Mapping Barts Health NHS Trust electronic health record to the OMOP data model


The European Health Data and Evidence Network (EHDEN), an IMI 2 consortium with 23 partners, is a multi-stakeholder, interdisciplinary, open-science collaborative maximising the value of health data through large-scale analytics.

With hundreds of researchers from across Europe and health records for about 100 million unique patients, EHDEN seeks to improve health by generating insights and evidence from real-world clinical data at scale, to support patients, clinicians, payers, regulators, governments, and the industry in understanding wellbeing, disease, treatments, outcomes and new therapeutics and devices.

EHDEN’s mission is to provide an new paradigm for the discovery and analysis of health data in Europe, by building a large-scale, federated network of data sourecs standardized to a common data model.


Barts Health NHS Trust is the largest NHS hospital group or Trust in the UK, comprising six hospitals. The hospitals serve the ethnically diverse communities of over 2.6 million people in East London.

Through undertaking this work, Barts Health will become a data partner within the EHDEN federated network. The data source for this project is the single co-ordinated Trust data warehouse comprising of the secondary care electronic medical record of each of the hospitals. The warehouse also brings together several other electronic healthcare systems utilised in the delivery of clinical care for our patients including pathology, radiology and local cancer registries. The Trust has joined an East London Partnership with primary care (GP practices) to develop a single integrated data service which has been named Discovery.

Barts Health anticipate that joining EHDEN as a data partner will deliver both on key strategic objectives of the Barts Life Sciences Initiative and provide a valuable resource for other data partners within the EHDEN collaboration. In joining the network, we will make be able to bring the depth and breadth of the data available to a wider research community for the benefit of our patients.

Aims & Objectives
