Topic: Medication free text sig
James Butler (Aug 17 2016 at 21:06):
A question about mapping the sig from a C-CDA Medication Activity to MedicationAdministration. The 2015 C-CDA spec says the sig SHALL contain one text, which SHALL contain one reference, which SHOULD (?) contain a value that points to the sig in the section narrative. Has anyone mapped this to MedicationAdministration? I'm presuming the sig would become dosage.text, but what should we do with the formatting in this case? It seems like stripping out the HTML might potentially garble the meaning...

point to the resource narrative then
James Butler (Aug 17 2016 at 23:14):
Excuse my ignorance - point how?
Grahame Grieve (Aug 17 2016 at 23:19):
well, put an id attribute on a span or a div in the xhtml, and then ... hmm, where are you in the resource?
James Butler (Aug 17 2016 at 23:27):
I'm looking at MedicationAdministration.dosage.text. I know CDA docs typically have references back to narrative elements, but I wasn't aware of a similar mechanism in FHIR.
James Butler (Aug 17 2016 at 23:28):
(also any solution involving the narrative would require us to generate one, which we haven't done so far but probably should eventually...)
Grahame Grieve (Aug 17 2016 at 23:30):
we used to have a mechanism, but no one was using it so it got removd
James Butler (Aug 18 2016 at 00:13):
Ha!
James Butler (Aug 18 2016 at 00:17):
I think we're going to stringify the relevant bit of the CDA narrative into MedicationAdministration.dosage.text. @David Hay is of the opinion that any formatting of the sig is unlikely to be sophisticated enough to cause problems.
Grahame Grieve (Aug 18 2016 at 00:32):
ok
James Butler (Aug 18 2016 at 00:58):
Oh my bad it's MedicationStatement not MedicationAdministration, not that it makes any difference to the mapping
Rick Geimer (Jun 15 2017 at 16:39):
Revisiting this. I believe the mapping should now be to Dosage.text, right? Per the description of the field: "Free text dosage instructions e.g. SIG"
