Check out this recently published JMIR paper by Clair Blacketer (PhD student in HDS group) offering a comprehensive overview of the data sources within the European Health Data & Evidence Network (EHDEN), focusing on the 210 health data sources from 30 countries mapped to the OMOP Common Data Model. It highlights the diversity and scale of real-world data across Europe, illustrating the potential of federated data networks to enhance the generation of reliable evidence. By emphasizing the breadth of data within the network, this work underscores how these resources can be leveraged to support future health research and improve the generalizability of evidence.
