Secondary Use of Health Data: From Regulation to Reference Implementation – The TEHDAS2 & GR-HDAB experience

This session examines the secondary use of health data under the European Health Data Space (EHDS), focusing on how European cooperation frameworks and coordinated national efforts are shaping implementation in practice.

Building on the EHDS regulatory framework, the discussion will explore the role of EU-level collaboration mechanisms—including HealthData@EU, the EHDS Community of Practice, and the TEHDAS2 Joint Action—as key enablers for shared methodologies, reference work, and alignment across Member States.

At national level, the session will highlight how countries are translating this collective European work into concrete institutional, governance, and technical set-ups, drawing on ongoing national initiatives such as GR-HDAB, alongside comparative perspectives from other Member States.

Rather than focusing on future implementing acts, the session aims to clarify what is already being prepared today: governance models, coordination structures, reference implementations, and enabling infrastructures that support the gradual and coherent roll-out of secondary use of health data across Europe.
