The US Core Encounter Profile inherits from the FHIR Encounter resource; refer to it for scope and usage definitions. This profile sets minimum expectations for the Encounter resource to record, search, and fetch basic encounter information for an individual patient. It specifies which core elements, extensions, vocabularies, and value sets SHALL be present and constrains how the elements are used. Providing the floor for standards development for specific use cases promotes interoperability and adoption.

Example Usage Scenarios:

The following are example usage scenarios for this profile:

  • Query for a specific patient encounter
  • Query for recent patient encounters
  • Record or update an encounter

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 Encounter Must Have:

  1. A status
  2. A classification such as inpatient, outpatient, or emergency
  3. An encounter type
  4. A patient

Each Encounter Must Support:

  1. A timestamp when the resource last changed*
  2. An encounter identifier
  3. Providers involved in the encounter
  4. When the encounter occurred
  5. Reason for the visit
  6. The discharge disposition
  7. Where the encounter occurred

Profile Specific Implementation Guidance:

  • To search for an encounter diagnosis, query for Condition resources that reference the Encounter of interest and have a category of encounter-diagnosis. An example search is shown in the Condition Quick Start section.
  • The Encounter resource can represent a reason using a code with Encounter.reasonCode or a reference with Encounter.reasonReference to Condition or other resources.
    • Although both are marked as Must Support, servers are not required to support both a code and a reference, but they SHALL support at least one of these elements.
    • The client application SHALL support both elements.
    • If Encounter.reasonReference references an Observation, it SHOULD conform to a US Core Observation if applicable. For example, a laboratory result SHOULD conform to the US Core Laboratory Result Observation Profile.
  • This profile supports where the encounter occurred. The location address can be represented by the Location referenced by Encounter.location.location or indirectly through the Organization referenced by Encounter.serviceProvider.
    • Although both are marked as Must Support, servers are not required to support both Encounter.location.location and Encounter.serviceProvider, but they SHALL support at least one of these elements.
    • The client application SHALL support both elements.
  • The following US Core Profiles indirectly reference the location/facility through references to US Core Encounter:

    If the event facility/location differs from the Encounter.location, systems SHOULD reference it directly:

    • Systems SHALL use the location element for all resources where the element is available.
    • Systems MAY use the standard Event Location Extension for US Core DiagnosticReport Profile for Laboratory Results Reporting and US Core Observation Clinical Result Profile.
  • * See the US Core General Guidance page for Searching Using lastUpdated. Updates to Meta.lastUpdated SHOULD reflect:
    • New encounters/visits
    • Changes in the status of encounters, including events that trigger the same status (e.g., in-progress → in-progress). These status changes correspond to events that can initiate HL7 V2 ADT messages.

Based upon additional testing, we intend to to upgrade the Meta.lastUpdated guidance (SHOULD) to requirements (SHALL) in the next version of US Core

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.

  • See the Scopes Format section for a description of the SMART scopes syntax.
  • See the Search Syntax section for a description of the US Core search syntax.
  • 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.

US Core Scopes

Servers providing access to encounter data SHALL support these US Core SMART Scopes:

Mandatory Search Parameters:

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

  1. SHALL support both read Encounter by id AND Encounter search using the _id search parameter:

    GET [base]/Encounter/[id] or GET [base]/Encounter?_id=[id]

    Example:

    1. GET [base]/Encounter/12354
    2. GET [base]/Encounter?_id=12354

    Implementation Notes: Fetches a single Encounter (how to search by the logical id of the resource)

  2. SHALL support searching for all encounters for a patient using the patient search parameter:

    GET [base]/Encounter?patient={Type/}[id]

    Example:

    1. GET [base]/Encounter?patient=1137192

    Implementation Notes: Fetches a bundle of all Encounter resources for the specified patient (how to search by reference)

  3. SHALL support searching using the combination of the date and patient search parameters:

    • including support for these date comparators: gt,lt,ge,le
    • including optional support for AND search on date (e.g.date=[date]&date=[date]]&...)

    GET [base]/Encounter?date={gt|lt|ge|le}[date]{&date={gt|lt|ge|le}[date]&...}&patient={Type/}[id]

    Example:

    1. GET [base]/Encounter?patient=example1&date=ge2019-01-01T00:00:00Z

    Implementation Notes: Fetches a bundle of all Encounter resources matching the specified date and patient (how to search by date and how to search by reference)

Optional Search Parameters:

The following search parameter combinations SHOULD be supported:

  1. SHOULD support searching for an encounter by an identifier using the identifier search parameter:

    GET [base]/Encounter?identifier={system|}[code]

    Example:

    1. GET [base]/Encounter?identifier=http://hospital.smarthealthit.org|1032702

    Implementation Notes: Fetches a bundle containing any Encounter resources matching the identifier (how to search by token)

  2. SHOULD support searching using the combination of the class and patient search parameters:

    GET [base]/Encounter?class={system|}[code]&patient={Type/}[id]

    Example:

    1. GET [base]/Encounter?patient=example1&class= http://terminology.hl7.org/CodeSystem/v3-ActCode code|AMB

    Implementation Notes: Fetches a bundle of all Encounter resources matching the specified class and patient (how to search by reference and how to search by token)

  3. SHOULD support searching using the combination of the patient and type search parameters:

    GET [base]/Encounter?patient={Type/}[id]&type={system|}[code]

    Example:

    1. GET [base]/Encounter?patient=1137192&type=http://www.ama-assn.org/go/cpt code|99211

    Implementation Notes: Fetches a bundle of all Encounter resources matching the specified patient and type (how to search by reference and how to search by token)

  4. SHOULD support searching using the combination of the patient and location search parameters:

    GET [base]/Encounter?patient={Type/}[id]&location={Type/}[id]

    Example:

    1. GET [base]/Encounter?patient=1137192&location=Location/hospital

    Implementation Notes: Fetches a bundle of all Encounter resources matching the specified patient and location (how to search by reference)

  5. SHOULD support searching using the combination of the patient and status search parameters:

    GET [base]/Encounter?patient={Type/}[id]&status={system|}[code]

    Example:

    1. GET [base]/Encounter?patient=example1&status=finished

    Implementation Notes: Fetches a bundle of all Encounter resources matching the specified patient and status (how to search by reference and how to search by token)

  6. SHOULD support searching using the combination of the patient and discharge-disposition search parameters:

    GET [base]/Encounter?patient={Type/}[id]&discharge-disposition={system|}[code]

    Example:

    1. GET [base]/Encounter?patient=example1&discharge-disposition=01

    Implementation Notes: Fetches a bundle of all Encounter resources matching the specified patient and discharge-disposition (how to search by reference and how to search by token)

  7. SHOULD support searching using the combination of the patient and _lastUpdated search parameters:

    • including support for these _lastUpdated comparators: gt,lt,ge,le
    • including optional support for AND search on _lastUpdated (e.g._lastUpdated=[date]&_lastUpdated=[date]]&...)

    GET [base]/Encounter?patient={Type/}[id]&_lastUpdated={gt|lt|ge|le}[date]{&_lastUpdated={gt|lt|ge|le}[date]&...}

    Example:

    1. GET [base]/Encounter?patient=1137192&_lastUpdated=ge2024-01-01T00:00:00Z

    Implementation Notes: Fetches a bundle of all Encounter resources for the specified patient and _lastUpdated. See the US Core General Guidance page for Searching Using lastUpdated. (how to search by reference and how to search by date)
