Friends:
Lots of ideas here.
Yes, ATC is clear. But relationships between drugs and indications (which look like Conditions) are not, or within LOINC from surveys and their answers, etc. The naming convention of the relationship help, but only if you know what’s behind and read the (unfinished) documentation. But yes, it’s better than nothing, I agree.
That would work in some, but not all. SNOMED has a rich inner-vocabulary system of relationships. But we are actually trying to get away from vocabularies as the main principle of organization, and favor domain-based relationships instead. Take RxNorm. That is a closed system, but only works in the US. In other countries, you’d have to use a RxNorm/RxNorm Extension combination. Drugs and their classifications are equally cross-vocabulary.
Not sure. First, use domains, instead of vocabularies. But even those: The relationships between Indications (Drug domain) and SNOMED (Condition) is crossing all boundaries, and there are use cases.
That may be true. Because inner-vocabulary realtionships are mostly manual, and therefore not excessive. Let me find out.
It does.
