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

Abstract

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