We are reviewing the e-RS FHIR API specification and migration documentation, and it is not clear when a referral shortlist can no longer be changed.
Could you clarify whether A031 Change Shortlist is permitted once a referral:
- has resulted in a booked appointment,
- has been deferred to a provider service, or
- has been sent for triage during referral creation?
The documentation appears to position A031 Change Shortlist before A016 Book or Defer Appointment, but it does not explicitly state whether shortlist changes are still valid after any of the above events have occurred.
We also reviewed A029 Available Actions for User, as this seemed the most likely source for determining whether “Change Shortlist” is permitted. However, we couldn’t find anything in the specification that clearly defines whether the Change Shortlist action should or should not be available when a referral is booked, deferred, or awaiting triage.
Could you therefore confirm:
- The expected business rules for shortlist changes in the above scenarios.
- Whether A029 Available Actions for User should be treated as the authoritative mechanism for determining if A031 Change Shortlist is available for a referral in its current state.
