Germany and the European Union (EU) are transforming health data collection and use to enable precision health through a collaborative system. Key initiatives like the European Health Data Space (EHDS) and Germany’s National Health Data Lab are central to this shift. They facilitate access to anonymised population data while ensuring privacy, creating opportunities for research, innovation and patient-centred care. As interest in artificial intelligence and digital medicine rises, Europe's approach serves as a strong model for aligning technology with public health goals.
Harnessing Federated Data for National Impact
At the national level, Germany’s use of federated data systems exemplifies how innovation can respect both legal frameworks and public trust. The National Emergency Department Data Registry is a pioneering platform that enables research access to emergency room data across the country. Operated within the German Network of University Medicine, this registry ensures that data remains locally stored while still being accessible for approved research. Because the data is not centralised, but rather analysed in a trusted research environment after proper authorisation, it adheres to both national confidentiality laws and the European Union’s General Data Protection Regulation (GDPR). This approach eliminates the need for individual consent without compromising ethical standards.

Importantly, Germany’s federal structure adds complexity: each of its sixteen states maintains its own regulations concerning health and data governance. Navigating this decentralised landscape while building a coherent national research infrastructure is a remarkable achievement. The system allows researchers to file data access requests with an independent committee that evaluates both ethical and scientific considerations. Once authorised, the data is processed in a secure environment to ensure its responsible use. This process illustrates how federated access can balance the need for broad data availability with the imperative of individual privacy.
Accelerating National Digital Health Transformation
Germany’s healthcare system is one of the most established in the world, rooted in a social insurance model introduced in the 19th century. However, in the digital realm, the country has faced challenges keeping pace with other advanced nations. The COVID-19 pandemic exposed these gaps, particularly the inefficiencies caused by fragmented data systems and outdated communication methods like fax transmissions. While other regions, such as the Canadian province of Alberta, operated fully digital emergency command centres, Germany struggled with data centralisation during the crisis.
Recognising this vulnerability, the government acted decisively. In 2020, it launched the Network of University Medicine to coordinate COVID-19 research and crisis response. Simultaneously, a €500 million Medical Informatics Initiative was introduced to improve access to life science data and accelerate research. This initiative brought together academic institutions, private companies, payors and patient advocacy groups, forming a collaborative ecosystem dedicated to enhancing biomedical knowledge and patient care.
The most ambitious development, however, is the creation of the National Health Data Lab. This platform provides pseudonymised data from approximately 75 million people—around 90% of Germany’s population—insured under the statutory health system. Its primary aim is to support research that improves healthcare delivery and system efficiency. Complementary efforts include Germany’s national artificial intelligence strategy, which promotes responsible AI use through expert engagement and impact monitoring. These coordinated actions demonstrate Germany’s determination to overcome past shortcomings and establish itself as a leader in digital health.
Establishing a European Framework for Health Data Use
Germany’s national progress feeds into a broader continental vision: the European Health Data Space (EHDS). This newly launched initiative represents a critical step in harmonising data access and governance across EU member states. The EHDS is designed to empower individuals by giving them greater control over their electronic health records while also enabling the secondary use of anonymised data for public interest, policy development and research. This dual purpose aligns individual rights with societal benefit, a balance that is increasingly important in the digital age.
To achieve this, the EHDS is developing a unified legal and technical framework to ensure compatibility between national systems. Its success depends on cross-border cooperation, the alignment of privacy regulations and the standardisation of consent and opt-out procedures. Germany’s investments and infrastructure serve as a foundation for this larger project, demonstrating how national initiatives can scale to the European level.
The EHDS reflects the EU’s belief that meaningful transnational data use is essential for advancing healthcare and life sciences. It provides a platform for sharing knowledge, supporting scientific discovery and promoting health equity across borders. If successful, the EHDS could serve as a model for other regions aiming to integrate digital health innovation with robust data governance.
Germany and the European Union are at the forefront of health data innovation, emphasising federated data access, digital infrastructure and collaborative governance. These initiatives enhance national healthcare systems and promote global cooperation. As countries aim to leverage health data for research and care improvements, Europe's model offers a valuable blueprint that prioritises security, equity and innovation.
