An infection control team (ICT) was organized in our hospital in 2005. Before organizing the ICT, an infection control nurse had performed surveillance of multi-drug microorganisms as an additional duty. After organizing the ICT, information about screening and detection of multi-drug microorganisms were sent to all members of the ICT, who immediately started to perform this duty. Until the start of the ICT, many multi-drug microorganisms had been detected. The present study investigated the effect of surveillance of methicillin-resistant Staphylococcus aureus (MRSA) and multi-drug resistant Pseudomonas aeruginosa (MDRP) in our hospital between 2005 and 2009. After starting the ICT, the detection rate of MDRP fell to near zero and that of MRSA was reduced to one third. Detection of MDRP was limited to the fields of urinary tracts in our hospital; as decrease in the ratio of MDRP was thought to be easier and more effective than that of MRSA. The detection rate of MRSA in our hospital was affected by the rate of introduction of MRSA into our hospital from the community. To decrease the detection rate of MRSA, community-based surveillance and efforts should be started.
