摘　　要：通过分析结直肠手术后手术部位感染（SSI）发生的相关因素，为医院感染防控工作提供依据。选择2012年11月1日～2014年10月31日在某医院接受结直肠手术的548例患者作为研究对象。抽取365例研究样本经单因素筛选后进行多因素Logistic回归分析，找出相关影响因素；其余183例作为验证样本对模型的准确性进行验证。经多因素Logistic回归分析最终筛选出体质量指数、术前住院日、手术持续时间、抗菌药物使用不合理4个变量为结直肠手术后SSI发生的影响因素；经验证模型准确率为83．7％。因此得出结论：体质量指数、术前住院日、手术持续时间、抗菌药物使用不合理是结直肠手术后SSI发生的危险因素。To investigate the risk factors in the pathogenesis of surgical site infection （SSI） after colorectal surgery, thereby providing effective evidence for the prevention and controlling SSI. 548 patients who underwent colorectal operations from Nov 1st, 2012 to Oct 31st, 2014 were enrolled from a certain third-grade class A hospital. Of all patients, 365 were selected as investigation samples, while the other 183 as verification samples. For investigation samples, followed single- factor test, multivariate logistic regression were performed to screen the risk factors. After single-factor test followed by multivariate logistic regression, results showed that the risk factors are mass index, preoperative hospital stay, operation duration and non-rational use of antibacterial agents. Verification samples introduced in the model identified that the accuracy of this model is 83. 7%. Therefore, mass index, preoperative hospital stay, operation duration and non-rational use of antibacterial agents are potentially modifiable risk factors for predicting SSI in colorectal operation.
