4种类型医院感染的经济损失病例对照研究 FREE

目的从卫生经济学角度，分析医院上呼吸道、下呼吸道、泌尿道、手术部位感染所造成的经济损失。方法采用1∶1配对的方法，调查100对患者［发生上述医院感染的患者（病例组）与同期类似住院未发生医院感染的患者（对照组）］的卫生资源消耗并进行比较，对医院感染进行经济学评价。结果病例组住院总费用中位数每例为22 379.01元，对照组为7 611.52元，病例组显著高于对照组（Z=-6.72，P=0.00）；医院感染经济损失因感染部位的不同而异，下呼吸道感染经济损失最大，为21 701.03元，其次为泌尿道感染6 374.52元、手术部位感染5 849.04元、上呼吸道感染3 598.00元；患者住院费用的增加主要是药费、检验费、材料费、治疗费、处置费；病例组中位数每例患者住院时间为24.51 d，对照组为11.00 d，两组间差异有统计学意义（Z=-7.84，P＝0.00）。结论医院感染造成的经济损失较大，经济损失因感染部位的不同而异；同时，由于发生医院感染而延长了患者的住院时间。

Case control study on economic loss of four types of nosocomial infection FREE

Objective To evaluate the economic loss caused by upper respiratory tract infection, lower respiratory tract infection, urinary tract infection and surgical wound infection from the point of health economy. Methods Based on 1 ： 1 matching method, health resource expense of 100 patients patients with nosocomial infection （NI, infection group） and patients without NI （control group）] were compared, and economic evaluation were carried out. Results The median of total hospitalization expenses of each case were 22 379. 01 and 7 611.52 yuan in infection and control group respectively, infection group was significantly higher than control group （Z = - 6. 72, P = 0. 00）. The economic loss varied from infection sites, the highest loss was caused by lower respiratory tract infection, which were 21 701.03 yuan,the following were urinary tract infection, surgical wound infection and upper respiratory tract infection, which were 6 374. 52, 5 849. 04 and 3 598. 00 yuan respectively; The main increased expenses of hospitalization were medicine cost, laboratory test cost, material cost, therapy costs and disposable fee; The median of hospitalization days of each patient in infection group and control group were 24. 51 and 11.00 days respectively, there was significant difference between the two（Z = - 7. B4, P = 0. 00）. Conclusion The economic loss are large caused by NI, the loss varied from infection sites, hospitalization days were prolonged by NI.
