多元线性回归在妊娠、分娩和产褥期患者住院费用分析中的应用

MLR application in analysis of hospitalization costs of pregnancy,childbirth and puerperium patients

目的对影响妊娠、分娩和产褥期患者住院费用的因素进行探讨,为今后合理制定付费制度提供实证依据。方法采用统计描述、非参数统计、秩和检验和多元线性回归等方法,对12 788例妊娠、分娩和产褥期患者住院费用负担情况及影响因素进行探讨。结果结果显示患者平均住院费用7 779.96元,其中诊查费2 326.62元,诊查费和西药费之和超过住院总费用的50%。结论高龄产妇剖宫率高,平均住院费用也相应较高。转科、抢救、感染、并发症与合并症对住院费用有显著贡献。

Objective To explore the influencing factors of hospital costs of pregnancy,childbirth and puerperium patients,in order to provide empirical research for establishing reasonable payment system in the future. Methods Statistical description,nonparametric statistics,rank-sum test,multivariate linear regression（MLR） and so on were adopted to dicuss the hospitalization expense and influencing factors of 12 788 patients during pregnancy,childbirth and the puerperium. Results The results showed that the average hospital cost was 7 779.96 yuan,including the inspecting fee of 2 326.62 yuan,and the cost of inspecting and Western medicine accounted for more than 50% of the total hospitalization costs. Conclusion The cesarean delivery rate is high among the elderly parturient women,and the average hospitalization cost is also high. Transferring,rescue,infections,and complications all make significant contributions to the hospitalization costs.
