What precautions should caregivers take to prevent the spread of Methicillin-resistant Staphylococcus aureus (MRSA)?

Caregiver Precautions for MRSA

Healthcare workers and caregivers must implement strict hand hygiene, wear gloves and gowns when caring for MRSA-infected or colonized patients, and ensure proper environmental cleaning with appropriate disinfectants to prevent MRSA transmission.

Hand Hygiene - The Foundation of MRSA Prevention

Hand hygiene is the single most important method for preventing MRSA transmission:

• Preferred method: Use alcohol-based hand rubs when hands are not visibly soiled 1

  • More effective at removing organisms
  • Requires less time
  • Causes less skin irritation than soap and water
  • Increases compliance with hand hygiene protocols

• When to perform hand hygiene:

  • Before and after each patient contact
  • After removing gloves
  • Between dirty and clean procedures on the same patient
  • After contact with potentially contaminated surfaces or equipment 2, 1

• Technique:

  • Apply enough product to cover all hand surfaces
  • Rub hands together until dry
  • For visibly soiled hands, wash with soap and water 1

Personal Protective Equipment (PPE)

1. Gloves:

   • Wear clean, non-sterile gloves when entering the room of a MRSA-infected or colonized patient 3
   • Change gloves after contact with material containing high concentrations of MRSA (e.g., wound drainage, stool) 3
   • Remove gloves before leaving the patient's room 3
   • Never wash or reuse gloves 4

2. Gowns:

   • Wear a clean, non-sterile gown when entering the room if:
     • Substantial contact with the patient is anticipated
     • Contact with environmental surfaces in the patient's room is likely
     • The patient is incontinent or has uncontained drainage 3
   • Remove gown before leaving the patient's room 3
   • Change immediately if visibly soiled or penetrated by blood/body fluids 4

3. Proper Sequence for Removing PPE:

   • Remove gloves first
   • Perform hand hygiene immediately after glove removal
   • Remove gown
   • Perform hand hygiene again 3, 1

Patient Placement and Isolation

• Place MRSA-infected or colonized patients in private rooms when possible 3, 5
• If private rooms are unavailable, cohort MRSA patients together 3, 5
• Implement contact precautions for all encounters with MRSA-colonized patients 5
• Ensure proper communication about MRSA status when transferring patients to other facilities 5

Environmental Cleaning and Disinfection

• Pay close attention to high-touch surfaces in patient care areas:

  • Bed rails
  • Bedside commodes
  • Doorknobs
  • Faucet handles
  • Medical equipment 6

• Use EPA-registered disinfectants appropriate for the surface 6

• Ensure compliance with cleaning and disinfection procedures by housekeeping staff 6

• Consider using dedicated equipment for MRSA patients:

  • Stethoscopes
  • Blood pressure cuffs
  • Thermometers 3, 6

• If equipment must be shared, thoroughly clean and disinfect between patients 3

Special Considerations

• Artificial nails: Do not wear artificial fingernails when caring for high-risk patients 4
• Jewelry: Avoid hand or nail jewelry that makes glove use difficult or compromises glove integrity 4
• Duration of precautions: MRSA colonization can persist indefinitely; consider multiple negative cultures (at least three consecutive negative results from multiple body sites) before discontinuing precautions 3

Common Pitfalls to Avoid

1. Inadequate hand hygiene: The most common cause of healthcare-associated infections 1
2. Improper glove removal: Can lead to hand contamination even with glove use 7
3. Premature discontinuation of contact precautions: MRSA colonization can persist for extended periods 3
4. Neglecting environmental cleaning: MRSA can survive on environmental surfaces 6
5. Inconsistent adherence to protocols: Regular education and monitoring of compliance is essential 5

By consistently implementing these precautions, caregivers can significantly reduce the risk of MRSA transmission in healthcare settings and protect both patients and themselves from infection.
