'Drug Therapy' v 'Administration of Drug'

Dear All,

We are looking for group opinions and feedback on the use of 'Administration of drug (procedure)' versus 'Drug therapy (procedure)' concepts. 

An overview of the topic was presented in the Seoul meetings in Oct 2024 - including detailed background and logging of use-cases. The presentation is attached to this thread. 

A recent content request has highlighted the challenge in the area: 

68322007 |Administration of antibiotic (procedure)| was added to the terminology in 20220930

281789004 |Antibiotic therapy (procedure)| was added to the terminology in 20100131 which means it likely has more data associated with it.

The modeling of the two concepts is identical and both are marked as defined, so I am not sure how this is not being flagged by either an RVF or DROOLs validation check.

If these are not considered duplicates, then 281789004 |Antibiotic therapy (procedure)| should be remodeled, a new semantic tag of (Regimen/Therapy) assigned , and the concept moved to the regimen/therapy sub-hierarchy.

The assumed difference between these concepts may be a single administration of one dose of an antibiotic versus a course of treatment (e.g. Z-pac), but I am not even certain that is the case.

The entire << 416608005 |Drug therapy (procedure)| being in the procedure hierarchy is questionable given the creation and existence of the (regimen/therapy) semantic tag and sub-hierarchy.

The use-case logging in Seoul identified that some countries are actively using these concepts - if any group members have experience with implementing these concepts, or ideas on the issue please share.
