Tutorials registration

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

1. 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. 

2. 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.
