Does routine use of sporicidal disinfectants for all post-discharge hospital rooms reduce environmental contamination with Clostridioides difficile spores?

In a culture survey of 30 U.S. hospitals, rates of Clostridioides difficile spore contamination after cleaning and disinfection of non-C. difficile infection (CDI) rooms were lower in facilities using sporicidal disinfectants in all post-discharge rooms versus only in CDI rooms (3.6% versus 5.1%, respectively), but the difference was not statistically significant. Additional studies are needed to determine why spore contamination was not reduced more effectively and to develop interventions to ensure spore eradication in real-world settings.
