US Core Implementation Guide
6.1.0 - STU6 United States of America flag

This page is part of the US Core (v6.1.0: STU6 Update) based on FHIR R4. This is the current published version. For a full list of available versions, see the Directory of published versions. Page versions: STU6.1 STU6 STU5 STU4 STU3 STU2

Resource Profile: US Core PractitionerRole Profile

Active as of 2022-04-20 Computable Name: USCorePractitionerRoleProfile

This profile sets minimum expectations for the PractitionerRole Resource to record, search, and fetch the practitioner role for a practitioner to promote interoperability and adoption through common implementation. It identifies which core elements, extensions, vocabularies, and value sets SHALL be present and constrains the way the elements are used and constrains the way the elements are used when using the profile. It provides the floor for standards development for specific use cases. The requirements for the US Core Practitioner were drawn from the Argonaut Provider Directory, IHE Healthcare Provider Directory and the ONC Provider Directory Workshop.

Mandatory and Must Support Data Elements

The following data-elements must always be present (Mandatory definition) or must be supported if the data is present in the sending system (Must Support definition). They are presented below in a simple human-readable explanation. Profile specific guidance and examples are provided as well. The Formal Views below provides the formal summary, definitions, and terminology requirements.

Each PractitionerRole Must Support:

  1. An associated organization
  2. An associated practitioner
  3. A role
  4. A specialty
  5. An associated location
  6. Contact information
  7. A communication endpoint

Profile Specific Implementation Guidance:

  • At least one of the following elements must be present:
    • PractitionerRole.practitioner
    • PractitionerRole.organization
    • PractitionerRole.healthcareService
    • PractitionerRole.location
  • As a result of implementation feedback, the US Core Location and PractitionerRole Profiles are not explicitly referenced in any US Core Profile. However they SHOULD be used as the default profile if referenced by another US Core profile. See this guidance on Referencing US Core Profiles.
  • A Direct address can be represented in the telecom element using the US Core Direct email Extension or in a referenced Endpoint as a “direct-project” endpoint connection type.
  • When selecting role codes, implementers SHOULD choose the code that reflects the specific duties performed within that role rather than the specialty unless the individual’s professional specialization characterizes the role.
  • Clients can request servers return the Practitioner resource and Endpoint resources by using _include. See Quick Start.

Notes:


Quick Start


Below is an overview of the required Server RESTful FHIR interactions for this profile - for example, search and read operations - when supporting the US Core interactions to access this profile’s information (Profile Support + Interaction Support). Note that systems that support only US Core Profiles (Profile Only Support) are not required to support these interactions. See the US Core Server CapabilityStatement for a complete list of supported RESTful interactions for this IG.

  • The syntax used to describe the interactions is described here.

  • Servers providing access to practitioner role data can use US Core SMART Scopes for:
  • See the General Requirements section for additional rules and expectations when a server requires status parameters.
  • See the General Guidance section for additional guidance on searching for multiple patients.

Mandatory Search Parameters:

The following search parameters and search parameter combinations SHALL be supported:

  1. SHALL support searching practitioner role by specialty using the specialty search parameter:

    • including optional support for these _include parameters: PractitionerRole:endpoint,PractitionerRole:practitioner

    GET [base]/PractitionerRole?specialty={system|}[code]

    Example:

    1. GET [base]/PractitionerRole?specialty=http://nucc.org/provider-taxonomy|208D0000X

    Implementation Notes: Fetches a bundle containing PractitionerRole resources matching the specialty (how to search by token)

  2. SHALL support searching practitioner role by practitioner name and identifier using chained parameters using the practitioner search parameter:

    • including support for these chained parameters: practitioner.identifier,practitioner.name
    • including optional support for these _include parameters: PractitionerRole:endpoint,PractitionerRole:practitioner

    GET [base]/PractitionerRole?practitioner={Type/}[id]

    Example:

    1. GET [base]/PractitionerRole?practitioner.identifier=http://hl7.org/fhir/sid/us-npi|97860456&_include=PractitionerRole:practitioner&_include=PractitionerRole?endpoint
    2. GET [base]/PractitionerRole?practitioner.name=Henry&_include=PractitionerRole:practitioner&_include=PractitionerRole?endpoint

    Implementation Notes: Fetches a bundle containing PractitionerRole resources matching the chained parameter practitioner.name or practitioner.identifier.SHOULD support the _include for PractionerRole.practitioner and PractitionerRole.endpoint. (how to search by reference)
