Topic: MedicationAdministration dosage.dose.value with zero value
Krishna Moorthi (Sep 07 2021 at 08:28):
Hello all,
We have a question about the value associated to a medication. We authorize on the FHIR bundle generation, for a medication administration, a 0 value on the quantity. To make the smartphone app as open as possible, we'd think it is good to keep the possibility to give a medication, with a null or no quantity associated ..
And is it a good way of giving a quantity of 0 ? Or is there a better way to do this?
Thanks for your feedback on this
Regards
Krishna

There is a property MedicationAdministration.status which can be set to 'non-done' and another .statusReason where you can describe why, e.g. patient is in surgery. This is very similar to what was done in HL7v2 to indicate (especially) a scheduled administration that was not given (e.g RXA-20 - Completion Status table 0322

Null values are never allowed in FHIR instances. Agree that 'not-done' is the proper mechanism.

Thanks @Lloyd McKenzie & @John Silva

What is best practice? Status 'not-done' without a quantity/dosage (seems how cardinality is 0..1), or status 'not-done' with the originally planned quantity/dosage ?
Melva Peters (Sep 20 2021 at 12:52):
It should be the originally ordered quantity/dosage with a status of not done.

In a Clinical Research setting, there are times when a placebo is set to the value "0". This may or may not apply in this discussion.
Lloyd McKenzie (Sep 20 2021 at 13:08):
Technically, the placebo isn't a zero dose, it's a dose of a substance with zero active ingredient. You're still swallowing 1 pill, or receiving an injection of x mL.
Mike Hamidi (Sep 20 2021 at 13:35):
There are cases, unfortunately, where that "0" value needs to be explicit. In the FHIR sense, this can be explained using different contextual elements. To your point @Lloyd McKenzie
Lloyd McKenzie (Sep 20 2021 at 13:51):
It would be explicit - in the ingredients of the substance...
Robert McClure (Sep 28 2021 at 12:06):
@Mike Hamidi a placebo is a medication and represents a nonzero dose. It is wrong to pretend nothing is administered.
