AU Core Implementation Guide
1.0.0-ci-build - CI Build Australia flag

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 Smoking Status

This profile sets minimum expectations for an Observation resource to record, search, and fetch observations that represent a patient’s smoking status, i.e. current behaviour for all types of tobacco smoking, with standard coding. It is based on the core FHIR Observation resource 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 smoking status associated with a patient
  • Record or update an observation of smoking status 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.
  • Additional codes that translate or map to the Observation code or category codes are allowed. For example providing both a local code and the required code.

Usage:

Changes since version 1.0.0-ballot:

  • No changes

    Notes:

    Below is an overview of the mandatory and optional search parameters and combined search parameters. See the AU Core CapabilityStatements for a complete list of supported RESTful interactions for this IG.

    FHIR search operations are described here and the syntax used to describe AU Core interactions is defined here.

    Any search parameter defined in FHIR may be ‘allowed’ by the system unless explicitly marked as “SHALL NOT”. A few items are marked as MAY in this implementation guide to highlight their potential relevance.

    Parameter(s) Conformance Type(s) Requirements (when used alone or in combination)

    patient+category+date SHALL reference+token+date
    patient+code SHALL reference+token
    patient+category+status SHOULD reference+token+token
    patient+code+date SHOULD reference+token+date
    patient.identifier SHOULD reference.token The requester SHALL provide both the system and code values. The responder SHALL support both.

    The requester SHOULD support search using IHI, Medicare Number, and DVA Number identifiers as defined in the AU Core Patient profile. The responder SHOULD support search using the using IHI, Medicare Number, and DVA Number identifiers as defined in the AU Core Patient profile.
    patient MAY reference The requester SHALL provide at least an id value and MAY provide both the Type and id values. The responder SHALL support both.
    category 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 search using the category code defined in this profile. The responder SHALL support search using the category code defined in this profile.
    code 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 search using the LOINC codes defined in this profile. The responder SHALL support search using the LOINC codes defined in this profile.

    The requester SHALL support multipleOr. The responder SHALL support multipleOr.
    date MAY date A requester SHALL provide a value precise to the second + time offset. A responder SHALL support a value precise to the second + time offset.

    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={system|}[code]

      Example:

      1. GET [base]/Observation?patient=5678&category=http://terminology.hl7.org/CodeSystem/observation-category|social-history
      2. GET [base]/Observation?patient.identifier=http://ns.electronichealth.net.au/id/hi/ihi/1.0|8003608833357361&category=http://terminology.hl7.org/CodeSystem/observation-category|social-history

      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]]&...)

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

      Example:

      1. GET [base]/Observation?patient=5678&category=http://terminology.hl7.org/CodeSystem/observation-category|social-history&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 = social-history (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|266918002

      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={system|}[code]&status={system|}[code]{,{system|}[code],...}

      Example:

      1. GET [base]/Observation?patient=5678&category=http://terminology.hl7.org/CodeSystem/observation-category|social-history&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)

    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
      • SHOULD support multipleAnd search on date (e.g.date=[date]&date=[date]]&...)

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

      Example:

      1. GET [base]/Observation?patient=5678&code=http://snomed.info/sct|266918002&date=ge2020-01-01T00:00:00Z
      2. GET [base]/Observation?patient.identifier=http://example.org/fhir/mrn|12345&code=http://snomed.info/sct|266918002&date=ge2020-01-01T00:00:00Z

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