Evaluating the effect of health insurance reform on health equity and financial protection for elderly in low- and middle-income countries: evidences from China.

backgroundTo achieve Universal Health Coverage (UHC), China have implemented health system reform to expend health coverage and improve health equity. Scholars have explored the implementing effect of this health reform, but gaps remained in health care received by elderly. This study aims to assess the effect of implementing health insurance payment reform on health care received by elderly, as well as to evaluate its effect on cost sharing to identify whether improve financial protection of elderly under this reform.

methodsWe identified hospitalization of 46,714 elderly with cerebral infarction from 2013 to 2023. To examine the determinant role played by DRGs payment reform in healthcare for elderly and their financial protection, this study employs the OLS linear regression model for analysis. In the robustness checks, we validated the baseline results through several methods, including excluding the data from the initial implementation of the reform (2021), reducing the impact of the pandemic, and exploring the group effects of different demographic characteristics.

resultsThe findings proposed that implementing DRGs payment reduces drug expenses but increases treatment expense of chronic disease for elderly in China. This exacerbates healthcare costs for elderly patients and seems to be contrary to the original purpose of health care reform. Additionally, the implementation of DRGs payment reduced the spending of medical insurance fund, while increased the out-of-pocket of patients, revealing a shift in health care expenses from health insurance fund to out-of-pocket.

conclusionsThis study shares the lessons from China's health reform and provides enlightenment on how to effective implement health reform to improve health equity and achieve UHC in such low- and middle-income countries facing challenges in health financing.
