目的了解手术部位感染(SSI)的特点,为SSI的预防与控制提供参考。方法采用医院感染实时监测系统对2015年1-12月手术出院患者进行SSI监测。结果 22 060例手术患者中,发生SSI 68例,发病率为0.31%;胸外科和神经外科SSI发病率较高,分别为2.42%和2.05%;手术风险分级0-3的患者SSI发病率分别为0.12%、0.69%、1.74%和2.94%,差异有统计学意义(P<0.001);SSI类型中器官(或腔隙)感染占52.94%;手术部位病原学送检率为76.47%,阳性率为75.93%,共检出病原菌43株,其中革兰阴性菌占58.14%。结论器官(或腔隙)感染是SSI主要类型,革兰阴性菌是SSI主要病原体,应重点关注胸外科和神经外科以及手术风险分级高的患者的SSI防控工作。
Objective To understand the characteristics of surgical site infection (SSI), provide a reference for the prevention and control of SSI. Methods SSI monitoring was performed on patients discharged from January to December 2015 with the real-time monitoring system of nosocomial infection. Results Among 22 060 surgical patients, SSI occurred in 68 cases with a prevalence of 0.31%. The incidence of SSI in thoracic and neurosurgical patients was 2.42% and 2.05% respectively. The incidence of SSI in patients with surgical risk grade 0-3 were respectively (0.12%, 0.69%, 1.74% and 2.94%, respectively), the difference was statistically significant (P <0.001). The infection rate of organs (or lacunar) in SSI type was 52.94%. The etiological rate in operation site was 76.47% The rate of 75.93%, a total of 43 pathogenic bacteria were detected, of which Gram-negative bacteria accounted for 58.14%. Conclusions Organ (or lacunar) infection is the major type of SSI. Gram-negative bacteria are the major pathogens of SSI. SSI prevention and control should be focused on thoracic surgery and neurosurgery and patients with high surgical risk classification.
