General Information

OHDSI’s mission is to improve health, by empowering a community to collaboratively generate the evidence that promotes better health decisions and better care. As a community we envision a world in which observational research produces a comprehensive understanding of health and disease. OHDSI promotes a collaborative approach to research and has rapidly grown into a vibrant international community. Everyone is welcome to actively participate in OHDSI, whether as a patient, a health professional, a researcher, or someone who simply believes in our cause.

2018 2019 2022

The third European OHDSI Symposium will be held in Rotterdam (NL) on June 24th 2022 (new date!!), this time at a very exciting location, the Steam Ship Rotterdam. This year's symposium is entitled “We'll meet again for one journey ahead!” because we think it is very important to enjoy each others company again in real life as we did in 2018, 2019.

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.

This year's symposium will contain a "Cruise around Europe" session in which we will update you on the exciting work that is being done all over Europe, in National Nodes, large European Projects, and other initiatives. We will also reserve a lot of time for networking this year, something we all have missed.

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 Friday June 24th 2022 at the ship SS Rotterdam. Saturday June 25th, and Sunday June 26th will be dedicated to workshop and workgroup meeting, to be held in the Education Centre of the Erasmus University Medical Center, Rotterdam.
