US Core Conformance Requirements

This section outlines conformance requirements for the US Core Servers and Client applications, identifying the specific profiles that need to be supported, the specific RESTful operations that need to be supported, and the search parameters that need to be supported. Note: The individual US Core profiles identify the structural constraints, terminology bindings and invariants, however, implementers must refer to the conformance requirements for details on the RESTful operations, specific profiles and the search parameters applicable to each of the US Core actors.

Source Resource: XML/JSON

  1. FHIR Version: 3.0.0
  2. Supported formats: xml, json
  3. Published: 2017-03-08
  4. Published by: Health Level Seven International US Realm Steering Committee

The Section describes the expected capabilities of the US Core Server actor which is responsible for providing responses to the queries submitted by the US Core Requestors. The complete list of FHIR profiles, RESTful operations, and search parameters supported by US Core Servers are defined. Systems implementing this capability statement should meet the ONC 2015 Common Clinical Data Set (CCDS) access requirement for Patient Selection 170.315(g)(7) and Application Access - Data Category Request 170.315(g)(8). US Core Clients have the option of choosing from this list to access necessary data based on their local use cases and other contextual requirements.

Behavior

Description:

The US Core Server SHALL:

  1. Support the US Core Patient resource profile.
  2. Support at least one additional resource profile from the list of US Core Profiles.
  3. Implement the RESTful behavior according to the FHIR specification.
  4. Return the following response classes:
    • (Status 200): successful operation
    • (Status 400): invalid parameter
    • (Status 401/4xx): unauthorized request
    • (Status 403): insufficient scope
    • (Status 404): unknown resource
    • (Status 410): deleted resource.
  5. Support json resource formats for all US Core interactions.
  6. Declare a CapabilityStatement identifying the list of profiles, operations, search parameter supported.

The US Core Server SHOULD:

  1. Support xml resource formats for all US Core interactions.
  2. Identify the US Core profiles supported as part of the FHIR meta.profile attribute for each instance.

Security:

US Core Servers SHALL:

  1. Implement the security requirements documented in the this IG.
  2. A server has ensured that every API request includes a valid Authorization token, supplied via: Authorization: Bearer {server-specific-token-here}
  3. A server has rejected any unauthorized requests by returning an HTTP 401 Unauthorized response code.

Profile Interaction Summary:

  1. All servers SHALL make available the read and search interactions for the Profiles the server chooses to support.
  2. All servers SHOULD make available the vread and history-instance interactions for the Profiles the server chooses to support.
