On March 13, the Official Journal of the European Union (OJEU) published Regulation (EU) 2025/327 on the European Health Data Space (EHDS), a key regulation set to take effect on March 26, 2027. Its goal is to establish a framework that enables the secure and efficient exchange of electronic health data among Member States, in coordination with the General Data Protection Regulation (GDPR).
A Gradual Rollout
The implementation of the EHDS will be carried out in phases, with multiple stages of transposition. Starting on March 26, 2027, general provisions on health data management and security in the EU will take effect, along with interoperability requirements for healthcare systems.
Two years later, in 2029, the first specific requirements will be established for certain health data categories and electronic health record (EHR) systems. By 2031, these requirements will expand to include new data categories and systems. Finally, in 2035, the implementation of cross-border access mechanisms for health data will be completed.
The regulation will affect a wide range of stakeholders, including hospitals, clinics, insurers, health product and service developers, wellness applications, scientific researchers, and mortality registries. In general, any entity or professional managing electronic health data, whether public or private, must comply with new obligations regarding data collection, storage, and access.
New Requirements for Businesses
Manufacturers of electronic health record systems and wellness applications must ensure interoperability with European software and comply with a series of regulatory requirements. These include technical documentation, an information sheet, a declaration of conformity, and CE marking.
Additionally, high-risk medical devices and artificial intelligence solutions must demonstrate compliance with interoperability standards set forth in Regulations 2017/745 and 2024/1689. For interoperable wellness applications, a compliance label valid for three years will be required.
Companies accessing health data will also be subject to strict requirements. They must process information in secure environments, ensure that its use is limited exclusively to authorized purposes, and prevent any commercial exploitation. Furthermore, they will be required to guarantee transparency in data processing and access conditions.
Restrictions on the Use of Health Data
The EHDS establishes clear restrictions on the use of health data. Exploiting such data for commercial purposes is prohibited, as is any activity that could compromise public health. Unauthorized access or processing of personal data outside secure environments is also strictly forbidden.
Boosting Medical Research
One of the greatest benefits of the EHDS will be its impact on medical research. The regulation will facilitate structured and secure access to electronic health data for scientific purposes. Thanks to anonymization and pseudonymization of information in controlled environments, researchers will be able to conduct large-scale studies without compromising citizens’ privacy.
The standardization of systems and data formats will encourage collaboration between universities, healthcare centers, and industry players. Areas such as artificial intelligence and personalized medicine will particularly benefit, as access to vast amounts of data will enable the development of advanced models for disease prevention, diagnosis, and treatment.
At the same time, the regulation strengthens transparency and citizen control over the use of their data. Each individual will have the right to decide whether their medical information can be used in scientific studies, ensuring a balance between data access and the protection of individual rights.
Challenges and Opportunities for the Healthcare Sector
The implementation of the EHDS will pose a significant challenge for the healthcare sector, particularly in terms of technological infrastructure, cybersecurity, and regulatory compliance. Companies will need to make substantial investments to adapt their systems to interoperability requirements and ensure compliance with the regulation, avoiding potential penalties.
However, the new regulatory framework also presents a major opportunity for innovation. The standardization and access to high-quality data will facilitate research and the development of new medical technologies. The sector of artificial intelligence applied to healthcare, in particular, will benefit from the availability of structured, high-value data, driving more effective and personalized solutions.
A Paradigm Shift in Digital Health
Regulation (EU) 2025/327 marks a turning point in the digitalization of the healthcare sector in Europe. With a robust and unified regulatory framework, the EHDS seeks to balance data access with the protection of citizens’ rights.
Healthcare companies must start preparing now for these changes, adjusting their processes in advance to ensure competitiveness and minimize regulatory risks. The digital transformation of Europe’s healthcare system is already underway, and those who anticipate this new landscape will be the ones leading the future of innovation in the sector.
