骨科Ⅰ类切口手术部位感染流行的调查与控制

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。

Investigation and control on the epidemic of surgical site infection following clean wound operation in orthopedics patients

ObjectiveTo explore the investigation and control  method  for the  epidemic of surgical site infection(SSI)in a hospital. MethodsData of orthopedics patients receiving clean wound orthopedics operation were analyzed retrospectively, and effective measures were taken to control the epidemic of HAI. Results From June to August 2012, a total of 312 patients received clean wound  orthopedics operation,7 (2.24%) SSI cases occurred. SSI rates during the same period from 2009 to 2012 were significantly different(P<0.05), and was the highest in 2012. HAI management staff reviewed patients’ medical records,communicated  with staff in orthopedics department, and put forward  advice for SSI control; orthopedics department worked out and implemented detailed infection control measures. The subsequent surveillance showed that the prevalence of SSI in orthopedics ward decreased to 0.38%，infection outbreak  was effectively controlled. ConclusionHAI management department played an important role in the finding and control of HAI outbreak. Scientific analysis on monitored data and proper measures adopted by HAI management department and clinical department can effectively control HAI outbreak.
