US study shows power of HPV against HAIs

摘要

A study by infection control experts at the Johns Hopkins Hospital in the US has shown that robotic devices that disperse a bleaching agent into the air and then detoxify the disinfecting chemical are highly effective at killing hospital superbugs. The study on the use of hydrogen peroxide vaporisers has been published in the journal Clinical Infectious Diseases. The Johns Hopkins team placed the devices in single hospital rooms after routine cleaning to disperse a thin film of hydrogen peroxide vapour (HPV) across all exposed hospital equipment surfaces, as well as on room floors and walls. Results showed that the enhanced cleaning reduced by 64% the number of patients who later became contaminated with any of the most common drug-resistant organisms.
