    AbstractSurgical site infections (SSI) are associated with increased morbidity and mortality rates. This study aimed to investigate the ability of perioperative oral management (POM) to reduce the risk of SSI in abdominal surgery Real-world data collected from 16 university hospitals in Japan were reviewed. The medical records of consecutive 2782 patients (1750 men and 1032 women) who underwent abdominal surgery under general anesthesia at 16 university hospitals were retrospectively reviewed. Detailed information about SSI was assessed and compared between patients with and without POM in univariate and multivariate analyses. SSI were observed in 275 patients (incidence rate:9.9%), and POM was administered to 778 patients (28.0%). Univariate analyses revealed that diabetes mellitus, Eastern Cooperative Oncology Group performance status, American Society of Anesthesiologists classification, surgical site, preoperative Prognostic Nutritional Index score, POM, extent of surgery, operation time, and intraoperative blood loss were significantly associated with postoperative SSI (Chi-square or Mann-Whitney U test, P < .01). Multivariate analysis revealed that POM had significant preventive effects against postoperative SSI (estimate: -0.245, standard error: 0.080, P < .01). Surgical site, American Society of Anesthesiologists classification, and operation time were also significant and independent clinical predictors of SSI. The analysis of real-world data from 16 university hospitals revealed that, regardless of the content and degree of the problem, the addition of POM has significant beneficial effects in reducing the risk of SSI in patients who undergo abdominal surgery. Medical records from each hospital and data from the Health Care Payment Fund were collected and analyzed retrospectively.Copyright © 2023 the Author(s). Published by Wolters Kluwer Health, Inc.
