I’m trying to map our ECMO patients and am kind of stuck. I have plenty of physical objects that have to go along together since and ECMO consists of filters, cannulas, the pump etc.etc.
Since DEVICE_EXPOSURE doesn’t allow nested relationships - what would be the best way to get everything together nicely? The only way I see right now is to use the FACT_RELATIONSHIP table where I would have to use non-standard concepts (which I assume is bad?).
I also have to map a “stop reason” if anything goes wrong with the ECMO. DRUG_EXPOSURE has the nice stop_reason attribute which is, unfortunately, missing in the DEVICE_EXPOSURE table. Can I propose such a column for an upcoming OMOP version here?
Thank you all for your hard work on improving such a great data model!
