根本原因分析法在控制胆道外科手术部位感染中的应用

Root cause analysis for preventing surgical site infection of biliary tract surgeries

目的 分析胆道外科手术部位感染相关危险因素,采取相应干预措施降低手术部位感染率.方法 采用根本原因分析法对胆道手术部位感染相关危险因素进行分析,并采取相应措施,对比处理前后的干预效果.结果 调查阶段共进行胆道外科手术275例,发生手术部位感染56例,感染率为20.36％.根本原因分析法显示BMI、糖尿病、胆道感染、手术时间、切口类型等与胆道外科手术部位感染密切相关.干预阶段共进行胆道外科手术244例,发生手术部位感染7例,感染率2.87％.结论 应用根本原因分析法干预可有效控制胆道外科手术部位感染.

Objective To investigate the risk factors of surgical site infection after hiliary tract surgeries and to take effective measures to prevent and control it. Methods Root cause analysis was employed to investigate the risk factors of surgical site infection. The effect of relative measures was assessed after the intervention. Results During the investigation period, 275 patients underwent biliary tract surgeries; among which, 56 patients were diagnosed with surgical site infection, with a surgical site infection rate of 20.36%. The root cause analysis indicated that body mess index, biliary tract infection, diabetes, operating time, incision styles, and incision cleaning significantly correlated with SSI incidences （P〈0.05）. During the period of intervention by corresponding measures, 244 patients underwent biliary tract surgery, and 7 （2.87%） got surgical site infection. Conclusion Root cause analysis can effectively reduce the surgical site infection of biliary tract surgeries.
