BEST PRACTICES: MRSA PRECAUTIONS Dr. Elizabeth Bryce
Topics to Be Covered • Devising Risk Strategies • Risk Assessment for Level of Precautions • Determining the Need for Additional Precautions
Devising Risk Strategies: Waxing Philosophical To develop effective prevention strategies must understand the components responsible for the current state in your facility: • Rates of Community acquired MRSA • Rates of Healthcare Acquired MRSA • Rates in your Facility The same situation? Very high rates of CMRSA+ high incidence of HCMRSA + endemic in facility VS Little CMRSA + little HCMRSA + low facility rates
Risk management strategies… BUT also consider: • Your Patient Population • Your Environment • Impact of implementation plan/procedures • Feasibility • Probability of Effectiveness of measures MRSA Eradication What is the goal of your strategy? MRSA Control?
But Wait …..There’s More! Who will you target? • The Facility Population? • Just Inpatients? Or Residents? • Pre-Admit Population (prior to admission) • The Community?
Risk Assessment Transmission and persistence determined by: • Vulnerable patients • Selective antimicrobial pressure • Colonization pressure • Impact of implementation strategies • Continued adherence to prevention (long-term investment)
Risk Assessment Two components to remember • Organizational risk assessment which sets policy and procedure • Individual risk assessment with each patient interaction
General Control Interventions • Administrative Support • Antimicrobial Stewardship • Surveillance • Environmental Cleanliness • Routine/Contact Precautions • Education • Additional Precautions • Critical Review of implementation strategies
Administrative Support • Fiscal Resources • Human Resources • Implementing System Changes • Physical Plant Changes • Promoting Adherence/Role Modeling • Fostering a Safety Climate
Antimicrobial Stewardship • Shortest duration possible • Narrowest spectrum possible • Treat the patient, not the report! • Formulary Reviews • Built-in Compliance features in Pharmacy • Practice Guidelines
Environmental Cleanliness • Correct Agent/Dilution • Correct method • Avoid Clutter • Focus on frequently touched surfaces • Isolation Cleaning Protocols • Don’t forget shared equipment
Education Many different strategies • Facility-wide versus focused • Informational, interactive, training, campaigns • Ideally behaviour change oriented And trying to effect a culture change
Routine Precautions • Have an essential role in preventing transmission – always • Particularly important vis a vis undetected cases • Hand Hygiene particularly important here as is Risk Assessment
Additional Precautions Very important to consider the context and the situation Contact Precautions: Evidence: Consensus versus evidence based recommendation. Elements: single/isolation rooms or cohorting, use of gown and gloves for potential patient contact or contact with contaminated areas Unresolved: Duration of CP Impact of CP on patient well-being and care Use of CP preemptively
Other Barriers • For the most part; as per Routine Precautions • Mask – anticipated exposure to droplets/secretions • Respirator – generally not specifically for MRSA • Facial Protection – anticipated exposure to droplets/secretions
Other Measures • Notifying others of patient transfers or diagnostic procedures • Ensuring patients clean hands and cover open wounds when outside room • Visitors informed of appropriate precautions • Education of patient
Finally…… Control of MRSA should be • Dynamic • Systematic • Tailored to reflect the epidemiology/environment • Flexible – can be scaled up or down • Measured Strive to: Assess the problem, evaluate the effectiveness of the measures implemented.
