Abstract

Environmental contamination of hospital rooms is well recognized as a reservoir for highly resistant nosocomial pathogens such as methicillin-resistant Staphylococcus aureu (MRSA) and vancomycin-resistant Enterococcus (VRE), which can be transferred to patients through contact with healthcare providers and contaminated surfaces. Numerous studies dedicated to environmental cleaning and disinfection have found promising results with several novel technologies, including vaporized hydrogen peroxide and ultraviolet over-head lighting or wands. We conducted a pilot study of one such device, the Sterilray Disinfection Wand (Healthy Environment Innovations), a handheld ultraviolet (UV) room decontamination wand. The Sterilray device claims to generate UV radiation in the far-UV spectrum (185-230 nm), resulting in the rapid killing of contaminant bacteria. The goal of this pilot was to collect preliminary data on the efficacy of this device in reducing surface contamination, particularly of common nosocomial pathogens, in an active hospital setting.
