我国卫生服务个人总支出的PAF估计模型

Study on PAF Model for Estimation of Expenditure from Individual Payment for health care Service

了解某人群中医院住院服务个人总支出,对于评价卫生经费总投入及其构成比例具有重大意义。本文首次提出估算医院住院服务费用个人总支出的PAF模型。在校正人口结构的差异、不同年龄及不同病种住院率的差异、不同病种平均住院费用的差异之后估计总费用,所得结果更加符合实际情况。应用该模型及其有关系数,可分别估计全国的,分城市和农村的,大、中、小城市的及一、二、三、四类农村人群的医院住院服务费用个人总支出。

With data from the 1993 National Health Service Survey, this study developed a mathematical moael named PAF, for estimation of national expenditure from individual payment tphospital for the In-patients. It is based on age and disease specific rate of payment for eachservice and total population. The model bears the feature to adjust for the differences in population age structure. With the model and the corresponding parameters established, total expenditure from individual payment for the In-patient services can be estimated at rural and urban levels, as well as the National totals.
