| 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20365元(P<0.0001)。医疗费用的增加以西药费为主，占总增加费用的62.07%;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34944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17349元。95例感染患者的平均住院天数为50.57d，比对照组的25.22d高出25.53d(P<0.0001)。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。 |

| ObjectiveTo evaluate the direct economic costs of four major kinds of nosocomial infections such as nosocomial pneumonia, urinary tract infection, deep surgical wound infection and intracranial infection.Methods A matched case -control study was conducted among 95 pairs of hospitalized patients to investigate the direct economic costs of nosocomialinfections. Results The average medical cost for patients in the case group was 38 741 RMB Yuan, 20 365 Yuan more than that in the control group patients( P<0. 000 1). The largest part of extra costs was found in drug expenses, taking up 62. 07%, while other extra costs such as non-drug therapies, blood transmission and laboratoryexaminations, accounted for 10. 32%, 7. 40% and 5. 72% respectively. Extra economic burden caused by nosocomial infections varied in different degrees with different departments, with the heaviest found in the department of tumourology and hematology at an average extra cost of 34 944 Yuan.The average extra chargesin case group caused by nosocomial pneumonia, urinary tract infection, deep surgical wound infectionand intracranial infection were 31 940 Yuan, 7 436 Yuan, 17 332 Yuan and 17 349 Yuan respectively. The average length of hospital stay was 50. 57 days in case group and 25. 22 days in control group, showing a 25. 53 extra days( P <0. 000 1)of hospitalization due to nosocomial infections.Conclusion Nosocomial infections had significantly added to the economic burden of managing the underlying diseases, led toprolonged hospitalization of the patients and lowered the turnover rate of hospital bed.There is a need to call for better infection control program, which would bring tremendous social and economic profits. |
