Multidrug-Resistant Organisms (MDROs): Background
• Infectious agents that are resistant to key antimicrobials. May include resistance to: – One or more antimicrobials – All but one antimicrobial or class – All antimicrobials and classes – Three or more antimicrobial classes*
• Limited treatment options • Associated morbidity/mortality

Reducing Transmission of MDROs in Healthcare Settings
• Administrative measures and adherence monitoring • Education and training of healthcare personnel • Surveillance (know the scope of the problem) • Infection control precautions
– Basic strategies – hand hygiene, isolation precautions – Enhanced strategies – active surveillance testing
• Environmental measures • Judicious use of antimicrobial agents

General Recommendations: Environmental Measures
• Clean and disinfect surfaces in close proximity to patient and high-touch surfaces more frequently than minimal-touch surfaces
• Dedicate non-critical equipment to use on individual patients colonized or infected with MDROs
• Prioritize room cleaning of patients on contact precautions
• ? Audit cleaning practices • Use advanced room cleaning techniques?

Judicious Use of Antimicrobial Agents/ Antimicrobial Stewardship
• Processes designed to measure and optimize the appropriate use of antimicrobials
• Achieved by selecting the appropriate agent, dose, duration of therapy and route of administration
• Implement systems to prompt clinicians to use appropriate agents – Provide antibiograms at least annually
• Implement process for review and feedback of prescribed antimicrobials

Active Surveillance Testing • Practice of culturing asymptomatic patients
for the presence of MDRO (colonized) • Prevalence of MDRO may be greater than
anticipated, even if there have only been a few clinical cases

Making the Business Case for MDRO Prevention
• Should address the following: – What is the extent of the problem? – Will the proposed program effectively address the
problem? – Is the program aligned with institutional
goals/values?? – What is the cost of the program? – What are the potential unintended consequences of
the program?
![Page 14: Building a Business Case for Control of Multidrug ...€¦ · – Basic strategies – hand hygiene, isolation precautions – Enhanced strategies – active surveillance testing](https://reader033.vdocument.in/reader033/viewer/2022060604/6059aa70e4b0d06f8638eb30/html5/thumbnails/14.jpg)
Making the Business Case for MDRO Prevention
• Should address the following: – What is the extent of the problem? – Why is it a problem worth addressing?
• Disease burden • Clinical consequences • Financial consequences
![Page 15: Building a Business Case for Control of Multidrug ...€¦ · – Basic strategies – hand hygiene, isolation precautions – Enhanced strategies – active surveillance testing](https://reader033.vdocument.in/reader033/viewer/2022060604/6059aa70e4b0d06f8638eb30/html5/thumbnails/15.jpg)
Clinical Consequences of MDROs
• How much of a clinical impact does acquiring an MDRO infection have on your patients?
• Depends upon several factors -- – How much disease is present? – How severe of an outcome will a
patient will have if he/she becomes infected?
![Page 16: Building a Business Case for Control of Multidrug ...€¦ · – Basic strategies – hand hygiene, isolation precautions – Enhanced strategies – active surveillance testing](https://reader033.vdocument.in/reader033/viewer/2022060604/6059aa70e4b0d06f8638eb30/html5/thumbnails/16.jpg)
Assessing the Burden of an MDRO
Proportion # of isolates of MDRO x
100 Total # of isolates
Ex: 62% of Staphylococcus aureus isolates in Q2 were
MRSA
Rate # of isolates of MDRO
Unit of time
Ex: 3.7 MRSA isolates per 100 hospital admissions in Q2

Rate •Independent of changes in non-MDRO isolates •Can accurately evaluate impact of new procedures or policies

