普通外科手术部位感染的目标性监测研究

Research on target monitoring of surgical site infection in general surgery

目的 了解某医院普通外科手术部位感染现况及其影响因素,为采取有效的干预措施提供依据。方法 2012年11月—2014年12月对某医院普通外科开展手术部位感染（SSI）的目标性监测研究。结果 1021例手术患者发生SSI28例,感染率为2.74%。其中以手术切口部位的感染率最高,达8.75%。SSI专率为0.76%-6.52%,调整后感染专率为1.02%-7.06%。经单因素及多因素logistic回归分析：切口等级、手术持续时间、危险指数为SSI的危险因素（P〈0.05）。感染部位分泌物培养出的病原菌以革兰阴性菌为主。结论 切口污染越严重、手术持续时间越长,手术危险指数越高,SSI发生率也越高。

[Objective]To investigate the incidence and risk factors of surgical site infection（SSI） in general surgery of a hospital, provide the reference for taking effective measures to reduce incidence of SSI. [Methods]From November 2012 to December 2014, a target monitoring method was used to study the incidence and risk factors of SSI in general surgery of a hospital. [Results]28 patients had surgical site infections among 1 021 patients undergoing general surgery and the infection rate was 2.74%. The infection rate in incision site was highest, which reached 8.75%. The doctors＇ special SSI rates were between 0.76% and 6.52%, and the adjusted special SSI rates were between 1.02% and 7.06%. The single-factor and multiple logistic regression analysis showed that the incision grade, surgical duration, and risk index were the risk factors of SSI （P〈0.05）. By the secretion culture, Gram-negative bacteria were the most common pathogens in the infection site. [Conclusion]The patients with more severely contaminated incision, longer surgical duration and higher surgical risk index are more prone to occur the SSI.
