骨科手术部位感染危险因素

摘要

目的：探讨骨科手术部位感染（SSI）的危险因素，以针对危险因素提出干预措施。方法采用目标性监测方法，对2012年1月—2013年12月某院骨科1082例手术患者进行监测，由医院感染管理专职人员通过查阅病历资料、现场查看切口及出院后电话随访等方式了解SSI 情况。结果共监测骨科手术患者1082例，发生SSI 8例，SSI率为0．74％。单因素分析结果显示，SSI与年龄、合并糖尿病、急诊手术、切口个数、切口类型、手术时间、植入物7项因素有关（均P＜0．05）；logistic回归分析结果显示，年龄、合并糖尿病、急诊手术、切口个数、切口类型、手术时间是SSI的独立危险因素（均P＜0．05）。结论 SSI的发生是多种因素作用的结果，必须采取综合性预防措施才能有效降低SSI的发生率。%Objective To explore risk factors for surgical site infection(SSI)in orthopaedic surgery,and propose the intervention measures. Methods 1 082 patients who received orthopaedic surgery in a hospital from January 2012 to December 2013 were monitored,SSI were surveyed by healthcare-associated infection control professionals based on medical records reviewing,on-site examination of surgical incision and post-discharged following up call. Results Of 1 082 patients,8(0.74% )developed SSI. Univariate analysis revealed that SSI were related to patients’age, associated diabetes mellitus,emergency operation,incision numbers,types of incisions,duration of operation,and implant (P<0.05);Logistic regression analysis revealed that independent risk factors for SSI were age,diabetes mellitus,emer-gency operation,incision numbers,incision types,and duration of operation (P<0.05). Conclusion Multiple factors contribute to SSI in orthopaedic surgery. It is necessary to take comprehensive prevention measures to reduce the in-cidence of SSI.
