This profile sets minimum expectations for an Observation resource to record, search, and fetch head circumference observations with standard coding and units of measure. It is based on the FHIR Head Circumference 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.
The following are supported usage scenarios for this profile:
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.
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.Usage:

Below is an overview of the mandatory and optional search parameters and combined search parameters. FHIR search operations and the syntax used to describe the interactions is described 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 client SHALL provide at least an id value and MAY provide both the Type and id values. The server 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 client SHALL provide both the system and code values. The server SHALL support both. The client SHOULD support search using IHI, Medicare Number, and DVA Number identifiers as defined in the AU Core Patient profile. The server 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 client SHALL provide at least a code value and MAY provide both the system and code values. The server SHALL support both. The client SHALL support search using the 'vital-signs' category defined in each profile. The server SHALL support search using the 'vital-signs' category defined in each profile. |
code | MAY | token |
The client SHALL provide at least a code value and MAY provide both the system and code values. The server SHALL support both. The client SHALL support search using the LOINC codes defined in each profile. The server SHALL support search using the LOINC codes defined in each profile. |
date | MAY | date |
A client SHALL provide a value precise to the second + time offset. A server SHALL support a value precise to the second + time offset. |
status | MAY | token |
The client SHALL provide at least a code value and MAY provide both the system and code values. The server SHALL support both. |
