A federated network of Data Partners

The EHDEN project aims to collaborate with diverse institutions, data sources and data custodians across the EU, with a goal of harmonising source data to the OMOP common data model locally, within a federated network.

Following the 6 open calls to date we have organised, we currently have 166 Data Partners from 27 different countries which are mapping their data to the OMOP common data model. This includes several EHDEN project partners who have also mapped their data to the OMOP CDM for use in the federated network.

We are looking forward to extending this further via subsequent open calls.

Our EHDEN Portal with a Data Partner Catalogue and Feasibility Dashboards (for those who have completed their mapping to the OMOP CDM) is live, with more information here.
