This profile sets minimum expectations for an Observation resource to record, search, and fetch blood pressure observations with standard coding and units of measure. It is based on the FHIR Blood Pressure 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.

Usage scenarios

The following are supported usage scenarios for this profile:

  • Query for observations of blood pressure associated with a patient
  • Record or update an observation of blood pressure associated with 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.
  • 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.

  • Because blood pressure values are communicated in the mandatory systolic and diastolic components:
    • Observation.value[x] element SHOULD be omitted
    • an Observation without a systolic or diastolic result value, SHOULD include a reason why the data is absent in Observation.component.dataAbsentReason

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. The requester SHALL support search using the 'vital-signs' category defined in each profile. The responder SHALL support search using the 'vital-signs' category defined in each 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 each profile. The responder SHALL support search using the LOINC codes defined in each profile.
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=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)

  3. 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=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)

  4. 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|85354-9,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 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&

    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]&...}
