医保患者住院费用分布与影响因素分析

Analysis of the Expenditure Distribution of Medical Insurant Inpatients and its Influencing Factors

目的探讨医保患者住院费用的分布特点和影响因素。方法用线性回归模型分析影响医保患者住院费用的因素;用非参数秩和检验方法分析较高水平住院费用的影响因素。结果影响住院费用的显著因素有住院天数、是否手术和性别;影响较高水平住院费用的显著因素是住院天数、是否手术和年龄。结论较高水平住院费用发生频率小,占总费用比例却达到69%。所以,较高水平住院费用是控制住院费用的重点,而控制住院费用的增长要从影响较高水平住院费用的显著因素入手。

Objective To explore the characteristics of the expenditure distribution of medical insurant inpatients and its influencing factors. Methods Linear regression analysis was be used to study the influencing factors of inpatient＇s costs. Then the rank sum test was be used to study the influencing factors of high level inpatient＇s cost. Results The length of stay, operation and gender were significant factors affecting high level expenditure. The length of stay, operation and age were significant factors affecting high level expenditure. Conclusion High level expenditure was not frequent, but its percentage reached 69% in the total of the expenditure. So these costs are the key to control the increasing cost of inpatients.
