Reduction in MDRO and C. diff Rates

Implementation and impact of ultraviolet environmental disinfection in an acute care setting

Published: American Journal of Infection Control, June 2014


Multiple drug-resistant organisms (MDRO) and C. diff (CD) can cause significant problems in health care. This retrospective study evaluated the effectiveness of utilizing UV light to help reduce the MDROs and CD at the Westchester Medical Center, a 643-bed academic medical center. The use of UV disinfection was added to cleaning protocols after standard cleaning was completed at discharge in rooms where contact precautions were in place or other high-risk areas.


The study reported a 20% decrease in hospital-acquired infection rates for MDRO and CD during the 22-month UV disinfection period, as compared to the 30-month pre-implementation period.
