From health systems to systems for health: much more than semantics

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.

Building-blocks to develop one health systems

Notwithstanding the understandable rationale of the logical, expected and natural evolution of human behaviour towards an anthropocentric view of its relationship with other animals and the environment, a shift from this predatory "Ego-centric" behaviour towards an "Eco" conduct, with regard to their view of the world and of the global health, has become mandatory, contributing to the development of the "One Health" and of "One Health Systems" concepts. We contend for the usefulness of a building-blocks approach to facilitate an understanding of the development of One Health Systems. We assert that a building-blocks approach to One Health Systems with strong similarity to WHO's building-blocks for human health systems would help to strengthen the case for robust,resilient and anti-fragile One Health systems.
