Can pulsed xenon ultraviolet light systems disinfect aerobic bacteria in the absence of manual disinfection?

Am J Infect Control. 2015 Apr 1;43(4):415-7. doi: 10.1016/j.ajic.2014.12.012. Epub 2015 Feb 10.


Whereas pulsed xenon-based ultraviolet light no-touch disinfection systems are being increasingly used for room disinfection after patient discharge with manual cleaning, their effectiveness in the absence of manual disinfection has not been previously evaluated. Our study indicates that pulsed xenon-based ultraviolet light systems effectively reduce aerobic bacteria in the absence of manual disinfection. These data are important for hospitals planning to adopt this technology as adjunct to routine manual disinfection.

Keywords: Aerobic bacteria colony count; Enhanced manual cleaning; Hospital acquired infections; No-touch disinfection.
