Universal gown and glove use by health-care workers in ICU reduces MRSA 40 percent
Health-care workers' use of disposable gowns and gloves upon entering all patient rooms on an ICU, versus only in rooms on standard isolation protocol, helped reduce patient acquisition of MRSA by approximately 40 percent.
