【摘要】 目的 分析基于多元身份认证的“儿童一码就医”医保家庭共济服务模式对儿童门诊服务利用和医疗费用的影响，为相关创新服务模式的推广提供参考。方法 以内分泌科患者为研究对象，通过医院信息系统收集干预前1年至干预后1年内患者在内分泌科的全部门诊就诊数据，采用倾向得分匹配法和双重差分法进行分析。患者被分为3组，分别是参加基本医疗保险并加入医保家庭共济的干预组、仅参加基本医疗保险的对照组1、未参加基本医疗保险的对照组2。结果 加入医保家庭共济后，儿童患者年门诊就诊次数平均增加1.094次，门诊医疗费用增加32.8%，相较于自费患者分别平均增加1.815次和51.0%。儿童患者春季门诊就诊次数和医疗费用无明显变化，夏季门诊医疗费用降低，秋、冬季门诊就诊次数和门诊医疗费用均明显上升。结论 基于多元身份认证的“儿童一码就医”医保家庭共济服务模式有效增加了儿童患者门诊就诊次数和医疗费用，提升了慢性病患者的就医黏性和依从性。更多还原

【Abstract】 Objective To analyze the impact of the “One-Code for Children’s Medical Care” family mutual-aid medical insurance system, based on multiple identity authentication on children’s outpatient service utilization and healthcare costs, providing references for the promotion of similar innovative service models. Methods Endocrinology patients were selected as the study subjects. All their outpatient visit data, from one year before intervention to one year after the intervention, were collected through the hospital’s information system. A combination of propensity score matching(PSM) and difference-in-differences(DID) analysis was applied. Patients were divided into three groups: an intervention group that participated in basic medical insurance and joined the family mutual-aid system, and Control Group 1, who only participated in basic medical insurance, and Control Group 2, who did not participate in basic medical insurance. Results After joining the family mutual-aid system, pediatric patients experienced an average increase of 1.094 outpatient visits per year, and a 32.8% increase in outpatient costs. Compared with self-paying patients, the increases were 1.815 visits and 51.0%, respectively. Furthermore, a seasonal analysis indicated no significant changes in outpatient visits and costs in spring. However, costs decreased in summer, while both visit frequency and costs significantly increased in autumn and winter. Conclusion The “One-Code for Children’s Medical Care” family mutual-aid system, based on multiple identity authentication, effectively increased children’s outpatient visits and medical costs, thereby enhancing healthcare engagement and compliance for chronic disease patients.更多还原
