San Diego – October 9, 2015 – As hospitals face increasing pressure to reduce their hospital acquired infection (HAI) rates, evidence continues to mount that ultraviolet (UV) disinfection can destroy the pathogens that cause infections. Hospitals using Xenex pulsed xenon Full-Spectrum™ UV room disinfection technology have shown, in multiple peer-reviewed published studies, reductions in HAI rates greater than 50 percent.  The Xenex Germ-Zapping Robot™ is the only UV disinfection technology that has been shown, in multiple peer-reviewed published outcome studies, to help hospitals reduce HAI rates.

Xenex will discuss its 14 peer-reviewed studies, including seven HAI reduction studies, in Booth 325 during IDWeek, held October 7-11, 2015 in San Diego. The newest peer-reviewed study, which shows a 57 percent decrease in Clostridium difficile (C.diff) infection rates when a Long Term Acute Care (LTAC) facility utilized Xenex germ-zapping robots for room disinfection, was recently published in the American Journal of Infection Control (AJIC).

Also at the IDWeek conference, the Duke Infection Control Network (DICON) began releasing information about the results of its two-year study “The Benefits of Enhanced Terminal Room (BETR) Disinfection.” The BETR Disinfection study has not yet been published but Dr. Deverick Anderson will present the findings during IDWeek. According to the abstract, the study examined the impact of several methods of enhanced terminal room disinfection, including UV disinfection, as a means to prevent healthcare-associated infections. The study found that utilizing UV disinfection technology after isolation room discharges reduced the risk of transmission of the microorganisms that cause infections.

“The BETR Disinfection study is great news for UV disinfection because it further validates the fact that UV disinfection works,” said Dr. Mark Stibich, Chief Scientific Officer of Xenex. “We applaud Dr. Anderson and his team for including UV disinfection in this study and look forward to further information about the results after the data has gone through the peer review process.”

According to a BETR Disinfection abstract published in 2013, the mercury UV devices utilized in the study required a median cycle time of 52 minutes for C.difficile spore disinfection. During the two-year period that the BETR Disinfection study was being conducted, numerous hospitals using Xenex pulsed xenon UV room disinfection technology reported significant reductions in their infection rates and published those HAI rate reduction results in peer-reviewed literature. Hospitals using Xenex pulsed xenon UV systems are able to disinfect dozens of rooms per day and bring down the facility’s bioburden, resulting in lower infection rates. Xenex is effective facility-wide because the robots work quickly and can be easily assimilated into a hospital’s existing operations and HAI reduction strategy.

The new pulsed xenon UV study published in AJIC demonstrates how an urban LTAC facility was able to decrease its C.diff infection rates by 57 percent after it began using Xenex’s pulsed xenon UV room disinfection system to disinfect communal living areas and patient rooms. In this study, the Xenex robots were used in five-minute positions in patient rooms to impact C. diff infection rates.

MD Anderson Cancer Center, the Central Texas Veterans Health Care System, Cooley Dickinson Health Care (an affiliate of Massachusetts General Hospital and Partners HealthCare System) and other hospitals have published 14 studies providing evidence of the Xenex robot’s efficacy in highly regarded scientific journals that include AJIC, the Journal of Infection Prevention, ICHE and BMC Infectious Diseases. Xenex robots are in more than 300 hospitals, Veterans Affairs (VA), Department of Defense (DoD), long term acute care and skilled nursing facilities, and outpatient surgery centers in the U.S., Canada, Europe and Africa.
