ETL library

Across the OHDSI community, transforming patient-level observational data into the OMOP common data model is a foundational task every data holder has to perform. The ETL specifications and source code that document the transformation process are invaluable artifacts to promote greater transparency in observational research, and also provide others in the community with useful worked examples to support their own development.

We will post ETLs to the OMOP CDM on this page as they are contributed by the community, so check back regularly…
