Risk factors for nasal carriage of methicillin- resistant Staphylococcus aureus among patients with end-stage renal disease in Taiwan

BACKGROUND/PURPOSE Patients with end-stage renal disease (ESRD) are at particular risk for methicillin-resistant Staphylococcus aureus (MRSA) infections, especially via nasal colonization of MRSA. Surveillance cultures are recommended to identify patients colonized by MRSA. METHODS Clinical data and screening cultures of S. aureus from the anterior nares of 541 patients on long-term dialysis in the hospitals were performed in March 2007. The follow-up survey was conducted 1 year later. RESULTS A total of 32 (5.9%) of the 541 patients were positive nasal cultures for MRSA, while 89 (16.5%) were positive for methicillin-susceptible S. aureus (MSSA). In a multivariate analysis, risk factors for ESRD patients with MRSA colonization included congestive heart failure, nursing home admission, and nasogastric tube feeding in the last 3 months. Follow-up of the 32 MRSA colonized patients showed that one (3.1%) died due to MSSA and three (9.3%) died due from MRSA infection. CONCLUSIONS We found that patients with ESRD and MRSA nasal colonization were associated with a history of congestive heart failure, nursing home admission, and nasogastric tube feeding in the last 3 months.
