About the Symposium


We are proud to announce the formation of the European OHDSI Chapter led by Erasmus University Medical Center The Netherlands.

We like to strengthen the European contribution to the global OHDSI community. Europe should contribute in tool development and also of course participate in large global studies that have not been possible before. Furthermore, we need to educate all the stakeholder to guarantee high quality in data transformation and usages. The annual OHDSI symposium is a perfect instrument to gain momentum, inform, and enlarge the European OHDSI community.

The first annual symposium will take place March 23th in Rotterdam and tutorials will be offered on March 24th.

Two full-day tutorials will be offered on March 24th in the educational center.

OMOP-CDM and Standardized Vocabularies Tutorial

Faculty: Christian Reich, Erica Voss, Mui van Zandt

This tutorial will discuss all the details on the structure of the OMOP-CDM and the Standardized Vocabularies that are used to harmonize terminology. An important part of this tutorial is on how to transform your own dataset to the OMOP-CDM.

Target Audience:Data holders who want to apply OHDSI’s data standards to their own observational datasets and researchers who want to be aware of OHDSI’s data standards so they can leverage data in OMOP CDM format for their own research purposes.

OHDSI Tool Ecosystem

Faculty: Patrick Ryan, Peter Rijnbeek, Jenna Reps, Martijn Schuemie

This tutorial will in detail discuss the tool ecosystem of OHDSI with a focus on the impressive functionality in ATLAS, such as vocabulary browsing, cohort definitions, risk effect estimations, patient-level prediction, and more.

Target Audience:Data holders, researchers, and regulators who want to learn more about the exciting tools developed by the OHDSI community.

Time Description
8:30 – 9:00am Registration
