某医院外科手术部位感染目标性监测与分析

Target surveillance and analysis of surgical site infection in a hospital

目的探讨某医院外科手术部位感染的发病率及危险因素。方法对2016年1月-12月外科手术部位感染的状况进行目标性监测,采用病例对照研究方法进行危险因素分析。结果监测1 076名外科手术患者,发生手术部位感染42例,手术部位感染率为3.90%,感染病原菌以革兰阴性杆菌为主。logistic回归分析结果显示,外科手术部位感染危险因素为年龄>60岁、手术持续时间3 h以上、术前抗菌药物联合使用及2级、4级ASA评分。结论应根据外科手术部位感染的相关危险因素进行综合管理。

Objective To explore the incidence rate and risk factors of surgical site infections in a hospital. Methods Case-control study was used in target surveillance of surgical site infections from January to December 2016. Results A total of 1 076 surgical patients were monitored. 42 of them had surgical site infection. The surgical site infection rate was3. 90%. The main pathogenic bacteria were Gram negative bacilli. Logistic regression analysis showed that the main risk factors of surgical site infection were： age 60 years old,duration of surgery more than 3 hours,combined use of antibiotics before surgery and ASA score 2 and 4. Conclusions Comprehensive management should be carried out according to the related risk factors of surgical site infection.
