Resource Profile: AU Core Diagnostic Result Observation

Official URL: http://hl7.org.au/fhir/core/StructureDefinition/au-core-diagnosticresult Version: 0.4.1-preview
Standards status: Draft Maturity Level: 1 Computable Name: AUCoreDiagnosticResult

This profile sets minimum expectations for an Observation resource to record, search, and fetch diagnostic results associated with a patient. It is based on the AU Base Diagnostic Result profile and identifies the additional mandatory core elements, extensions, vocabularies and value sets that SHALL be present in the Observation when conforming to this profile. It provides the floor for standards development for specific uses cases in an Australian context.

Usage scenarios

The following are supported usage scenarios for this profile:

  • Query for diagnostic results for a patient
  • Query for category of diagnostic results (e.g. all cardiology results)
  • Record or update a diagnostic result for a patient

Comparison with other national and international IGs

A resource conforming to this profile is conformant to:

Conformance in reverse is not guaranteed, i.e. a resource conforming to International Patient Access, International Patient Summary, or US Core MAY NOT conform to AU Core.

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.
  • The 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 code
  • The use of coding can vary significantly across systems, requesters need to understand that they may encounter codes they do not recognise and be prepared to handle those resources appropriately. Responders SHOULD populate Observation.code.text and/or Observation.code.coding.display so that the requester can at least display the observation even if the requester does not recognise the code supplied.
  • The Observation resource can represent a result using a single value in Observation.value, or can represent a set of results using either Observation.component.value or Observation.hasMember.
    • Although all are marked as Must Support, responders are not required to support all choices, but they SHALL support at least one of these elements
    • A requester SHALL support all elements (Observation.value, Observation.component.value, Observation.hasMember)
  • Observation.identifier may contain the same identifier as in the order or report connecting the resources that are related to a single request fulfilment workflow
  • Source system identifiers that identify the business process (order ids and reporting identifiers) MAY be included as AU Local Order Identifier and AU Local Report Identifier to support workflow and deduplication of Observation resources.
    • See guidance on the construction of an identifier on the relevant Identifier profile page and the section on Business Identifiers in AU Base.

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 SHALL reference The requester SHALL provide at least an id value and MAY provide both the Type and id values. The responder SHALL support both.
patient+category SHALL reference+token
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.
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.
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.
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.
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.

Mandatory Search Parameters:

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

  1. SHALL support searching using the patient search parameter:
    • SHOULD support chained searching of patient canonical identifier patient.identifier (e.g. patient.identifier=[system|][code])

    GET [base]/Observation?patient={Type/}[id] or optionally GET [base]/Observation?patient.identifier=[system|][code]

    Example:

    1. GET [base]/Observation?patient=5678
    2. GET [base]/Observation?patient.identifier=http://ns.electronichealth.net.au/id/medicare-number|32788511952
    3. 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. 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|survey

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

  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|89240007,http://loinc.org|14683-7,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)

  4. 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|survey&date=ge2020-01-01T00:00:00Z

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

Optional Search Parameters:

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

  1. 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|survey&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:
    • 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|89240007,http://loinc.org|14683-7,http://loinc.org|85354-9&date=ge2020-01-01T00:00:00Z
