Universal health care in middle-income countries: Lessons from four countries

BACKGROUND: In this paper, we review lessons learned about Universal Health Coverage (UHC) in middle-income countries, with specific reference to achievements and challenges observed during recent years in four middle-income to upper-middle-income countries - Mexico, Turkey, The Republic of Korea and Ukraine. Three of these countries - Mexico, the Republic of Korea, Turkey are members of the Organization for Economic Cooperation and Development (OECD). Ukraine has aspired to join Western institutions like the OECD since its independence in 1991. METHODS: The research included a combination of cross-sectional and longitudinal reviews of both statistical and contextual data, available from both published sources and available "grey literature" reports. RESULTS: constitutional guarantees and national health legislation are often a necessary but do not constitute a guaranteed path to success without accompanying institutional measure to secure sustainability (political and economic) and supply and demand constraints in service provision and consumer/patient behavior. De facto, in most countries expansion in health insurance coverage does not happen "with the stroke of a pen" but require years of commitment and efforts to change the supply and demand after critical legislation has been enacted. Fourth, two major approaches dominate: incremental and "big bang" health system reforms. CONCLUSIONS: We caution against the pitfalls of over-attribution from drawing too strong conclusion from individual longitudinal country experiences ("over-determinism") and over-generalization from broad sweeping cross-sectional statistical analysis ("reductionism"). Every country is different and needs to find its own path towards UHC considering their contextual specificities, learning from the achievements and failures of others, but not try to copy their experiences.
