目的 了解肺部感染、泌尿道感染、深部术后伤口感染和颅内感染 4种重要类型医院感染所造成的直接经济损失。方法 采用 1∶1配比病例对照研究方法 ,调查 95对患者的医疗费用 ,计算医院感染的直接经济损失。结果 病例组的平均医疗费用为 38741元 ,对照组为 18376元 ,平均每例感染病人多支出医疗费用 2 0 36 5元 (P <0 .0 0 0 1)。医疗费用的增加以西药费为主 ,占总增加费用的 6 2 .0 7% ;其次是治疗费、输血费和化验费 ,分别占总增加费用的 10 .32 %、7.40 %和 5 .72 %。医院感染的经济损失因科室不同而异 ,肿瘤血液科最高 ,平均每例增加 34 944元。肺部感染、泌尿道感染、深部术后伤口感染和颅内感染患者的医疗费用平均每例分别增加 31940元、7436元、17332元和 1734 9元。 95例感染患者的平均住院天数为 5 0 .5 7d ,比对照组的 2 5 .2 2d高出 2 5 .5 3d(P <0 .0 0 0 1)。结论 医院感染严重增加了医疗费用支出 ,降低了病床周转率 ;认真做好医院感染监控工作可获得巨大经济效益和社会效益
Objective To understand the direct economic loss caused by four important types of nosocomial infections such as pulmonary infection, urinary tract infection, deep postoperative wound infection and intracranial infection. Methods A 1: 1 matched case-control study was conducted to investigate the medical costs of 95 pairs of patients and calculate the direct economic loss of nosocomial infections. Results The average medical cost of the case group was 38,741 yuan and that of the control group was 18,376 yuan, with an average of 2,036 5 yuan (P <0.001) of the medical expenses for each infected patient. The increase in medical expenses was dominated by western medicine fees, accounting for 62.07% of the total increase; followed by treatment, blood transfusion and laboratory tests, accounting for 10.32%, 7.40% and 5.72 of the total increase respectively %. The economic loss of nosocomial infections varies from department to department, with the highest degree of oncology and hematology, with an average increase of 34,944 yuan per case. In the case of pulmonary infection, urinary tract infection, deep postoperative wound infection and intracranial infection, the average medical expenses increased by 31,940 yuan, 7436 yuan, 17,332 yuan and 1,734,9 yuan respectively. The mean length of hospital stay in 95 infected patients was 57.5 days, which was 25.5 days more than the 25.22 days of the control group (P <0.0001). Conclusion The hospital infection seriously increased the medical expenses and reduced the turnover rate of the hospital bed. Serious economic and social benefits can be obtained when seriously monitoring the hospital infection
