Thailand’s universal health coverage reform as a policy process roadmap for countries pursuing bold health system change

Abstract Efforts to achieve universal health coverage (UHC) in low- and middle-income countries often face structural, political, and institutional barriers. This article analyzes a case of rapid national health reform that expanded coverage across an entire population, despite limited fiscal resources. Drawing on Kingdon’s Multiple Streams Framework alongside Punctuated Equilibrium Theory as organizing frameworks, this analysis examines how problem recognition, technical policy development, and political alignment converged to enable transformative health policy change. Key contributors to success included long-standing work by health system reformers, supportive civil society mobilization, and strategic engagement by political actors. The case offers broader lessons for advancing health reforms elsewhere, including the value of early technical preparation, coalition-building across sectors, and seizing policy windows when conditions align. It also underscores the importance of balancing rapid implementation with system capacity and stakeholder engagement to ensure reform sustainability.
