Real-World Data Process Workflow and Real-World Data OMOP Common Data Model v5.4

The Observational Medical Outcomes Partnership (OMOP) is an open-source industry standard used to transform data from disparate databases into a Common Data Model (CDM).

OMOP is created by the Observational Health Data Sciences and Informatics (OHDSI) initiative, a collaborative group, and data network. The OHDSI initiative aims to improve health by empowering a community to collaboratively generate evidence that promotes better health decisions and better care.

OMOP is a person-centric relational data model where for each record, the person, and date are required at minimum. All content is mapped or transformed to OMOP standardized vocabularies that correspond to standard healthcare concepts. The original source data are stored to ensure minimal information loss.

The process of converting Oracle EHR Real-World Data (OERWD) to the OMOP CDM v5.4 includes mapping proprietary data to OMOP standard concepts. Custom mappings are applied when proprietary terms do not have corresponding OMOP standard concepts. Following the mapping process, an extraction, transformation, and loading (ETL) code is developed to convert the dataset.
