摘　　要：目的　应用病例组合指数在DEA模型中估计医院的相对服务效率。方法　首先应用信息理论计算病例组合指数 ,再将其与出院人数的乘积 (产出量 )作为产出指标 ,在DEA模型中估计医院的相对服务效率。结果　应用病例组合指数所得到的效率值更加合理准确 ;大多数医院处于规模收益递减、低效率的运行状态。结论　此方法考虑到了疾病严重程度对于医院服务效率的影响 ,使估计的效率值更加准确。Objective Estimating hospital efficiency by the data envelopment analysis with case mix index.Methods First, we compute case mix index with information theory; second we estimating hospital efficiency by the Data Envelopment Analysis in which the product of case mix index and the number of inpatients is the output variables.Results The efficiency variables are more reasonable than others, and most of the hospitals are descending of returns to scale and low efficiency.Conclusion This research the first time adopts case mix index in DEA to evaluate the hospital efficiency considering the infections of disease complicated degree, so it makes the result more accurate and more reliable.
