Hello!
I am currently trying to implement custom Concept IDs and custom Drugs.
The old OMOP homepage shows a page about OSCAR & GROUCH, which may be useful for my future work.
Unfortunately OSCAR is only available for CDM v4 and the link to the GROUCH Source Code is not working. ( http://omop.org/GROUCH )
Are these tools still available ?
Thanks for any help.
Best Regards, Deniz
