This page addresses how sex and gender related concepts can be structured in FHIR and conformant to AU eRequesting.

AU eRequesting references AU Base and AU Core profiles which represent sex and gender concepts. AU Cores places *Must Support* on some concepts and inherits sex and gender related elements localised in AU Base, which has considered the logical data element models provided by [HL7 International’s Cross Paradigm Implementation Guide: Gender Harmony - Sex and Gender Representation, Edition 1 specification](https://hl7.org/xprod/ig/uv/gender-harmony/informative1/).

The table below provides an overview of the sex and gender concepts that are included in AU eRequesting through reference to AU Core and AU Base.

**Legend:**

<img src="green_checkmark.png" width="20"/> **Supported**: The sex or gender related concept is marked as *Must Support*.

<img src="orange_checkmark.png" width="20"/> **Localised**: The sex or gender related concept is localised for use in an Australian context but is not marked as *Must Support*.

<img src="minus_symbol.png" width="20"/> **Not localised**: The sex or gender related concept is not localised for use in an Australian context.

### Administrative Gender (Patient.gender)
By reference to AU Core Patient, AU eRequesting supports the exchange of Administrative Gender, i.e. the basic `Patient.gender` property, as a *Must Support* element in [AU Core Patient](https://build.fhir.org/ig/hl7au/au-fhir-core/StructureDefinition-au-core-patient.html). As per AU Base, the `Patient.gender` value **SHALL** be regarded as a Recorded Sex or Gender. AU Core adopts without change, the implementation guidance defined in the [Administrative Gender (Patient.gender)](https://build.fhir.org/ig/hl7au/au-fhir-base/sexgender.html#administrative-gender-patientgender) section of the AU Base [Sex and Gender](https://build.fhir.org/ig/hl7au/au-fhir-base/sexgender.html) page.

### Name to Use
By reference to AU Core Patient, AU eRequesting supports the exchange of the Name to Use data element (as defined in the [HL7 Cross Paradigm Implementation Guide: Gender Harmony - Sex and Gender Representation, Edition 1](https://hl7.org/xprod/ig/uv/gender-harmony/informative1/)), and `name.use` is a *Must Support* element in [AU Core Patient](https://build.fhir.org/ig/hl7au/au-fhir-core/StructureDefinition-au-core-patient.html). It is important to note that, `name.period` is not a *Must Support* element. AU Core adopts without change, the implementation guidance defined in the [Name to Use](https://build.fhir.org/ig/hl7au/au-fhir-base/sexgender.html#name-to-use-ntu) section of the AU Base [Sex and Gender](https://build.fhir.org/ig/hl7au/au-fhir-base/sexgender.html) page.

### Pronouns​
By reference to AU Core Patient, AU eRequesting supports the exchange of the Pronouns data element (as defined in the [HL7 Cross Paradigm Implementation Guide: Gender Harmony - Sex and Gender Representation, Edition 1](https://hl7.org/xprod/ig/uv/gender-harmony/informative1/)). The [Individual Pronouns](https://build.fhir.org/ig/HL7/fhir-extensions//StructureDefinition-individual-pronouns.html) extension is a *Must Support* element in [AU Core Patient](https://build.fhir.org/ig/hl7au/au-fhir-core/StructureDefinition-au-core-patient.html), with the value element of the extension constrained to be [Australian Pronouns](https://www.healthterminologies.gov.au/integration/R4/fhir/ValueSet/australian-pronouns-1) ([extensible](http://hl7.org/fhir/R4/terminologies.html#extensible)). AU Core adopts without change, the implementation guidance defined in the [Pronouns](https://build.fhir.org/ig/hl7au/au-fhir-base/sexgender.html#pronouns) section of the AU Base [Sex and Gender](https://build.fhir.org/ig/hl7au/au-fhir-base/sexgender.html) page.

### Gender Identity
By reference to AU Core Patient, AU eRequesting supports the exchange of the Gender Identity data element (as defined in the [HL7 Cross Paradigm Implementation Guide: Gender Harmony - Sex and Gender Representation, Edition 1](https://hl7.org/xprod/ig/uv/gender-harmony/informative1/)).  The [Individual Gender Identity](https://build.fhir.org/ig/HL7/fhir-extensions//StructureDefinition-individual-genderIdentity.html) extension is a *Must Support* element in [AU Core Patient](https://build.fhir.org/ig/hl7au/au-fhir-core/StructureDefinition-au-core-patient.html), with the value element of the extension constrained to be [Gender Identity Response](https://healthterminologies.gov.au/fhir/ValueSet/gender-identity-response-1) ([extensible](http://hl7.org/fhir/R4/terminologies.html#extensible)). AU Core adopts without change, the implementation guidance defined in the [Gender Identity](https://build.fhir.org/ig/hl7au/au-fhir-base/sexgender.html#gender-identity-gi) section of the AU Base [Sex and Gender](https://build.fhir.org/ig/hl7au/au-fhir-base/sexgender.html) page.

### Sex Assigned at Birth
In AU Core, Sex Assigned at Birth is profiled as [AU Core Sex Assigned At Birth](https://build.fhir.org/ig/hl7au/au-fhir-core/StructureDefinition-au-core-rsg-sexassignedab.html). While elements within AU Core Sex Assigned at Birth are *Must Support*, usage of the profile is not *Must Support* in [AU Core Patient](https://build.fhir.org/ig/hl7au/au-fhir-core/StructureDefinition-au-core-patient.html) which is referenced by AU eRequesting. That profile provides an implementation of the guidance in the [Sex Assigned at Birth](https://build.fhir.org/ig/hl7au/au-fhir-base/sexgender.html#sex-assigned-at-birth) section of the AU Base [Sex and Gender](https://build.fhir.org/ig/hl7au/au-fhir-base/sexgender.html) page.
