2023 Europe Symposium

The 2023 Europe Symposium, held July 1-3 in Rotterdam, featured the widest breadth of research ever shared at the European event, and it also hosted several plenary talks and national updates to show how strong the community continues to grow.

The main conference included several talks, including sessions focused on European Initiatives Using the OMOP CDM and Data Analysis and Real World Interrogation Network (DARWIN EU®), as well as 10 lightning talks focused on OHDSI Community Evidence. Videos of all talks will be posted on this homepage when available.

The event welcomed a record number of submissions to the Collaborator Spotlight, including 45 posters on observational data standards and management, 28 on clinical applications, 11 on methods research and five on open-source analytics development. The full list of titles and most of the actual posters can be found on the Europe Showcase homepage. A full recap of the event was shared during the July 11 community call; you can watch that presentation here.
