肺炎儿童住院费用影响因素的通径分析

目的：分析肺炎儿童住院费用的影响因素，为其费用控制提供相关依据。方法对重庆市某院2011年927例肺炎儿童的住院费用及相关因素进行通径分析。结果住院费用影响因素多因素回归分析结果显示：药费比例、住院时间、付款方式、入院情况、治疗结果和年龄（R2＝0．867，F＝597．552，P＜0．01）为其影响因素。药费比例、入院情况、治疗结果还通过影响住院时间对住院费用产生间接影响（R2＝0．506，F＝330．336，P＜0．01）。通径分析结果显示，各因素总通径系数由大到小依次为：药费比例、住院时间、治疗结果、付款方式、入院情况、年龄。结论降低药费比例、减少住院时间、加强医保患者费用监管力度是控制肺炎儿童住院费用的有效措施。

Path analysis of children pneumonia hospitalization expenses and its influencing factors

Objective To investigate the influencing factors of children pneumonia hospitalization expense and provide refer‐ence for its expense control .Methods Path analysis was performed on the hospitalization expense and its influencing factors based on 927 pneumonia children in a hospital in Chongqing in 2011 .Results Multivariate regression analyasis showed that the influen‐cing factors of children pneumonia hospitalization expense were proportion of drug expense ,length of hospital stay ,type of pay‐ment ,admission condition ,therapeutic outcome and age .The coefficient of determination (R2 =0 .867 ,F=597 .552 ,P<0 .01) .Be‐sides ,proportion of drugs ,admission condition and therapeutic outcome had indirect effects by influencing hospital stay .The coeffi‐cient of determination (R2 =0 .506 F=330 .336 ,P<0 .01) .According to the total coefficient of path analysis ,the factors of influen‐cing hospitalization expense were listed in descending order as follows :proportion of drug expense ,length of hospital stay ,therapeu‐tic outcome ,type of payment ,admission condition and age .Conclusion Reducing drug proportion ,length of hospital stay ,and strengthening supervision on medicare patients′ expense are effective measurements to control children pneumonia hospitalization ex penses .
