Worldwide incidence of surgical site infections in general surgical patients: a systematic review and meta-analysis of 488,594 patients.

Surgical site infections (SSI) are a common, yet largely preventable, complication of surgery which can result in increased length of stay and hospital readmission. In this review of 57 studies, the cumulative incidence of SSI was 11% in adult general surgical patients and was associated with increased length of stay (with variation by types of surgery).
