Abstract

Background: This study evaluated the effects of routine and additional environmental management with pulsed xenon ultraviolet (PXUV) disinfection in hospital operating rooms (ORs).
Methods: The study was conducted in 10 ORs of a hospital specializing in joint surgery with 174 hospital beds. We selected four surfaces with high frequency and one surface with low frequency of contact with the hands of operating room medical staff. After regular environmental management and additional PXUV disinfection from March to April 2020, a total of 250 specimens were collected by performing 50 culture tests on each selected surface.
Results: We found 4.8% (6/125) positive cultures after routine environmental management, but only 0.8% (1/125) after PXUV disinfection.
Conclusion: Although we could not conclusively evaluate the difference between routine and additional environmental management, PXUV disinfection showed a tendency to reduce environmental contamination.
