Utilization and impact of a pulsed-xenon ultraviolet room disinfection system and multidisciplinary care team on Clostridium difficile in a long-term acute care facility.

Health care-associated transmission of Clostridium difficile has been well documented in long-term acute care facilities. This article reports on 2 interventions aimed at reducing the transmission risk: multidisciplinary care teams and no-touch pulsed-xenon disinfection. C difficile transmission rates were tracked over a 39-month period while these 2 interventions were implemented. After a baseline period of 1 year, multidisciplinary teams were implemented for an additional 1-year period with a focus on reducing C difficile infection. During this time, transmission rates dropped 17% (P = .91). In the following 15-month period, the multidisciplinary teams continued, and pulsed-xenon disinfection was added as an adjunct to manual cleaning of patient rooms and common areas. During this time, transmission rates dropped 57% (P = .02). These results indicate that the combined use of multidisciplinary teams and pulsed-xenon disinfection can have a significant impact on C difficile transmission rates in long-term care facilities.
