Les infections à Clostridioides difficiles (ICD) sont à l’origine d’une morbidité et d’une mortalité importantes dans les établissements de santé du monde entier. Nous avons examiné l’utilisation d’un système de désinfection au peroxyde d’hydrogène en aérosol (aHP) pour réduire les taux d’ICD.

Background Clostridioides difficile infections (CDI) cause significant morbidity and mortality in healthcare facilities worldwide. We examined the use of an aerosolized hydrogen peroxide (aHP) disinfection system for reduction of CDI rates. Methods We conducted a retrospective analysis of CDI rates at an acute care facility over a 10-year period. The first 5-year period investigated the before and after implementation of an aHP system followed by another 5-year period of continued use on CDI rates. Results The before and after period showed a reduction in CDI rates from 4.6 per 10,000 patient days down to 2.7 per 10,000 patient days after implementation (P < .001). The second study period for the continued aHP use exhibited a consistent decrease in CDI rates to 1.4 per 10,000 patient days at the end of the study. Conclusions The addition of a touchless aHP whole room disinfection system as part of terminal cleaning resulted in a significant reduction in CDI rates that have been sustained year after year.
