Identification of Predictive Factors for Surgical Site Infections in Gastrointestinal Surgeries: A Retrospective Cross-Sectional Study in a Resource-Limited Setting

Over seven years from June 2015 to June 2022, patients who underwent GI surgery and developed SSI were retrospectively matched with an unaffected case-control cohort of patients. Standardized techniques for wound culture, laboratory evaluation of bacterial isolates, and antibiotic susceptibility tests were employed. Logistic regression analysis was utilized to investigate the predictive factors associated with 30-day postoperative SSI.本研究纳入2015年6月至2022年6月共7年时段内，接受胃肠道（GI）手术后发生手术部位感染（Surgical Site Infection, SSI）的患者，并将其与未发生感染的病例对照队列患者进行回顾性匹配。本研究采用标准化的伤口培养、细菌分离株实验室检测及抗生素敏感性试验技术，通过logistic回归分析探究与术后30天手术部位感染相关的预测因素。
