Objectives:

The idea of the OMOP CDM is to create a representation of the source data in such a way that queries and tools can be run more or less blindly (without access to the data) and still return the correct result. This works if the format (table structure) and the vocabularies (coding schemas) are all standardized. Achieving this allows developing standardized tools and methods and drive quality, reproducibility and efficiency, and thus gets us closer to fulfilling the OHDSI objectives2.

And it does really work. Except not quite 100%. There are still a good number of issues, which despite the CDM and vocabularies the exact choice of representing a clinical event or circumstance can be ambiguous, arbitrary, clumsy.

Audience:

Everybody who has an interest in OMOP CDM ETL, data quality and quality certification.

Project Leads: Asha Mahesh, Minnie Chou, Greg Klebanov, Christian Reich
