Topic: AllergyIntolerance's additional properties
Jane Pankratova (Feb 17 2021 at 14:14):
Hello everyone,
I have a few questions about how to fill some properties in FHIR Resource - AllergyIntolerance.
I need to cover these points:
- The frequency of occurrence of the specific symptom. It means that a symptom can be periodic or permanent.
- Where this symptom has occurred. It can occur when a person at work or on the street.
I have not found this information in the specification. So, is it possible (or it's the only opportunity) to cover these points by using custom extensions, because I have not found any official extensions for such cases? Or maybe there is someone who has had such needs and can suggest a possible solution.
Thank you.

Personal guessing if not using extensions:
AllergyIntolerance.reaction.manifestation for (1);
AllergyIntolerance.reaction.description for both (1) and (2);
AllergyIntolerance.reaction.note for (2)
Alternatively, Observations could be used to capture these data and then link it/them to the AllergyIntolerance by Reference (Observation.focus).

The problem is that all these options are codes. I have special codings for the frequency of occurrence of the symptom and for the location. So, I guess, I can not write these values to usual text properties like note or description.
I'll think about Observations. Thank you.

Observation sounds like overkill and they'd probably get lost when passing the allergy around. This might be a situation where extensions are better.

@Lloyd McKenzie Got it. Thanks.
