Following their presentations on building health data ecosystems (Mattias Fredricson and Mona Heurgren), XpanDH Project lessons (Henrique Martins), Luxembourg's EHDS implementation approach (Dmitry Etin), and cancer research data initiatives (Åslaug Helland), the panelists will explore how these diverse yet complementary approaches can overcome the challenges of data fragmentation, quality issues, and inconsistent implementation. The discussion, moderated by Henrique Martins, will examine practical strategies to ensure EHDS delivers tangible benefits rather than becoming "just another law we criticize"—focusing on interoperability solutions, governance models that bridge primary and secondary use cases, and quality frameworks that enhance data utility. Representing perspectives from national implementation, research applications, EU project experience, and Commission oversight, the panel will identify critical success factors for ensuring health data works effectively across boundaries, sectors, and use cases. Attendees will gain insights into actionable approaches that can accelerate the EHDS journey toward a purpose-driven implementation that truly serves patients, researchers, and healthcare systems across Europe.
