Background

In spite of gains made in the United Kingdom to reduce the burden of some infections, infection prevention continues to be a challenge and decontamination of patient care areas has become a more vital part of infection control programs, particularly for C. diff and norovirus. This study evaluated the effectiveness of a pulsed Xenon UV disinfection device at Queens Hospital in reducing the contamination of high touch surfaces.

Results

The study found that standard terminal cleaning (manual cleaning with chemical disinfection) did not adequately remove microbial contamination. The pulsed Xenon UV system significantly reduced microorganisms from high touch surfaces further reducing the number of rooms still contaminated after terminal cleaning by at least half for all 5 surfaces tested.
