Topic: IG QA Invariant warning on claim.careTeam.sequence

Hi - Using sushi 2.2.3, FHIR v4.0.1.
Added invariant rule on Claim profile as expression "careTeam.sequence = item.careTeamSequence".
Example instance includes (code snippet):

* careTeam.sequence  = 1
* careTeam.provider  = Reference(DrKelly)
      .....

* item.sequence                     = 1

* item.careTeamSequence = 1
.....
QA error is:

Any ideas why the QA warning occurs?

Presuming that you're declaring this at the base of Claim, what you'll get is two collections = the full set of careTeam.sequences and the full set of item.careTeamSequence values. If the two collections aren't identical, the warning will fire.

Lloyd McKenzie (Jan 11 2022 at 21:21):

What are you trying to actually enforce? That the item.careTeamSequence is one of the defined careTeam.sequence values?

Lloyd McKenzie (Jan 11 2022 at 21:22):

If so, then your context should be in item.careTeamSequence and it should be %resource.careTeam[sequence=$this].exists() - I think :)
