基于logistic模型的自我医疗行为分析

An Analysis on Self-medication Based on Logistic Lodel

目的:探明自我医疗的影响因素,为政府制定减少自我医疗使用的政策提供依据;方法:基于第五次卫生服务调查数据,采用Andersen对卫生服务利用的分析框架,对自我医疗的影响因素进行logit模型分析。结果:医疗保险类型、距离最近医疗点距离、发病种类对自我医疗的影响具有显著性。边际和弹性分析显示,若有1%的城镇居民医疗保险参加者转换为城镇职工医疗保险,可使自我医疗概率降低0.157%,距医疗点距离由≥5公里缩短为不足1公里的弹性系数大于1;结论:政府可在提高医疗保障报销比例、加大农村地区医疗资源供给方面努力,降低自我医疗比例。

Objective To explore the determinants of self-medication, and provide evidence for government policy making. Methods Based on the data of Fifth National Health Survey, Andersen＇s behavioral model of health services use is applied to the logit model for self medication. Results Health insurance, distance to the nearest clinic and the urgency of the disease are statistically significant in the logit model. Also, 1% conversion of Medical Insurance for Urban Residents （MUR） to Medical Insurance for Urban Workers （MUW） could decrease the probability of self medication by 0. 157%, the elasticity coefficient of converting the nearest clinic with more than 5 kilometers away to a more convenient one with less than 1 kilometers is 1. 029. Conclusions Increasing the proportion of insurance reimbursement, offering more medical resources in rural areas could decrease the probability of self medication.
