The study was varied out in contaminated patient rooms in an acute-care tertiary hospital in North Carolina from Jan. 21 through Sept. 21, 2009. In the study, sheets contaminated with the aforementioned pathogens were placed in direct line of sight of the UV device and behind objects. Following timed exposure, specific sites of the patient rooms were sampled before and after UV irradiation to measure the presence of the pathogens.
Results showed UC radiation reduced the counts of the vegetative bacteria on surfaces by more than 99.9 percent within 15 minutes and C. difficile on surfaces by 99.8 percent within 50 minutes. UV radiation also resulted in a decrease in total CFUs over a 15-minute duration.
