Methicillin-resistant Staphylococcus aureus in a nursing home.
Infection Control : IC
|January 1, 1987
Summary
Methicillin-resistant Staphylococcus aureus (MRSA) infections were identified in a nursing home, with evidence suggesting acquisition within the facility. Control measures reduced but did not eliminate new cases of this concerning bacterial pathogen.
Area of Science:
- Infectious Diseases
- Epidemiology
- Geriatric Medicine
Background:
- Methicillin-resistant Staphylococcus aureus (MRSA) poses a significant threat in healthcare settings.
- Nursing homes may act as reservoirs for MRSA transmission within communities.
Purpose of the Study:
- To investigate an outbreak of MRSA in a nursing home.
- To identify the source and extent of MRSA colonization and infection.
- To evaluate the effectiveness of control measures.
Main Methods:
- Retrospective review of cases over 13 months.
- Culture surveys of residents and personnel.
- Implementation and assessment of infection control protocols.
Main Results:
- 25 residents had positive MRSA cultures, with 17 experiencing infections.
- MRSA was detected in 12% of surveyed residents and 7% of personnel.
- Evidence suggested MRSA acquisition within the nursing home environment.
- Control measures decreased but did not eradicate new MRSA cases.
Conclusions:
- Nursing homes can be sites for MRSA acquisition and transmission.
- Ongoing surveillance and robust control measures are crucial.
- Further research is needed to optimize MRSA management in long-term care facilities.
