BackgroundInstitutional protocols for preincisional antibiotic prophylaxis can standardize care and improve outcomes. However, challenges remain in compliance with such protocols for urgent or emergent operations. We hypothesized that compliance with an institutional protocol for antibiotic prophylaxis for appendectomy for appendicitis in pediatric patients results in reduced surgical site infections (SSIs) after simple appendectomy.MethodsThis retrospective study assessed all pediatric patients (≤18 y) who underwent appendectomy for confirmed simple appendicitis at a tertiary children's hospital between 2012 and 2015. Demographic, admission, and outcome data were recorded. Compliance with the protocol was assessed. Univariate analyses were performed to identify factors associated with any SSI and protocol noncompliance.ResultsOverall compliance with antibiotic prophylaxis occurred in 590 of 697 patients (85%). Compliance was high with timing (91%), spectrum (95%), and protocol-recommended drug (87%). Admission antibiotics alone were administered in 65 patients (9%), preincisional antibiotics alone in 254 patients (36%), and both in 378 patients (55%). Patients included in the analysis received a median of 2 (range 1-6) doses of antibiotics preoperatively. Ten patients (1.4%) developed an SSI. Only receipt of any antibiotics within an hour of incision was associated with decreased odds of SSI (odds ratio 0.22, 95% confidence interval 0.06-0.87). No factors were associated with noncompliance.ConclusionsAn institutional appendicitis protocol yields high compliance with prophylactic antibiotic administration and associated low SSI rates, but at a cost of antibiotic over-administration. Further efforts are necessary to sustain compliance while also practicing appropriate antibiotic stewardship.Copyright © 2017 Elsevier Inc. All rights reserved.
