2022 OHDSI European Symposium

The 2022 OHDSI European Symposium was held June 24-26 on the SS Rotterdam in the Netherlands. More than 350 collaborators gathered together for the community’s first in-person symposium since the COVID pandemic to connect, share research, and learn from each other. 

Among the topics during the symposium was the use of the OMOP-CDM, tool development, and future research. The first day included a collaborator showcase which featured both posters and podium presentations to highlight OHDSI’s research achievements, and interactive demonstrations of OHDSI’s open-source software tools.

The symposium also contained a “Cruise Around Europe” session in which representatives from 10 different European nations provided updates on the exciting work that is being done all over the continent, including National Nodes, large European Projects, and other initiatives.

There were also presentations given by both Erica Voss (Characterizing Adverse Events in COVID-19 infected patients across the OHDSI network) and host Peter Rijnbeek (Data Analysis and Real World Interrogation Network (DARWIN EU®)), as well as a reaction panel. The videos from Day 1 are all available below.

The rest of the weekend featured workshops and workgroup meetings.

Several leaders and participants from the symposium shared some perspectives from the event, as well as about their own respective journeys with OHDSI. You can watch those interviews here. Other videos from the final two days of the symposium will be posted when available.
