Using Pulsed Xenon Ultraviolet to Decrease Contamination in Operating Rooms During Terminal Cleaning
This study assesses the level of bacterial contamination in a terminally-cleaned OR as compared with a modified turnover (between case) clean plus PX-UV. Five surfaces were selected for sampling after terminal cleaning in 16 ORs and after Turnover Clean+PX-UV disinfection in 22 ORs for a total of 190 samples. Contamination levels for the two cleaning methods were compared using negative
binomial regression. The Turnover Clean+PX-UV method was shown to be superior to standard terminal cleaning, producing a 62% reduction in microbial load in the OR.
