BackgroundSurgical site infection (SSI) is a costly complication leading to increased resource use and patient morbidity. We hypothesized that postdischarge SSI results in a high rate of preventable readmissions.MethodsWe used our institutional American College of Surgeons National Surgical Quality Improvement Program database to identify patients undergoing general surgery procedures from 2006 to 2011.ResultsSSIs developed in 10% of the 3,663 patients who underwent an inpatient general surgical procedure. SSI was diagnosed after discharge in 48% of patients. Patients with a diagnosis of SSI after discharge were less likely to have a history of smoking (15% vs 28%, P = .001), chronic obstructive pulmonary disease (3% vs 9%, P = .015), congestive heart failure (0% vs 3%, P = .03), or sepsis within 48 hours preoperatively (17% vs 32%, P = .001) compared with patients diagnosed before discharge. Over 50% of the patients diagnosed with SSI after discharge required readmission.ConclusionsA diagnosis of SSI after discharge is associated with a high readmission rate despite occurring in healthier patients. We propose discharge teaching improvements and a wound surveillance clinic within the first week may result in a decreased readmission rate.Copyright © 2014 Elsevier Inc. All rights reserved.
