Significant Decreases in C. diff Infection Rates with Pulsed Xenon UV

Impact of pulsed xenon ultraviolet light on hospital-acquired infection rates in a community hospital

Published: American Journal of Infection Control, March 2016


The Centers for Disease Control and Prevention have estimated that as many as 722,000 hospital-acquired infections were occurring each year. In exploring solutions, the CDC broadened its efforts to better understand the role that contaminated surfaces play in disease transmission given that substantial evidence exists that multiple drug-resistant organisms regularly contaminate air and surfaces within patient rooms. This study explored the impact of adding a pulsed Xenon UV disinfection system as adjunct to traditional cleaning methods in South Seminole Hospital, a 126 surgical bed hospital. The pulsed Xenon UV system was used in all ICU rooms when patient was discharged or transferred and in non-ICU rooms where the patient had C. difficile.


The study found a 29% reduction of VRE+MRSA+C. diff infection rates facility wide, particularly with a 41% decrease in C. diff infections. Implementation of the pulsed Xenon UV disinfection system also resulted in a 56% reduction in MRSA infections and 87% reduction in VRE in ICU patients.
