Sensitivities of Nasal and Rectal Swabs for Detection of Methicillin-Resistant Staphylococcus aureus Colonization in an Active Surveillance Program

Abstract
All medical and high-risk surgical patients were screened for methicillin-resistant Staphylococcus aureus colonization over 3.5 years. The sensitivities of nasal and rectal swabs were 68% and 62%, respectively. Naris and open-skin-site swabs detected 467 (74%) of 627 adult carriers identified. Rectal swabs detected an additional 160 (26%) carriers.
