choose to assess patientsrsquo nonprescriptioncannabinoid use there is a validated SISQ for drugs in-cluding cannabis (ie ldquoHow many times in the past yearhave you used an illegal drug or used a prescriptionmedication for nonmedical reasonsrdquo) [93] with a sensi-tivity of 97 and a specificity of 79 for substance usedisorders in primary care settings [130] Although somemetabolites of synthetic cannabinoids (eg spice) canbe analyzed with specialized immunoassayschromatographyspectrometry-based assays are betterfor assessing the many emerging synthetic cannabi-noids and their metabolites [138]
A subject of ongoing debate is whether co-administration of opioids and cannabis (used
recreationally or medically) is safe or reasonable for clini-cians to allow Cannabis is increasingly accepted formedical purposes especially for cancer pain syn-dromes However allowing patients with chronic pain touse cannabis is a potential liability for clinicians (includ-ing pharmacists) regardless of the drugrsquos legal status intheir state [139] The safety of cannabis for patients withchronic pain is not clearly established [140] and little isknown regarding the safety of concurrent use withopioids apart from the potential opioid-sparing effects ofcannabis [141] The composition and dose of the manyactive components in cannabis vary widely [133142]which leads to variable toxicity [143] and complicatessafety studies Cannabinoids may inhibit cytochromeP450 2D6 [144] (involved in opioid metabolism [145])and therefore affect both the efficacy of opioids and theability to detect metabolites in UDM The panelists pro-posed that a single clinician be responsible for manag-ing both opioid and cannabis use in states where thedrug has been decriminalized and the benefits of con-current use outweigh the risks
Interpreting UDM Results and Implications forChanging Clinical Practice
The panelists believe that clinicians should follow manu-facturer instructions for specific POC UDM tests and di-rect any questions about interpreting results to anexpert in toxicology or clinical pathology Laboratoriesperforming UDM have a responsibility to provide cleartest results answer questions and offer support on clin-ical decisions When clinicians are confronted with un-expected results potential causes for false-positive andfalse-negative results (eg quinolone antibiotics tolme-tin Figure 1) are important to investigate A summary ofcommunications and discussions about results with thelaboratory and other experts can be included in themedical record to document the medical necessity oftesting and related clinical decision-making
Communications with patients about the purpose andresults of UDM should be nonjudgmental and nonpuni-tive and should focus on safety and risks associatedwith misuse and opioid use disorder To avoid unex-pected results open discussion with patients is recom-mended and may include asking questions such as ldquoIfwe test you today what will we find in your urine Willthere be any surprisesrdquo Development of a plan to ad-dress UDM results that are inconsistent with therapy issuggested to mitigate safety risks for patients and po-tential regulatory board sanctions for clinicians Of noteUDM results that are consistent with prescribed opioidscannot differentiate among appropriate use occasionaluse or misuse and opioid use disorder negative UDMresults for prescribed opioids cannot distinguishbetween infrequent need for medicine overuse and run-ning out falsification of the urine sample and diversionResults of UDM are only part of the clinical information

(eg including patient history) that must be consideredbefore a treatment plan is changed
Detailed recommendations on proper opioid prescribingand appropriate changes to patient care after unex-pected UDM results are outside the scope of this con-sensus report but are discussed in other guidelines[18202240] In brief options to address unexpectedUDM results include open and nonjudgmental discus-sions with patients additional confirmation testing in-creased monitoring a switch to a nonopioid painmedication or referral for treatment of an opioid usedisorder [18202240]
Three studies from the Philadelphia VA Medical Center in-vestigated how UDM results affected provider behavior[119146147] additional research to determine how UDMresults should influence patientsrsquo therapy is warranted Inthe absence of this information a follow-up consensusmeeting to evaluate expert opinion was suggested
Conclusions
In summary the expert panel made the following rec-ommendations regarding UDM (Figure 2)
1 Use definitive UDM testing (eg with GC-MS LC-MS or LC-MSMS) as the most clinically appropriatemethod for assessing baseline opioid use and opioidmisuse in most patients with chronic pain being con-sidered for opioids as well as for ongoing monitoringof patients receiving opioids for chronic pain unlesspresumptive testing is required by institutional orpayer policies A rational approach to choosing themost relevant analytes for UDM testing is proposedand should be documented by the clinician
2 To guide UDM frequency assess and stratify patientsprescribed opioid therapy for chronic pain with thefollowing strategies
bull perform a physical examination and obtain relevantpatient history for eventsdiagnoses and behaviorsthat have been shown to predict opioid misuseand opioid use disorder (eg history of substanceuse disorders psychiatric conditions sexual abuse)including information from previous providers forpatients transferring care
bull use validated tools to assess risk for aberrantmedication-taking behavior opioid misuse opioiduse disorder and the potential for respiratory de-pressionoverdose
bull check PDMPs and previous UDM results whenavailable
3 Perform UDM at baseline in patients receiving opioidsfor chronic pain During ongoing monitoring performUDM at least annually for low-risk patients two ormore times per year for moderate-risk patients andthree or more times per year for high-risk patientsAdditional monitoring can be performed as frequently
as necessary according to clinical judgment (egworrisome patient behavior related to the prescribedmedication)
The recommendations in this consensus report are meantto provide practical advice on implementing rational UDMacross a broad range of clinical practices in a patient-centric manner Some clinicians may not have access toappropriate resources to perform routine definitive UDMor to refer patients to pain specialists alternatives are pro-vided in the expert panel discussion sections Higher-quality studies on patient outcomes with UDM areneeded As a next step a consensus recommendationinitiative similar to this one that discusses appropriate clini-cian actions in response to test results that are inconsis-tent with prescribed therapy is warranted

LC-MSMS is challenging in part because of insufficientsensitivity of tests and individual variation in drug metab-olism [7475]
Although (confirmatory) definitive testing is often used toverify unexpected immunoassay results recent evidencesuggests that it is more accurate than immunoassay atassessing patientsrsquo substance use at initial screening[76ndash78] A hybrid UDM approach in which each drugwas measured with either immunoassay or LC-MS(depending on which platform has better accuracy andspeed for each drug) reduced the need for confirmationtesting and time to results [79] In a study at a privatepain practice clinicians and patients discussed unex-pected results from initial immunoassay UDM and opennonjudgmental communication was emphasized thisapproach led to only 3 to 5 of cases requiring con-firmatory GC-MS testing [80] The clinical utility of a hy-brid immunoassayLC-MS approach and of effectivepatient communication to prevent the need for confir-matory GC-MS testing will need to be furtherestablished
Expert Panel Discussion
The panelists expressed concerns about limited sensitiv-ity and specificity as well as misinterpretation errors withclass-specific immunoassays especially in the primarycare setting The initial low cost of immunoassays maybe negated by their potential inaccuracy which can in-crease the downstream financial burden to confirm con-flicting or unexpected results and potentially increasecosts for additional treatments and office visits when apatient is inappropriately continued or discontinued fromopioids because of misinterpretation of results Definitivetesting although often more expensive than immunoas-say initially includes a more comprehensive panel ofsubstances and is more sensitive and specific fordetecting adherence to prescribed opioids and use ofother substances For these reasons several panelistsconsider definitive testing to be the most rational choicefor UDM and elect to use it exclusively for both prelimi-nary testing and follow-up testing when results are con-tested by the patient
The expert panel recognizes that not all clinicians havereliable access to definitive testing laboratories andsome payers reimburse for definitive testing only afteran immunoassay result is inconsistent with therapy Therecommendations in this consensus are intended to beconsidered together with practical clinical and payerconcerns When required by payers and institutionsimmunoassays may be sufficient for monitoring low-riskpatients particularly when clinicians and patients en-gage in open communication
Given the potentially high cost of definitive testing ratio-nal selection of analytes is recommended Appropriatesubstances to analyze for UDM include all controlled
substances (and selected noncontrolled coanalgesicssuch as antidepressants and anticonvulsants) that a pa-tient is prescribed as well as substances unexpectedlyfound at previous UDM Inclusion of additional medica-tions andor alcohol is driven by their potential for harm(ie risk-relevant testing) For identification of substan-ces most likely to be used and diverted consult recentnational survey results [81] and relevant geographic data[82] Greater numbers of analytes will likely need to betested for patients at higher risk for substance usedisorders
Complexities regarding UDM test properties necessitatethat clinicians have access to an expert (eg toxicolo-gist knowledgeable pain or addiction specialist pathol-ogist) when choosing the most appropriate test andinterpreting unexpected results Clinicians should alsobe aware of relevant state mandates regulations andguidelines [83] descriptions of UDM requirements bystate are available from state medical boards and theAAPM website (httpwwwpainmedorgadvocacystate-updates)
Question 2 How Should Patients Undergoing UDMBe Stratified for Opioid Misuse Risk
Expert Panel Recommendations
To guide UDM frequency assess and stratify patientswho are prescribed opioid therapy for chronic pain withthe following strategies
bull Perform a physical examination and obtain relevantpatient history for eventsdiagnoses and behaviorsthat have been shown to predict opioid misuse andopioid use disorder (eg history of substance use dis-orders psychiatric conditions sexual abuse) includinginformation from previous providers for patients trans-ferring care
bull Use validated tools to assess the risk for aberrantmedication-taking behavior opioid misuse opioid usedisorder and the potential for respiratory depressionoverdose
bull Check prescription drug monitoring programs(PDMPs) and previous UDM results when available
Existing Guidelines
Some guidelines [182022] recommend the use of riskassessment tools to stratify patients receiving opioidsthe Opioid Risk Tool (ORT) and Screener and OpioidAssessment for Patients with PainndashRevised (SOAPPVR -R)are frequently mentioned in other guidelines[18224084] Tools deemed most relevant by panelistson the basis of validation studies and use in practiceare described in Table 2 [18192284ndash94] There is aneed for further clinical validation of existing tools [19]and for development of newer and more accurate toolsthat incorporate additional risk factors [1895] Risk tools

are just one part of a comprehensive patient evaluation[2040]
Relevant Literature
Several tools for predicting and determining current risk ofaberrant medication-taking behaviors (eg lost prescrip-tion request for early refill) opioid misuse and opioid usedisorder are reported in the literature [96ndash99] In a painclinicndashbased study a semistructured clinical interview byan addiction psychologist was more sensitive than theORT Pain Medication Questionnaire and SOAPP-R atpredicting aberrant drug-related behavior [98] TheSOAPP-R showed the highest sensitivity of these self-report measures but may overestimate risk [98]
The use of external information (eg PDMPs) can alsoimprove patient management [100] In a university-based multidisciplinary pain management center misuseand diversion were detected more frequently by addingUDM andor a PDMP check to a baseline strategy ofcomparing patient reports and review of medicalrecords [101] However a systematic review of primarycare pain clinic and Veterans Administration (VA)Medical Center settings concluded that no single proce-dure or set of variables was sufficient to identify patientswith chronic pain who are at risk for opioid misuse orharmful substance use [97]
Expert Panel Discussion
The expert panelists suggest that patients be assessedfor risk of aberrant medication-taking behavior misuseand opioid use disorder to determine the frequency ofUDM A high-dose cutoff alone (eg 120-mg morphineequivalent dose per day [22]) was perceived as being in-adequate for identifying high-risk patients because highdoses may be appropriate to accommodate develop-ment of tolerance in specific patients [192187] In addi-tion patients predisposed to misuse may be at risk ofopioid use disorder or unsafe use even with low tomoderate doses
No specific risk assessment tool or behavioral assess-ment is recommended by panelists Clinicians are en-couraged to choose one or more of the many availabletools that match their preferences and can be incorpo-rated into their electronic medical records and workflow Understanding why specific factors predict risk ismore important than knowledge of the risk assessmenttools themselves (Figure 3 [1997102ndash107]) Risk strati-fication is not static and regular reevaluation of patientcircumstances (eg loss of a job divorce) is recom-mended An unexpected UDM result increases apatientrsquos risk of misuse and opioid use disorder neces-sitates more frequent testing and prompts reconsidera-tion of whether to modify opioid therapy or refer thepatient to a pain or addiction specialist
A comprehensive evaluation to assess the presence orrisk of misuse and opioid use disorder includes ques-tions about patientsrsquo history of substance use disordersand current clinical characteristics (eg from a physicalexamination) input from patientsrsquo family members andother health care providers (eg psychiatrists previouspain specialists) and pill counts Behaviors that may in-dicate increased likelihood of misuse or opioid use dis-order include requests for early refills [108]unauthorized dose escalations [109] and use of anotherindividualrsquos medication [109] Substance use disorder isgenerally associated with one or more of the four ldquoCsrdquo(ie impaired Control over use Compulsive useContinued use despite harm and Craving) [110]
A few simple questions (eg single-item screeningquestions [SISQs] for alcohol and drug use [93111]) fol-lowed by a discussion with patients is an efficient wayfor clinicians to incorporate risk assessment into theirpractice Reviewing a patientrsquos history of controlled sub-stance prescriptions in the PDMP is another method forassessing potential opioid misuse or substance use dis-order Clinicians should be aware of their statersquos regula-tions recommendations and resources regardingPDMPs [112] All states have or are planning to imple-ment a PDMP but reporting times vary and not everyprovider is required to participate in PDMPs in all states[112ndash114] The Comprehensive Addiction and RecoveryAct of 2016 is intended to improve the efficiency ofthese programs to track prescription drug use and helpprevent inappropriate use [115] Despite their inconsis-tencies PDMPs (when available) have become standardof care as part of patient risk evaluation WhetherPDMP data will predict aberrant behaviors or other ad-verse outcomes is not yet known and represents a gapin the science and an unmet need
Question 3 How Often Should UDM Occur in Patientswith Low Medium and High Risk for Opioid Misuseor Opioid Use Disorder
Expert Panel Recommendation
Perform UDM at baseline in patients prescribed opioidsfor chronic pain During ongoing monitoring performUDM at least annually for low-risk patients two or moretimes per year for moderate-risk patients and three ormore times per year for high-risk patients Additionalmonitoring can be performed at any risk level as fre-quently as necessary according to clinical judgment
Existing Guidelines
Recent guidelines recommend UDM at least annually forall patients regardless of risk [18] every six months totwo years for patients at low risk for opioid misuse oropioid use disorder [202240] one to three times peryear for moderate-risk patients [2022] and at least twoto four times per year for high-risk patients [202240]

