目的调查我国医院手术部位感染(SSI)情况及相关危险因素,为我国SSI的防治提供理论依据。方法对全国部分省及直辖市共29所医院大肠手术、腹式子宫切除术、股骨颈修复术和血管手术4类手术进行前瞻性监测,分析SSI的危险因素。结果共纳入6 309例手术,SSI发病率为1.60%,其中大肠手术SSI发病率为4.47%(74/1 655)、腹式子宫切除术为1.03%(22/2 139)、股骨颈修复术为0.21%(5/2 372)、血管手术为0.00%(0/143)。各地区SSI发病率比较,差异有统计学意义(χ2=114.213,P<0.05)。最常见的术后SSI类型为表浅切口感染,其次为深部切口感染。引起SSI最常见的病原菌为大肠埃希菌、肠球菌属细菌、凝固酶阴性葡萄球菌、金黄色葡萄球菌和肺炎克雷伯菌。男性、手术持续时间长、NNIS评分高是发生SSI的独立危险因素。结论不同手术类型发生SSI风险不同,男性、手术持续时间长、NNIS评分高可增加术后SSI发病率。
Objective To investigate the situation of surgical site infection (SSI) and its related risk factors in hospitals in our country and provide a theoretical basis for the prevention and treatment of SSI in China. Methods Four kinds of operations including colorectal surgery, abdominal hysterectomy, femoral neck revision and vascular surgery in 29 hospitals in some provinces and municipalities of China were prospectively monitored, and the risk factors of SSI were analyzed. Results A total of 6 309 surgeries were enrolled. The incidence of SSI was 1.60%. The incidence of SSI in colorectal surgery was 4.47% (74/1 655), that of abdominal hysterectomy was 1.03% (22/2 139) Was 0.21% (5/2 372) and vascular surgery was 0.00% (0/143). The incidence of SSI in all regions, the difference was statistically significant (χ2 = 114.213, P <0.05). The most common type of postoperative SSI was superficial incisional infection, followed by deep incisional infection. The most common pathogens causing SSI are Escherichia coli, Enterococcus bacteria, coagulase-negative staphylococcus, Staphylococcus aureus and Klebsiella pneumoniae. Men, long duration of surgery, high NNIS score is an independent risk factor for the occurrence of SSI. Conclusion There are different SSI risks in different surgical types. Men, long duration of operation and high NNIS score can increase the incidence of postoperative SSI.
