Reducing Keyboard Contamination in an Acute-care Hospital: UV Angel Clinical Update

Share Article

Though not yet controlled for hospital Colostrum difficile infection (CDI) initiatives or antibiotic and proton-pump inhibitor use, there was an observed +51% reduction in the rate of CDIs in the ICU after UV Angel was deployed

Since fully implementing the UV Angel system, we have not cultured a single gram negative or drug resistant bacteria

In an ongoing Clinical Study conducted by an independent physician, Andrew Gostine, MD, MBA, at Presence Resurrection Medical Center (RMC) in Chicago, IL, UV Angel is evaluating the efficacy of its product and its disinfection protocol. This study is taking place in the medical and surgical intensive care units (totaling 30 beds) from May 2014 through October 2015 at a 360-bed, acute-care, academic medical center located in Chicago, Illinois.

To begin this study, Dr. Gostine first established a contamination baseline, discovering “95.1% of the keyboards to be contaminated with bacteria” (Table 1). Additionally, 22.2% of the keyboards were contaminated with HAI associated bacteria (Table 2).

The integration of 60 UV Angel devices in October of 2014 was met with a warm welcome by clinical staff. Initially, about 30 devices were implemented into RMC’s MICU. After learning about the additional protection the clinicians in the MICU had been afforded through these devices, the SICU demanded the same – believing that it would provide additional safety for their patients, families, and also for themselves. Dr. Gostine described the UV Angel system to work “remarkably well compared to standard hospital cleaning protocols.”

“Since fully implementing the UV Angel system, we have not cultured a single gram-negative or drug resistant bacteria” (Gostine, August 4, 2015; Table 3). This has included hundreds of randomly timed swabs of keyboards known to be significantly bacteria-ridden pre-intervention.

In addition to culturing and monitoring the efficacy of UV Angel’s reduction in keyboard contamination, Dr. Gostine has been collecting data with PRMC department of infection prevention regarding the rate of Colostrum difficile infections (CDI). Though not yet controlled for hospital CDI initiatives (i.e. hand-washing campaigns) or antibiotic and proton-pump inhibitor use, there was an observed +51% reduction in the rate of CDIs in the ICU during the year with UV Angel deployed.

UV Angel will be releasing its clinical study and pathogen reduction supplement, Evaluating the Effectiveness of the UV Angel Lights for Reducing Keyboard Contamination in an Acute-care Hospital: A Longitudinal Analysis in early 2016.
