Summary
Methicillin-resistant Staphylococcus aureus (MRSA) colonization is high in intermediate care facilities. Screening patients with wounds can help target MRSA decolonization efforts effectively.
Area of Science:
- Infectious Diseases
- Hospital Epidemiology
- Antimicrobial Resistance
Context:
- High prevalence of methicillin-resistant Staphylococcus aureus (MRSA) observed in Poitiers teaching hospital.
- Intermediate care facilities identified as a particular hotspot for MRSA colonization.
Purpose:
- To survey MRSA colonization in intermediate care facilities.
- To identify risk factors for MRSA carriage and infection.
- To evaluate the effectiveness of a decolonization procedure.
Summary:
- A survey of 265 patients in intermediate care facilities revealed MRSA colonization rates of 17.7% on admission and 30.4% on departure.
- A significant increase in MRSA carriage was observed among patients admitted as non-carriers (24.3%).
- The presence of a wound was the primary risk factor for MRSA carriage (RR = 3.6), with an overall MRSA infection incidence of 3%.
Impact:
- Findings suggest that systematic MRSA screening is costly and difficult to implement in intermediate care.
- A targeted screening approach focusing on patients with wounds is proposed to optimize resource allocation.
- This study informs infection control strategies for MRSA in hospital settings.
