Abstract:
Heterogeneous data formats complicate unified analysis in multisite clinical studies. Standardizing data in the Observational Medical Outcomes Partnership (OMOP) Common Data Model (CDM) requires Extract-Transform-Load (ETL) processes, which are complex and time-consuming to develop, especially with different source data specifications. The aim of our work is to develop a generalized, metadata-driven ETL process to transform Fast Healthcare Interoperability Resources (FHIR) into OMOP CDM. In this paper, we present first results of the developed metadata-driven ETL process on the example of two different Patient FHIR specifications.

Health Information Technology, commonly called HIT, integrates advanced information systems and technology in healthcare settings. Its primary functions include:
Methods of Documentation I: Source-Oriented Records
In an SOR, each discipline involved in patient care maintains a separate medical record section. This record-keeping method enables easy tracking of patient progress and ensures healthcare staff have access to up-to-date information.
Key Attributes include the following:
