When should contact precautions be discontinued for patients with methicillin-resistant Staphylococcus aureus?

When to discontinue contact precautions for patients with methicillin-resistant Staphylococcus aureus (MRSA) remains unresolved and policies vary between hospitals. We prospectively performed admission active surveillance cultures on patients known to have been MRSA positive for at least 1 year to determine the proportion who remained positive. The proportion of patients with MRSA who remained positive was 19.9%; however, this significantly decreased over time, particularly after 5 years.
