骨科手术部位感染危险因素

Risk factors for surgical site infection in orthopaedic surgery

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。

Abstract:

ObjectiveTo explore risk factors for surgical site infection(SSI) in orthopaedic surgery, and propose the intervention measures.Methods1 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. ResultsOf 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, emergency operation, incision numbers, incision types, and duration of operation (P<0.05). ConclusionMultiple factors contribute to SSI in orthopaedic surgery. It is necessary to take comprehensive prevention measures to reduce the incidence of SSI.