The CDC Guideline for Prescribing Opioids for ChronicPain does not recommend tailoring the monitoringschedule according to risk because tools that predictharmful use lack sufficient accuracy [18] Several guide-lines [182122] suggest periodic UDM testing duringscheduled visits truly random testing outside of sched-uled clinic visits may not be feasible in many settings(eg primary care) or appropriate for all patients [18]
Relevant Literature
The identified studies related to UDM frequency do notdifferentiate strategies for low- moderate- and high-risklevels Nevertheless clinical trials assessing the effectsof UDM on outcomes are particularly relevant to deci-sions regarding frequency of monitoring (SupplementaryTable 1) Adherence to prescribed opioids is higher withmore frequent UDM according to a retrospective analy-sis of patients with chronic pain in private practices[116] In two prospective trials at an interventional painmanagement practice adherence monitoring that in-cluded random UDM was associated with reductions inindicators of opioid misuse (determined via periodicchart review UDM pill counts and verification of infor-mation with treating clinicians and pharmacies) [24] andillicit drug use (determined via UDM) [117] In anotherstudy a comprehensive risk reduction strategy includ-ing UDM led to decreased pill confiscations by law en-forcement agents and improved primary care providersrsquoperceptions of the overall quality of pain management[118] A structured program designed to support pri-mary care providers with chronic pain management ledto a greater-than-two-fold increase in UDM 22 months
after initiation of the program which was associatedwith a 727 relative decrease in total emergency de-partment (ED) visits and a 596 relative decrease inunscheduled primary care provider visits per patient onaverage [119]
The main negative clinical consequence of UDMreported in the literature was a lower likelihood ofpatients attending a second visit at an urban academicpain clinic after urine testing was used in the first officevisit [120] Individuals with positive test results for an il-licit substance were less likely to attend the second visitthan those with a negative result [120] Although thisstudy suggests that UDM at first visit may hinderpatient-clinician trust patient response to UDM mayvary by clinical setting by how the rationale for UDM isexplained to the patient and by the degree to whichUDM becomes routine in clinical practice
Many studies showed significant benefits of UDM how-ever a few did not No association between UDM and all-cause mortality was found in VA patients [121] althoughan association was not necessarily expected in this sam-ple of patients with a high burden of comorbiditiesAnother study conducted in a large health care systemshowed that an opioid risk reduction initiative (includingrecommendations on UDM) increased use of UDM with-out affecting rates of unexpected results (eg negative forprescribed opioids or positive for cannabis) [122]
Several studies and surveys of physicians (eg pain andaddiction specialists) nurses PAs and other health careprofessionals mainly from pain practices and academiccenters have assessed the frequency of UDM during

opioid therapy for chronic pain [296580123124]which provides context for recommendations on fre-quency Patients with chronic pain received an averageof 34 UDM tests per year according to a 2007 study ina Kentucky private pain practice [80] The frequency ofUDM testing increased by an average of 34 yearlyfrom 2005 to 2008 in a clinical laboratory serving a largeacademic center [123] Surveys indicated that individualpain and addiction experts differed in their frequency ofUDM use from testing at every office visit to yearly[2965] although most preferred random testing[65124] As a caveat these surveys did not focus onprimary care settings
Expert Panel Discussion
The expert panel did not specify how the relative riskcategories should be determined aside from suggestingseveral potential risk assessment tools and strategies(see the Question 2 section) Baseline UDM testing is tobe performed either before initiation of opioid therapyor for those continuing opioid therapy from another pro-vider within three months of the first office visit If thepatient received UDM testing from another providerwithin the previous year and the results were consistentwith prescribed opioid therapy no immediate retestingmay be needed to continue therapy
Regular UDM is recommended even in low-risk patientsbecause their circumstancesbehaviors can change overthe course of therapy Patients at especially low risk(eg receiving low-dose as-needed opioids) mayrequire infrequent UDM (eg every two years) Moderate-risk patients may become higher or lower risk dependingon their environment and stressors intense monitoring isusually not required in these patients but periodic reevalu-ation of their situationsrisk factors is appropriate
High-risk patients require more frequent individualizedUDM testing than those at low or moderate risk al-though the evidence supporting the effectiveness of in-tense monitoring is weak Most primary care providerscan best care for high-risk patients by referring them toa pain and addiction specialist when available Primarycare clinicians who are trained in chronic pain manage-ment utilize UDM are experienced in interpreting UDMresults and have access to consultant toxicologists maybe able to appropriately care for high-risk patientsandor comanage them with a pain specialist Currentguidelines for UDM in patients with substance usedisorder recommend use of personalized testingregimens [28]
Additional Expert Panel Recommendations andDiscussion
UDM Rationale
Clinicians are encouraged to include information relatedto UDM in patient-provider agreements and explain to
patients that the primary goals of UDM are to improvethe safety and effectiveness of therapy by monitoringadherence Furthermore UDM is strongly recommendedas part of a universal precautions approach [125]Consistent UDM results provide objective data to sup-port decision-making during chronic opioid therapy
UDM Process
The panelists recommend that clinicians discuss theUDM process openly with patients as they do with allother clinical testing and document the time of lastmedication use before urine collection Unexpectedresults may be caused by laboratory errors (eg mislab-eling) or by sample adulteration including substitution ofsynthetic or another individualrsquos urine Signs of tamper-ing include temperature outside the normal range of90 F to 100 F within four minutes of sample collectionpH outside the normal range of 45 to 80 low creati-nine concentration (ie 20 mgdL) low specific gravity(ie 1003) presence of adulterants or detection ofparent drug without metabolites [28] Variation in metab-olite levels may also result from pharmacogenetic anom-alies or drug-drug interactions affecting drugmetabolism [28126]
Strategies to prevent sample tampering depend on theclinical setting and can include observed collection(viewed as overly invasive of a patientrsquos privacy) achain-of-custody protocol (ie documentation for han-dling of the specimen) and a truly random collection(ie a protocol to notify the patients of required testingwithin a set period) [28] Although observed urine sam-ple collection at pain clinics has been recommended[83] this practice and chain-of-custody protocols aretypically not followed Despite risk-mitigation strategiesdedicated individuals can still manipulate their UDMsamples or consume prescribed medication before of-fice visits to conceal misuse or diversion Patients withan opioid use disorder may not be able to control theirdrug use to avoid unexpected UDM results despitescheduled collection
Alcohol Screening
For patients with a substance use disorder alcohol maybe problematic and prohibited in any amount for otherpatients with chronic pain only high-risk alcohol use(eg binge drinking) is a concern Many opioids includeblack box warnings about the concurrent use of alcoholbecause of the potential for fatal overdose [127] Onereviewed guideline recommends screening for alcoholwith UDM in patients with chronic pain [22] ethyl glucu-ronide ethyl sulfate or ethanol in UDM indicates alcoholuse [128] As a caveat immunoassay and definitiveUDM may not differentiate between alcoholic beveragesand alcohol-containing medications mouthwashes andhand sanitizers [28] Instead of UDM the panelists

recommend the SISQ ldquoHow many times in the past yearhave you had (five or more drinks [men] four or moredrinks [women]) in a dayrdquo from the National Institute onAlcohol Abuse and Alcoholism [111] to identify un-healthy alcohol use as this question is simple to admin-ister and is validated [129] In primary care settings thesensitivity of the alcohol SISQ for identifying alcohol usedisorder is 88 and the specificity is 84 [130]
Cannabis Screening
Practices for cannabis screening vary [131] individualprescribers can decide whether detecting cannabis byUDM is appropriate by consulting local laws [132133]and common practice as well as by considering theadvantagesdisadvantages discussed below At the timeof this publication cannabis is federally illegal (ie clas-sified by the US Drug Enforcement Administration asSchedule 1 under the Controlled Substances Act) butseveral states have passed legislation to decriminalize itfor medical andor recreational use [131ndash134] The CDCGuideline for Prescribing Opioids for Chronic Pain indi-cates that the clinical implications of a positive UDM re-sult for cannabis are uncertain [18] the VAUSDepartment of Defense guidelines estimate the length oftime it can be detected in urine [21] and theWashington State guidelines suggest implementing anoffice policy for patients who use cannabis [22] Theseguidelines [182122] and this consensus report do notprovide formal graded recommendations for or againstUDM screening for cannabis or for interpretation of theresults
Clinicians who avoid cannabis testing may miss criticalinformation that could inform patient monitoring and im-prove safety Data from Colorado indicate increased EDvisits hospitalizations and proportions of fatal motor ve-hicle accidents related to cannabis intoxication after de-criminalization [134ndash136] Illegal use of cannabis is amarker for opioid misuse and substance use disorders[137] and a rationale to classify a patient as high riskAnother concern is that patients may divert prescriptionopioids to purchase cannabis
If clinicians choose to assess patientsrsquo nonprescriptioncannabinoid use there is a validated SISQ for drugs in-cluding cannabis (ie ldquoHow many times in the past yearhave you used an illegal drug or used a prescriptionmedication for nonmedical reasonsrdquo) [93] with a sensi-tivity of 97 and a specificity of 79 for substance usedisorders in primary care settings [130] Although somemetabolites of synthetic cannabinoids (eg spice) canbe analyzed with specialized immunoassayschromatographyspectrometry-based assays are betterfor assessing the many emerging synthetic cannabi-noids and their metabolites [138]
A subject of ongoing debate is whether co-administration of opioids and cannabis (used
recreationally or medically) is safe or reasonable for clini-cians to allow Cannabis is increasingly accepted formedical purposes especially for cancer pain syn-dromes However allowing patients with chronic pain touse cannabis is a potential liability for clinicians (includ-ing pharmacists) regardless of the drugrsquos legal status intheir state [139] The safety of cannabis for patients withchronic pain is not clearly established [140] and little isknown regarding the safety of concurrent use withopioids apart from the potential opioid-sparing effects ofcannabis [141] The composition and dose of the manyactive components in cannabis vary widely [133142]which leads to variable toxicity [143] and complicatessafety studies Cannabinoids may inhibit cytochromeP450 2D6 [144] (involved in opioid metabolism [145])and therefore affect both the efficacy of opioids and theability to detect metabolites in UDM The panelists pro-posed that a single clinician be responsible for manag-ing both opioid and cannabis use in states where thedrug has been decriminalized and the benefits of con-current use outweigh the risks
Interpreting UDM Results and Implications forChanging Clinical Practice
The panelists believe that clinicians should follow manu-facturer instructions for specific POC UDM tests and di-rect any questions about interpreting results to anexpert in toxicology or clinical pathology Laboratoriesperforming UDM have a responsibility to provide cleartest results answer questions and offer support on clin-ical decisions When clinicians are confronted with un-expected results potential causes for false-positive andfalse-negative results (eg quinolone antibiotics tolme-tin Figure 1) are important to investigate A summary ofcommunications and discussions about results with thelaboratory and other experts can be included in themedical record to document the medical necessity oftesting and related clinical decision-making
Communications with patients about the purpose andresults of UDM should be nonjudgmental and nonpuni-tive and should focus on safety and risks associatedwith misuse and opioid use disorder To avoid unex-pected results open discussion with patients is recom-mended and may include asking questions such as ldquoIfwe test you today what will we find in your urine Willthere be any surprisesrdquo Development of a plan to ad-dress UDM results that are inconsistent with therapy issuggested to mitigate safety risks for patients and po-tential regulatory board sanctions for clinicians Of noteUDM results that are consistent with prescribed opioidscannot differentiate among appropriate use occasionaluse or misuse and opioid use disorder negative UDMresults for prescribed opioids cannot distinguishbetween infrequent need for medicine overuse and run-ning out falsification of the urine sample and diversionResults of UDM are only part of the clinical information

(eg including patient history) that must be consideredbefore a treatment plan is changed
Detailed recommendations on proper opioid prescribingand appropriate changes to patient care after unex-pected UDM results are outside the scope of this con-sensus report but are discussed in other guidelines[18202240] In brief options to address unexpectedUDM results include open and nonjudgmental discus-sions with patients additional confirmation testing in-creased monitoring a switch to a nonopioid painmedication or referral for treatment of an opioid usedisorder [18202240]
Three studies from the Philadelphia VA Medical Center in-vestigated how UDM results affected provider behavior[119146147] additional research to determine how UDMresults should influence patientsrsquo therapy is warranted Inthe absence of this information a follow-up consensusmeeting to evaluate expert opinion was suggested
Conclusions
In summary the expert panel made the following rec-ommendations regarding UDM (Figure 2)
1 Use definitive UDM testing (eg with GC-MS LC-MS or LC-MSMS) as the most clinically appropriatemethod for assessing baseline opioid use and opioidmisuse in most patients with chronic pain being con-sidered for opioids as well as for ongoing monitoringof patients receiving opioids for chronic pain unlesspresumptive testing is required by institutional orpayer policies A rational approach to choosing themost relevant analytes for UDM testing is proposedand should be documented by the clinician
2 To guide UDM frequency assess and stratify patientsprescribed opioid therapy for chronic pain with thefollowing strategies
bull perform a physical examination and obtain relevantpatient history for eventsdiagnoses and behaviorsthat have been shown to predict opioid misuseand opioid use disorder (eg history of substanceuse disorders psychiatric conditions sexual abuse)including information from previous providers forpatients transferring care
bull use validated tools to assess risk for aberrantmedication-taking behavior opioid misuse opioiduse disorder and the potential for respiratory de-pressionoverdose
bull check PDMPs and previous UDM results whenavailable
3 Perform UDM at baseline in patients receiving opioidsfor chronic pain During ongoing monitoring performUDM at least annually for low-risk patients two ormore times per year for moderate-risk patients andthree or more times per year for high-risk patientsAdditional monitoring can be performed as frequently
as necessary according to clinical judgment (egworrisome patient behavior related to the prescribedmedication)
The recommendations in this consensus report are meantto provide practical advice on implementing rational UDMacross a broad range of clinical practices in a patient-centric manner Some clinicians may not have access toappropriate resources to perform routine definitive UDMor to refer patients to pain specialists alternatives are pro-vided in the expert panel discussion sections Higher-quality studies on patient outcomes with UDM areneeded As a next step a consensus recommendationinitiative similar to this one that discusses appropriate clini-cian actions in response to test results that are inconsis-tent with prescribed therapy is warranted

