Endemic methicillin-resistant Staphylococcus aureus in a special care baby unit: a 2 year review.

During January 1987, methicillin-resistant Staphylococcus aureus (MRSA) was isolated for the first time from a baby admitted to the special care baby unit of a large metropolitan hospital. Over a 2 year period, of 1574 babies admitted to the unit, at least 573 (36.4%) became colonized with the organism. Only nine (1.6%) developed significant infectious morbidity and one baby died. Minor infections occurred in a further 35 (6.1%). The outbreak remained uncontrolled despite rigid infection control measures. Subsequent emphasis on hand washing, in-service education and provision of weekly review of the MRSA colonization rates have failed to eliminate the organism from the unit.
