脑梗塞医院感染经济损失的病例对照研究

目的 了解分析脑梗塞医院感染所造成的经济损失。方法 采用病例对照研究的方法,调查我院1997年1月～2001年3月脑梗塞医院感染的直接经济损失,共47对。结果 病例组的平均医疗费用比对照组增加了12 052.00元,两组差异有显著性（P<0.05）;医院感染费用的增加,主要是西药费、治疗费的增加,分别占整个费用的58.28％和18.03％;不同感染部位患者的医疗费用在病例组与对照组间差异均具显著性（P<0.01）;47例感染者中,平均住院天数比对照组高出25.74d,两组间差异有显著性（P〈0.01）。结论 脑梗塞发生医院感染使患者医疗费用、住院天数增加,从而影响医院病床周转率,降低医院收入,将医院感染的成本效益分析纳入医院感染管理工作中,对预防和控制医院感染具有重大意义。

The Economic Losses due to Nosocomial Infection in Patients with Cerebral Infarction: A Case-control Study

OBJECTIVE To evaluate and analyze the economic losses by nosocomial infection in patients with cerebral infarction. METHODS A case-control study was adopted in 47 pairs of inpatients from Jan 1997 to Mar 2001 in our hospital. RESULTS Total medical treatment charges were much more increasingly in case group (17 757. 7 yuan) than in control one (5 705. 73 yuan). There was a significant difference between two groups(P<0. 05). The main increases in economic losses due to nosocomial infection was the increases in medicine and therapeutic procedure charges. The econimic losses varied with infection foci. There was a significant difference between the economic losses of various infection foci (P<0. 01). In 47 cases the hospitalization days increased 25. 74% more than in control one. with a significant difference between two groups(P<0. 01). CONCLUSIONS Nosocomial infection would increase the hospitalization days and the economic losses for the patients, cut down the turnover rate of hospital bed and decrease the hospital income. So put the cost-benefit analysis of nosocomial infection into the hospital management is very important to prevent and control the nosocomial infection.