are just one part of a comprehensive patient evaluation[2040]
Relevant Literature
Several tools for predicting and determining current risk ofaberrant medication-taking behaviors (eg lost prescrip-tion request for early refill) opioid misuse and opioid usedisorder are reported in the literature [96ndash99] In a painclinicndashbased study a semistructured clinical interview byan addiction psychologist was more sensitive than theORT Pain Medication Questionnaire and SOAPP-R atpredicting aberrant drug-related behavior [98] TheSOAPP-R showed the highest sensitivity of these self-report measures but may overestimate risk [98]
The use of external information (eg PDMPs) can alsoimprove patient management [100] In a university-based multidisciplinary pain management center misuseand diversion were detected more frequently by addingUDM andor a PDMP check to a baseline strategy ofcomparing patient reports and review of medicalrecords [101] However a systematic review of primarycare pain clinic and Veterans Administration (VA)Medical Center settings concluded that no single proce-dure or set of variables was sufficient to identify patientswith chronic pain who are at risk for opioid misuse orharmful substance use [97]
Expert Panel Discussion
The expert panelists suggest that patients be assessedfor risk of aberrant medication-taking behavior misuseand opioid use disorder to determine the frequency ofUDM A high-dose cutoff alone (eg 120-mg morphineequivalent dose per day [22]) was perceived as being in-adequate for identifying high-risk patients because highdoses may be appropriate to accommodate develop-ment of tolerance in specific patients [192187] In addi-tion patients predisposed to misuse may be at risk ofopioid use disorder or unsafe use even with low tomoderate doses
No specific risk assessment tool or behavioral assess-ment is recommended by panelists Clinicians are en-couraged to choose one or more of the many availabletools that match their preferences and can be incorpo-rated into their electronic medical records and workflow Understanding why specific factors predict risk ismore important than knowledge of the risk assessmenttools themselves (Figure 3 [1997102ndash107]) Risk strati-fication is not static and regular reevaluation of patientcircumstances (eg loss of a job divorce) is recom-mended An unexpected UDM result increases apatientrsquos risk of misuse and opioid use disorder neces-sitates more frequent testing and prompts reconsidera-tion of whether to modify opioid therapy or refer thepatient to a pain or addiction specialist
A comprehensive evaluation to assess the presence orrisk of misuse and opioid use disorder includes ques-tions about patientsrsquo history of substance use disordersand current clinical characteristics (eg from a physicalexamination) input from patientsrsquo family members andother health care providers (eg psychiatrists previouspain specialists) and pill counts Behaviors that may in-dicate increased likelihood of misuse or opioid use dis-order include requests for early refills [108]unauthorized dose escalations [109] and use of anotherindividualrsquos medication [109] Substance use disorder isgenerally associated with one or more of the four ldquoCsrdquo(ie impaired Control over use Compulsive useContinued use despite harm and Craving) [110]
A few simple questions (eg single-item screeningquestions [SISQs] for alcohol and drug use [93111]) fol-lowed by a discussion with patients is an efficient wayfor clinicians to incorporate risk assessment into theirpractice Reviewing a patientrsquos history of controlled sub-stance prescriptions in the PDMP is another method forassessing potential opioid misuse or substance use dis-order Clinicians should be aware of their statersquos regula-tions recommendations and resources regardingPDMPs [112] All states have or are planning to imple-ment a PDMP but reporting times vary and not everyprovider is required to participate in PDMPs in all states[112ndash114] The Comprehensive Addiction and RecoveryAct of 2016 is intended to improve the efficiency ofthese programs to track prescription drug use and helpprevent inappropriate use [115] Despite their inconsis-tencies PDMPs (when available) have become standardof care as part of patient risk evaluation WhetherPDMP data will predict aberrant behaviors or other ad-verse outcomes is not yet known and represents a gapin the science and an unmet need
Question 3 How Often Should UDM Occur in Patientswith Low Medium and High Risk for Opioid Misuseor Opioid Use Disorder
Expert Panel Recommendation
Perform UDM at baseline in patients prescribed opioidsfor chronic pain During ongoing monitoring performUDM at least annually for low-risk patients two or moretimes per year for moderate-risk patients and three ormore times per year for high-risk patients Additionalmonitoring can be performed at any risk level as fre-quently as necessary according to clinical judgment
Existing Guidelines
Recent guidelines recommend UDM at least annually forall patients regardless of risk [18] every six months totwo years for patients at low risk for opioid misuse oropioid use disorder [202240] one to three times peryear for moderate-risk patients [2022] and at least twoto four times per year for high-risk patients [202240]

The CDC Guideline for Prescribing Opioids for ChronicPain does not recommend tailoring the monitoringschedule according to risk because tools that predictharmful use lack sufficient accuracy [18] Several guide-lines [182122] suggest periodic UDM testing duringscheduled visits truly random testing outside of sched-uled clinic visits may not be feasible in many settings(eg primary care) or appropriate for all patients [18]
Relevant Literature
The identified studies related to UDM frequency do notdifferentiate strategies for low- moderate- and high-risklevels Nevertheless clinical trials assessing the effectsof UDM on outcomes are particularly relevant to deci-sions regarding frequency of monitoring (SupplementaryTable 1) Adherence to prescribed opioids is higher withmore frequent UDM according to a retrospective analy-sis of patients with chronic pain in private practices[116] In two prospective trials at an interventional painmanagement practice adherence monitoring that in-cluded random UDM was associated with reductions inindicators of opioid misuse (determined via periodicchart review UDM pill counts and verification of infor-mation with treating clinicians and pharmacies) [24] andillicit drug use (determined via UDM) [117] In anotherstudy a comprehensive risk reduction strategy includ-ing UDM led to decreased pill confiscations by law en-forcement agents and improved primary care providersrsquoperceptions of the overall quality of pain management[118] A structured program designed to support pri-mary care providers with chronic pain management ledto a greater-than-two-fold increase in UDM 22 months
after initiation of the program which was associatedwith a 727 relative decrease in total emergency de-partment (ED) visits and a 596 relative decrease inunscheduled primary care provider visits per patient onaverage [119]
The main negative clinical consequence of UDMreported in the literature was a lower likelihood ofpatients attending a second visit at an urban academicpain clinic after urine testing was used in the first officevisit [120] Individuals with positive test results for an il-licit substance were less likely to attend the second visitthan those with a negative result [120] Although thisstudy suggests that UDM at first visit may hinderpatient-clinician trust patient response to UDM mayvary by clinical setting by how the rationale for UDM isexplained to the patient and by the degree to whichUDM becomes routine in clinical practice
Many studies showed significant benefits of UDM how-ever a few did not No association between UDM and all-cause mortality was found in VA patients [121] althoughan association was not necessarily expected in this sam-ple of patients with a high burden of comorbiditiesAnother study conducted in a large health care systemshowed that an opioid risk reduction initiative (includingrecommendations on UDM) increased use of UDM with-out affecting rates of unexpected results (eg negative forprescribed opioids or positive for cannabis) [122]
Several studies and surveys of physicians (eg pain andaddiction specialists) nurses PAs and other health careprofessionals mainly from pain practices and academiccenters have assessed the frequency of UDM during

opioid therapy for chronic pain [296580123124]which provides context for recommendations on fre-quency Patients with chronic pain received an averageof 34 UDM tests per year according to a 2007 study ina Kentucky private pain practice [80] The frequency ofUDM testing increased by an average of 34 yearlyfrom 2005 to 2008 in a clinical laboratory serving a largeacademic center [123] Surveys indicated that individualpain and addiction experts differed in their frequency ofUDM use from testing at every office visit to yearly[2965] although most preferred random testing[65124] As a caveat these surveys did not focus onprimary care settings
Expert Panel Discussion
The expert panel did not specify how the relative riskcategories should be determined aside from suggestingseveral potential risk assessment tools and strategies(see the Question 2 section) Baseline UDM testing is tobe performed either before initiation of opioid therapyor for those continuing opioid therapy from another pro-vider within three months of the first office visit If thepatient received UDM testing from another providerwithin the previous year and the results were consistentwith prescribed opioid therapy no immediate retestingmay be needed to continue therapy
Regular UDM is recommended even in low-risk patientsbecause their circumstancesbehaviors can change overthe course of therapy Patients at especially low risk(eg receiving low-dose as-needed opioids) mayrequire infrequent UDM (eg every two years) Moderate-risk patients may become higher or lower risk dependingon their environment and stressors intense monitoring isusually not required in these patients but periodic reevalu-ation of their situationsrisk factors is appropriate
High-risk patients require more frequent individualizedUDM testing than those at low or moderate risk al-though the evidence supporting the effectiveness of in-tense monitoring is weak Most primary care providerscan best care for high-risk patients by referring them toa pain and addiction specialist when available Primarycare clinicians who are trained in chronic pain manage-ment utilize UDM are experienced in interpreting UDMresults and have access to consultant toxicologists maybe able to appropriately care for high-risk patientsandor comanage them with a pain specialist Currentguidelines for UDM in patients with substance usedisorder recommend use of personalized testingregimens [28]
Additional Expert Panel Recommendations andDiscussion
UDM Rationale
Clinicians are encouraged to include information relatedto UDM in patient-provider agreements and explain to
patients that the primary goals of UDM are to improvethe safety and effectiveness of therapy by monitoringadherence Furthermore UDM is strongly recommendedas part of a universal precautions approach [125]Consistent UDM results provide objective data to sup-port decision-making during chronic opioid therapy
UDM Process
The panelists recommend that clinicians discuss theUDM process openly with patients as they do with allother clinical testing and document the time of lastmedication use before urine collection Unexpectedresults may be caused by laboratory errors (eg mislab-eling) or by sample adulteration including substitution ofsynthetic or another individualrsquos urine Signs of tamper-ing include temperature outside the normal range of90 F to 100 F within four minutes of sample collectionpH outside the normal range of 45 to 80 low creati-nine concentration (ie 20 mgdL) low specific gravity(ie 1003) presence of adulterants or detection ofparent drug without metabolites [28] Variation in metab-olite levels may also result from pharmacogenetic anom-alies or drug-drug interactions affecting drugmetabolism [28126]
Strategies to prevent sample tampering depend on theclinical setting and can include observed collection(viewed as overly invasive of a patientrsquos privacy) achain-of-custody protocol (ie documentation for han-dling of the specimen) and a truly random collection(ie a protocol to notify the patients of required testingwithin a set period) [28] Although observed urine sam-ple collection at pain clinics has been recommended[83] this practice and chain-of-custody protocols aretypically not followed Despite risk-mitigation strategiesdedicated individuals can still manipulate their UDMsamples or consume prescribed medication before of-fice visits to conceal misuse or diversion Patients withan opioid use disorder may not be able to control theirdrug use to avoid unexpected UDM results despitescheduled collection
Alcohol Screening
For patients with a substance use disorder alcohol maybe problematic and prohibited in any amount for otherpatients with chronic pain only high-risk alcohol use(eg binge drinking) is a concern Many opioids includeblack box warnings about the concurrent use of alcoholbecause of the potential for fatal overdose [127] Onereviewed guideline recommends screening for alcoholwith UDM in patients with chronic pain [22] ethyl glucu-ronide ethyl sulfate or ethanol in UDM indicates alcoholuse [128] As a caveat immunoassay and definitiveUDM may not differentiate between alcoholic beveragesand alcohol-containing medications mouthwashes andhand sanitizers [28] Instead of UDM the panelists

recommend the SISQ ldquoHow many times in the past yearhave you had (five or more drinks [men] four or moredrinks [women]) in a dayrdquo from the National Institute onAlcohol Abuse and Alcoholism [111] to identify un-healthy alcohol use as this question is simple to admin-ister and is validated [129] In primary care settings thesensitivity of the alcohol SISQ for identifying alcohol usedisorder is 88 and the specificity is 84 [130]
Cannabis Screening
Practices for cannabis screening vary [131] individualprescribers can decide whether detecting cannabis byUDM is appropriate by consulting local laws [132133]and common practice as well as by considering theadvantagesdisadvantages discussed below At the timeof this publication cannabis is federally illegal (ie clas-sified by the US Drug Enforcement Administration asSchedule 1 under the Controlled Substances Act) butseveral states have passed legislation to decriminalize itfor medical andor recreational use [131ndash134] The CDCGuideline for Prescribing Opioids for Chronic Pain indi-cates that the clinical implications of a positive UDM re-sult for cannabis are uncertain [18] the VAUSDepartment of Defense guidelines estimate the length oftime it can be detected in urine [21] and theWashington State guidelines suggest implementing anoffice policy for patients who use cannabis [22] Theseguidelines [182122] and this consensus report do notprovide formal graded recommendations for or againstUDM screening for cannabis or for interpretation of theresults
Clinicians who avoid cannabis testing may miss criticalinformation that could inform patient monitoring and im-prove safety Data from Colorado indicate increased EDvisits hospitalizations and proportions of fatal motor ve-hicle accidents related to cannabis intoxication after de-criminalization [134ndash136] Illegal use of cannabis is amarker for opioid misuse and substance use disorders[137] and a rationale to classify a patient as high riskAnother concern is that patients may divert prescriptionopioids to purchase cannabis
If clinicians choose to assess patientsrsquo nonprescriptioncannabinoid use there is a validated SISQ for drugs in-cluding cannabis (ie ldquoHow many times in the past yearhave you used an illegal drug or used a prescriptionmedication for nonmedical reasonsrdquo) [93] with a sensi-tivity of 97 and a specificity of 79 for substance usedisorders in primary care settings [130] Although somemetabolites of synthetic cannabinoids (eg spice) canbe analyzed with specialized immunoassayschromatographyspectrometry-based assays are betterfor assessing the many emerging synthetic cannabi-noids and their metabolites [138]
A subject of ongoing debate is whether co-administration of opioids and cannabis (used
recreationally or medically) is safe or reasonable for clini-cians to allow Cannabis is increasingly accepted formedical purposes especially for cancer pain syn-dromes However allowing patients with chronic pain touse cannabis is a potential liability for clinicians (includ-ing pharmacists) regardless of the drugrsquos legal status intheir state [139] The safety of cannabis for patients withchronic pain is not clearly established [140] and little isknown regarding the safety of concurrent use withopioids apart from the potential opioid-sparing effects ofcannabis [141] The composition and dose of the manyactive components in cannabis vary widely [133142]which leads to variable toxicity [143] and complicatessafety studies Cannabinoids may inhibit cytochromeP450 2D6 [144] (involved in opioid metabolism [145])and therefore affect both the efficacy of opioids and theability to detect metabolites in UDM The panelists pro-posed that a single clinician be responsible for manag-ing both opioid and cannabis use in states where thedrug has been decriminalized and the benefits of con-current use outweigh the risks
Interpreting UDM Results and Implications forChanging Clinical Practice
The panelists believe that clinicians should follow manu-facturer instructions for specific POC UDM tests and di-rect any questions about interpreting results to anexpert in toxicology or clinical pathology Laboratoriesperforming UDM have a responsibility to provide cleartest results answer questions and offer support on clin-ical decisions When clinicians are confronted with un-expected results potential causes for false-positive andfalse-negative results (eg quinolone antibiotics tolme-tin Figure 1) are important to investigate A summary ofcommunications and discussions about results with thelaboratory and other experts can be included in themedical record to document the medical necessity oftesting and related clinical decision-making
Communications with patients about the purpose andresults of UDM should be nonjudgmental and nonpuni-tive and should focus on safety and risks associatedwith misuse and opioid use disorder To avoid unex-pected results open discussion with patients is recom-mended and may include asking questions such as ldquoIfwe test you today what will we find in your urine Willthere be any surprisesrdquo Development of a plan to ad-dress UDM results that are inconsistent with therapy issuggested to mitigate safety risks for patients and po-tential regulatory board sanctions for clinicians Of noteUDM results that are consistent with prescribed opioidscannot differentiate among appropriate use occasionaluse or misuse and opioid use disorder negative UDMresults for prescribed opioids cannot distinguishbetween infrequent need for medicine overuse and run-ning out falsification of the urine sample and diversionResults of UDM are only part of the clinical information

