WASHINGTON — New research demonstrates that daily cleaning of high-touch surfaces in isolation rooms of patients with Clostridium difficile (C. diff) or methicillin-resistant Staphylococcus aureus (MRSA) significantly reduces the rate of the pathogens on the hands of healthcare personnel, according to a press release.
The findings underscore the importance of environmental cleaning for reducing the spread of difficult-to-treat infections and are published in the October 2012 issue of Infection Control and Hospital Epidemiology, the release stated.
According to the release, researchers from the Cleveland Veterans Affairs Medical Center conducted a prospective, randomized trial comparing regular cleaning protocols of housekeeping staffs with daily disinfection of high-touch surfaces performed by researchers in 34 C. diff and 36 MRSA isolation rooms.
The study assessed hand contamination of physicians, nurses and research staffs six to eight hours after disinfection procedures, the release noted.
In rooms with daily disinfection, there were significant reductions in the amount and frequency of pathogens on the hands of investigators and healthcare personnel caring for the patients, the release added.
"These findings add to the growing body of evidence supporting environmental cleaning and disinfection as an important infection control strategy. The intervention was simple, inexpensive and well-accepted by patients and staffs," said Sirisha Kundrapu, a lead author of the study.
