If it doesn’t exist, I would be interested in helping create a browser for seeing what metadata exists across study sites.
As an example use case, I need access to biomarker data tied to genetic information and health outcomes, and I am not sure how to find it in the OHDSI system. (In the UK Biobank it is clear how to access this information.)
At ohdsi.org under the Resources or ‘New to OHDSI?’ sections, I couldn’t find a similar interface for browsing metadata across OHDSI sites.
There you can see concepts and relationships between Questions and Answers, Variables and Values, and it rolls up to Categories.
Health outcomes are stored in a datasets which aren’t publicly available althought they are integrated into some clinical data.
@jaan, The concept prevalence study results might be helpful. The PHOEBE application will show you how many databases and records exist in a subset of the OHDSI network for any given concept.
