Topic: Free Text Dosage Quantity
Emad Elagouz (Nov 27 2018 at 22:10):
Hi team,
We are mapping between end system representation into FHIR CMM. The end system does not have coding system for dose quantity, it's simply entered as free text e.g.: "5 - 10 mg". How can we map this into Quantity? (which is the FHIR resource for Dose Quantity) https://www.hl7.org/fhir/dosage.html
[we thought of adding an extension, but maybe there is a better solution? ]
Richard Townley-O'Neill (Nov 27 2018 at 23:12):
Dosage.dose uses (eventually) quantity, which does not require the units to be coded. It does require the numeric part to be a number.
Do you need Dosage.dose to be a string?
Emad Elagouz (Nov 27 2018 at 23:30):
Yes, we need it to be a string because the data we are trying to map here is just string that can be literally anything
Richard Townley-O'Neill (Nov 28 2018 at 05:00):
My thought is Dosage.text or an extension.
Melva Peters (Nov 28 2018 at 18:25):
Dosage.text is intended for a textual representation of the full dose. For example, 5-10mg three times daily or one tablet three times daily. It isn't really intended for a part of the dose (i.e. 5-10mg). I would suggest an extension.

@Melva Peters and @Richard Townley-O'Neill thanks for both your replies...
We did use an extension . it seems the right way to go....
