Requirements for the Provider FHIR Server participating in USCDI+ CTM. This CapabilityStatement primarily applies to Sponsor-initiated Trial Matching, where the Provider FHIR Server acts as the FHIR RESTful server and responds to requests initiated by the CTM Matching Service. In Provider-initiated Trial Matching, the Provider System acts as the CDS Hooks client and may use the Provider FHIR Server internally to prepare CTM-relevant input data; that CDS Hooks-based behavior is described elsewhere in this guide and is not fully represented by this CapabilityStatement.
| Mode | Server |
|---|---|
| Documentation | Sponsor-initiated Trial Matching: the Provider FHIR Server acts as the FHIR RESTful server. It responds to authorized patient-level read and search requests from the CTM Matching Service and returns the baseline USCDI+ CTM resource types needed for matching. Provider-initiated Trial Matching: the Provider System acts as the CDS Hooks client, initiates the CDS Hooks interaction, and may use the Provider FHIR Server internally to assemble CTM-relevant input data before calling the CTM service. That workflow is referenced here for context but is specified elsewhere in the guide. |
| Description | For Sponsor-initiated Trial Matching, the Provider FHIR Server is responsible for enforcing the deployment's approved authorization and access-control requirements for FHIR read and search interactions. For Provider-initiated Trial Matching, any internal use of the Provider FHIR Server to prepare CTM-relevant input data is governed by the provider organization's local security architecture. Optional external follow-up retrieval by the CTM service requires explicit authorization support from the Provider System and is not required for all deployments. |
