Medical Debt and Catastrophic Health Expenditures among Middle- and Low-Income Families in China

Abstract Background Medical debt is a persistent global issue and a crucial and effective indicator of long-term family medical financial burden. This paper fills a research gap on the incidence and causes of medical debt in Chinese low and middle-income households.Method Data was obtained from the 2015 China Household Finance Survey and medical debt measured as borrowings from families, friends and third parties. Tobit regression models were used to analyze the data. The concentration index was employed to measure the extent of socioeconomic inequality in medical debt incidence.Results We found that 2.42% of middle-income families had a medical debt, averaging US$6278.25, or 0.56 times household yearly income; and 3.92% of low-income families had medical debts averaging US$5419.88, which was equivalent to 2.49 times household yearly income. The concentration index for low and middle-income families’ medical debt was significantly pro-poor. Medical debt impoverished about 10% of all non-poverty households and pushed poor households deeper into poverty. While catastrophic health expenditure was the single most important factor in medial debt, age, education, and health status of householder, hospitalization and types of medical insurance were also significant factors determining medical debt.Conclusions Using a narrow definition of medical debt, the incidence of medical debt in Chinese low and middle-income households was relatively low. But, once medical debt happened, it imposed a long-term financial burden on medical indebted families, tipping many low and middle-income households into poverty and imposing on households several years of debt repayments. Further studies need to use broader definitions of medical debt to better assess the long-term financial impact of medical debt on Chinese families. Policy makers need to modify basic medical insurance schemes to manage out-of-pocket medical expenses better and take account of pre-existing medical debt when addressing this problem.
