The Institute collaborates with the Observational Health Data Sciences and Informatics consortium (ODHSI), an international consortium of researchers that has developed an open-source common data model that allows for the systematic analysis of disparate observational databases. The common data model adopted by the consortium is the Observational Medical Outcomes Partnership (OMOP). This links varying health systems’ coding systems to a standardized vocabulary, with minimal data loss.
More than 2,300 individuals at dozens of universities, institutes, and companies across 74 countries collaborate with ODHSI, making it possible for participating consortium members to draw cohorts and conduct inquiries at a national or international scale.
Once a database has been converted to the OMOP common data model (CDM), research can be conducted using standardized open source as well as proprietary analytical tools. The OMOP CDM can accommodate disparate sources of electronic data including but not limited to:
- Administrative claims
- Registry data
This facilitates various types of research including safety surveillance, comparative effectiveness, quality of care, cohort characterization studies, population-level estimation studies, and patient-level predictive modeling.
Mapping clinical data to the OHDSI OMOP common data model
We are working with University Hospitals/Cleveland to validate mapping their clinical data to the OHDSI OMOP common data model. This supports their health system-specific research and will facilitate CICB/UH collaborating researchers’ access to the OHDSI consortium’s datasets with which researchers can initiate or participate in inquiries at a regional, national, or international scale.
The Book of OHDSI
The CICB hosted the 2019 face-to-face OHDSI meeting that lead to the completion of The Book of OHDSI, the first textbook from the OHDSI collaborative which provides clear documentation of its model, representation, and processes. Learn more about the Book of OHDSI here.