(eg including patient history) that must be consideredbefore a treatment plan is changed
Detailed recommendations on proper opioid prescribingand appropriate changes to patient care after unex-pected UDM results are outside the scope of this con-sensus report but are discussed in other guidelines[18202240] In brief options to address unexpectedUDM results include open and nonjudgmental discus-sions with patients additional confirmation testing in-creased monitoring a switch to a nonopioid painmedication or referral for treatment of an opioid usedisorder [18202240]
Three studies from the Philadelphia VA Medical Center in-vestigated how UDM results affected provider behavior[119146147] additional research to determine how UDMresults should influence patientsrsquo therapy is warranted Inthe absence of this information a follow-up consensusmeeting to evaluate expert opinion was suggested
Conclusions
In summary the expert panel made the following rec-ommendations regarding UDM (Figure 2)
1 Use definitive UDM testing (eg with GC-MS LC-MS or LC-MSMS) as the most clinically appropriatemethod for assessing baseline opioid use and opioidmisuse in most patients with chronic pain being con-sidered for opioids as well as for ongoing monitoringof patients receiving opioids for chronic pain unlesspresumptive testing is required by institutional orpayer policies A rational approach to choosing themost relevant analytes for UDM testing is proposedand should be documented by the clinician
2 To guide UDM frequency assess and stratify patientsprescribed opioid therapy for chronic pain with thefollowing strategies
bull perform a physical examination and obtain relevantpatient history for eventsdiagnoses and behaviorsthat have been shown to predict opioid misuseand opioid use disorder (eg history of substanceuse disorders psychiatric conditions sexual abuse)including information from previous providers forpatients transferring care
bull use validated tools to assess risk for aberrantmedication-taking behavior opioid misuse opioiduse disorder and the potential for respiratory de-pressionoverdose
bull check PDMPs and previous UDM results whenavailable
3 Perform UDM at baseline in patients receiving opioidsfor chronic pain During ongoing monitoring performUDM at least annually for low-risk patients two ormore times per year for moderate-risk patients andthree or more times per year for high-risk patientsAdditional monitoring can be performed as frequently
as necessary according to clinical judgment (egworrisome patient behavior related to the prescribedmedication)
The recommendations in this consensus report are meantto provide practical advice on implementing rational UDMacross a broad range of clinical practices in a patient-centric manner Some clinicians may not have access toappropriate resources to perform routine definitive UDMor to refer patients to pain specialists alternatives are pro-vided in the expert panel discussion sections Higher-quality studies on patient outcomes with UDM areneeded As a next step a consensus recommendationinitiative similar to this one that discusses appropriate clini-cian actions in response to test results that are inconsis-tent with prescribed therapy is warranted

are just one part of a comprehensive patient evaluation[2040]
Relevant Literature
Several tools for predicting and determining current risk ofaberrant medication-taking behaviors (eg lost prescrip-tion request for early refill) opioid misuse and opioid usedisorder are reported in the literature [96ndash99] In a painclinicndashbased study a semistructured clinical interview byan addiction psychologist was more sensitive than theORT Pain Medication Questionnaire and SOAPP-R atpredicting aberrant drug-related behavior [98] TheSOAPP-R showed the highest sensitivity of these self-report measures but may overestimate risk [98]
The use of external information (eg PDMPs) can alsoimprove patient management [100] In a university-based multidisciplinary pain management center misuseand diversion were detected more frequently by addingUDM andor a PDMP check to a baseline strategy ofcomparing patient reports and review of medicalrecords [101] However a systematic review of primarycare pain clinic and Veterans Administration (VA)Medical Center settings concluded that no single proce-dure or set of variables was sufficient to identify patientswith chronic pain who are at risk for opioid misuse orharmful substance use [97]
Expert Panel Discussion
The expert panelists suggest that patients be assessedfor risk of aberrant medication-taking behavior misuseand opioid use disorder to determine the frequency ofUDM A high-dose cutoff alone (eg 120-mg morphineequivalent dose per day [22]) was perceived as being in-adequate for identifying high-risk patients because highdoses may be appropriate to accommodate develop-ment of tolerance in specific patients [192187] In addi-tion patients predisposed to misuse may be at risk ofopioid use disorder or unsafe use even with low tomoderate doses
No specific risk assessment tool or behavioral assess-ment is recommended by panelists Clinicians are en-couraged to choose one or more of the many availabletools that match their preferences and can be incorpo-rated into their electronic medical records and workflow Understanding why specific factors predict risk ismore important than knowledge of the risk assessmenttools themselves (Figure 3 [1997102ndash107]) Risk strati-fication is not static and regular reevaluation of patientcircumstances (eg loss of a job divorce) is recom-mended An unexpected UDM result increases apatientrsquos risk of misuse and opioid use disorder neces-sitates more frequent testing and prompts reconsidera-tion of whether to modify opioid therapy or refer thepatient to a pain or addiction specialist
A comprehensive evaluation to assess the presence orrisk of misuse and opioid use disorder includes ques-tions about patientsrsquo history of substance use disordersand current clinical characteristics (eg from a physicalexamination) input from patientsrsquo family members andother health care providers (eg psychiatrists previouspain specialists) and pill counts Behaviors that may in-dicate increased likelihood of misuse or opioid use dis-order include requests for early refills [108]unauthorized dose escalations [109] and use of anotherindividualrsquos medication [109] Substance use disorder isgenerally associated with one or more of the four ldquoCsrdquo(ie impaired Control over use Compulsive useContinued use despite harm and Craving) [110]
A few simple questions (eg single-item screeningquestions [SISQs] for alcohol and drug use [93111]) fol-lowed by a discussion with patients is an efficient wayfor clinicians to incorporate risk assessment into theirpractice Reviewing a patientrsquos history of controlled sub-stance prescriptions in the PDMP is another method forassessing potential opioid misuse or substance use dis-order Clinicians should be aware of their statersquos regula-tions recommendations and resources regardingPDMPs [112] All states have or are planning to imple-ment a PDMP but reporting times vary and not everyprovider is required to participate in PDMPs in all states[112ndash114] The Comprehensive Addiction and RecoveryAct of 2016 is intended to improve the efficiency ofthese programs to track prescription drug use and helpprevent inappropriate use [115] Despite their inconsis-tencies PDMPs (when available) have become standardof care as part of patient risk evaluation WhetherPDMP data will predict aberrant behaviors or other ad-verse outcomes is not yet known and represents a gapin the science and an unmet need
Question 3 How Often Should UDM Occur in Patientswith Low Medium and High Risk for Opioid Misuseor Opioid Use Disorder
Expert Panel Recommendation
Perform UDM at baseline in patients prescribed opioidsfor chronic pain During ongoing monitoring performUDM at least annually for low-risk patients two or moretimes per year for moderate-risk patients and three ormore times per year for high-risk patients Additionalmonitoring can be performed at any risk level as fre-quently as necessary according to clinical judgment
Existing Guidelines
Recent guidelines recommend UDM at least annually forall patients regardless of risk [18] every six months totwo years for patients at low risk for opioid misuse oropioid use disorder [202240] one to three times peryear for moderate-risk patients [2022] and at least twoto four times per year for high-risk patients [202240]

The CDC Guideline for Prescribing Opioids for ChronicPain does not recommend tailoring the monitoringschedule according to risk because tools that predictharmful use lack sufficient accuracy [18] Several guide-lines [182122] suggest periodic UDM testing duringscheduled visits truly random testing outside of sched-uled clinic visits may not be feasible in many settings(eg primary care) or appropriate for all patients [18]
Relevant Literature
The identified studies related to UDM frequency do notdifferentiate strategies for low- moderate- and high-risklevels Nevertheless clinical trials assessing the effectsof UDM on outcomes are particularly relevant to deci-sions regarding frequency of monitoring (SupplementaryTable 1) Adherence to prescribed opioids is higher withmore frequent UDM according to a retrospective analy-sis of patients with chronic pain in private practices[116] In two prospective trials at an interventional painmanagement practice adherence monitoring that in-cluded random UDM was associated with reductions inindicators of opioid misuse (determined via periodicchart review UDM pill counts and verification of infor-mation with treating clinicians and pharmacies) [24] andillicit drug use (determined via UDM) [117] In anotherstudy a comprehensive risk reduction strategy includ-ing UDM led to decreased pill confiscations by law en-forcement agents and improved primary care providersrsquoperceptions of the overall quality of pain management[118] A structured program designed to support pri-mary care providers with chronic pain management ledto a greater-than-two-fold increase in UDM 22 months
after initiation of the program which was associatedwith a 727 relative decrease in total emergency de-partment (ED) visits and a 596 relative decrease inunscheduled primary care provider visits per patient onaverage [119]
The main negative clinical consequence of UDMreported in the literature was a lower likelihood ofpatients attending a second visit at an urban academicpain clinic after urine testing was used in the first officevisit [120] Individuals with positive test results for an il-licit substance were less likely to attend the second visitthan those with a negative result [120] Although thisstudy suggests that UDM at first visit may hinderpatient-clinician trust patient response to UDM mayvary by clinical setting by how the rationale for UDM isexplained to the patient and by the degree to whichUDM becomes routine in clinical practice
Many studies showed significant benefits of UDM how-ever a few did not No association between UDM and all-cause mortality was found in VA patients [121] althoughan association was not necessarily expected in this sam-ple of patients with a high burden of comorbiditiesAnother study conducted in a large health care systemshowed that an opioid risk reduction initiative (includingrecommendations on UDM) increased use of UDM with-out affecting rates of unexpected results (eg negative forprescribed opioids or positive for cannabis) [122]
Several studies and surveys of physicians (eg pain andaddiction specialists) nurses PAs and other health careprofessionals mainly from pain practices and academiccenters have assessed the frequency of UDM during

opioid therapy for chronic pain [296580123124]which provides context for recommendations on fre-quency Patients with chronic pain received an averageof 34 UDM tests per year according to a 2007 study ina Kentucky private pain practice [80] The frequency ofUDM testing increased by an average of 34 yearlyfrom 2005 to 2008 in a clinical laboratory serving a largeacademic center [123] Surveys indicated that individualpain and addiction experts differed in their frequency ofUDM use from testing at every office visit to yearly[2965] although most preferred random testing[65124] As a caveat these surveys did not focus onprimary care settings
Expert Panel Discussion
The expert panel did not specify how the relative riskcategories should be determined aside from suggestingseveral potential risk assessment tools and strategies(see the Question 2 section) Baseline UDM testing is tobe performed either before initiation of opioid therapyor for those continuing opioid therapy from another pro-vider within three months of the first office visit If thepatient received UDM testing from another providerwithin the previous year and the results were consistentwith prescribed opioid therapy no immediate retestingmay be needed to continue therapy
Regular UDM is recommended even in low-risk patientsbecause their circumstancesbehaviors can change overthe course of therapy Patients at especially low risk(eg receiving low-dose as-needed opioids) mayrequire infrequent UDM (eg every two years) Moderate-risk patients may become higher or lower risk dependingon their environment and stressors intense monitoring isusually not required in these patients but periodic reevalu-ation of their situationsrisk factors is appropriate
High-risk patients require more frequent individualizedUDM testing than those at low or moderate risk al-though the evidence supporting the effectiveness of in-tense monitoring is weak Most primary care providerscan best care for high-risk patients by referring them toa pain and addiction specialist when available Primarycare clinicians who are trained in chronic pain manage-ment utilize UDM are experienced in interpreting UDMresults and have access to consultant toxicologists maybe able to appropriately care for high-risk patientsandor comanage them with a pain specialist Currentguidelines for UDM in patients with substance usedisorder recommend use of personalized testingregimens [28]
Additional Expert Panel Recommendations andDiscussion
UDM Rationale
Clinicians are encouraged to include information relatedto UDM in patient-provider agreements and explain to
patients that the primary goals of UDM are to improvethe safety and effectiveness of therapy by monitoringadherence Furthermore UDM is strongly recommendedas part of a universal precautions approach [125]Consistent UDM results provide objective data to sup-port decision-making during chronic opioid therapy
UDM Process
The panelists recommend that clinicians discuss theUDM process openly with patients as they do with allother clinical testing and document the time of lastmedication use before urine collection Unexpectedresults may be caused by laboratory errors (eg mislab-eling) or by sample adulteration including substitution ofsynthetic or another individualrsquos urine Signs of tamper-ing include temperature outside the normal range of90 F to 100 F within four minutes of sample collectionpH outside the normal range of 45 to 80 low creati-nine concentration (ie 20 mgdL) low specific gravity(ie 1003) presence of adulterants or detection ofparent drug without metabolites [28] Variation in metab-olite levels may also result from pharmacogenetic anom-alies or drug-drug interactions affecting drugmetabolism [28126]
Strategies to prevent sample tampering depend on theclinical setting and can include observed collection(viewed as overly invasive of a patientrsquos privacy) achain-of-custody protocol (ie documentation for han-dling of the specimen) and a truly random collection(ie a protocol to notify the patients of required testingwithin a set period) [28] Although observed urine sam-ple collection at pain clinics has been recommended[83] this practice and chain-of-custody protocols aretypically not followed Despite risk-mitigation strategiesdedicated individuals can still manipulate their UDMsamples or consume prescribed medication before of-fice visits to conceal misuse or diversion Patients withan opioid use disorder may not be able to control theirdrug use to avoid unexpected UDM results despitescheduled collection
Alcohol Screening
For patients with a substance use disorder alcohol maybe problematic and prohibited in any amount for otherpatients with chronic pain only high-risk alcohol use(eg binge drinking) is a concern Many opioids includeblack box warnings about the concurrent use of alcoholbecause of the potential for fatal overdose [127] Onereviewed guideline recommends screening for alcoholwith UDM in patients with chronic pain [22] ethyl glucu-ronide ethyl sulfate or ethanol in UDM indicates alcoholuse [128] As a caveat immunoassay and definitiveUDM may not differentiate between alcoholic beveragesand alcohol-containing medications mouthwashes andhand sanitizers [28] Instead of UDM the panelists

