Topic: ValueSet from LOINC Panel?
Bob Milius (Mar 01 2021 at 23:01):
Is it possible to create a ValueSet from a LOINC panel code using compose? for example,
57021-8 "CBC W Auto Differential panel - Blood"
Michael Lawley (Mar 02 2021 at 00:31):
There are no Panel-related properties on the code or implicit ValueSets associated with Panels that I am aware of, so I believe it is not currently possible.

There are relationships to link the panel code and its member codes in LOINC.
Chris Moesel (Mar 02 2021 at 14:44):
@Lin Zhang -- I'm not familiar enough w/ LOINC specifics to know, but are those relationships surfaced in any of the LOINC properties exposed to FHIR? See: http://hl7.org/fhir/R4/loinc.html#props

Return a LOINC panel as a FHIR questionnaire
The following examples show how you can return a LOINC panel as a FHIR questionnaire using the canonical LOINC URI pattern for questionnaires: http://loinc.org/q/{LOINC #}.

@Lin Zhang Interesting that I can get a Questionnaire! But can I create a FHIR ValueSet from a LOINC panel code?
Bob Milius (Mar 03 2021 at 02:00):
It looks like LOINC can only create ValueSets from LOINC Groups (LG) and LOINC Answer Lists (LL).
Lin Zhang (Mar 03 2021 at 03:32):
At least extensional/enumerated valuesets could be created
Lin Zhang (Mar 03 2021 at 03:40):
Maybe depend on the structure of the imported content.
Lin Zhang (Mar 03 2021 at 04:36):
Current specification on valuesets make them(their expansions) as kind-of flat lists, but LOINC panels have internal tree-like/hierarchal structures possibly with more than one level.

This would be a good use for the ancestor property for filtering on multi-axial-hierarchy, but that requires Part Codes (LP) instead of panel codes.

LOINC Panel memberships are somethings more like UML Aggregation relationships but not subsumption relationships.
