Universal treatment of all ICU patients for MRSA bacteria reduced all types of bloodstream infections by 44% and was more effective than screening patients first and treating those that test positive, according to a study in the New England Journal of Medicine. The study, which included 74 ICUs at 43 Hospital Corp. of America hospitals, found washing patients with antimicrobial soap and giving them a nasal antibiotic ointment reduced MRSA-positive cultures in the ICU by 37%.
