European OHDSI Symposium 2026

The seventh European OHDSI Symposium Continuous Collaboration for Living Evidence Generation will be held in Rotterdam (NL) on April 20th, 2026, again at an inspiring location, the Steam Ship Rotterdam.

The symposium is a platform to share results and ideas about the use of the OMOP-CDM, tool development, and future research. The day will include a collaborator showcase including posters and podium presentations highlighting OHDSI’s research achievements and interactive demonstrations of OHDSI’s open-source software tools.

During the symposium, we will update you on the exciting work being done all over Europe, in National Nodes, large European Projects, and other initiatives. Like last year, we will also reserve a lot of time for networking.

We encourage people who are new to OHDSI and are interested in learning more about this exciting initiative to join our Journey. There is a slot reserved for newcomers to meet the experts in one-to-one sessions.

The main symposium will take place on Monday, April 20th, 2026, on the ship 'SS Rotterdam'.
