- W2019969664 abstract "Methicillin-resistant Staphylococcus aureus (MRSA) is a nosocomial pathogen that has become increasingly prominent in hospitals and the community. HIV-positive patients may be one of the most MRSA-susceptible populations because of their immunocompromised status. At the Communicable Disease Centre, Tan Tock Seng Hospital, Singapore, we implemented a universal MRSA screening program and performed a case-control study to identify risk factors for MRSA colonization among 294 HIV patients at admission from January 2009 to January 2010. Among 54 HIV-positive patients who were MRSA positive at hospital admission, 16 (29.6%) were positive at the nares/axilla/groin (NAG; one combined swab), 14 (25.9%) were NAG and perianal positive, 3 (5.6%) were NAG and throat positive, 10 (18.5%) were NAG, perianal, and throat positive, 6 (11.1%) were throat positive, and 5 (9.3%) were perianal positive. Upon multivariate analysis, we found that age [odds ratio (OR)=1.04, 95% confidence interval (CI): 1.01-1.07, p=0.006] and CD4 count <200/μl within the past 6 months (OR=4.29, 95% CI: 1.83-10.06, p=0.001) were significant risk factors for MRSA colonization. We generated a receiver operating characteristic curve using these two variables and found that the area under the curve was 0.69, indicating that age and CD4 count <200/μl performed moderately well in discriminating between those with MRSA colonization and those without. The results of our study indicate that HIV patients of older age and reduced CD4 count may have increased risk of MRSA colonization. These risk factors may serve as indicators for cohorting or isolating HIV patients at hospital admission." @default.
