Evaluation of Infection Prevention of Clostridium difficile Infection by Potassium Peroxymonosulfate Disinfectant Cleaner

Abstract

The number of cases of Clostridium difficile infection (CDI) had increased in our hospital since November 2013. As the outbreak of horizontal infection of CDI was strongly suspected, we introduced potassium peroxymonosulfate cleaner (RST) in May 2014. The incidence of CDI was significantly reduced after beginning to use RST (May 2014 - December 2015) compared to the pre-introduction period (January 2012 to April 2014). The results of this study suggest that environmental improvement using RST is a useful approach for suppressing horizontal infection of Clostridium difficile.
