骨科手术部位感染危险因素

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1 082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1 082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。

Risk factors for surgical site infection in orthopaedic surgery

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.
