AU Core Implementation Guide, published by HL7 Australia. This guide is not an authorized publication; it is the continuous build for version 1.0.0-ci-build built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/hl7au/au-fhir-core/ and changes regularly. See the Directory of published versions

Resource Profile: AU Core Body Height

This profile sets minimum expectations for an Observation resource to record, search, and fetch body height observations with standard coding and units of measure. It is based on the FHIR Body Height Profile and identifies the additional mandatory core elements, extensions, vocabularies and value sets that SHALL be present in the Observation resource when conforming to this profile. It provides the floor for standards development for specific uses cases in an Australian context.

See Comparison with other national and international IGs for a comparison between AU Core profiles and profiles in other implementation guides.

Usage scenarios

The following are supported usage scenarios for this profile:

  • Query for observations of body height associated with a patient
  • Record or update an observation of body height associated with a patient

Profile specific implementation guidance

  • Observation.category provides an efficient way of supporting system interactions, e.g. restricting searches. Implementers need to understand that data categorisation is somewhat subjective. The categorisation applied by the source may not align with a receiver’s expectations.
  • Observations MAY have additional codes that translate or map to the Observation code or category codes. For example:
    • providing a local code
    • providing a more specific codes such as 8306-3 - Body height - lying in addition to 8302-2 - Body height. Several additional observation codes are provided in the FHIR core specification vital signs table.
  • Observations MAY have [component] observations to qualify the vital sign observation. For example, 8478-0 - Mean blood pressure, 8887-2 - Heart rate device type, 8326-1 - Type of body temperature device. Several of these are provided in the FHIR core specification vital signs table.

    The requester SHALL support these search comparators gt, lt, ge, le. The responder SHALL support these search comparators gt, lt, ge, le.

    The requester SHOULD support multipleAnd, and if multipleAnd is supported, SHALL support the search comparators gt, lt, ge, le. The responder SHOULD support multipleAnd, and if multipleAnd is supported, SHALL support the search comparators gt, lt, ge, le.
    status MAY token The requester SHALL provide at least a code value and MAY provide both the system and code values. The responder SHALL support both.

    The requester SHALL support multipleOr.The responder SHALL support multipleOr.

    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:
      • SHOULD support chained searching of patient canonical identifier patient.identifier (e.g. patient.identifier=[system|][code])

      GET [base]/Observation?patient={Type/}[id]&category=vital-signs

      Example:

      1. GET [base]/Observation?patient=5678&category=vital-signs

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

    2. SHALL support searching using the combination of the patient and category and date search parameters:
      • SHOULD support chained searching of patient canonical identifier patient.identifier (e.g. patient.identifier=[system|][code])
      • SHALL support these date comparators: gt,lt,ge,le
      • SHOULD support multipleAnd search on date (e.g.date=[date]&date=[date]]&...), and if multipleAnd is supported, SHALL support the search comparators gt,lt,ge,le

      GET [base]/Observation?patient={Type/}[id]&category=vital-signs&date={gt|lt|ge|le}[date]{&date={gt|lt|ge|le}[date]&...}

      Example:

      1. GET [base]/Observation?patient=5678&category=vital-signs&date=ge2020-01-01T00:00:00Z

      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)

    3. SHALL support searching using the combination of the patient and code search parameters:
      • SHOULD support chained searching of patient canonical identifier patient.identifier (e.g. patient.identifier=[system|][code])
      • SHOULD support multipleOr search on code (e.g.code={system|}[code],{system|}[code],...)

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

      Example:

      1. GET [base]/Observation?patient=5678&code=http://snomed.info/sct|364075005,http://loinc.org|8302-2,http://loinc.org|85354-9

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

    Optional Search Parameters:

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

    1. SHOULD support chained searching of patient canonical identifier patient.identifier (e.g. patient.identifier=[system|][code])

      GET [base]/Observation?patient.identifier=[system|][code]

      Example:

      1. GET [base]/Observation?patient.identifier=http://ns.electronichealth.net.au/id/medicare-number|32788511952
      2. GET [base]/Observation?patient.identifier=http://ns.electronichealth.net.au/id/hi/ihi/1.0|8003608833357361

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

    2. SHOULD support searching using the combination of the patient and category and status search parameters:
      • SHOULD support chained searching of patient canonical identifier patient.identifier (e.g. patient.identifier=[system|][code])
      • SHALL support multipleOr search on status (e.g.status={system|}[code],{system|}[code],...)

      GET [base]/Observation?patient={Type/}[id]&category=vital-signs&status={system|}[code]{,{system|}[code],...}

      Example:

      1. GET [base]/Observation?patient=5678&category=vital-signs&status=final
      2. GET [base]/Observation?patient=5678&category=vital-signs&status=final,preliminary

      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)

    3. SHOULD support searching using the combination of the patient and code and date search parameters:
      • SHOULD support chained searching of patient canonical identifier patient.identifier (e.g. patient.identifier=[system|][code]
      • SHOULD support multipleOr search on code (e.g.code={system|}[code],{system|}[code],...)
      • SHALL support these date comparators: gt,lt,ge,le
