Against the achievement of nearly universal coverage for social health insurance for the elderly in China, a problem of inequity among different insurance schemes on health outcomes is still a big challenge for the health care system. Whether various health insurance schemes have divergent effects on health outcome is still a puzzle. Empirical evidence will be investigated in this study.
This study employs a nationally representative survey database, the National Survey of the Aged Population in Urban/Rural China, to compare the changes of health outcomes among the elderly before and after the reform. A one-way ANOVA is utilized to detect disparities in health care expenditures and health status among different health insurance schemes. Multiple Linear Regression is applied later to examine the further effects of different insurance plans on health outcomes while controlling for other social determinants.
The one-way ANOVA result illustrates that although the gaps in insurance reimbursements between the Urban Employee Basic Medical Insurance (UEBMI) and the other schemes, the New Rural Cooperative Medical Scheme (NCMS) and Urban Residents Basic Medical Insurance (URBMI) decreased, out-of-pocket spending accounts for a larger proportion of total health care expenditures, and the disparities among different insurances enlarged. Results of the Multiple Linear Regression suggest that UEBMI participants have better self-reported health status, physical functions and psychological wellbeing than URBMI and NCMS participants, and those uninsured. URBMI participants report better self-reported health than NCMS ones and uninsured people, while having worse psychological wellbeing compared with their NCMS counterparts.
This research contributes to a transformation in health insurance studies from an emphasis on the opportunity-oriented health equity measured by coverage and healthcare accessibility to concern with outcome-based equity composed of health expenditure and health status. The results indicate that fragmented health insurance schemes generate inequitable health care utilization and health outcomes for the elderly. This study re-emphasizes the importance of reforming health insurance systems based on their health outcome rather than entitlement, which will particularly benefit the most vulnerable older groups.
在中国老年人社会医疗保险几乎实现全民覆盖的情况下,不同保险计划在健康结果方面存在的不公平问题仍是医疗体系面临的重大挑战。各种健康保险计划对健康结果是否有不同影响仍是一个谜题。本研究将对实证证据进行调查。
本研究采用具有全国代表性的调查数据库——中国城乡老年人口全国性调查,比较改革前后老年人健康结果的变化。运用单因素方差分析来检测不同健康保险计划在医疗保健支出和健康状况方面的差异。随后应用多元线性回归,在控制其他社会决定因素的同时,检验不同保险计划对健康结果的进一步影响。
单因素方差分析结果表明,尽管城镇职工基本医疗保险(UEBMI)与其他计划(新型农村合作医疗制度(NCMS)和城镇居民基本医疗保险(URBMI))之间的保险报销差距有所缩小,但自付费用在总医疗保健支出中所占比例更大,不同保险之间的差距扩大。多元线性回归结果表明,与参加URBMI、NCMS的人群以及未参保人群相比,参加UEBMI的人群自我报告的健康状况、身体功能和心理健康状况更好。参加URBMI的人群自我报告的健康状况比参加NCMS的人群和未参保人群更好,但与参加NCMS的人群相比,其心理健康状况较差。
本研究有助于推动健康保险研究从侧重于以覆盖率和医疗可及性衡量的机会导向型健康公平,转向关注由医疗支出和健康状况构成的基于结果的公平。结果表明,分散的健康保险计划会导致老年人医疗保健利用和健康结果的不公平。本研究再次强调了基于健康结果而非权利改革医疗保险制度的重要性,这将尤其惠及最弱势的老年群体。