recommend the SISQ ldquoHow many times in the past yearhave you had (five or more drinks [men] four or moredrinks [women]) in a dayrdquo from the National Institute onAlcohol Abuse and Alcoholism [111] to identify un-healthy alcohol use as this question is simple to admin-ister and is validated [129] In primary care settings thesensitivity of the alcohol SISQ for identifying alcohol usedisorder is 88 and the specificity is 84 [130]
Cannabis Screening
Practices for cannabis screening vary [131] individualprescribers can decide whether detecting cannabis byUDM is appropriate by consulting local laws [132133]and common practice as well as by considering theadvantagesdisadvantages discussed below At the timeof this publication cannabis is federally illegal (ie clas-sified by the US Drug Enforcement Administration asSchedule 1 under the Controlled Substances Act) butseveral states have passed legislation to decriminalize itfor medical andor recreational use [131ndash134] The CDCGuideline for Prescribing Opioids for Chronic Pain indi-cates that the clinical implications of a positive UDM re-sult for cannabis are uncertain [18] the VAUSDepartment of Defense guidelines estimate the length oftime it can be detected in urine [21] and theWashington State guidelines suggest implementing anoffice policy for patients who use cannabis [22] Theseguidelines [182122] and this consensus report do notprovide formal graded recommendations for or againstUDM screening for cannabis or for interpretation of theresults
Clinicians who avoid cannabis testing may miss criticalinformation that could inform patient monitoring and im-prove safety Data from Colorado indicate increased EDvisits hospitalizations and proportions of fatal motor ve-hicle accidents related to cannabis intoxication after de-criminalization [134ndash136] Illegal use of cannabis is amarker for opioid misuse and substance use disorders[137] and a rationale to classify a patient as high riskAnother concern is that patients may divert prescriptionopioids to purchase cannabis
If clinicians choose to assess patientsrsquo nonprescriptioncannabinoid use there is a validated SISQ for drugs in-cluding cannabis (ie ldquoHow many times in the past yearhave you used an illegal drug or used a prescriptionmedication for nonmedical reasonsrdquo) [93] with a sensi-tivity of 97 and a specificity of 79 for substance usedisorders in primary care settings [130] Although somemetabolites of synthetic cannabinoids (eg spice) canbe analyzed with specialized immunoassayschromatographyspectrometry-based assays are betterfor assessing the many emerging synthetic cannabi-noids and their metabolites [138]
A subject of ongoing debate is whether co-administration of opioids and cannabis (used
recreationally or medically) is safe or reasonable for clini-cians to allow Cannabis is increasingly accepted formedical purposes especially for cancer pain syn-dromes However allowing patients with chronic pain touse cannabis is a potential liability for clinicians (includ-ing pharmacists) regardless of the drugrsquos legal status intheir state [139] The safety of cannabis for patients withchronic pain is not clearly established [140] and little isknown regarding the safety of concurrent use withopioids apart from the potential opioid-sparing effects ofcannabis [141] The composition and dose of the manyactive components in cannabis vary widely [133142]which leads to variable toxicity [143] and complicatessafety studies Cannabinoids may inhibit cytochromeP450 2D6 [144] (involved in opioid metabolism [145])and therefore affect both the efficacy of opioids and theability to detect metabolites in UDM The panelists pro-posed that a single clinician be responsible for manag-ing both opioid and cannabis use in states where thedrug has been decriminalized and the benefits of con-current use outweigh the risks
Interpreting UDM Results and Implications forChanging Clinical Practice
The panelists believe that clinicians should follow manu-facturer instructions for specific POC UDM tests and di-rect any questions about interpreting results to anexpert in toxicology or clinical pathology Laboratoriesperforming UDM have a responsibility to provide cleartest results answer questions and offer support on clin-ical decisions When clinicians are confronted with un-expected results potential causes for false-positive andfalse-negative results (eg quinolone antibiotics tolme-tin Figure 1) are important to investigate A summary ofcommunications and discussions about results with thelaboratory and other experts can be included in themedical record to document the medical necessity oftesting and related clinical decision-making
Communications with patients about the purpose andresults of UDM should be nonjudgmental and nonpuni-tive and should focus on safety and risks associatedwith misuse and opioid use disorder To avoid unex-pected results open discussion with patients is recom-mended and may include asking questions such as ldquoIfwe test you today what will we find in your urine Willthere be any surprisesrdquo Development of a plan to ad-dress UDM results that are inconsistent with therapy issuggested to mitigate safety risks for patients and po-tential regulatory board sanctions for clinicians Of noteUDM results that are consistent with prescribed opioidscannot differentiate among appropriate use occasionaluse or misuse and opioid use disorder negative UDMresults for prescribed opioids cannot distinguishbetween infrequent need for medicine overuse and run-ning out falsification of the urine sample and diversionResults of UDM are only part of the clinical information

(eg including patient history) that must be consideredbefore a treatment plan is changed
Detailed recommendations on proper opioid prescribingand appropriate changes to patient care after unex-pected UDM results are outside the scope of this con-sensus report but are discussed in other guidelines[18202240] In brief options to address unexpectedUDM results include open and nonjudgmental discus-sions with patients additional confirmation testing in-creased monitoring a switch to a nonopioid painmedication or referral for treatment of an opioid usedisorder [18202240]
Three studies from the Philadelphia VA Medical Center in-vestigated how UDM results affected provider behavior[119146147] additional research to determine how UDMresults should influence patientsrsquo therapy is warranted Inthe absence of this information a follow-up consensusmeeting to evaluate expert opinion was suggested
Conclusions
In summary the expert panel made the following rec-ommendations regarding UDM (Figure 2)
1 Use definitive UDM testing (eg with GC-MS LC-MS or LC-MSMS) as the most clinically appropriatemethod for assessing baseline opioid use and opioidmisuse in most patients with chronic pain being con-sidered for opioids as well as for ongoing monitoringof patients receiving opioids for chronic pain unlesspresumptive testing is required by institutional orpayer policies A rational approach to choosing themost relevant analytes for UDM testing is proposedand should be documented by the clinician
2 To guide UDM frequency assess and stratify patientsprescribed opioid therapy for chronic pain with thefollowing strategies
bull perform a physical examination and obtain relevantpatient history for eventsdiagnoses and behaviorsthat have been shown to predict opioid misuseand opioid use disorder (eg history of substanceuse disorders psychiatric conditions sexual abuse)including information from previous providers forpatients transferring care
bull use validated tools to assess risk for aberrantmedication-taking behavior opioid misuse opioiduse disorder and the potential for respiratory de-pressionoverdose
bull check PDMPs and previous UDM results whenavailable
3 Perform UDM at baseline in patients receiving opioidsfor chronic pain During ongoing monitoring performUDM at least annually for low-risk patients two ormore times per year for moderate-risk patients andthree or more times per year for high-risk patientsAdditional monitoring can be performed as frequently
as necessary according to clinical judgment (egworrisome patient behavior related to the prescribedmedication)
The recommendations in this consensus report are meantto provide practical advice on implementing rational UDMacross a broad range of clinical practices in a patient-centric manner Some clinicians may not have access toappropriate resources to perform routine definitive UDMor to refer patients to pain specialists alternatives are pro-vided in the expert panel discussion sections Higher-quality studies on patient outcomes with UDM areneeded As a next step a consensus recommendationinitiative similar to this one that discusses appropriate clini-cian actions in response to test results that are inconsis-tent with prescribed therapy is warranted

are just one part of a comprehensive patient evaluation[2040]
Relevant Literature
Several tools for predicting and determining current risk ofaberrant medication-taking behaviors (eg lost prescrip-tion request for early refill) opioid misuse and opioid usedisorder are reported in the literature [96ndash99] In a painclinicndashbased study a semistructured clinical interview byan addiction psychologist was more sensitive than theORT Pain Medication Questionnaire and SOAPP-R atpredicting aberrant drug-related behavior [98] TheSOAPP-R showed the highest sensitivity of these self-report measures but may overestimate risk [98]
The use of external information (eg PDMPs) can alsoimprove patient management [100] In a university-based multidisciplinary pain management center misuseand diversion were detected more frequently by addingUDM andor a PDMP check to a baseline strategy ofcomparing patient reports and review of medicalrecords [101] However a systematic review of primarycare pain clinic and Veterans Administration (VA)Medical Center settings concluded that no single proce-dure or set of variables was sufficient to identify patientswith chronic pain who are at risk for opioid misuse orharmful substance use [97]
Expert Panel Discussion
The expert panelists suggest that patients be assessedfor risk of aberrant medication-taking behavior misuseand opioid use disorder to determine the frequency ofUDM A high-dose cutoff alone (eg 120-mg morphineequivalent dose per day [22]) was perceived as being in-adequate for identifying high-risk patients because highdoses may be appropriate to accommodate develop-ment of tolerance in specific patients [192187] In addi-tion patients predisposed to misuse may be at risk ofopioid use disorder or unsafe use even with low tomoderate doses
No specific risk assessment tool or behavioral assess-ment is recommended by panelists Clinicians are en-couraged to choose one or more of the many availabletools that match their preferences and can be incorpo-rated into their electronic medical records and workflow Understanding why specific factors predict risk ismore important than knowledge of the risk assessmenttools themselves (Figure 3 [1997102ndash107]) Risk strati-fication is not static and regular reevaluation of patientcircumstances (eg loss of a job divorce) is recom-mended An unexpected UDM result increases apatientrsquos risk of misuse and opioid use disorder neces-sitates more frequent testing and prompts reconsidera-tion of whether to modify opioid therapy or refer thepatient to a pain or addiction specialist
A comprehensive evaluation to assess the presence orrisk of misuse and opioid use disorder includes ques-tions about patientsrsquo history of substance use disordersand current clinical characteristics (eg from a physicalexamination) input from patientsrsquo family members andother health care providers (eg psychiatrists previouspain specialists) and pill counts Behaviors that may in-dicate increased likelihood of misuse or opioid use dis-order include requests for early refills [108]unauthorized dose escalations [109] and use of anotherindividualrsquos medication [109] Substance use disorder isgenerally associated with one or more of the four ldquoCsrdquo(ie impaired Control over use Compulsive useContinued use despite harm and Craving) [110]
A few simple questions (eg single-item screeningquestions [SISQs] for alcohol and drug use [93111]) fol-lowed by a discussion with patients is an efficient wayfor clinicians to incorporate risk assessment into theirpractice Reviewing a patientrsquos history of controlled sub-stance prescriptions in the PDMP is another method forassessing potential opioid misuse or substance use dis-order Clinicians should be aware of their statersquos regula-tions recommendations and resources regardingPDMPs [112] All states have or are planning to imple-ment a PDMP but reporting times vary and not everyprovider is required to participate in PDMPs in all states[112ndash114] The Comprehensive Addiction and RecoveryAct of 2016 is intended to improve the efficiency ofthese programs to track prescription drug use and helpprevent inappropriate use [115] Despite their inconsis-tencies PDMPs (when available) have become standardof care as part of patient risk evaluation WhetherPDMP data will predict aberrant behaviors or other ad-verse outcomes is not yet known and represents a gapin the science and an unmet need
Question 3 How Often Should UDM Occur in Patientswith Low Medium and High Risk for Opioid Misuseor Opioid Use Disorder
Expert Panel Recommendation
Perform UDM at baseline in patients prescribed opioidsfor chronic pain During ongoing monitoring performUDM at least annually for low-risk patients two or moretimes per year for moderate-risk patients and three ormore times per year for high-risk patients Additionalmonitoring can be performed at any risk level as fre-quently as necessary according to clinical judgment
Existing Guidelines
Recent guidelines recommend UDM at least annually forall patients regardless of risk [18] every six months totwo years for patients at low risk for opioid misuse oropioid use disorder [202240] one to three times peryear for moderate-risk patients [2022] and at least twoto four times per year for high-risk patients [202240]

The CDC Guideline for Prescribing Opioids for ChronicPain does not recommend tailoring the monitoringschedule according to risk because tools that predictharmful use lack sufficient accuracy [18] Several guide-lines [182122] suggest periodic UDM testing duringscheduled visits truly random testing outside of sched-uled clinic visits may not be feasible in many settings(eg primary care) or appropriate for all patients [18]
Relevant Literature
The identified studies related to UDM frequency do notdifferentiate strategies for low- moderate- and high-risklevels Nevertheless clinical trials assessing the effectsof UDM on outcomes are particularly relevant to deci-sions regarding frequency of monitoring (SupplementaryTable 1) Adherence to prescribed opioids is higher withmore frequent UDM according to a retrospective analy-sis of patients with chronic pain in private practices[116] In two prospective trials at an interventional painmanagement practice adherence monitoring that in-cluded random UDM was associated with reductions inindicators of opioid misuse (determined via periodicchart review UDM pill counts and verification of infor-mation with treating clinicians and pharmacies) [24] andillicit drug use (determined via UDM) [117] In anotherstudy a comprehensive risk reduction strategy includ-ing UDM led to decreased pill confiscations by law en-forcement agents and improved primary care providersrsquoperceptions of the overall quality of pain management[118] A structured program designed to support pri-mary care providers with chronic pain management ledto a greater-than-two-fold increase in UDM 22 months
after initiation of the program which was associatedwith a 727 relative decrease in total emergency de-partment (ED) visits and a 596 relative decrease inunscheduled primary care provider visits per patient onaverage [119]
The main negative clinical consequence of UDMreported in the literature was a lower likelihood ofpatients attending a second visit at an urban academicpain clinic after urine testing was used in the first officevisit [120] Individuals with positive test results for an il-licit substance were less likely to attend the second visitthan those with a negative result [120] Although thisstudy suggests that UDM at first visit may hinderpatient-clinician trust patient response to UDM mayvary by clinical setting by how the rationale for UDM isexplained to the patient and by the degree to whichUDM becomes routine in clinical practice
Many studies showed significant benefits of UDM how-ever a few did not No association between UDM and all-cause mortality was found in VA patients [121] althoughan association was not necessarily expected in this sam-ple of patients with a high burden of comorbiditiesAnother study conducted in a large health care systemshowed that an opioid risk reduction initiative (includingrecommendations on UDM) increased use of UDM with-out affecting rates of unexpected results (eg negative forprescribed opioids or positive for cannabis) [122]
Several studies and surveys of physicians (eg pain andaddiction specialists) nurses PAs and other health careprofessionals mainly from pain practices and academiccenters have assessed the frequency of UDM during
Risk Factors for Opioid

opioid therapy for chronic pain [296580123124]which provides context for recommendations on fre-quency Patients with chronic pain received an averageof 34 UDM tests per year according to a 2007 study ina Kentucky private pain practice [80] The frequency ofUDM testing increased by an average of 34 yearlyfrom 2005 to 2008 in a clinical laboratory serving a largeacademic center [123] Surveys indicated that individualpain and addiction experts differed in their frequency ofUDM use from testing at every office visit to yearly[2965] although most preferred random testing[65124] As a caveat these surveys did not focus onprimary care settings
Expert Panel Discussion
The expert panel did not specify how the relative riskcategories should be determined aside from suggestingseveral potential risk assessment tools and strategies(see the Question 2 section) Baseline UDM testing is tobe performed either before initiation of opioid therapyor for those continuing opioid therapy from another pro-vider within three months of the first office visit If thepatient received UDM testing from another providerwithin the previous year and the results were consistentwith prescribed opioid therapy no immediate retestingmay be needed to continue therapy
Regular UDM is recommended even in low-risk patientsbecause their circumstancesbehaviors can change overthe course of therapy Patients at especially low risk(eg receiving low-dose as-needed opioids) mayrequire infrequent UDM (eg every two years) Moderate-risk patients may become higher or lower risk dependingon their environment and stressors intense monitoring isusually not required in these patients but periodic reevalu-ation of their situationsrisk factors is appropriate
High-risk patients require more frequent individualizedUDM testing than those at low or moderate risk al-though the evidence supporting the effectiveness of in-tense monitoring is weak Most primary care providerscan best care for high-risk patients by referring them toa pain and addiction specialist when available Primarycare clinicians who are trained in chronic pain manage-ment utilize UDM are experienced in interpreting UDMresults and have access to consultant toxicologists maybe able to appropriately care for high-risk patientsandor comanage them with a pain specialist Currentguidelines for UDM in patients with substance usedisorder recommend use of personalized testingregimens [28]
Additional Expert Panel Recommendations andDiscussion
UDM Rationale
Clinicians are encouraged to include information relatedto UDM in patient-provider agreements and explain to
patients that the primary goals of UDM are to improvethe safety and effectiveness of therapy by monitoringadherence Furthermore UDM is strongly recommendedas part of a universal precautions approach [125]Consistent UDM results provide objective data to sup-port decision-making during chronic opioid therapy
UDM Process
The panelists recommend that clinicians discuss theUDM process openly with patients as they do with allother clinical testing and document the time of lastmedication use before urine collection Unexpectedresults may be caused by laboratory errors (eg mislab-eling) or by sample adulteration including substitution ofsynthetic or another individualrsquos urine Signs of tamper-ing include temperature outside the normal range of90 F to 100 F within four minutes of sample collectionpH outside the normal range of 45 to 80 low creati-nine concentration (ie 20 mgdL) low specific gravity(ie 1003) presence of adulterants or detection ofparent drug without metabolites [28] Variation in metab-olite levels may also result from pharmacogenetic anom-alies or drug-drug interactions affecting drugmetabolism [28126]
Strategies to prevent sample tampering depend on theclinical setting and can include observed collection(viewed as overly invasive of a patientrsquos privacy) achain-of-custody protocol (ie documentation for han-dling of the specimen) and a truly random collection(ie a protocol to notify the patients of required testingwithin a set period) [28] Although observed urine sam-ple collection at pain clinics has been recommended[83] this practice and chain-of-custody protocols aretypically not followed Despite risk-mitigation strategiesdedicated individuals can still manipulate their UDMsamples or consume prescribed medication before of-fice visits to conceal misuse or diversion Patients withan opioid use disorder may not be able to control theirdrug use to avoid unexpected UDM results despitescheduled collection
Alcohol Screening
For patients with a substance use disorder alcohol maybe problematic and prohibited in any amount for otherpatients with chronic pain only high-risk alcohol use(eg binge drinking) is a concern Many opioids includeblack box warnings about the concurrent use of alcoholbecause of the potential for fatal overdose [127] Onereviewed guideline recommends screening for alcoholwith UDM in patients with chronic pain [22] ethyl glucu-ronide ethyl sulfate or ethanol in UDM indicates alcoholuse [128] As a caveat immunoassay and definitiveUDM may not differentiate between alcoholic beveragesand alcohol-containing medications mouthwashes andhand sanitizers [28] Instead of UDM the panelists

