Postdischarge decontamination of MRSA, VRE, and Clostridium difficile isolation rooms using 2 commercially available automated ultraviolet-C–emitting devices

Efficacy of an automated ultraviolet C device in a shared hospital bathroom

“…Portable UVC devices have been used as effective decontamination tools and have been shown to be more effective than manual cleaning alone. 5 Recently, UVC significantly outperformed manual cleaning using accelerated hydrogen peroxide in the removal of methicillin-resistant Staphylococcus aureus, vancomycin-resistant enterococci, and Clostridium difficile. 5 Similar results have been seen with the use of short exposure time UVC devices (5-10 minutes), significantly reducing C difficile and methicillin-resistant S aureus levels.…”

“…One costeffective decontamination tool used in hospitals as an adjunct to traditional cleaning and disinfection is ultraviolet C (UVC) irradiation. [4][5][6] The goal of this study was to evaluate the incremental antimicrobial effect of an automated, permanently installed UVC device with a short run time (5 minutes) on surface and airborne bacterial levels in a shared patient bathroom (BR).…”

Hospital Infection Control: Clostridioides difficile

“…87 More recently, several no-touch adjunct measures have shown promise, particularly those based on UV light or hydrogen peroxide vapors or aerosols. [88][89][90][91][92] While all enhanced strategies require specialized equipment and cannot be conducted with the patient in the room, hydrogen peroxide vapor and aerosol-based systems also require that the room be sealed during treatment. In contrast, UV light systems are easier to deploy and are supported by one of the largest cluster-randomized trials to assess terminal room cleaning methods, to date.…”

Muddy puddles - the microbiology of puddles located outside tertiary university teaching hospitals

“…Several recent studies have identified that hospital floors may be heavily contaminated, but traditionally within Infection Prevention and Control (IPC) practice, this is not considered significant, as floors are usually non‐touch surfaces (Wong et al . ; Cura Della Redazione ) and therefore hospital floors are generally cleaned with detergent, but are not disinfected, except in high risk areas. The absence of adequate floor disinfection may lead to the transmission of nosocomial pathogens.…”
