US Core Implementation Guide
7.0.0-ballot - Ballot United States of America flag

This page is part of the US Core (v7.0.0-ballot: STU7 Ballot 1) based on FHIR (HL7® FHIR® Standard) R4. The current version which supersedes this version is 6.1.0. For a full list of available versions, see the Directory of published versions

US Core SMART Scopes

Page standards status: Informative

This page is new content for US Core Version 7.0.0

To meet the ONC’s granular scope requirement in HTI-1 proposed rule, the US Core API requires servers to support both resource level scopes and granular scopes as defined in Version 2.0.0 of SMART App Launch. US Core clients should follow the principle of least privilege and access only the necessary resources. In other words, if a client needs only vital sign observations, it should request access only to Observations with a category of “vital-signs”. US Core requires scopes for:

  1. specific data types defined in US Core and
  2. those of particular interest to US citizens and health systems.

SMART Scopes

In addition to the read and search capabilities defined in the server’s CapabilityStatement, servers SHALL document supported scopes in the scopes_supported section of a .well-known/smart-configuration capabilities array.

Scopes Format

Version 2.0.0 of SMART App Launch introduced a scope syntax of: <patient|user|system> / <fhir-resource>. <c | r | u | d |s> [?param=value]

For example, to limit read and search access to a specific patient’s laboratory observations but not other observations, the server grants the following scope:

patient/Observation.rs?category=http://terminology.hl7.org/CodeSystem/observation-category|laboratory.

The example scopes below use a single FHIR search parameter of category applied to Condition and Observation. They use a patient/ prefix, but implementers can also support system/ and user/.

  • patient/Condition.rs?category=http://terminology.hl7.org/CodeSystem/condition-category|encounter-diagnosis
  • patient/Condition.rs?category=http://terminology.hl7.org/CodeSystem/condition-category|problem-list-item
  • patient/Condition.rs?category=http://hl7.org/fhir/us/core/CodeSystem/condition-category|health-concern
  • patient/Observation.rs?category=http://terminology.hl7.org/CodeSystem/observation-category|clinical-test
  • patient/Observation.rs?category=http://terminology.hl7.org/CodeSystem/observation-category|laboratory

US Core Server Obligations

The scopes are formally defined in a server hosts a smart-configuration file at [url]/.well-known/smart-configuration that is available to both authenticated and unauthenticated clients.

  • The server SHALL support all scopes listed in the table above for the US Core Profiles they support; additional scopes MAY be supported (so clients should not consider this an exhaustive list).

  • Servers MAY limit clients’ scopes to those configured at registration time. Servers SHALL allow users to select a subset of the requested scopes at the approval time. The app SHOULD inspect the returned scopes and accommodate the differences from the scopes it requested and registered.

Example .well-known/smart-configuration File

This example .well-known/smart-configuration file contains all the US Core scopes listed in the capabilities array. See the SMART App Launch Implementation Guide for more example and details.
