Summary of the Proposed Research:

The Observational Health Data Sciences and Informatics (OHDSI) collaborative is an organization focused on harmonizing observational health datasets. As part of this effort, the group has instituted a data model called the Observational Medical Outcomes Partnership Common Data Model (OMOP CDM) designed to describe a common data format for these datasets.

This project is to evaluate how revisions to OMOP CDM represents clinical trial data from the Vivli database, and identify potential information that is not currently captured in the model revision proposals.

Clinical trials test potential treatments in human volunteers to see whether they should be approved for wider use in the general population. A treatment could be a drug, medical device, or biologic, such as a vaccine, blood product, or gene therapy. Different data submission standards have been adopted by governing agencies in different countries and geographical regions, including the United States of America (USA) Food and Drug Administration (FDA), the European Commission (EC) European Medicines Agency (EMA), Japan Pharmaceuticals and Medical Devices Agency (PMDA), and China National Medical Products Administration (NMPA).  These different data representations create challenges for researchers to systematically analyze clinical trials across these data sources to either re-evaluate the original hypothesis or explore data for new discoveries.

The Observational Medical Outcomes Partnership (OMOP) Common Data Model (CDM) provides a possible solution to enable such systematic examination by transforming/standardizing these heterogeneous data sources into one common representation (terminologies, vocabularies, coding schemes.)  However, information unique and crucial to clinical trials, such as study information and arm design, is not currently modeled in OMOP CDM. Through preliminary study on synthetic clinical trials datasets, we have identified eight areas to be enriched in OMOP CDM to harmonize existing clinical trial submission data standards.  With selected clinical trials from Vivli, we will validate these eight areas to be revised in OMOP CDM to capture clinical trials data thoroughly, evaluate data elements within each area, and identify new areas or data elements based on real world datasets.