recommend the SISQ ldquoHow many times in the past yearhave you had (five or more drinks [men] four or moredrinks [women]) in a dayrdquo from the National Institute onAlcohol Abuse and Alcoholism [111] to identify un-healthy alcohol use as this question is simple to admin-ister and is validated [129] In primary care settings thesensitivity of the alcohol SISQ for identifying alcohol usedisorder is 88 and the specificity is 84 [130]
Cannabis Screening
Practices for cannabis screening vary [131] individualprescribers can decide whether detecting cannabis byUDM is appropriate by consulting local laws [132133]and common practice as well as by considering theadvantagesdisadvantages discussed below At the timeof this publication cannabis is federally illegal (ie clas-sified by the US Drug Enforcement Administration asSchedule 1 under the Controlled Substances Act) butseveral states have passed legislation to decriminalize itfor medical andor recreational use [131ndash134] The CDCGuideline for Prescribing Opioids for Chronic Pain indi-cates that the clinical implications of a positive UDM re-sult for cannabis are uncertain [18] the VAUSDepartment of Defense guidelines estimate the length oftime it can be detected in urine [21] and theWashington State guidelines suggest implementing anoffice policy for patients who use cannabis [22] Theseguidelines [182122] and this consensus report do notprovide formal graded recommendations for or againstUDM screening for cannabis or for interpretation of theresults
Clinicians who avoid cannabis testing may miss criticalinformation that could inform patient monitoring and im-prove safety Data from Colorado indicate increased EDvisits hospitalizations and proportions of fatal motor ve-hicle accidents related to cannabis intoxication after de-criminalization [134ndash136] Illegal use of cannabis is amarker for opioid misuse and substance use disorders[137] and a rationale to classify a patient as high riskAnother concern is that patients may divert prescriptionopioids to purchase cannabis
If clinicians choose to assess patientsrsquo nonprescriptioncannabinoid use there is a validated SISQ for drugs in-cluding cannabis (ie ldquoHow many times in the past yearhave you used an illegal drug or used a prescriptionmedication for nonmedical reasonsrdquo) [93] with a sensi-tivity of 97 and a specificity of 79 for substance usedisorders in primary care settings [130] Although somemetabolites of synthetic cannabinoids (eg spice) canbe analyzed with specialized immunoassayschromatographyspectrometry-based assays are betterfor assessing the many emerging synthetic cannabi-noids and their metabolites [138]
A subject of ongoing debate is whether co-administration of opioids and cannabis (used
recreationally or medically) is safe or reasonable for clini-cians to allow Cannabis is increasingly accepted formedical purposes especially for cancer pain syn-dromes However allowing patients with chronic pain touse cannabis is a potential liability for clinicians (includ-ing pharmacists) regardless of the drugrsquos legal status intheir state [139] The safety of cannabis for patients withchronic pain is not clearly established [140] and little isknown regarding the safety of concurrent use withopioids apart from the potential opioid-sparing effects ofcannabis [141] The composition and dose of the manyactive components in cannabis vary widely [133142]which leads to variable toxicity [143] and complicatessafety studies Cannabinoids may inhibit cytochromeP450 2D6 [144] (involved in opioid metabolism [145])and therefore affect both the efficacy of opioids and theability to detect metabolites in UDM The panelists pro-posed that a single clinician be responsible for manag-ing both opioid and cannabis use in states where thedrug has been decriminalized and the benefits of con-current use outweigh the risks
Interpreting UDM Results and Implications forChanging Clinical Practice
The panelists believe that clinicians should follow manu-facturer instructions for specific POC UDM tests and di-rect any questions about interpreting results to anexpert in toxicology or clinical pathology Laboratoriesperforming UDM have a responsibility to provide cleartest results answer questions and offer support on clin-ical decisions When clinicians are confronted with un-expected results potential causes for false-positive andfalse-negative results (eg quinolone antibiotics tolme-tin Figure 1) are important to investigate A summary ofcommunications and discussions about results with thelaboratory and other experts can be included in themedical record to document the medical necessity oftesting and related clinical decision-making
Communications with patients about the purpose andresults of UDM should be nonjudgmental and nonpuni-tive and should focus on safety and risks associatedwith misuse and opioid use disorder To avoid unex-pected results open discussion with patients is recom-mended and may include asking questions such as ldquoIfwe test you today what will we find in your urine Willthere be any surprisesrdquo Development of a plan to ad-dress UDM results that are inconsistent with therapy issuggested to mitigate safety risks for patients and po-tential regulatory board sanctions for clinicians Of noteUDM results that are consistent with prescribed opioidscannot differentiate among appropriate use occasionaluse or misuse and opioid use disorder negative UDMresults for prescribed opioids cannot distinguishbetween infrequent need for medicine overuse and run-ning out falsification of the urine sample and diversionResults of UDM are only part of the clinical information

(eg including patient history) that must be consideredbefore a treatment plan is changed
Detailed recommendations on proper opioid prescribingand appropriate changes to patient care after unex-pected UDM results are outside the scope of this con-sensus report but are discussed in other guidelines[18202240] In brief options to address unexpectedUDM results include open and nonjudgmental discus-sions with patients additional confirmation testing in-creased monitoring a switch to a nonopioid painmedication or referral for treatment of an opioid usedisorder [18202240]
Three studies from the Philadelphia VA Medical Center in-vestigated how UDM results affected provider behavior[119146147] additional research to determine how UDMresults should influence patientsrsquo therapy is warranted Inthe absence of this information a follow-up consensusmeeting to evaluate expert opinion was suggested
Conclusions
In summary the expert panel made the following rec-ommendations regarding UDM (Figure 2)
1 Use definitive UDM testing (eg with GC-MS LC-MS or LC-MSMS) as the most clinically appropriatemethod for assessing baseline opioid use and opioidmisuse in most patients with chronic pain being con-sidered for opioids as well as for ongoing monitoringof patients receiving opioids for chronic pain unlesspresumptive testing is required by institutional orpayer policies A rational approach to choosing themost relevant analytes for UDM testing is proposedand should be documented by the clinician
2 To guide UDM frequency assess and stratify patientsprescribed opioid therapy for chronic pain with thefollowing strategies
bull perform a physical examination and obtain relevantpatient history for eventsdiagnoses and behaviorsthat have been shown to predict opioid misuseand opioid use disorder (eg history of substanceuse disorders psychiatric conditions sexual abuse)including information from previous providers forpatients transferring care
bull use validated tools to assess risk for aberrantmedication-taking behavior opioid misuse opioiduse disorder and the potential for respiratory de-pressionoverdose
bull check PDMPs and previous UDM results whenavailable
3 Perform UDM at baseline in patients receiving opioidsfor chronic pain During ongoing monitoring performUDM at least annually for low-risk patients two ormore times per year for moderate-risk patients andthree or more times per year for high-risk patientsAdditional monitoring can be performed as frequently
as necessary according to clinical judgment (egworrisome patient behavior related to the prescribedmedication)
The recommendations in this consensus report are meantto provide practical advice on implementing rational UDMacross a broad range of clinical practices in a patient-centric manner Some clinicians may not have access toappropriate resources to perform routine definitive UDMor to refer patients to pain specialists alternatives are pro-vided in the expert panel discussion sections Higher-quality studies on patient outcomes with UDM areneeded As a next step a consensus recommendationinitiative similar to this one that discusses appropriate clini-cian actions in response to test results that are inconsis-tent with prescribed therapy is warranted

The CDC Guideline for Prescribing Opioids for ChronicPain does not recommend tailoring the monitoringschedule according to risk because tools that predictharmful use lack sufficient accuracy [18] Several guide-lines [182122] suggest periodic UDM testing duringscheduled visits truly random testing outside of sched-uled clinic visits may not be feasible in many settings(eg primary care) or appropriate for all patients [18]
Relevant Literature
The identified studies related to UDM frequency do notdifferentiate strategies for low- moderate- and high-risklevels Nevertheless clinical trials assessing the effectsof UDM on outcomes are particularly relevant to deci-sions regarding frequency of monitoring (SupplementaryTable 1) Adherence to prescribed opioids is higher withmore frequent UDM according to a retrospective analy-sis of patients with chronic pain in private practices[116] In two prospective trials at an interventional painmanagement practice adherence monitoring that in-cluded random UDM was associated with reductions inindicators of opioid misuse (determined via periodicchart review UDM pill counts and verification of infor-mation with treating clinicians and pharmacies) [24] andillicit drug use (determined via UDM) [117] In anotherstudy a comprehensive risk reduction strategy includ-ing UDM led to decreased pill confiscations by law en-forcement agents and improved primary care providersrsquoperceptions of the overall quality of pain management[118] A structured program designed to support pri-mary care providers with chronic pain management ledto a greater-than-two-fold increase in UDM 22 months
after initiation of the program which was associatedwith a 727 relative decrease in total emergency de-partment (ED) visits and a 596 relative decrease inunscheduled primary care provider visits per patient onaverage [119]
The main negative clinical consequence of UDMreported in the literature was a lower likelihood ofpatients attending a second visit at an urban academicpain clinic after urine testing was used in the first officevisit [120] Individuals with positive test results for an il-licit substance were less likely to attend the second visitthan those with a negative result [120] Although thisstudy suggests that UDM at first visit may hinderpatient-clinician trust patient response to UDM mayvary by clinical setting by how the rationale for UDM isexplained to the patient and by the degree to whichUDM becomes routine in clinical practice
Many studies showed significant benefits of UDM how-ever a few did not No association between UDM and all-cause mortality was found in VA patients [121] althoughan association was not necessarily expected in this sam-ple of patients with a high burden of comorbiditiesAnother study conducted in a large health care systemshowed that an opioid risk reduction initiative (includingrecommendations on UDM) increased use of UDM with-out affecting rates of unexpected results (eg negative forprescribed opioids or positive for cannabis) [122]
Several studies and surveys of physicians (eg pain andaddiction specialists) nurses PAs and other health careprofessionals mainly from pain practices and academiccenters have assessed the frequency of UDM during

opioid therapy for chronic pain [296580123124]which provides context for recommendations on fre-quency Patients with chronic pain received an averageof 34 UDM tests per year according to a 2007 study ina Kentucky private pain practice [80] The frequency ofUDM testing increased by an average of 34 yearlyfrom 2005 to 2008 in a clinical laboratory serving a largeacademic center [123] Surveys indicated that individualpain and addiction experts differed in their frequency ofUDM use from testing at every office visit to yearly[2965] although most preferred random testing[65124] As a caveat these surveys did not focus onprimary care settings
Expert Panel Discussion
The expert panel did not specify how the relative riskcategories should be determined aside from suggestingseveral potential risk assessment tools and strategies(see the Question 2 section) Baseline UDM testing is tobe performed either before initiation of opioid therapyor for those continuing opioid therapy from another pro-vider within three months of the first office visit If thepatient received UDM testing from another providerwithin the previous year and the results were consistentwith prescribed opioid therapy no immediate retestingmay be needed to continue therapy
Regular UDM is recommended even in low-risk patientsbecause their circumstancesbehaviors can change overthe course of therapy Patients at especially low risk(eg receiving low-dose as-needed opioids) mayrequire infrequent UDM (eg every two years) Moderate-risk patients may become higher or lower risk dependingon their environment and stressors intense monitoring isusually not required in these patients but periodic reevalu-ation of their situationsrisk factors is appropriate
High-risk patients require more frequent individualizedUDM testing than those at low or moderate risk al-though the evidence supporting the effectiveness of in-tense monitoring is weak Most primary care providerscan best care for high-risk patients by referring them toa pain and addiction specialist when available Primarycare clinicians who are trained in chronic pain manage-ment utilize UDM are experienced in interpreting UDMresults and have access to consultant toxicologists maybe able to appropriately care for high-risk patientsandor comanage them with a pain specialist Currentguidelines for UDM in patients with substance usedisorder recommend use of personalized testingregimens [28]
Additional Expert Panel Recommendations andDiscussion
UDM Rationale
Clinicians are encouraged to include information relatedto UDM in patient-provider agreements and explain to
patients that the primary goals of UDM are to improvethe safety and effectiveness of therapy by monitoringadherence Furthermore UDM is strongly recommendedas part of a universal precautions approach [125]Consistent UDM results provide objective data to sup-port decision-making during chronic opioid therapy
UDM Process
The panelists recommend that clinicians discuss theUDM process openly with patients as they do with allother clinical testing and document the time of lastmedication use before urine collection Unexpectedresults may be caused by laboratory errors (eg mislab-eling) or by sample adulteration including substitution ofsynthetic or another individualrsquos urine Signs of tamper-ing include temperature outside the normal range of90 F to 100 F within four minutes of sample collectionpH outside the normal range of 45 to 80 low creati-nine concentration (ie 20 mgdL) low specific gravity(ie 1003) presence of adulterants or detection ofparent drug without metabolites [28] Variation in metab-olite levels may also result from pharmacogenetic anom-alies or drug-drug interactions affecting drugmetabolism [28126]
Strategies to prevent sample tampering depend on theclinical setting and can include observed collection(viewed as overly invasive of a patientrsquos privacy) achain-of-custody protocol (ie documentation for han-dling of the specimen) and a truly random collection(ie a protocol to notify the patients of required testingwithin a set period) [28] Although observed urine sam-ple collection at pain clinics has been recommended[83] this practice and chain-of-custody protocols aretypically not followed Despite risk-mitigation strategiesdedicated individuals can still manipulate their UDMsamples or consume prescribed medication before of-fice visits to conceal misuse or diversion Patients withan opioid use disorder may not be able to control theirdrug use to avoid unexpected UDM results despitescheduled collection
Alcohol Screening
For patients with a substance use disorder alcohol maybe problematic and prohibited in any amount for otherpatients with chronic pain only high-risk alcohol use(eg binge drinking) is a concern Many opioids includeblack box warnings about the concurrent use of alcoholbecause of the potential for fatal overdose [127] Onereviewed guideline recommends screening for alcoholwith UDM in patients with chronic pain [22] ethyl glucu-ronide ethyl sulfate or ethanol in UDM indicates alcoholuse [128] As a caveat immunoassay and definitiveUDM may not differentiate between alcoholic beveragesand alcohol-containing medications mouthwashes andhand sanitizers [28] Instead of UDM the panelists

