Resource Profile: US Core ServiceRequest Profile

Official URL: http://hl7.org/fhir/us/core/StructureDefinition/us-core-servicerequest Version: 5.0.0
Active as of 2022-04-20 Computable Name: USCoreServiceRequestProfile

This profile sets minimum expectations for recording, searching, and fetching using the ServiceRequest resource to promote interoperability and adoption through common implementation. It identifies which core elements, extensions, vocabularies and value sets SHALL be present in the resource when using this profile. It provides the floor for standards development for specific uses cases.

Example Usage Scenarios:

The following are example usage scenarios for the this profile:

  • Query for a specific procedure or test request such as an electrocardiogram (ECG) order or a referral to a support program.
  • Query for a specific service offered to a patient such as a referral to a support program.
  • Query for category of service request (e.g. all cardiology requests)

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 Profile Definition below provides the formal summary, definitions, and terminology requirements.

Each Service Request must have:

  1. a status
  2. an intent code indicating whether the request is a proposal, plan, or order.
  3. a code defining what is being requested
  4. a patient

Each Service Request must support:

  1. a category
  2. when requested service should happen
  3. when request was made
  4. the requester

Profile specific implementation guidance:

  • See the SDOH guidance page for more information when exchanging Social Determinants of Health (SDOH) Service Requests.
  • The ServiceRequest.category binding must support at a minimum the US Core ServiceRequest Category Codes. However, this valueset can be treated as extensible and other category codes can be used instead.
  • The ServiceRequest.code valueset is broad to accommodate a wide variety of use cases and should be constrained to a subset for a particular use case or domain. (for example, LOINC for laboratory orders.)

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.
  • 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 for all servicerequests for a patient using the patient search parameter:

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

    Example:

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

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

  2. SHALL support fetching a ServiceRequest using the _id search parameter:

    GET [base]/ServiceRequest[id]

    Example:

    1. GET [base]/ServiceRequest/1032702
    2. GET [base]/ServiceRequest?_id=1032702

    Implementation Notes: (how to search by the logical id of the resource)

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

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

    Example:

    1. GET [base]/ServiceRequest?patient=f201&category=http://loinc.org|sdoh

    Implementation Notes: Fetches a bundle of all ServiceRequest resources for the specified patient and a category code (how to search by reference and how to search by token)

  4. SHALL support searching using the combination of the patient and code search parameters:
    • including optional support for OR search on code (e.g.code={system|}[code],{system|}[code],...)

    GET [base]/ServiceRequest?patient={Type/}[id]&code={system|}[code]{,{system|}[code],...}

    Example:

    1. GET [base]/ServiceRequest?patient=1032702&code=http://snomed.info/sct|35637008

    Implementation Notes: Fetches a bundle of all ServiceRequest resources for the specified patient and report code(s). SHOULD support search by multiple report codes. (how to search by reference and how to search by token)

  5. SHALL support searching using the combination of the patient and category and authored search parameters:
    • including support for these authored comparators: gt,lt,ge,le
    • including optional support for AND search on authored (e.g.authored=[date]&authored=[date]]&...)

    GET [base]/ServiceRequest?patient={Type/}[id]&category={system|}[code]&authored={gt|lt|ge|le}[date]{&authored={gt|lt|ge|le}[date]&...}

    Example:

    1. GET [base]/ServiceRequest?patient=f201&category=http://loinc.org|sdoh&date=ge2010-01-14T00:00:00Z

    Implementation Notes: Fetches a bundle of all ServiceRequest resources for the specified patient and date and a category code (how to search by reference and how to search by token and how to search by date)

Optional Search Parameters:

The following search parameter combinations SHOULD be supported:

  1. SHOULD support searching using the combination of the patient and status search parameters:
    • including support for OR search on status (e.g.status={system|}[code],{system|}[code],...)

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

    Example:

    1. GET [base]/ServiceRequest?patient=1137192&status=completed

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

  2. SHOULD support searching using the combination of the patient and code and authored search parameters:
    • including optional support for OR search on code (e.g.code={system|}[code],{system|}[code],...)
    • including support for these authored comparators: gt,lt,ge,le
    • including optional support for AND search on authored (e.g.authored=[date]&authored=[date]]&...)

    GET [base]/ServiceRequest?patient={Type/}[id]&code={system|}[code]{,{system|}[code],...}&authored={gt|lt|ge|le}[date]{&authored={gt|lt|ge|le}[date]&...}

    Example:

    1. GET [base]/ServiceRequest?patient=f201&code=http://snomed.info/sct|35637008&date=ge2019-01-14T00:00:00Z

    Implementation Notes: Fetches a bundle of all ServiceRequest resources for the specified patient and date and service code(s). SHOULD support search by multiple report codes. (how to search by reference and how to search by token and how to search by date)
