成都市某三级甲等医院不同切口类型、不同危险指数手术切口术后感染率研究

目的 通过对成都市某三级甲等医院开展手术切口目标性监测,了解不同手术切口类型、不同危险指数术后切口感染率,确定该院感染管理控制的重点干预方向.方法 利用电子信息化系统对该院纳入监测范围的手术科室进行数据收集,分析手术患者术后伤口感染情况.结果 1 331例患者手术部位切口术后感染率为0.60 ％,其中Ⅰ类切口感染率为0.31％,Ⅱ类切口感染率为0.69％,Ⅲ/Ⅳ类切口感染率为1.78％;危险指数评分0分者感染率为0.13％,1分者感染率为0.84％,2分及以上者感染率为1.74％,经Fisher确切概率法分析显示,不同类型切口、不同手术危险指数评分患者手术感染率比较,差异均有统计学意义(P＜0.05).结论 该院Ⅲ/Ⅳ切口类型和手术危险指数评分2分及以上患者术后感染率最高,应加强该类患者术后感染的控制干预,通过主动监测,有效降低切口术后感染率,提高医疗质量,确保患者安全.

Study on postoperative infection rates of patients with different types of incisions and different risk indexes of operation in a tertiary hospital in Chengdu City

Objective To investigate postoperative infection rates of patients with different types of incisions and different risk indexes of operation in a tertiary hospital in Chengdu City through carrying out targeted monitoring of surgical incision,in order to determine important interventions for infection control.Methods The data about operating rooms in the hospital monitored in this study was collected via the Donghua software electronic information system,and the situation of postoperative infection of incision wounds was analysed as well.Results Among the 1 331 cases of patients,the total infection rate of postoperative incisions was 0.60％.The type Ⅰ,type Ⅱ and type Ⅲl/Ⅳ incision infection rate was 0.31％,0.69％ and 1.78％,respectively.The infection rate of patients whose surgical risk score was 0,1 point and ≥2 points was 0.13％,0.84％ and 1.74 ％,respectively.By Fisher exact test,there were statistically significant differences in postoperative infection rates among patients with different types of surgical incision and those with different surgical risk index scores(P＜0.05).Conclusion The postoperative infection rates of patients with type Ⅲ/Ⅳ incision and those with surgical risk index score≥2 points are the highest.It is necessary to emphasize and strengthen the intervention on controlling postoperative infections,effectively reduce the postoperative infection rate through active monitoring,in order to improve the quality of medical hospital treatment and ensure patients'safety.
