The annual incidence of methicillin-resistant Staphylococcus aureus per 1,000 patient days and the submission rate of bacteriological cultures in the urology ward, 2000-2010. (A) Annual incidence of MRSA colonization or infection per 1,000 patient days. (B) Annual incidence of MRSA colonization or infection per 1,000 patient days in the urology ward. (C) Annual incidence of clinically significant MRSA infection per 1,000 patient days in the urology ward. (D) Annual submission rate of bacteriological culture in the urology ward. Although the incidence of MRSA increased throughout the entire hospital, it decreased significantly in the urology ward (A). In the urology ward, the incidence of acquired MRSA decreased significantly, whereas the incidence of imported MRSA did not change over time (B). A significant decrease in the incidence of clinically significant MRSA infection over time was found (C). After introducing surveillance cultures in 2007, the submission rate of bacteriological cultures increased in 2008 (D).
