摘要
目的研究疾病诊断相关分组预定额付费制(DRG-PPS)模式下病例年龄因素对平均住院费用的影响。方法选取北京市某三甲医院, 出院日期在2019年1月1日至12月31日的52 987例病例, 根据患者年龄将其分入三个年龄组, 即老年组、中年组、青年组, 首先三组数据按照DRG分组后进行单因素方差分析, 来判断同一DRG病组, 不同年龄组之间的费用差异, 其次三组数据进行相关样本非参数检验和线性回归, 来判断年龄因素对不同DRG组费用的影响。结果对相同DRG组的三个年龄组病例数据进行单因素方差分析, 除CB39-晶体手术DRG病组外, 其余各个DRG病组均P<0.05;对不同DRG组的三个年龄组病例数据进行相关样本非参数检验均P<0.05;对三个年龄组病例数据使用线性回归分析, P<0.05, 标化后的影响系数为0.173, 年龄与住院费用呈正相关。结论年龄影响平均住院费用, DRG-PPS模式实施后, 应根据年龄因素对DRG病组付费标准进行适当标化。
Objective To study the influence of patients'ages on average medical expenses under the diagnosis related group and prospective paymeni system(DRG-PPS)model.Methods Medical records of 52987 selected patients at a third-tier general hospital in Beijing were collected from January 1 to December 31.2019,and were then divided into three age groups based on age,the elderly group,lhe middle-aged group and the young group,and one-way ANOVA was used to determine differences in medical expenses between the same DRG group and different age groups.Related-sample nonparametric tests and linear regression were carried out for the three age groups to estimate the influence of the age factor on the medical expenses of different DRG groups.Results First.the data of the three age groups in the same DRG group were analyzed by one-way ANOVA.The P values of the DRG groups were less than 0.05,except for the cb39 crystal surgery DRG group;Then,the data of the three age groups in different DRG groups were analyzed with the nonparametric test(P=0.021),less (than 0.05);Finally,linear regression analysis was also used to analyze the case data of the three age groups.The p value was less than 0.05,and the standardized influence coefficient was 0.173,suggest!ng age was positively correlated with hospitalization expenses.Conclusions Age affects average hospitalization expenses.After the implementation of the DRG-PPS model w the payment of DRG patients should be standardized with the inclusion of the age factor.
