目的:从统计经济学角度探讨手术部位感染的经济损失。方法:采用1:1配对方法对出院病历进行回顾性病例对照研究,比较手术部位感染病例103例(病例组)与同期类似未发生手术部位感染的病例(对照组)的住院费用,评价手术部位感染的经济损失。结果:病例组住院费用的中位数是48674元,对照组是25698元(P<0.001),病例组是对照组的1.89倍,手术部位感染直接额外费用10145元;病例组住院日的中位数是27d,对照组是15d(P<0.001),手术部位感染延长住院天数中位数是12.5d。结论:手术部位感染的直接经济损失较大,由于住院日延长所造成的间接经济损失也不能忽视。
Objective: To investigate the economic loss of surgical site infection from the perspective of statistical economics. Methods: A retrospective case-control study on discharge records was conducted by using a 1: 1 pairing method. The hospitalization costs of 103 cases (case group) and no case of infection of the same surgical site (control group) during the same period were compared. Economic loss of infection. Results: The median hospitalization cost was 48,674 yuan in the case group, 25,898 yuan in the control group (P <0.001), 1.89 times in the case group and 10,145 yuan in the direct operation site infection group. The median hospitalization day of the case group The number was 27d in the control group and 15d in the control group (P <0.001). The median length of hospital stay was 12.5d. Conclusion: The direct economic loss of surgical site infection is large, indirect economic losses caused by the extension of hospital stay can not be ignored.
