Hypothesis
What are the risk factors for clinically-significant MRSA infections in HIV-infected patients admitted to Infectious Diseases Units?
Conclusion
Clinicians should be aware of the risk for CS-MRSA infection in HIV-infected patients with low CD4 cell counts, longer previous hospital stays, and previous invasive procedures.
Supporting Evidence
- 27 cases of CS-MRSA infections were identified among HIV-infected patients.
- The risk for CS-MRSA increased by 14% for every 5 days of hospitalization in the previous year.
- Only 1 out of 27 patients had community-acquired MRSA infection.
Takeaway
HIV patients who have been in the hospital a lot or have low immune system counts are more likely to get a serious infection from a germ called MRSA.
Methodology
A retrospective case-control study was conducted to identify risk factors for CS-MRSA infection among HIV-infected patients.
Potential Biases
Potential bias due to the retrospective design and reliance on medical records.
Limitations
The study had a limited number of cases and relied on retrospective data collection, which may have led to underreporting of hospital days.
Participant Demographics
27 HIV-infected patients with a median age of 43 years, predominantly male (74%), and a significant proportion with low CD4 counts.
