Topic: serial number extension
Richard Townley-O'Neill (Mar 04 2021 at 06:04):
Is there a common extension for serial number? I haven't found one.
We want to record vaccine vial serial number in Immunization (for covid of course), as well as lot number.
It seems that a lot of places will define similar extensions.
Could this be an R5 extension?

It would go in Medication.identifier. You just probably wouldn't know the 'system'.
Richard Townley-O'Neill (Mar 04 2021 at 06:10):
Immunization identifies the vaccine with Immunization.code (CodeableConcept), so it has no way to say which instance of Medication describes what is administered.
Richard Townley-O'Neill (Mar 04 2021 at 06:11):
It seems that systems do not treat immunisation as a variation of administering a medication.
Richard Townley-O'Neill (Mar 04 2021 at 06:12):
Maybe an extension to point to the medication? But lot and expiry date are already in Immunization.
Richard Townley-O'Neill (Mar 04 2021 at 06:12):
So Immunization contains what is wanted from Medication, without referring to that resource.

I haven't previously heard about a need to store a vaccine dose serial number (presumably this is one layer more granular than the lot number (eg a vial number)). Jose has been advocating for either making Immunization.code a CodeableReference to allow a pointer to Medication or creating a new element for such a reference. We had decided on one of the FHIR Workflow calls (I think that was the forum anyway) that this wasn't needed, but maybe we need to revisit that decision.
Richard Townley-O'Neill (Mar 04 2021 at 23:52):
The serial number is a vial serial number, not a dose serial number. In Australia Pfizer and AstraZeneca vaccines are in multi-dose vials.
Richard Townley-O'Neill (Mar 04 2021 at 23:53):
We expect to use an AU Base extension as we need this quite soon.

The Belgian vaccine profile supports all that.
Jose Costa Teixeira (Mar 05 2021 at 00:00):
We have a AdministeredProduct with a reference to Medication, where we can keep the serial number

Do you do discourage using lotNumber and expirationDate in Medication as they are must support in Immunization?
Richard Townley-O'Neill (Mar 05 2021 at 03:42):
Do you use Medication.identifier.type to indicate that the serial number is a vial identifier?
