Reduction of Hospital Environmental Contamination Using Automatic UV Room Disinfection, St. Mary’s General Hospital, InfectionControl.tips, August 2016.
This study was designed to gain an understanding of the number of disinfection cycles per day and to compare differences in microbial loads between rooms that have and do not have automated UV disinfection units. General microbial contamination levels were monitored to evaluate the overall efficacy of UV disinfection. No attempt was made to monitor epidemiologically important pathogens or infection rates.
Surface sampling in four patient bathrooms, an equipment storage room, and a soiled utility room showed that the use of Sanuvox Aseptix 1 automated UV disinfection devices significantly reduced microbial contamination. The frequency of heavily contaminated surfaces, characterized by TNTC samples, was reduced by ~65% overall during the periods when the UV systems were active and door closings ranged from 27– 44%, compared to periods when the UV systems were not active.
One of the major learnings of the study is that it is important when engineering a solution to fully automate every step. In the case of AutoUV, using automatic door closers rather than relying on signage and training to have people close doors manually would increase effectiveness from 65% of the time to close to 100% of the time.

This study found that point-of-use ROS water generated in a hand hygiene sink was as effective as soap and water for decontaminating hands. It also found >99% reduction in bacterial growth in the sink drain.

Support from Queens Park & Parliament Hill - We have been continuing the effort to lobby both MPPs and MPs for funding support both for CHAIR and hospitals infection control technology purchases. In the last 3 months MP Bryan May, MPP Kathryn McGarry, MPP Daiene Vernile, MPP Katherine Fife, and the Minister of health & Long Term Care, Dr. Eric Hoskins have all met with board members at the CHAIR hospital room at the Class 1 Inc. Cambridge manufacturing facility.
We are continuing to hear about the positive impact on participants in the bone marrow transplant (BMT) project at Vancouver General Hospital in which CHAIR CANADA has helped source engineered product solutions. This is a two-year pilot study that will tackle reducing the risk of infection in BMT patients using several complimentary and novel approaches.
CHAIR worked with Class 1, the University of Waterloo and Kitchener’s St Mary’s General Hospital, to complete a three-month trial in October using ultraviolet lights in 2 patient washrooms. A Report is soon to be released citing the successful impact of UV in this study.
CHAIR Canada Participation at Innovative Project at Lions Gate Hospital, North Vancouver - CHAIR Canada was able to coordinate the initial testing of a wall mounted Ultraviolet C (UV-C) disinfecting system at Lions Gate Hospital (LGH) in North Vancouver.
