EHDS (European Health Data Space) is an EU initiative designed to create a secure and standardized framework for sharing and reusing health data across European Union member states. The aim is to empower individuals with control over their health data, improve healthcare delivery, and foster innovation in medical research. EHDS ensures privacy, security, and interoperability by establishing strict governance and technical standards. It supports primary use (healthcare provision) and secondary use (research, policy-making) of health data, while complying with GDPR and other relevant regulations. EHDS is a cornerstone for a digital, patient-centered European health ecosystem.
