Study: Deep cleaning lowers MRSA risk
Deep cleaning of intensive care units can help lower the risk of drug-resistant bacteria, U.S. researchers say.
The study finds an enhanced cleaning protocol helped lower methicillin-resistant Staphylococcus aureus infection among those exposed to a prior occupant with MRSA to 1.5 percent out of 1,443 patients -- down from the 3.9 percent of out of 1,454 patients before the enhanced cleaning.
The study involved more than 13,000 hospital stays in 10 Boston intensive care units. Routine admission and weekly screenings for MRSA and vancomycin-resistant Enterococci were conducted both in September 2003 to April 2005 before the cleaning intervention and during the intervention -- September 2005 to April 2008.
The findings were presented at the Society for Healthcare Epidemiology of America meeting in San Diego.
