Vital Signs Quick Start

Quick Start

Below is an overview of the required set of RESTful FHIR interactions - for example, search and read operations - for this profile. See the Conformance requirements for a complete list of supported RESTful interactions for this IG.

  • See the General Guidance 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 using the combination of the patient and category search parameters:

    GET [base]/Observation?patient=[reference]&category=http://terminology.hl7.org/CodeSystem/observation-category|vital-signs

    Example:

    1. GET [base]/Observation?patient=1134281&category=http://terminology.hl7.org/CodeSystem/observation-category|vital-signs

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

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

    GET [base]/Observation?patient=[reference]&code={[system]}|[code]{,{[system]}|[code],...}

    Example:

    1. GET [base]/Observation?patient=1186747&code=http://loinc.org|8867-4,http://loinc.org|9279-1,http://loinc.org|85354-9

    Implementation Notes: Fetches a bundle of all Observation resources for the specified patient and observation code(s). SHOULD support search by multiple codes. The Observation code parameter searches `Observation.code only. (how to search by reference and how to search by token)

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

    GET [base]/Observation?patient=[reference]&category=http://terminology.hl7.org/CodeSystem/observation-category|vital-signs&date={gt|lt|ge|le}[date]{&date={gt|lt|ge|le}[date]&...}

    Example:

    1. GET [base]/Observation?patient=1134281&category=http://terminology.hl7.org/CodeSystem/observation-category|vital-signs&date=ge2019

    Implementation Notes: Fetches a bundle of all Observation resources for the specified patient and date and a category code = vital-signs (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 category and status search parameters:
    • including support for composite OR search on status (e.g.status={[system]}|[code],{[system]}|[code],...)

    GET [base]/Observation?patient=[reference]&category=http://terminology.hl7.org/CodeSystem/observation-category|vital-signs&status={[system]}|[code]{,{[system]}|[code],...}

    Example:

    1. GET [base]/Observation?patient=1134281&category=http://terminology.hl7.org/CodeSystem/observation-category|vital-signs&status=final

    Implementation Notes: Fetches a bundle of all Observation resources for the specified patient and category 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 date search parameters:
    • including optional support for composite OR search on code (e.g.code={[system]}|[code],{[system]}|[code],...)
    • including support for these date comparators: gt,lt,ge,le
    • including optional support for composite AND search on date (e.g.date=[date]&date=[date]]&...)

    GET [base]/Observation?patient=[reference]&code={[system]}|[code]{,{[system]}|[code],...}&date={gt|lt|ge|le}[date]{&date={gt|lt|ge|le}[date]&...}

    Example:

    1. GET [base]/Observation?patient=1186747&code=http://loinc.org|8867-4,http://loinc.org|9279-1,http://loinc.org|85354-9&date=ge2019

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