基于灰色关联法与结构变动度的肺癌患者住院费用分析

Analysis of Hospitalization Expenses of Lung Cancer Patients Based on Gray Correlation Method and Structural Variation Degree

目的探究影响肺癌患者住院费用构成及其变动趋势,为优化和调整费用结构提供参考。方法收集2015年1月1日-2019年12月31日安徽省某综合医院8460例肺癌患者住院费用构成资料,采用灰色关联法和结构变动度法,对住院次均费用的各构成项目与住院次均费用的关联程度及结构变动情况进行统计分析。结果肺癌患者年次均住院费用处于增长趋势,年均增长速度为3.04%,次均费用构成平均占比前3位的分别是药品费28.16%,耗材费21.58%,诊断费21.22%,次均住院费用中关联度排前3位的是药品费、耗材费、诊断费;住院费用总体结构变动度为36.27%,医疗服务费、治疗费和药品费呈负向变动,药品费结构贡献率最大(43.38%),其次为其他费(19.21%)、耗材费(19.11%)。结论肺癌患者经济负担得到缓解,药品费控制效果显著,诊断类与耗材类费用是控制住院费用的重点,应合理提高技术劳务性项目费用比例,进一步优化住院费用结构。

Objectives This study aims to explore the influence of lung cancer patients'inpatient cost composition and the trend of change,so as to provide a reference for optimization and adjustment of cost structure.Methods The inpatient cost composition data of 8460 patients with lung cancer in a general hospital in Anhui Province from January 1,2015 to December 31,2019 were collected.The gray correlation method and structural variation degree method were used to analyze the correlation degree and structural change of each component item of average inpatient cost and average inpatient cost.Results The average annual inpatient cost of lung cancer patients showed an increasing trend,with an average annual growth rate of 3.04%.The top three components of average inpatient cost were drug cost 28.16%,consumables cost 21.58%and diagnosis cost 21.22%,respectively.The top three correlations among average inpatient costs were drug cost,consumables cost,and diagnosis cost.The overall structure variation degree of hospitalization expenses was 36.27%.The medical service fee,treatment fee,and drug cost changed negatively.The contribution rate of drug cost structure was the largest(43.38%),followed by other expenses(19.21%)and consumables(19.11%).Conclusions The economic burden of lung cancer patients has been alleviated.The drug cost control effect is remarkable.The diagnosis and consumable costs are the key to controlling the hospitalization cost.The cost ratio of technical labor items should be increased reasonably,and the structure of hospitalization expenses should be further optimized.
