EHRs)• Health IT “adoption”• Health informatics education

EHRs: Fundamentals

What Is A Medical Record?

What Is A Medical Record?

• A record or documentation of a patient’s medical history, examination, and treatments.

• Medical Record vs. Health Record– Essentially the same

Class Exercise 1

• Why do we need a health record?

Class Exercise 1

• Why do we need a health record?

• In other words, why do we need a documentation of a patient’s medical care?

Potential Uses of Medical Records

• Continuity of providing care– Note important information for later use– Especially important in chronic diseases

(e.g. hypertension, diabetes) or in follow-up (e.g. after surgery)

• Patient safety– Preventing something bad because of lack of information– Such as drug allergies, list of current medications,

“problem list”


• Communications between providers– Referral to specialists or other physicians– Consulting among physicians– Communications between physicians and nurses,

pharmacists, physical therapists, etc.– Transfer from a hospital to another

• Medico-legal purposes– e.g. Court evidence against malpractice– What was done or provided to the patient? Why? By

whom? When?– Was the care provided up to the professional standard?


• Claims and reimbursements– What services were provided to the patient– How (and how much) will the hospitals/doctors be paid?– Audit of medical records by “payers”

• Patient’s uses– Health insurance claims– Self-education & self-care

• Clinical research– Find ways to improve health care through new knowledge

Class Exercise 2

• What do you think should be in the medical records?

Data Elements in Medical Records

• Patient demographics• General information about each visit (visit = encounter)

– Type (outpatient, inpatient, emergency)– Date/Time– Location (clinic or ward)

“Clinical Notes”• Patient’s problems (“Patient history”)

– Chief complaint– Present illness– Past history– Family and social history


• Clinical findings by physicians (“Physical examination”)– Any important positive (usually abnormal) findings– Also important negative (usually normal) findings

• “Investigations”– Laboratory tests (blood tests, urine, etc.)– Radiological examinations (X-rays, CT, MRI, ultrasound)– Other diagnostic procedures

• Electrocardiography (EKG/ECG) -- heart’s function• Electroencephalography (EEG) -- brain wave scans• Etc.


• “Problems” or “Diagnoses”– Summary of problems relevant to this visit

• Treatments– Medications– Surgical procedures– Advice to patients– Admission (hospitalization)

• Plans– Surgeries– More investigations to be done later– Follow-up appointments


• Inpatient clinical notes– Admission notes– Orders (medications, procedures, investigations, nursing

care, etc.)– Medication administration records– Vital signs and other measurements– Results of lab tests and radiological examinations– Progress notes– Discharge summary

“Electronic” Medical Records

• Electronic Medical Records (EMRs) vs. Electronic Health Records (EHRs)

• Debate about similarities & differences• Summary

– Definitions subjective, depending on how people think– EMRs mostly refer to electronic documentation of

medical care at one visit– EHRs mostly refer to electronic documentation that is

longitudinal in nature (may be several visits)– EMRs commonly used in Thailand (but means the same

as EHRs)

Benefits of EHRs and EHR Adoption

Innovation Adoption

• Innovation: “an idea, practice, or object that is perceived as new by an individual or other unit of adoption”– EHRs and health IT are innovation

• Adoption: “a decision to make full use of an innovation as the best course of action available”

• Diffusion of innovations theory (Rogers, 2003)

Class Exercise 3

• Why do we need to “adopt” an electronic version of medical records?

“Computerize”“Go paperless”

“Digital Hospital”

“Modernize”

“Get an electronic copy

“Have EMRs”

“Share data”

Common “Goals” for EHRs/Health IT Adoption

Is There A Role for Health IT?

(IOM, 2000)

Landmark IOM Reports

(IOM, 2001)(IOM, 2000)

Landmark IOM Reports: Summary

• Humans are not perfect and are bound to make errors

• Highlight problems in the U.S. health care system that systematically contributes to medical errors and poor quality

• Recommends reform that would change how health care works and how technology innovations can help improve quality/safety

Why We Need Health IT

• Health care is very complex (and inefficient)• Health care is information-rich• Quality of care depends on timely availability &

quality of information• Clinical knowledge body is too large• Short time during a visit• Practice guidelines are put “on-the-shelf”• “To err is human”

To Err Is Human

• Perception errors

To Err Is Human

What If This Happens in Healthcare?

• It already happens....(Mamede et al., 2010; Croskerry, 2003; Klein, 2005)

• What if health IT can help?

Fundamental Theorem of Informatics

(Friedman, 2009)(Friedman, 2009)

Underlying Assumption

Adoption of EHRs

Use of EHRs

Better Outcomes

Underlying Assumption

Individual Adoption & use

• Better clinical outcomes• Improved patient satisfaction• More provider productivity/satisfaction

Organizational Adoption & Use

• Improved operational efficiency• Better data for research, quality improvements• Reduced costs/increased revenues (e.g. better

claims & reimbursements)

Societal Adoption & Use

• Better individual health/quality of life• Better population health• Long-term cost savings

Benefits of Going Electronic (EHRs)

• Ubiquitous availability (anytime, anywhere, everyone who is authorized)

• Multiple concurrent uses• The end of “Where the heck is the patient’s record?!?”• Ability to control & enforce access security• Structured data entry possible• Data presentation that is easier to understand (e.g. graphs)• Efficiency in data entry? (but sometimes it slows users

down!)• Process improvement (business process

reengineering/redesign, quality improvement)

• No doctor’s handwriting!!!!!

• Are they just electronic documentation?

• Or do they have some other values?

Treat-ments ...

