目的研究住院天数与例均费用的关系,为减轻患者医疗负担,为医院管理提供理论支持,为医疗改革提供依据。方法从数据库中提取2013年-2015年出院患者数据,探索住院天数相同患者的例均费用与住院天数的关系;使用R语言对2015年的数据进行一元回归和多项式回归。结果 3年的数据变化趋势基本一致,住院天数小于25天的患者的例均费用基本呈简单线性关系;住院天数大于25的患者的例均费用有明显的先下降后上升的趋势,得到例均费用Y与住院天数X的分段回归方程:当1≤X≤25时,Y=1558.15X-1243.09;当25≤X≤31时,Y=217.4-17,095.2X2+445,828.8X-3,819,533.2。结论住院天数对费用的影响明显,控制住院天数对降低患者的医疗费用,提高医院资源利用效率有重要的意义。
Objective To study the relationship between the days of hospitalization and the average cost per patient in order to provide theoretical support for hospital management and to provide the basis for the medical reform in order to reduce the medical burden on patients. Methods The data of discharged patients from 2013 to 2015 were extracted from the database to explore the relationship between the average cost of patients with the same number of days of hospitalization and the number of days of hospitalization. The R language was used to perform a one-way regression and a polynomial regression on 2015 data. Results The trend of 3-year data was basically the same. The average cost of patients with less than 25 days of hospitalization was basically simple linear. The average cost of patients with more than 25 days of hospitalization obviously decreased first and then increased. Fractional regression equation of cost Y and hospitalization days X: Y = 1558.15X-1243.09 when 1≤X≤25; Y = 217.4-17,095.2X2 + 445,828.8X-3,819,533.2 when 25≤X≤31. Conclusion The impact of hospitalization days on expenses is obvious. Controlling the days of hospitalization is of great significance to reduce the medical expenses of patients and improve the utilization efficiency of hospital resources.