recommend the SISQ ldquoHow many times in the past yearhave you had (five or more drinks [men] four or moredrinks [women]) in a dayrdquo from the National Institute onAlcohol Abuse and Alcoholism [111] to identify un-healthy alcohol use as this question is simple to admin-ister and is validated [129] In primary care settings thesensitivity of the alcohol SISQ for identifying alcohol usedisorder is 88 and the specificity is 84 [130]
Cannabis Screening
Practices for cannabis screening vary [131] individualprescribers can decide whether detecting cannabis byUDM is appropriate by consulting local laws [132133]and common practice as well as by considering theadvantagesdisadvantages discussed below At the timeof this publication cannabis is federally illegal (ie clas-sified by the US Drug Enforcement Administration asSchedule 1 under the Controlled Substances Act) butseveral states have passed legislation to decriminalize itfor medical andor recreational use [131ndash134] The CDCGuideline for Prescribing Opioids for Chronic Pain indi-cates that the clinical implications of a positive UDM re-sult for cannabis are uncertain [18] the VAUSDepartment of Defense guidelines estimate the length oftime it can be detected in urine [21] and theWashington State guidelines suggest implementing anoffice policy for patients who use cannabis [22] Theseguidelines [182122] and this consensus report do notprovide formal graded recommendations for or againstUDM screening for cannabis or for interpretation of theresults
Clinicians who avoid cannabis testing may miss criticalinformation that could inform patient monitoring and im-prove safety Data from Colorado indicate increased EDvisits hospitalizations and proportions of fatal motor ve-hicle accidents related to cannabis intoxication after de-criminalization [134ndash136] Illegal use of cannabis is amarker for opioid misuse and substance use disorders[137] and a rationale to classify a patient as high riskAnother concern is that patients may divert prescriptionopioids to purchase cannabis
If clinicians choose to assess patientsrsquo nonprescriptioncannabinoid use there is a validated SISQ for drugs in-cluding cannabis (ie ldquoHow many times in the past yearhave you used an illegal drug or used a prescriptionmedication for nonmedical reasonsrdquo) [93] with a sensi-tivity of 97 and a specificity of 79 for substance usedisorders in primary care settings [130] Although somemetabolites of synthetic cannabinoids (eg spice) canbe analyzed with specialized immunoassayschromatographyspectrometry-based assays are betterfor assessing the many emerging synthetic cannabi-noids and their metabolites [138]
A subject of ongoing debate is whether co-administration of opioids and cannabis (used
recreationally or medically) is safe or reasonable for clini-cians to allow Cannabis is increasingly accepted formedical purposes especially for cancer pain syn-dromes However allowing patients with chronic pain touse cannabis is a potential liability for clinicians (includ-ing pharmacists) regardless of the drugrsquos legal status intheir state [139] The safety of cannabis for patients withchronic pain is not clearly established [140] and little isknown regarding the safety of concurrent use withopioids apart from the potential opioid-sparing effects ofcannabis [141] The composition and dose of the manyactive components in cannabis vary widely [133142]which leads to variable toxicity [143] and complicatessafety studies Cannabinoids may inhibit cytochromeP450 2D6 [144] (involved in opioid metabolism [145])and therefore affect both the efficacy of opioids and theability to detect metabolites in UDM The panelists pro-posed that a single clinician be responsible for manag-ing both opioid and cannabis use in states where thedrug has been decriminalized and the benefits of con-current use outweigh the risks
Interpreting UDM Results and Implications forChanging Clinical Practice
The panelists believe that clinicians should follow manu-facturer instructions for specific POC UDM tests and di-rect any questions about interpreting results to anexpert in toxicology or clinical pathology Laboratoriesperforming UDM have a responsibility to provide cleartest results answer questions and offer support on clin-ical decisions When clinicians are confronted with un-expected results potential causes for false-positive andfalse-negative results (eg quinolone antibiotics tolme-tin Figure 1) are important to investigate A summary ofcommunications and discussions about results with thelaboratory and other experts can be included in themedical record to document the medical necessity oftesting and related clinical decision-making
Communications with patients about the purpose andresults of UDM should be nonjudgmental and nonpuni-tive and should focus on safety and risks associatedwith misuse and opioid use disorder To avoid unex-pected results open discussion with patients is recom-mended and may include asking questions such as ldquoIfwe test you today what will we find in your urine Willthere be any surprisesrdquo Development of a plan to ad-dress UDM results that are inconsistent with therapy issuggested to mitigate safety risks for patients and po-tential regulatory board sanctions for clinicians Of noteUDM results that are consistent with prescribed opioidscannot differentiate among appropriate use occasionaluse or misuse and opioid use disorder negative UDMresults for prescribed opioids cannot distinguishbetween infrequent need for medicine overuse and run-ning out falsification of the urine sample and diversionResults of UDM are only part of the clinical information

(eg including patient history) that must be consideredbefore a treatment plan is changed
Detailed recommendations on proper opioid prescribingand appropriate changes to patient care after unex-pected UDM results are outside the scope of this con-sensus report but are discussed in other guidelines[18202240] In brief options to address unexpectedUDM results include open and nonjudgmental discus-sions with patients additional confirmation testing in-creased monitoring a switch to a nonopioid painmedication or referral for treatment of an opioid usedisorder [18202240]
Three studies from the Philadelphia VA Medical Center in-vestigated how UDM results affected provider behavior[119146147] additional research to determine how UDMresults should influence patientsrsquo therapy is warranted Inthe absence of this information a follow-up consensusmeeting to evaluate expert opinion was suggested
Conclusions
In summary the expert panel made the following rec-ommendations regarding UDM (Figure 2)
1 Use definitive UDM testing (eg with GC-MS LC-MS or LC-MSMS) as the most clinically appropriatemethod for assessing baseline opioid use and opioidmisuse in most patients with chronic pain being con-sidered for opioids as well as for ongoing monitoringof patients receiving opioids for chronic pain unlesspresumptive testing is required by institutional orpayer policies A rational approach to choosing themost relevant analytes for UDM testing is proposedand should be documented by the clinician
2 To guide UDM frequency assess and stratify patientsprescribed opioid therapy for chronic pain with thefollowing strategies
bull perform a physical examination and obtain relevantpatient history for eventsdiagnoses and behaviorsthat have been shown to predict opioid misuseand opioid use disorder (eg history of substanceuse disorders psychiatric conditions sexual abuse)including information from previous providers forpatients transferring care
bull use validated tools to assess risk for aberrantmedication-taking behavior opioid misuse opioiduse disorder and the potential for respiratory de-pressionoverdose
bull check PDMPs and previous UDM results whenavailable
3 Perform UDM at baseline in patients receiving opioidsfor chronic pain During ongoing monitoring performUDM at least annually for low-risk patients two ormore times per year for moderate-risk patients andthree or more times per year for high-risk patientsAdditional monitoring can be performed as frequently
as necessary according to clinical judgment (egworrisome patient behavior related to the prescribedmedication)
The recommendations in this consensus report are meantto provide practical advice on implementing rational UDMacross a broad range of clinical practices in a patient-centric manner Some clinicians may not have access toappropriate resources to perform routine definitive UDMor to refer patients to pain specialists alternatives are pro-vided in the expert panel discussion sections Higher-quality studies on patient outcomes with UDM areneeded As a next step a consensus recommendationinitiative similar to this one that discusses appropriate clini-cian actions in response to test results that are inconsis-tent with prescribed therapy is warranted

opioid therapy for chronic pain [296580123124]which provides context for recommendations on fre-quency Patients with chronic pain received an averageof 34 UDM tests per year according to a 2007 study ina Kentucky private pain practice [80] The frequency ofUDM testing increased by an average of 34 yearlyfrom 2005 to 2008 in a clinical laboratory serving a largeacademic center [123] Surveys indicated that individualpain and addiction experts differed in their frequency ofUDM use from testing at every office visit to yearly[2965] although most preferred random testing[65124] As a caveat these surveys did not focus onprimary care settings
Expert Panel Discussion
The expert panel did not specify how the relative riskcategories should be determined aside from suggestingseveral potential risk assessment tools and strategies(see the Question 2 section) Baseline UDM testing is tobe performed either before initiation of opioid therapyor for those continuing opioid therapy from another pro-vider within three months of the first office visit If thepatient received UDM testing from another providerwithin the previous year and the results were consistentwith prescribed opioid therapy no immediate retestingmay be needed to continue therapy
Regular UDM is recommended even in low-risk patientsbecause their circumstancesbehaviors can change overthe course of therapy Patients at especially low risk(eg receiving low-dose as-needed opioids) mayrequire infrequent UDM (eg every two years) Moderate-risk patients may become higher or lower risk dependingon their environment and stressors intense monitoring isusually not required in these patients but periodic reevalu-ation of their situationsrisk factors is appropriate
High-risk patients require more frequent individualizedUDM testing than those at low or moderate risk al-though the evidence supporting the effectiveness of in-tense monitoring is weak Most primary care providerscan best care for high-risk patients by referring them toa pain and addiction specialist when available Primarycare clinicians who are trained in chronic pain manage-ment utilize UDM are experienced in interpreting UDMresults and have access to consultant toxicologists maybe able to appropriately care for high-risk patientsandor comanage them with a pain specialist Currentguidelines for UDM in patients with substance usedisorder recommend use of personalized testingregimens [28]
Additional Expert Panel Recommendations andDiscussion
UDM Rationale
Clinicians are encouraged to include information relatedto UDM in patient-provider agreements and explain to
patients that the primary goals of UDM are to improvethe safety and effectiveness of therapy by monitoringadherence Furthermore UDM is strongly recommendedas part of a universal precautions approach [125]Consistent UDM results provide objective data to sup-port decision-making during chronic opioid therapy
UDM Process
The panelists recommend that clinicians discuss theUDM process openly with patients as they do with allother clinical testing and document the time of lastmedication use before urine collection Unexpectedresults may be caused by laboratory errors (eg mislab-eling) or by sample adulteration including substitution ofsynthetic or another individualrsquos urine Signs of tamper-ing include temperature outside the normal range of90 F to 100 F within four minutes of sample collectionpH outside the normal range of 45 to 80 low creati-nine concentration (ie 20 mgdL) low specific gravity(ie 1003) presence of adulterants or detection ofparent drug without metabolites [28] Variation in metab-olite levels may also result from pharmacogenetic anom-alies or drug-drug interactions affecting drugmetabolism [28126]
Strategies to prevent sample tampering depend on theclinical setting and can include observed collection(viewed as overly invasive of a patientrsquos privacy) achain-of-custody protocol (ie documentation for han-dling of the specimen) and a truly random collection(ie a protocol to notify the patients of required testingwithin a set period) [28] Although observed urine sam-ple collection at pain clinics has been recommended[83] this practice and chain-of-custody protocols aretypically not followed Despite risk-mitigation strategiesdedicated individuals can still manipulate their UDMsamples or consume prescribed medication before of-fice visits to conceal misuse or diversion Patients withan opioid use disorder may not be able to control theirdrug use to avoid unexpected UDM results despitescheduled collection
Alcohol Screening
For patients with a substance use disorder alcohol maybe problematic and prohibited in any amount for otherpatients with chronic pain only high-risk alcohol use(eg binge drinking) is a concern Many opioids includeblack box warnings about the concurrent use of alcoholbecause of the potential for fatal overdose [127] Onereviewed guideline recommends screening for alcoholwith UDM in patients with chronic pain [22] ethyl glucu-ronide ethyl sulfate or ethanol in UDM indicates alcoholuse [128] As a caveat immunoassay and definitiveUDM may not differentiate between alcoholic beveragesand alcohol-containing medications mouthwashes andhand sanitizers [28] Instead of UDM the panelists