Clinical Consequences of MDROs
• How much of a clinical impact does acquiring an MDRO infection have on your patients?
• Depends upon several factors -- – How much disease is present? – How severe of an outcome will a
patient will have if he/she becomes infected?
![Page 20: Building a Business Case for Control of Multidrug ...€¦ · – Basic strategies – hand hygiene, isolation precautions – Enhanced strategies – active surveillance testing](https://reader033.vdocument.in/reader033/viewer/2022060604/6059aa70e4b0d06f8638eb30/html5/thumbnails/20.jpg)
• Patients with an MDRO infection will have limited treatment options compared to those with a more antibiotic-susceptible infection.
• For some MDROs, only 1 or 2 antibiotics are left for treatment, and these often have toxic side effects.
Clinical Consequences of MDROs
![Page 21: Building a Business Case for Control of Multidrug ...€¦ · – Basic strategies – hand hygiene, isolation precautions – Enhanced strategies – active surveillance testing](https://reader033.vdocument.in/reader033/viewer/2022060604/6059aa70e4b0d06f8638eb30/html5/thumbnails/21.jpg)
• Studies examining several different types of MDROs have noted an increased risk of death in patients with an MDRO infection.
• This risk is still present when comparing patients with MDRO infection to those with infection due to a more susceptible strain of the same bacteria.
• This may be due to increased virulence of the MDRO, delays in antibiotic therapy that will treat the organism, underlying patient illnesses, or all of the above.
Clinical Consequences of MDROs: Mortality
![Page 22: Building a Business Case for Control of Multidrug ...€¦ · – Basic strategies – hand hygiene, isolation precautions – Enhanced strategies – active surveillance testing](https://reader033.vdocument.in/reader033/viewer/2022060604/6059aa70e4b0d06f8638eb30/html5/thumbnails/22.jpg)
• Patients with and MDRO infection have an increased risk of death compared to patients with infection due to a susceptible strain: – MRSA Bloodstream Infection 2X Risk – MRSA Ventilator-Associated Pneumonia 2X Risk – Any MRSA Infection 2X Risk
– VRE Bloodstream Infection 2-2.5X Risk – ESBL Producer Bloodstream Infection 2X Risk – MDR Acinetobacter Bloodstream Infection 4X Risk

• Multiple studies with several different types of MDROs have shown that MDRO-infected patients also have – d length of hospitalization – d risk of ICU admission – d ICU length of stay
Clinical Consequences of MDROs: Morbidity
![Page 27: Building a Business Case for Control of Multidrug ...€¦ · – Basic strategies – hand hygiene, isolation precautions – Enhanced strategies – active surveillance testing](https://reader033.vdocument.in/reader033/viewer/2022060604/6059aa70e4b0d06f8638eb30/html5/thumbnails/27.jpg)
The Costs of MDROs: Economic Impact
• Increasing number of studies on costs of MDROs • Methodology varies widely • Examine “cost” definitions closely
– “Cost” vs. “Charge” – Include fixed costs (e.g. nursing)?
• Ask for help from finance colleagues – The “Our Own Data” syndrome
![Page 28: Building a Business Case for Control of Multidrug ...€¦ · – Basic strategies – hand hygiene, isolation precautions – Enhanced strategies – active surveillance testing](https://reader033.vdocument.in/reader033/viewer/2022060604/6059aa70e4b0d06f8638eb30/html5/thumbnails/28.jpg)
Assessing the Costs of MDRO Infections
• Fixed costs – Accrue regardless of case volume
• Physical plant costs • Equipment • Base-level staffing
– Prevention of outcome may not prevent these costs • e.g. Still need to support nurse staffing even if
MDROs reduced
![Page 29: Building a Business Case for Control of Multidrug ...€¦ · – Basic strategies – hand hygiene, isolation precautions – Enhanced strategies – active surveillance testing](https://reader033.vdocument.in/reader033/viewer/2022060604/6059aa70e4b0d06f8638eb30/html5/thumbnails/29.jpg)
• Variable costs – Per case expenses
• Supplies • Medications • Variable staffing
– If decreased nurse-to-patient staffing with MDRO + patients, may be impacted by prevention programs

Making the Business Case for MDRO Prevention
• Should address the following: – What is the extent of the problem? – Will the proposed program effectively address the
problem? • Include studies that show impact of prevention
efforts on outcome • Important to identify facilities of similar
composition to your own
