Although international efforts to standardize metrics for monitoring methicillin-resistant Staphylococcus aureus (MRSA) in healthcare settings are in progress, the national MRSA benchmark data is still lacking in Japan. We measured two MRSA surveillance indices at seven tertiary care hospitals, based on the Multidrug-Resistant Organism & Clostridium difficile Infection Module published by the Centers for Disease Control and Prevention. During the 1-year study period, the MRSA infection or colonization incidence rate was 0.26 per 1,000 patient-days, whereas the MRSA bloodstream infection incidence rate was 0.04 per 1,000 patient-days. The 30-day all-cause mortality rate per 100 MRSA bacteremia cases was 20.3%. As the National Action Plan on Antimicrobial Resistance is launched, we believe this study provides a reference regarding MRSA incidence in Japanese healthcare settings.
