In March 2021, OHDSI and HL7 announced a collaboration to unify their common data models. (Full disclosure, one of the leaders of this collaboration is our very own Grahame Grieve).
We have previously discussed how FHIR and OMOP standards (or common data models) serve different purposes. However, there is no reason for their data models to be different, although this doesn't mean it will be easy to do.
The collaboration recognizes the unmet need and the increasing desire to use real world data to improve patient care. A cause that Evidentli is very passionate about. We are looking forward to unification of these two data standards which, for the many health systems that use FHIR, means data will be one step closer to being research-ready. Of course, having the data in OMOP is just the start of using real-world data for improvement of care. Ethical management of such data is critical and self-serve clinical analytics are required to overcome the evidence shortage at scale and to rapidly translate real world data into better care.
