In a poster abstract presented at IDWeek 2016, researchers presented findings on the effectiveness of Tru-D in reducing patient infections. Short for “total room ultraviolet disinfection,” Tru-D guarantees complete room disinfection operating from a single position with a single cycle of UVC light energy.

According to the researchers, in the past 15 years, much has been discovered on the role of the environment in the transmission of infectious diseases. In fact, more recently, researchers have discovered that the use of antibiotics can promote C. diff proliferation and the number of C. diff spores that are shed into the local environment. Therefore, it has been determined that disinfection of all surfaces in a health care facility is critical in reducing multidrug-resistant organisms (MRDOs) in the environment. In the poster abstract presented at IDWeek, “Microbial Load on Environmental Surfaces: The Relationship Between Reduced Environmental Contamination and Reduction of Healthcare-Associated Infections,” researchers proved that a combination of manual cleaning and Tru-D’s measured dose UV light energy can lead to a reduction of 94 percent of MDROs and a 35 percent decrease in infection rates.

“Sometimes we label areas high risk – tray tables, sink, side rails, call box, chair, etc. – however, no one has ever identified these objects as more likely to be involved in transmission of disease,” said Dr. William A. Rutala, one of the abstract’s researchers in his presentation “Role of the Environmental Surfaces in Disease Transmission: ‘No Touch’ Technologies Reduce HAIs” at the 2016 Association for the Healthcare Environment Conference. “We absolutely do not know what is more high risk, so we have to focus on all surfaces. Given this data, all room surfaces must be disinfected.”

Tru-D’s UV disinfection robot ensures total room disinfection, eliminating harmful pathogens such as C. diff, MRSA and VRE in a single cycle from a single position. Used in terminal room disinfection, Tru-D is brought into a room after the EVS staff cleans using traditional methods. Tru-D then operates from a single position and administers a single cycle of UVC light, destroying up to 99.9 percent of pathogens that can remain behind.
