A continuous record of postoperative surgical infections was carried out by electronic data processing (EDP) of 4340 orthopaedic and general operations. The overall infection rate was 6.3%, ranging from 2.3% (clean wounds) to 27.1% (dirty wounds). The corresponding deep infection rates were 1.6%, 0.4% and 4.6%. Employing a multiple logistic regression analysis, 10 risk factors were evaluated. Factors found to be significant were: wound contamination, department, duration of operation, date of operation and age, and in addition for the department of general surgery: surgeon, planning of operation, length of preoperative stay and anatomic groups. A statistical model for identification of risk patients is described. Postoperative stay was on average 20.5 days longer in infected patients. We find that EDP-recording may result in an annual cost reduction of at least 175,000 pounds for our hospital.
通过对4340例骨科手术和普通外科手术进行电子数据处理，对术后手术感染情况进行了连续记录。总体感染率为6.3%，范围从2.3%（清洁伤口）到27.1%（污染伤口）。相应的深部感染率分别为1.6%、0.4%和4.6%。采用多元逻辑回归分析，评估了10个风险因素。发现具有显著意义的因素有：伤口污染、科室、手术时长、手术日期和年龄，此外对于普通外科还包括：外科医生、手术规划、术前住院时长和解剖学分组。描述了一种用于识别高危患者的统计模型。感染患者的术后住院时间平均延长20.5天。我们发现，电子数据处理记录可为我院每年至少节省17.5万英镑的成本。
