Evidence that near-patient surfaces in hospitals could host methicillin-resistant S. aureus (MRSA) was put forward by Boyce et al.in 1997 (46). This study also showed that health care staff couldcontaminate their gloves by handling or touching sites in closeproximity to patients colonized with MRSA. This contrasts with astudy published 16 years later, showing that thorough cleaningfailed to reduce health care worker gown and glove contaminationafter caring for patients with MRSA (and multidrug-resistantAcinetobacter spp.) (47). While the risk of health care worker contaminationwith MRSA remains undetermined therefore, studieshave shown that basic cleaning eliminates MRSA from the wardenvironment, with measured benefit for patients. Over a 14-month period, 13 patients acquiredMRSAon a dermatology warddespite routine control measures (48). Extensive environmentalculturing identified MRSA from the patients’ communal showerand a blood pressure cuff, with indistinguishableDNAtyping patternsfound from both patient and environmental isolates. Casesdiminished after enhanced cleaning of shared common areas andchanging the blood pressure cuff between patients (48).