recommend the SISQ ldquoHow many times in the past yearhave you had (five or more drinks [men] four or moredrinks [women]) in a dayrdquo from the National Institute onAlcohol Abuse and Alcoholism [111] to identify un-healthy alcohol use as this question is simple to admin-ister and is validated [129] In primary care settings thesensitivity of the alcohol SISQ for identifying alcohol usedisorder is 88 and the specificity is 84 [130]
Cannabis Screening
Practices for cannabis screening vary [131] individualprescribers can decide whether detecting cannabis byUDM is appropriate by consulting local laws [132133]and common practice as well as by considering theadvantagesdisadvantages discussed below At the timeof this publication cannabis is federally illegal (ie clas-sified by the US Drug Enforcement Administration asSchedule 1 under the Controlled Substances Act) butseveral states have passed legislation to decriminalize itfor medical andor recreational use [131ndash134] The CDCGuideline for Prescribing Opioids for Chronic Pain indi-cates that the clinical implications of a positive UDM re-sult for cannabis are uncertain [18] the VAUSDepartment of Defense guidelines estimate the length oftime it can be detected in urine [21] and theWashington State guidelines suggest implementing anoffice policy for patients who use cannabis [22] Theseguidelines [182122] and this consensus report do notprovide formal graded recommendations for or againstUDM screening for cannabis or for interpretation of theresults
Clinicians who avoid cannabis testing may miss criticalinformation that could inform patient monitoring and im-prove safety Data from Colorado indicate increased EDvisits hospitalizations and proportions of fatal motor ve-hicle accidents related to cannabis intoxication after de-criminalization [134ndash136] Illegal use of cannabis is amarker for opioid misuse and substance use disorders[137] and a rationale to classify a patient as high riskAnother concern is that patients may divert prescriptionopioids to purchase cannabis
If clinicians choose to assess patientsrsquo nonprescriptioncannabinoid use there is a validated SISQ for drugs in-cluding cannabis (ie ldquoHow many times in the past yearhave you used an illegal drug or used a prescriptionmedication for nonmedical reasonsrdquo) [93] with a sensi-tivity of 97 and a specificity of 79 for substance usedisorders in primary care settings [130] Although somemetabolites of synthetic cannabinoids (eg spice) canbe analyzed with specialized immunoassayschromatographyspectrometry-based assays are betterfor assessing the many emerging synthetic cannabi-noids and their metabolites [138]
A subject of ongoing debate is whether co-administration of opioids and cannabis (used
recreationally or medically) is safe or reasonable for clini-cians to allow Cannabis is increasingly accepted formedical purposes especially for cancer pain syn-dromes However allowing patients with chronic pain touse cannabis is a potential liability for clinicians (includ-ing pharmacists) regardless of the drugrsquos legal status intheir state [139] The safety of cannabis for patients withchronic pain is not clearly established [140] and little isknown regarding the safety of concurrent use withopioids apart from the potential opioid-sparing effects ofcannabis [141] The composition and dose of the manyactive components in cannabis vary widely [133142]which leads to variable toxicity [143] and complicatessafety studies Cannabinoids may inhibit cytochromeP450 2D6 [144] (involved in opioid metabolism [145])and therefore affect both the efficacy of opioids and theability to detect metabolites in UDM The panelists pro-posed that a single clinician be responsible for manag-ing both opioid and cannabis use in states where thedrug has been decriminalized and the benefits of con-current use outweigh the risks
Interpreting UDM Results and Implications forChanging Clinical Practice
The panelists believe that clinicians should follow manu-facturer instructions for specific POC UDM tests and di-rect any questions about interpreting results to anexpert in toxicology or clinical pathology Laboratoriesperforming UDM have a responsibility to provide cleartest results answer questions and offer support on clin-ical decisions When clinicians are confronted with un-expected results potential causes for false-positive andfalse-negative results (eg quinolone antibiotics tolme-tin Figure 1) are important to investigate A summary ofcommunications and discussions about results with thelaboratory and other experts can be included in themedical record to document the medical necessity oftesting and related clinical decision-making
Communications with patients about the purpose andresults of UDM should be nonjudgmental and nonpuni-tive and should focus on safety and risks associatedwith misuse and opioid use disorder To avoid unex-pected results open discussion with patients is recom-mended and may include asking questions such as ldquoIfwe test you today what will we find in your urine Willthere be any surprisesrdquo Development of a plan to ad-dress UDM results that are inconsistent with therapy issuggested to mitigate safety risks for patients and po-tential regulatory board sanctions for clinicians Of noteUDM results that are consistent with prescribed opioidscannot differentiate among appropriate use occasionaluse or misuse and opioid use disorder negative UDMresults for prescribed opioids cannot distinguishbetween infrequent need for medicine overuse and run-ning out falsification of the urine sample and diversionResults of UDM are only part of the clinical information

(eg including patient history) that must be consideredbefore a treatment plan is changed
Detailed recommendations on proper opioid prescribingand appropriate changes to patient care after unex-pected UDM results are outside the scope of this con-sensus report but are discussed in other guidelines[18202240] In brief options to address unexpectedUDM results include open and nonjudgmental discus-sions with patients additional confirmation testing in-creased monitoring a switch to a nonopioid painmedication or referral for treatment of an opioid usedisorder [18202240]
Three studies from the Philadelphia VA Medical Center in-vestigated how UDM results affected provider behavior[119146147] additional research to determine how UDMresults should influence patientsrsquo therapy is warranted Inthe absence of this information a follow-up consensusmeeting to evaluate expert opinion was suggested
Conclusions
In summary the expert panel made the following rec-ommendations regarding UDM (Figure 2)
1 Use definitive UDM testing (eg with GC-MS LC-MS or LC-MSMS) as the most clinically appropriatemethod for assessing baseline opioid use and opioidmisuse in most patients with chronic pain being con-sidered for opioids as well as for ongoing monitoringof patients receiving opioids for chronic pain unlesspresumptive testing is required by institutional orpayer policies A rational approach to choosing themost relevant analytes for UDM testing is proposedand should be documented by the clinician
2 To guide UDM frequency assess and stratify patientsprescribed opioid therapy for chronic pain with thefollowing strategies
bull perform a physical examination and obtain relevantpatient history for eventsdiagnoses and behaviorsthat have been shown to predict opioid misuseand opioid use disorder (eg history of substanceuse disorders psychiatric conditions sexual abuse)including information from previous providers forpatients transferring care
bull use validated tools to assess risk for aberrantmedication-taking behavior opioid misuse opioiduse disorder and the potential for respiratory de-pressionoverdose
bull check PDMPs and previous UDM results whenavailable
3 Perform UDM at baseline in patients receiving opioidsfor chronic pain During ongoing monitoring performUDM at least annually for low-risk patients two ormore times per year for moderate-risk patients andthree or more times per year for high-risk patientsAdditional monitoring can be performed as frequently
as necessary according to clinical judgment (egworrisome patient behavior related to the prescribedmedication)
The recommendations in this consensus report are meantto provide practical advice on implementing rational UDMacross a broad range of clinical practices in a patient-centric manner Some clinicians may not have access toappropriate resources to perform routine definitive UDMor to refer patients to pain specialists alternatives are pro-vided in the expert panel discussion sections Higher-quality studies on patient outcomes with UDM areneeded As a next step a consensus recommendationinitiative similar to this one that discusses appropriate clini-cian actions in response to test results that are inconsis-tent with prescribed therapy is warranted

recommend the SISQ ldquoHow many times in the past yearhave you had (five or more drinks [men] four or moredrinks [women]) in a dayrdquo from the National Institute onAlcohol Abuse and Alcoholism [111] to identify un-healthy alcohol use as this question is simple to admin-ister and is validated [129] In primary care settings thesensitivity of the alcohol SISQ for identifying alcohol usedisorder is 88 and the specificity is 84 [130]
Cannabis Screening
Practices for cannabis screening vary [131] individualprescribers can decide whether detecting cannabis byUDM is appropriate by consulting local laws [132133]and common practice as well as by considering theadvantagesdisadvantages discussed below At the timeof this publication cannabis is federally illegal (ie clas-sified by the US Drug Enforcement Administration asSchedule 1 under the Controlled Substances Act) butseveral states have passed legislation to decriminalize itfor medical andor recreational use [131ndash134] The CDCGuideline for Prescribing Opioids for Chronic Pain indi-cates that the clinical implications of a positive UDM re-sult for cannabis are uncertain [18] the VAUSDepartment of Defense guidelines estimate the length oftime it can be detected in urine [21] and theWashington State guidelines suggest implementing anoffice policy for patients who use cannabis [22] Theseguidelines [182122] and this consensus report do notprovide formal graded recommendations for or againstUDM screening for cannabis or for interpretation of theresults
Clinicians who avoid cannabis testing may miss criticalinformation that could inform patient monitoring and im-prove safety Data from Colorado indicate increased EDvisits hospitalizations and proportions of fatal motor ve-hicle accidents related to cannabis intoxication after de-criminalization [134ndash136] Illegal use of cannabis is amarker for opioid misuse and substance use disorders[137] and a rationale to classify a patient as high riskAnother concern is that patients may divert prescriptionopioids to purchase cannabis
If clinicians choose to assess patientsrsquo nonprescriptioncannabinoid use there is a validated SISQ for drugs in-cluding cannabis (ie ldquoHow many times in the past yearhave you used an illegal drug or used a prescriptionmedication for nonmedical reasonsrdquo) [93] with a sensi-tivity of 97 and a specificity of 79 for substance usedisorders in primary care settings [130] Although somemetabolites of synthetic cannabinoids (eg spice) canbe analyzed with specialized immunoassayschromatographyspectrometry-based assays are betterfor assessing the many emerging synthetic cannabi-noids and their metabolites [138]
A subject of ongoing debate is whether co-administration of opioids and cannabis (used
recreationally or medically) is safe or reasonable for clini-cians to allow Cannabis is increasingly accepted formedical purposes especially for cancer pain syn-dromes However allowing patients with chronic pain touse cannabis is a potential liability for clinicians (includ-ing pharmacists) regardless of the drugrsquos legal status intheir state [139] The safety of cannabis for patients withchronic pain is not clearly established [140] and little isknown regarding the safety of concurrent use withopioids apart from the potential opioid-sparing effects ofcannabis [141] The composition and dose of the manyactive components in cannabis vary widely [133142]which leads to variable toxicity [143] and complicatessafety studies Cannabinoids may inhibit cytochromeP450 2D6 [144] (involved in opioid metabolism [145])and therefore affect both the efficacy of opioids and theability to detect metabolites in UDM The panelists pro-posed that a single clinician be responsible for manag-ing both opioid and cannabis use in states where thedrug has been decriminalized and the benefits of con-current use outweigh the risks
Interpreting UDM Results and Implications forChanging Clinical Practice
The panelists believe that clinicians should follow manu-facturer instructions for specific POC UDM tests and di-rect any questions about interpreting results to anexpert in toxicology or clinical pathology Laboratoriesperforming UDM have a responsibility to provide cleartest results answer questions and offer support on clin-ical decisions When clinicians are confronted with un-expected results potential causes for false-positive andfalse-negative results (eg quinolone antibiotics tolme-tin Figure 1) are important to investigate A summary ofcommunications and discussions about results with thelaboratory and other experts can be included in themedical record to document the medical necessity oftesting and related clinical decision-making
Communications with patients about the purpose andresults of UDM should be nonjudgmental and nonpuni-tive and should focus on safety and risks associatedwith misuse and opioid use disorder To avoid unex-pected results open discussion with patients is recom-mended and may include asking questions such as ldquoIfwe test you today what will we find in your urine Willthere be any surprisesrdquo Development of a plan to ad-dress UDM results that are inconsistent with therapy issuggested to mitigate safety risks for patients and po-tential regulatory board sanctions for clinicians Of noteUDM results that are consistent with prescribed opioidscannot differentiate among appropriate use occasionaluse or misuse and opioid use disorder negative UDMresults for prescribed opioids cannot distinguishbetween infrequent need for medicine overuse and run-ning out falsification of the urine sample and diversionResults of UDM are only part of the clinical information

(eg including patient history) that must be consideredbefore a treatment plan is changed
Detailed recommendations on proper opioid prescribingand appropriate changes to patient care after unex-pected UDM results are outside the scope of this con-sensus report but are discussed in other guidelines[18202240] In brief options to address unexpectedUDM results include open and nonjudgmental discus-sions with patients additional confirmation testing in-creased monitoring a switch to a nonopioid painmedication or referral for treatment of an opioid usedisorder [18202240]
Three studies from the Philadelphia VA Medical Center in-vestigated how UDM results affected provider behavior[119146147] additional research to determine how UDMresults should influence patientsrsquo therapy is warranted Inthe absence of this information a follow-up consensusmeeting to evaluate expert opinion was suggested
Conclusions
In summary the expert panel made the following rec-ommendations regarding UDM (Figure 2)
1 Use definitive UDM testing (eg with GC-MS LC-MS or LC-MSMS) as the most clinically appropriatemethod for assessing baseline opioid use and opioidmisuse in most patients with chronic pain being con-sidered for opioids as well as for ongoing monitoringof patients receiving opioids for chronic pain unlesspresumptive testing is required by institutional orpayer policies A rational approach to choosing themost relevant analytes for UDM testing is proposedand should be documented by the clinician
2 To guide UDM frequency assess and stratify patientsprescribed opioid therapy for chronic pain with thefollowing strategies
bull perform a physical examination and obtain relevantpatient history for eventsdiagnoses and behaviorsthat have been shown to predict opioid misuseand opioid use disorder (eg history of substanceuse disorders psychiatric conditions sexual abuse)including information from previous providers forpatients transferring care
bull use validated tools to assess risk for aberrantmedication-taking behavior opioid misuse opioiduse disorder and the potential for respiratory de-pressionoverdose
bull check PDMPs and previous UDM results whenavailable
3 Perform UDM at baseline in patients receiving opioidsfor chronic pain During ongoing monitoring performUDM at least annually for low-risk patients two ormore times per year for moderate-risk patients andthree or more times per year for high-risk patientsAdditional monitoring can be performed as frequently
as necessary according to clinical judgment (egworrisome patient behavior related to the prescribedmedication)
The recommendations in this consensus report are meantto provide practical advice on implementing rational UDMacross a broad range of clinical practices in a patient-centric manner Some clinicians may not have access toappropriate resources to perform routine definitive UDMor to refer patients to pain specialists alternatives are pro-vided in the expert panel discussion sections Higher-quality studies on patient outcomes with UDM areneeded As a next step a consensus recommendationinitiative similar to this one that discusses appropriate clini-cian actions in response to test results that are inconsis-tent with prescribed therapy is warranted

(eg including patient history) that must be consideredbefore a treatment plan is changed
Detailed recommendations on proper opioid prescribingand appropriate changes to patient care after unex-pected UDM results are outside the scope of this con-sensus report but are discussed in other guidelines[18202240] In brief options to address unexpectedUDM results include open and nonjudgmental discus-sions with patients additional confirmation testing in-creased monitoring a switch to a nonopioid painmedication or referral for treatment of an opioid usedisorder [18202240]
Three studies from the Philadelphia VA Medical Center in-vestigated how UDM results affected provider behavior[119146147] additional research to determine how UDMresults should influence patientsrsquo therapy is warranted Inthe absence of this information a follow-up consensusmeeting to evaluate expert opinion was suggested
Conclusions
In summary the expert panel made the following rec-ommendations regarding UDM (Figure 2)
1 Use definitive UDM testing (eg with GC-MS LC-MS or LC-MSMS) as the most clinically appropriatemethod for assessing baseline opioid use and opioidmisuse in most patients with chronic pain being con-sidered for opioids as well as for ongoing monitoringof patients receiving opioids for chronic pain unlesspresumptive testing is required by institutional orpayer policies A rational approach to choosing themost relevant analytes for UDM testing is proposedand should be documented by the clinician
2 To guide UDM frequency assess and stratify patientsprescribed opioid therapy for chronic pain with thefollowing strategies
bull perform a physical examination and obtain relevantpatient history for eventsdiagnoses and behaviorsthat have been shown to predict opioid misuseand opioid use disorder (eg history of substanceuse disorders psychiatric conditions sexual abuse)including information from previous providers forpatients transferring care
bull use validated tools to assess risk for aberrantmedication-taking behavior opioid misuse opioiduse disorder and the potential for respiratory de-pressionoverdose
bull check PDMPs and previous UDM results whenavailable
3 Perform UDM at baseline in patients receiving opioidsfor chronic pain During ongoing monitoring performUDM at least annually for low-risk patients two ormore times per year for moderate-risk patients andthree or more times per year for high-risk patientsAdditional monitoring can be performed as frequently
as necessary according to clinical judgment (egworrisome patient behavior related to the prescribedmedication)
The recommendations in this consensus report are meantto provide practical advice on implementing rational UDMacross a broad range of clinical practices in a patient-centric manner Some clinicians may not have access toappropriate resources to perform routine definitive UDMor to refer patients to pain specialists alternatives are pro-vided in the expert panel discussion sections Higher-quality studies on patient outcomes with UDM areneeded As a next step a consensus recommendationinitiative similar to this one that discusses appropriate clini-cian actions in response to test results that are inconsis-tent with prescribed therapy is warranted
