Their core work

EOPYY is Greece's national health insurance and healthcare services organization — the body responsible for managing public health coverage for the majority of the Greek population. Their core function is administering healthcare service delivery, reimbursement, and the administrative data that flows from a national-scale health system. In EU research contexts, they serve as a real-world health system partner: providing access to population-level administrative claims data, operational insights from running a national payer system, and grounding for public health policy research. They are not a research lab — they are a data asset and a policy anchor for projects that need evidence from Southern European health systems.

What they specialise in

How they've shifted over time

Their H2020 participation moved from applied data innovation to formal research infrastructure. In the earlier project (CrowdHEALTH, 2017–2020), the focus was on exploiting collective or crowdsourced health data to inform policy — a more experimental, data-driven angle. By PHIRI (2020–2023), the emphasis had shifted to structured research infrastructure: standardized data models, metadata standards, and international comparisons, with COVID-19 as the urgent driver. The trajectory points toward EOPYY becoming a recognized national node in European health data spaces rather than just a policy operator.

EOPYY is evolving from a passive data contributor into a structured participant in European health data infrastructure, making them a relevant partner for projects aligned with the European Health Data Space (EHDS) agenda.

How they like to work

EOPYY has participated exclusively as a consortium member — never as a project coordinator — which reflects their role as a data and policy anchor rather than a research driver. Both of their projects were part of very large international consortia: together they account for 59 unique partners across 33 countries, suggesting EOPYY joins broad, multi-country research networks where their value lies in what they can access and validate, not in leading technical work. For potential partners, this means they are likely to be a cooperative, low-overhead participant who contributes real-world data access and national health system credibility.

Despite only two projects, EOPYY has built connections with 59 distinct consortium partners across 33 countries — an unusually broad network for such a small project portfolio, indicating they joined large European research consortia with wide geographic representation. Their network is pan-European with no obvious geographic concentration beyond their Greek base.

What sets them apart

EOPYY holds a position that few academic or private research partners can replicate: they are the Greek national health payer, with direct operational access to population-scale administrative health data covering millions of people. For any project needing real-world evidence from a Southern European public health system — reimbursement data, service utilization records, population health registries — EOPYY is one of the shortest paths to that data. Their participation also signals policy-level buy-in from a national authority, which strengthens consortium credibility in health research proposals.

Highlights from their portfolio

• CrowdHEALTH
  The largest of their two projects by funding (€145,312), addressing the innovative use of collective health intelligence for shaping public health policy — an applied, policy-facing framing rare for infrastructure bodies.
• PHIRI
  A COVID-19-driven population health infrastructure project that positioned EOPYY as a national data node within a European cross-country comparison framework, directly relevant to the emerging European Health Data Space.
