摘要: Objectives: To determine whether environmental cleaning and contamination are associated with variation in the prevalence of methicillin-resistant Staphylococcus aureus (MRSA) between nursing homes. Design: Prospective study quality. Setting: Nursing home. Participants: Ten California homes. Measurements: homes were categorized into two groups based upon high low differences MRSA point admission (delta prevalence) from nares screenings home residents. Environmental infection control practices evaluated by culturing common area objects for MRSA, assessing removal intentionally applied marks visible only under ultraviolet (UV) light, administering surveys on cleaning. Results: Overall, 16% (78/500) positive, 22% (129/577) UV-visible removed. A higher proportion MRSA-positive was found (19%) than (10%) (P = .005). Infection policies varied, including frequency room (median 2.5 times daily, range 1�3 daily) time spent per 18 minutes, 7�45 minutes). In multivariate models, delta (odds ratio (OR) 2.8, P .005), less each (OR 2.9, < .001), less-frequent rooms 1.5, .01). Conclusion: Substantial contamination, practices, quality. greater prevalence, cleaning, room, which suggests that modifying may reduce burden homes.
