Abstract
BACKGROUND/ PURPOSE: Surgical wound class (SWC) is used to risk-stratify surgical site infections (SSI) for quality reporting. We previously demonstrated only 8% agreement between hospital-based SWC and diagnosis-based SWC for acute appendicitis. We hypothesized that education and process-based interventions would improve hospital-based SWC reporting and the validity of SSI risk stratification. METHODS: Patients (<18 years old) who underwent appendectomies for acute appendicitis between January 2011 and December 2013 were included. Interventions entailed educational workshops regarding SWC for perioperative personnel and inclusion of SWC as a checkpoint in the surgical safety checklist. Thirty-day postoperative SSIs were recorded. Chi-square, Fisher's exact test, and kappa statistic were utilized. RESULTS: 995 cases were reviewed (pre-intervention=478, post-intervention=517). Weighted interrater agreement between hospital-based and diagnosis-based SWC improved from 50% to 81% (p<0.01), and weighted kappa increased from 0.16 (95% CI 0.004-0.03) to 0.29 (95% CI 0.25-0.34). Hospital-based dirty wounds were significantly associated with SSI in the post-intervention period only (p<0.01). CONCLUSIONS: Agreement between hospital-based SWC and diagnosis-based SWC significantly improved after simple interventions, and SSI risk stratification became consistent with the expected increase in disease severity. Despite these improvements, there were still substantial gaps in SWC knowledge and process.
