What are National Nodes in OHDSI Europe?
National Nodes are regional hubs — collections of research institutes, data partners, hospitals, SMEs, and other stakeholders — within a member country. Each Node is overseen by a lead institute, aligning with OHDSI Europe’s mission to empower collaborative research and advance usage of the OMOP Common Data Model. ([ohdsi-europe.org](https://www.ohdsi-europe.org/index.php/national-nodes?utm_source=openai))
How do they function?
Nodes facilitate national collaboration, data standardization, and knowledge sharing. They host regular meetings, support OMOP CDM transformations and data quality work, organize workshops, engage policy makers, and help launch observational studies.
