Summary: | To determine rates of surgical site infection (SSI) with and without an abdominal closure protocol for gynecologic oncology patients undergoing abdominal hysterectomy.
Consecutive patients were identified using CPT codes who underwent total abdominal hysterectomy by gynecologic oncologists at a tertiary care center from January 1, 2015 to December 31, 2019, and stratified by use of the abdominal closure protocol. Demographic, perioperative, and pathologic variables were collected. Fisher's exact and Chi squared tests were used for categorical variables, logistic regression and student t-tests for continuous variables. Multiple logistic regression was used to analyze the relationships between these variables, use of the closure protocol, and development of SSI.
739 patients were included over the study period (n = 393 pre-implementation, n = 346 post-implementation of the abdominal closure protocol,). Baseline demographics including ASA score, BMI, diabetes, and smoking were similar between these groups (P = 0.14–0.94). The rate of SSI within 30 days was 5.9% (23/393) in the pre-protocol group and 8.1% (28/346) under the abdominal closure protocol (P = 0.25). On univariate analysis, factors associated with SSI were BMI >40, diabetes, bowel resection, ASA score 3 or 4, hypertension, and contaminated wound class (uOR 2.31–4.09). On multivariate analysis BMI >40, diabetes, and bowel resection remained independent risk factors (aOR 2.27–2.99), with the closure protocol not achieving significance (aOR 1.43, 95% CI 0.79–2.59). There were no potentially high-risk sub-groups in whom the closing protocol showed benefit.
The abdominal closure protocol in isolation did not decrease SSI in those undergoing TAH by a gynecologic oncologist.
•An abdominal closure protocol in isolation did not decrease the rate of SSI during oncologic total abdominal hysterectomy.•SSI rates after hysterectomy remain high, further research into alternative methods to decrease the rates of SSI are needed.•Institutions which already implemented other SSI reduction bundle steps may forego the addition of a separate closing tray. |
