Join the 2026 European OHDSI Symposium in Rotterdam – workshops April 18–19, main symposium April 20.

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 to highlight 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 to learn 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. Saturday, April 18th, and Sunday, April 19th will be dedicated to workshops and workgroup meetings, to be held in the Education Centre of the Erasmus University Medical Center, Rotterdam, The Netherlands.
