Verified steps

  1. Identify the US Core profile(s) for the clinical data needed (e.g., Condition, Observation, MedicationRequest) and determine the required search parameters from the current US Core IG.
  2. Authenticate using SMART Backend Services or SMART App Launch depending on whether the query is system-to-system or user-facing, obtaining a token with appropriate scopes (e.g., patient/*.read or system/*.read).
  3. Issue a FHIR search request to the data holder's endpoint using the US Core-specified search parameter combinations, for example GET [base]/Condition?patient=[id]&category=problem-list-item.
  4. Page through the result Bundle using the 'next' link in Bundle.link until no further pages are returned.
  5. Validate that the returned resources conform to the applicable US Core profile, checking must-support elements are present.
  6. Handle the case where the data holder returns an OperationOutcome indicating the query is not supported, and fall back to Task-based exchange if direct query is unavailable.
