Low- and middle-income countries are considering health financing system reforms to achieve universal health coverage. This study found that transitioning from out-of-pocket dominant systems to government-financed systems had a greater positive impact on health system outcomes compared to transitioning to social health insurance. Government financing led to increased life expectancy, reduced under-5 mortality, and lower incidence of catastrophic health expenditure.
Several low- and middle-income countries are considering health financing system reforms to accelerate progress toward universal health coverage (UHC). However, empirical evidence of the effect of health financing systems on health system outcomes is scarce, partly because it is difficult to quantitatively capture the 'health financing system'. We assign country-year observations to one of three health financing systems (i.e., predominantly out-of-pocket, social health insurance (SHI) or government-financed), using clustering based on out-of-pocket, contributory SHI and non-contributory government expenditure, as a percentage of total health expenditures. We then estimate the effect of these different systems on health system outcomes, using fixed effects regressions. We find that transitions from OOP-dominant to government-financed systems improved most outcomes more than did transitions to SHI systems. Transitions to government financing increases life expectancy (+1.3 years, p < 0.05) and reduces under-5 mortality (-8.7%, p < 0.05) and catastrophic health expenditure incidence (-3.3 percentage points, p < 0.05). Results are robust to several sensitivity tests. It is more likely that increases in non-contributory government financing rather than SHI financing improve health system outcomes. Notable reasons include SHI's higher implementation costs and more limited coverage. These results may raise a warning for policymakers considering SHI reforms to reach UHC.
