Use of Ultraviolet Irradiation in Addition to Commonly Used Hospital Disinfectants or Cleaners Further Reduces the Bioburden on High-Touch Surfaces

摘要

The reduction in microbial bioburden achieved by terminal disinfection in a hospital may vary considerably by type of disinfectant or cleaner and by environmental service (EVS) personnel. This study estimated whether supplemental ultraviolet (UV) irradiation after disinfection or cleaning reduced bioburden and whether the supplemental effect persisted after adjusting for disinfectant or cleaner type and EVS personnel.
