基于支持向量机的单病种医疗费用控制研究

Support Vector Machine Based Analysis of Factors Influencing Medical Expenses in Single Disease

目的:通过对医疗费用的主要影响因素进行分析,探寻合理控制医疗费用的有效方法。方法:以2008年广东省6地市7所不同等级医院的甲肝病人的医疗费用资料为样本,采用支持向量机模型对医疗费用进行统计学分析。结果:西药费用在医疗费用构成中所占比例最大。住院天数、医院等级、地区差异、出院情况、性别、支付方式、疾病类型是影响医疗费用的主要因素。结论:要控制医疗费用的快速增长,必须根据医疗费用的影响因素,制定合理的单病种限额付费制度。

Objective： To find effective method control medical expenses by analyzing the main factors influencing medical expenses. Methods： Data on medical expenses in seven hospitals of six cities in Gaangdong were taken as samples, A statistical analysis was conducted on the medical expenses by support vector machine model. Results： West medicine expenses are the largest proportion of medical expenses. Major factors affecting medical expenses are days of hospitalization, hospital level, regional differences, post-hospitalization conditions, sex, payment model, disease entities. Conclusion： In ordre to control the rapid increase of medical expenses, reasonable single disease payment policy must be made according to the major factors affecting medical expenses.
