NEW Rapid Hospital Room Decontamination Using Ultraviolet (UV) Light with a Nanostructured UV-Reflective Wall Coating

William A. Rutala, PhD, MPH Maria F. Gergen, MT(ASCP); Brian M. Tande, PhD David J. Weber, MD, MPH
The reflective wall coating provided the following time reductions for decontamination: for methicillin-resistant Staphylococcus aureus, from 25 minutes 13 seconds to 5 minutes 3 seconds (P ! .05), and for Clostridium difficile spores, from 43 minutes 42 seconds to 9 minutes 24 seconds (P ! .05)..

Decontamination of Targeted Pathogens from Patient Rooms Using an Automated Ultraviolet-C-Emitting Device

Deverick J. Anderson, MD, MPH; Maria F. Gergen, MT (ASCP); Emily Smathers, MPH;2 Daniel J. Sexton, MD; Luke F. Chen, MBBS, MPH; David J. Weber, MD, MPH; William A. Rutala, PhD, MPH
Our data confirm that automated UV-C-emitting devices can decrease the bioburden of important pathogens in realworld settings such as hospital rooms.

Are Room Decontamination Units Needed to Prevent Transmission of Environmental Pathogens

William A. Rutala, PhD, MPH; David J. Weber, MD, MPH
There is now ample evidence that no-touch systems such as UV-C light can reduce environmental contamination with healthcare-associated pathogens.

Terminal Decon of Patient Rooms using TRU-D

John M. Boyce, MD; Nancy L. Havill, MT; Brent A. Moore, PhD
The mobile UV-C light unit significantly reduced aerobic colony counts and C. difficile spores on contaminated surfaces in patient rooms.

Evaluation of Automated UV Device (Tru-D) for Decon of C-Diff

Michelle M Nerandzic, Jennifer L Cadnum, Michael J Pultz and Curtis J Donskey
Environmental surfaces play an important role in transmission of healthcare-associated pathogens. There is a need for new disinfection methods that are effective against Clostridium difficile spores, but also safe, rapid, and automated.

Decontamination with Ultraviolet Radiation (Tru-D) to Prevent Recurrent Clostridium difficile infection in a Long-Term Care Facility; ICHE May 2012

Brett Sitzlar, BS; Ravy K Vajravelu, BS; Luch Jury, NP; Curtis J Donskey, MD; Robin L.P. Jump, MD, PhD
Routine use of (Tru-D) to decrease the environmental burden of pathogens is a feasible addition to current infection control and housekeeping measures help to reduce rates of CDI among patients in hospitals and LTCFs

Elimination of Clostridium difficle by illumination

Ann Marie Pettis, RN, BSN, CIC; Mark Shelly, MD; Celeste Andrews, RN,MSN,CIC; Franklin Allen
In the quarter following implementation of UV-C the CDI rate was 1.6 per 1000 patient days. In the next quarter it dropped further to 0.8. This was the lowest rate documented in over 10 prior quarters. 14 hospital onset cases occurred in the 2 months prior to UV-C compared to 8 cases occurring in the 2 months after implementing UV-C. Based on a reduction in CDI Administration supported the purchase of the machine once the free trial was over. The machine continues to be used in a “clean sweep” fashion, treating an entire unit in one time frame.