Electronic Health Record (EHR) Systems

• Literature suggests improvement in health care through

– Guideline adherence– Better documentation– Practitioner decision making or process of care – Medication safety– Patient surveillance & monitoring– Patient education/reminder– Cost savings and better financial performance

Literature Shows Benefits of Health IT

• Patient Demographics• Physician Notes• Computerized Medication Order Entry• Computerized Laboratory Order Entry• Computerized Laboratory Results• Problem Lists• Medication Lists• Discharge Summaries• Diagnostic Test Results• Radiologic Reports

EHRs: Implementation Issues

EHR Systems/HIS: Issues

• Functionality & workflow considerations• Structure & format of data entry

– Free text vs structured data forms– Usability– Use of standards & vocabularies (e.g. ICD-10, SNOMED CT)– Templates (e.g. standard narratives, order sets)– Level of customization per hospital, specialty, location, group, clinician– Reduced clinical value due to over-documentation (e.g. medico-legal, quality

accreditation)– “Copy & Paste” garbage– Special documents (e.g. operative notes, anesthetic notes)– Integration with paper systems (e.g. scanned records, legal documents)

• Reliability & contingency/business continuity planning

• Roll-out strategies & change management• Are they going to slow down patient care

process?• System Interfaces

Increasing EHR Adoption

Facilitators of EHR Adoption

Jha et al. (2009)

Barriers to EHR Adoption

Jha et al. (2009)

• “Workarounds”

EHR Adoption Barriers(Why People Don’t Use EHRs?)

• Technical & design issues– Poor software implementation

• Does not meet requirements• Buggy

– Poor usability and user experience• Complex/clunky UI• Easy to make error or miss something

– Poor system performance• Slow• Unreliable


• Management issues– Does not seem to improve their work process– Too much work entering data– Unclear values to users (or even negative outcomes!)

• “Unintended consequences” of using health IT– Executives not fully supporting the project– “Power shift” among users– Communications and engagement (involvement) of users

early and repeatedly during various phases of the project– Poor training and technical support– Users perceived they are treated poorly or their voices are

not heard


The Importance of “Change Management”

“One of the most important lessons learned to date is that the complexity of human change management may be easily underestimated”

Langberg ML (2003) in “Challenges to implementing CPOE: a case study of a work in progress at Cedars-Sinai”

Public Policy on EHR Adoption

Political Support Behind Health IT

“...We will make wider use of electronic records and other health information technology, to help control costs and

reduce dangerous medical errors.”

“Meaningful Use” of Health IT

Stage 1- Electronic capture of health information- Information sharing- Data reporting

Stage 2

Use of EHRs to improve processes of care

Stage 3

Use of EHRs to improve outcomes

Better Health

(Blumenthal D, 2010)

• Electronic capture of information– Demographics– Vital signs– Medication list– Allergies– Problem list– Smoking

• Medication order entry• Drug-allergy & drug-drug interaction checks• Patient access to/copy of health information

Meaningful Use Final Rule: Core Objectives (Selected)

• Drug formulary checks• Lab results incorporation into EHRs• Generate lists of patients by specific conditions• Medication reconciliation• Electronic reporting to governmental agencies• Advanced directives for elderly patients• Patient reminders for certain services (for clinics)• Patient access to health information (for clinics)

Meaningful Use Final Rule: Menu Set (Selected)

• Content Exchange Standards– HL7 CDA Release 2 & CCD– NCPDP SCRIPT

• Vocabularies– SNOMED CT– LOINC®

– RxNorm ®

• Security– NIST-certified encryption algorithms

• Etc.

Final Rule on Standards & Certification Criteria (Selected)


• “An electronic application through which individuals can access, manage and share their health information, and that of others for whom they are authorized, in a private, secure, and confidential environment.” (MarkleFoundation, 2003)

• “A PHR includes health information managed by the individual... This can be contrasted with the clinician’s record of patient encounter–related information [a paperchart or EHR], which is managed by the clinician and/or health care institution.” (Tang et al., 2006)

Types of PHRs

• Patient portal from a provider’s EHRs (“tethered” PHRs)

• Online PHRs– Stand-alone– Can be integrated with EHRs from multiple providers

(unidirectional/bidirectional data sharing)

• Stand-alone PHRs– PC-based applications– USB Drive– CD-ROM or other data storage devices– Paper

Ideal PHRs

• Integrated• Accessible• Secure• Comprehensive• Accurate & current• Patient able to

manage sharing & update information

• Engaging & educational

• User-friendly, culturally & literacy appropriate

The “Hub and Spoke” Model(Kaelber et al., 2008)

Use Cases of PHRs

• Data entry/update by patients• Data retrieval by providers

– With patient’s consent

– “Break-the-glass” emergency access

• Data update from EHRs• Privacy settings• Personalized patient education• Communications with providers

• This is why we need standards!!!– Information exchange from one EHR system to

another needs standards– Seamless exchange of information would

improve quality, continuity, and efficiency of care

Implications

• EHRs (or EMRs) are both– Electronic documentation of patient care and– a broad term for an information system used to

improve the process of patient care through better documentation and other care processes such as ordering medications, lab tests, or x-rays and viewing lab results and x-ray reports (among others)

Summary

• It is important to focus both on the technical aspect of EHR implementation as well as the management aspect (such as change management)

• Otherwise, a well-designed system may not be used, and patient care is not improved

• Many countries are trying to improve the EHR“adoption rate”

• EHRs are just one piece of the big puzzle for the whole healthcare system

• PHRs are a separate, but related concept of EHRs
