Risk factors for methicillin-resistant Staphylococcus aureus carriage among patients at admission to the surgical ward in a resource-limited hospital in Indonesia

This study aimed to identify risk factors for methicillin-resistant Staphylococcus aureus (MRSA) carriage among patients at admission to the surgery ward in a resource-limited hospital in Indonesia. A case–control study was performed including 65 MRSA carriage patients and 132 non-MRSA carriage patients screened at admission to surgery wards in a hospital in Malang, East Java. For MRSA screening, swabs were obtained from nares and throat, cultured in an enrichment broth followed by subculturing onto CHROMagar™ MRSA; suspected colonies were confirmed by polymerase chain reaction. Patients referred from other hospitals, patients transferred from the surgical acute care unit, patients that had a surgical procedure within 3 months before admission, and immunocompromised patients were more likely to be MRSA carriers at admission to the surgery wards. Selective MRSA screening of patients according to such risk factors at admission would efficiently detect MRSA carriers and may help control MRSA dissemination in surgery wards in limited-resource settings.
