Topic: LOINC Answer list
David Hay (Jun 19 2017 at 01:12):
On this page https://www.hl7.org/fhir/dstu2/loinc.html#alist there's an example of a reference from a questionnaire to a LOINC Answer list that looks like this:
<options>
<reference value="http://loinc.org/vs/LL715-4"/>
</options>
This confused me as I understood a reference like that to be a resolvable reference (relative or absolute) to - in this case - a ValueSet resource whereas this looks more like a 'canonical' reference that doesn't need to resolve. What am I missing?
Grahame Grieve (Jun 19 2017 at 02:49):
it's an implicit LOINC value set - see http://hl7.org/fhir/loinc.html#implicit
David Hay (Jun 19 2017 at 11:39):
Sorry, I'm still unclear. Will the value of the reference element resolve to an actual valueset that can then be examined/expanded whatever...
Grahame Grieve (Jun 19 2017 at 12:09):
in principle it should, and LOINC intend that it will. In the meantime, you can ask a terminology server to expand anyway
Grahame Grieve (Jun 19 2017 at 12:09):
most should do LOINC implicit value sets
