Healthcare associated infections (HAIs) remain a serious and potentially lethal problem for patients and a significant source of unreimbursed expense for hospitals. High-touch surfaces in patient environments are well-established sources of infections, but traditional cleaning regimens fail to eliminate many pathogens.

A growing number of healthcare organizations are turning to new technologies to complement standard cleaning protocols. Most of these technologies have been shown to kill microorganisms in the laboratory setting. It is known that these tests do not reflect the real-world environment. When evaluating these technologies, it is essential to review the studies published in the scientific literature that give evidence of the technology’s ability to reduce actual rates of HAIs.

Pulsed xenon ultraviolet light disinfection, introduced to the healthcare market in 2010 by Xenex Disinfection Services, is the only environmental disinfection technology with reported HAI rate reductions in multiple peer reviewed research articles. The Xenex
system kills a broad range of pathogenic microorganisms, including hardy C. diff spores, on high-touch surfaces within 10 to 15 minutes per room. Hospital environmental service staff are easily trained to use the Xenex robot.

This paper discusses the peer reviewed research that has evaluated the effectiveness of the Xenex technology and the financial benefits associated with the adoption of this technology.
