Abstract
Under the influence of concerns about sustainability, health system reforms have targeted institutional designs and have overlooked the role of socio-political factors like solidarity—a concept that is generally assumed to underpin the redistributive health system. The purpose of this research is to investigate users’ perceptions of the National Health Insurance as a system, their senses of solidarity and their views on the sustainability of the system in Taiwan. Using the descriptive ethics approach, qualitative in-depth interviews were conducted with typical case sampling of 17 participants in the Taipei Metropolitan. The framework approach was used to analyze the interview transcripts. The research finds that despite great differences between users’ perceptions of the NHI, most users could share a notion of mutual relationship among each other. Three types of reasons are used to justify the obligations of mutual aid imposed by the NHI. These reasons are embedded within divergent conceptions of solidarity. The research also finds that government’s performance, the stability of decision-making and users’ personal experiences engaging with the system are important conditions for the users’ supportive attitude toward the system. Solidarity is a plausible concept in sustaining a non-Western social health insurance such as Taiwan’s NHI.
