colonization and surgical site infections among patients undergoing surgical fixation for acute fractures.

Objectives: To identify risk factors for methicillin-susceptible (MSSA) and methicillin-resistant (MRSA) nasal carriage and surgical site infection (SSI) among patients undergoing fracture fixation procedures who were included in a quality improvement protocol involving screening patients for nasal carriage and treating carriers with intranasal mupirocin and chlorhexidine bathing.

Design: Retrospective cohort study.
