European Health Union: An emergent reality

In this article we argue that the Member States of the European Union (EU) have consistently, since its inception, developed a shared framework to measure, monitor and intervene to improve the health status of its population, while invoking the subsidiarity principle for the health sector. As a result, a European Health Union (EHU) has been emerging insidiously and consistently, following the concept of a system for health. Using the World Health Organisation Building Blocks Framework, we analyse the normative and institutional developments related to EU citizens' health that have created a de facto EHU. Developments towards an EHU remain unequally distributed among the different building blocks analysed. The existing EHU is the result of a fragmented and incremental process, mostly grounded in governance, health intelligence and services' development. Health crisis, the Commission's agenda-setting activities and market pressures have been the most important push factors for these step-by-step processes. Health concerns have been a constant consideration in the development of the European Union (EU).EU member states (MS) have consistently developed a shared framework to measure, monitor and intervene to improve the health of their citizens.The EU system for health has a unique development pattern.The resulting European Health Union (EHU) derives from a fragmented and incremental process, mostly grounded in governance, health intelligence and services' development.Health crisis, the Commission's agenda-setting activities and market pressures have been the most important push factors for these step-by-step processes.
