European Health Data Space: EHDS set to revolutionise how health data is used and exchanged across its Member States

The European Health Data Space (EHDS) is a foundational initiative by the European Union (EU) to revolutionise how health data is used and exchanged across its Member States. It's a cornerstone of the European Health Union and the first common EU data space specifically dedicated to a single sector, as part of the broader European strategy for data.
In essence, the EHDS aims to establish a common framework of rules, joint standards and practices, infrastructures, and a robust governance framework for electronic health data across the EU.
The EHDS operates on two main pillars for the use of electronic health data:
Primary Use (for Healthcare Provision):
Empowering Citizens: It gives individuals greater control over their electronic health data, allowing them to access, manage, and share their health records electronically across EU borders. This means, for example, a patient from one EU country could easily share their medical history or prescriptions with a doctor in another EU country, facilitating continuity of care.
Cross-border Healthcare: It aims to enable healthcare professionals to access relevant patient data (with patient consent) from other Member States, improving the quality and safety of cross-border medical care. The existing MyHealth@EU infrastructure serves as the digital backbone for this cross-border exchange.
Reduced Administrative Burden: By standardizing data exchange, it seeks to reduce bureaucracy and improve efficiency in healthcare delivery.
Secondary Use (for Public Interest, Research, and Innovation):
Facilitating Research: The EHDS will make electronic health data more easily available for scientific research, particularly in areas like public health, rare diseases, and the development of new treatments and medicines (including AI-driven health research). Data will typically be accessed in anonymised or pseudo anonymised formats.
Policy Making: It will enable better data-driven policymaking and decision-making at national and EU levels, allowing for more effective responses to health crises and the development of public health strategies.
Innovation: By providing access to high-quality, structured health data, the EHDS is expected to spur innovation in the health sector, encouraging the development of new digital health applications, medical devices, and AI systems.
Strict Safeguards: The framework includes robust privacy safeguards, ensuring that health data is pseudonymized or anonymized before being made available for secondary use. Patients will generally have the right to "opt-out" from having their data used for secondary purposes, though implementation details of this opt-out mechanism are left to individual Member States.
Timeline and Implementation:
The EHDS Regulation (EU) 2025/327 officially entered into force on March 26, 2025, marking the beginning of the transition phase.
March 2029: Key obligations related to the new health data rights (primary use) and the new pathway for secondary use will come into effect. This includes the establishment of national Health Data Access Bodies (HDABs) in each Member State, responsible for overseeing and granting access to health data for secondary purposes.
March 2031: The system for primary use will expand to include a wider range of data categories (e.g., medical imaging, lab results). Rules for secondary use will also apply to additional data categories (e.g., genomic data).
March 2034: Countries outside the EEA and international organisations may be able to apply to join HealthData@EU for secondary use.
The European Commission will also be developing numerous implementing and delegated acts over the coming years to provide detailed rules and technical specifications for the EHDS's operationalisation.
Benefits:
Empowered Citizens: Greater control and access to their own health data.
Improved Healthcare: Better diagnosis, treatment, and continuity of care across borders.
Accelerated Research: Easier access to data for scientific breakthroughs.
Enhanced Innovation: New opportunities for digital health companies and MedTech.
Stronger Public Health: Better data for monitoring and responding to health challenges.
Reduced Fragmentation: Harmonisation of health data standards across the EU.
Challenges:
Interoperability and Standardisation: Harmonising disparate electronic health record (EHR) systems and data formats across Member States is a massive undertaking.
Data Security and Privacy: Ensuring robust protection for highly sensitive health data, managing consent, and implementing opt-out mechanisms effectively.
Implementation Burden: Significant investment and effort required from healthcare providers, data holders, and national authorities to comply with the new regulations
.
Intellectual Property and Trade Secrets: Balancing data sharing for public good with the need to protect sensitive commercial information from private entities.
Fragmentation in Implementation: While the regulation aims for harmonisation, some aspects (like the opt-out mechanism) are left to Member States, potentially leading to divergent approaches.
The European Health Data Space is an ambitious and transformative undertaking with the potential to fundamentally reshape healthcare and health research within the EU, fostering innovation and ultimately improving patient outcomes.
