Any FHIR capability may be 'allowed' by the system unless explicitly marked as 'SHALL NOT'. A few items are marked as MAY in the Implementation Guide to highlight their potential relevance to the use case.

SHALL Support the Following Implementation Guides

FHIR RESTful Capabilities

Mode: server

A conformant Oncology CRD Service SHALL:

  1. Be capable of evaluating the selected anti-cancer regimen RequestGroup and optionally resolving its instantiated PlanDefinition.
  2. Evaluate patient-specific treatment-intent and line-of-therapy slices carried with the Da Vinci CRD ext-request-category URL on the RequestGroup. Use fhirAuthorization — when provided in the CDS Hooks request — to query the EHR FHIR server for additional required oncology patient context (cancer condition, staging, biomarkers, performance status, and prior therapy).
  3. Return informational cards at order-select indicating the approvability status of the ordered regimen. These cards are advisory — the order has not been committed.
  4. Return a final determination at order-sign with the appropriate indicator: success for Authorization Satisfied, warning for PA-required or DTR-required.
  5. Surface biosimilar substitution requirements at order-select so the provider is informed of payer modifications before signing.
  6. Return a DTR launch card when required context is not available from the EHR FHIR server.

  • The required, recommended, and some optional search parameters (if any).
  • The linked resources enabled for _include
  • The other resources enabled for _revinclude
