Clinical Studies

Reducing Clostridium difficile Infection among Hematology-Oncology Patients Using Ultraviolet Germicidal Irradiation for Terminal Room Disinfection

D. Pegues, C. Gilmar, M. Denno and S. Gaynes (University of Pennsylvania); CDC Epicenters Program

Medical personnel in lab coat and gloves


Deployment of the Optimum-UV® System resulted in a 25% decrease in Clostridium difficile infection (CDI) rates on the study units as compared with the baseline period. An estimated $134,568 to $191,604 in annual direct medical costs were averted by preventing 21 cases of CDI on the study units.
