D1.2 Data and metadata model

This document provides the Data model and transformation plan to assess the minimal set of variables for each use case and map the two use case model datasets with the Observational Medical Outcomes Partnership (OMOP) Common Data Model (CDM)1, the open community data standard selected by the consortium to standardise the structure and content of observational data based on the OHDSI standardised vocabularies, which allow organisation and standardisation of medical terms across the various clinical domains of the OMOP CMD. The document is articulated into 4 sections. After the Introduction, the Data assets section provides a high-level summary of the available data assets within the consortium, including clinical repositories, data sources, types and variables. In the Data modelling section, the data mapping work is reported, starting from an overview of the available data models and standards, a description of the selected OMOP CDM, and the processing of data modelling in the project, including the resulting CDM. In Conclusions, we summarise the results of this process and illustrate the next steps of the work, to be finalised in M30.
