目的探讨某院手术部位感染(SSI)暴发流行的调查与控制方法。方法对骨科Ⅰ类切口手术患者资料进行回顾性调查分析,并采取干预措施,控制医院感染的暴发流行。结果 2012年6—8月该院骨科Ⅰ类切口手术患者312例,发生SSI 7例,SSI发病率为2.24%。2009—2012年同期Ⅰ类切口SSI发病率比较,差异有统计学意义(P<0.05),其中2012年SSI发病率最高。通过病例调查,医院感染管理科分析感染可能原因,并与骨科沟通,提出7项整改要求;骨科制定18项SSI防控细则并切实执行。后续追踪结果显示,2012年9—11月,该科SSI发病率为0.38%,回落至正常水平,此次SSI流行得到有效控制。结论医院感染管理部门对及时发现医院感染暴发流行具有重要意义;和临床科室对监测数据进行科学分析,针对性地采取控制措施,能有效控制医院感染暴发流行。
Objective To investigate the prevalence of surgical site infection (SSI) in a hospital and its control measures. Methods The data of patients undergoing type Ⅰ incision surgery were retrospectively analyzed and the interventions were taken to control the outbreak of nosocomial infection. Results From June to August in 2012, 312 patients underwent type Ⅰ incision surgery in our hospital. There were 7 SSI cases and the incidence of SSI was 2.24%. The incidence of SSI in type Ⅰ incision in the same period of 2009-2012 was significantly different (P <0.05), of which the incidence of SSI in 2012 was the highest. Through the case investigation, the Hospital Infection Management Division analyzed the possible causes of infection and communicated with the orthopedic department and proposed seven rectification requirements; and the department of orthopedics formulated 18 SSI prevention and control rules and implemented it practically. Follow-up results showed that from September to November 2012, the incidence of SSI in this family was 0.38%, down to normal levels, and the epidemic of SSI was effectively controlled. Conclusions The hospital infection management department is of great significance in discovering the outbreak of nosocomial infection in time. Scientific analysis of monitoring data in clinical departments and targeted control measures can effectively control the outbreak of nosocomial infections.
