Abstract
The number of patients with methicillin-resistant Staphylococcus aureus (MRSA) before and after discontinuing placement of patients into private rooms was determined. The mean monthly number of patients with MRSA decreased from 34 to 22, and the proportion of S aureus isolates that were MRSA decreased from 34% to 20%. We found no evidence that failure to isolate patients with MRSA resulted in an increased prevalence of MRSA.
