103例手术部位感染经济损失评价

Evaluation of Economic Losses for 103 Surgical Site Infections

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 influence of surgical site infection on economic loss from the perspective of statistics and economics. Methods Using 1：1 matching methods for retrospective case-control study of hospital patient records to evaluate the economic losses by comparing the cost of 103 cases of surgical site infection（case group） wilh those without infection （control group）. Results The median of the hospitalization cost was 48674 Yuan and 25698 Yuan （P〈0.001） for case group and control group respectively; It is 1.89 times in case group than in control group, which means the extra cost for case group is 10145 Yuan. The median length of stay in hospital was 27 days and 15 days （P〈0.001） for case group and control group respectively. The median of extending hospitalization day was 12.5 days. Conclusion The direct economic loss caused by surgical wound infection is significant. Besides, the indirect economic loss caused by extended hospitalization days cannot be ignored.
