# Health Connect Australia Provider Directory FHIR Implementation Guide

26.0.0 - Trial

Health Connect Australia Provider Directory FHIR Implementation Guide, published by Australian Digital Health Agency. This guide is not an authorized publication; it is the continuous build for version 26.0.0 built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/AuDigitalHealth/HCPD/ and changes regularly. See the Directory of published versions

## Resource Profile: HCPD Endpoint

This profile defines a Health Connect Provider Directory entry for a technical endpoint.

No data is entered directly into Health Connect; all Directory content is sourced from authoritative systems including PCA, HI-Service, and NHSD.

#### Extensions

Extensions introduced in this profile:

- Endpoint: AU Receiving Facility
- Endpoint: AU Receiving Application
- Endpoint: Encryption Certificate PEM X509

### Usage notes

The following guidance expands on operational and implementation expectations for this Endpoint profile.

- Purpose: An `Endpoint` in Health Connect describes how to communicate with a service (address, protocol, payloads and contact details). Directory consumers use this information to establish connections, and operational tooling uses it to monitor and validate connectivity.

#### Guidance on the use of endpoints

The HCPD IG offers flexibility with the use of endpoints. The IG supports referencing an endpoint from the HealthcareService, Location & PractitionerRole resources. The recommended hierarchy for when endpoints SHOULD be applied is as follows:

- When a HealthcareService, with it's associated referenced Location and PractitionerRoles exist within the same space then an endpoint at this level is suggested.

- When a Location requires differentiation from the referenced HealthcareService due to operational or business requirements, then referencing an endpoint at this level may make sense for the particular use case.

- If a high degree of granular communication is required then referencing an endpoint from the PractitionerRole resource could be applicable.

#### Implementation requirements vs. processing

Implementers SHALL process all elements marked as Must Support (MS) in this profile to be conformant. However, certain elements that are mandatory do not need to be processed by Health Connect Provider Directory Requester Actors:

- Endpoint.status: This element is not MUST SUPPORT but is mandatory therefore it MAY be ignored by implementing systems. A value will be provided but MAY be ignored.

#### Initial endpoint scope and future expansion

Health Connect initially expects published `Endpoint` resources to describe Secure Messaging endpoints (SMD-capable targets and related secure messaging transports). Requesters and search clients should expect SMD-specific metadata and prioritise handling SMD attributes (SMD Target Identifier, encryption certificate, and routing identifiers). Over time, clients may be able to handle additional protocol metadata (for example, FHIR REST endpoint details) as publishers begin to expose FHIR and other transport types.

#### Identifiers and stable handles

The Endpoint profile uses two stable identifier slices for Directory management and routing:

- HCPD Local Identifier (HCPD-LI) - Unique identifier attributed by the HCPD system.

- HCPD SMD Target Identifier - a slice used only when the endpoint (or associated practitioner/service) supports Secure Messaging Delivery (SMD). When present the SMD identifier SHALL be globally unique and SHALL be treated as an immutable routing handle for secure point‑to‑point or hub‑mediated messaging. Publishers SHOULD only populate this slice for endpoints that actually support SMD.

### Reciprocal relationships

In FHIR, linkage to resources is owned by the referencing resources (`HealthcareService.endpoint`, `PractitionerRole.endpoint`, `Location.endpoint`). The Endpoint resource itself has no back‑reference slots to those resources. Consequently:

- Reciprocity cannot be enforced within the Endpoint profile (there is no standard element on Endpoint to list referencing HealthcareService / Location / PractitionerRole resources).
- Directory governance MUST ensure that when a referencing resource adds or removes an Endpoint, any operational expectations (availability, deprecation, auditing) are handled in process.

Usages:

- Refer to this Profile: HCPD HealthcareService, HCPD Location, HCPD PractitionerRole and HCPD Provenance

Slices

This structure defines the following Slices:

- The element 2 is sliced based on the values of Endpoint.identifier

Other representations of profile: CSV, Excel, Schematron

### Notes:

### Search parameters

This IG defines and introduces several search parameters in addition to those inherited from R4, that make it easier to find and filter `HCPD Endpoint` resources in Health Connect implementations.

#### Search parameters defined in this IG

The following search parameters are defined by this IG and SHOULD be supported:

- `hcepi` (Endpoint.identifier where type = Resource Identifier)
  - Find endpoint records by the HCPD identifier assigned in Health Connect. Uses token matching for exact value matching.
  - Example: `GET /Endpoint?hcepi=EP001234567890`
- `payloadmimetype` (Endpoint.payloadMimeType)
  - Search for endpoints that advertise support for a specific MIME type for payloads.
- Typical values present in this IG's example data are:
  - `application/pdf`
  - `application/fhir+xml`
  - `application/fhir+json`
  - Example: `GET /Endpoint?payloadmimetype=application%2Ffhir%2Bjson`
- `epurl` (alias used in this IG for Endpoint.address)
  - Convenience alias used in this IG's documentation to search by endpoint address.
  - Example: `GET /Endpoint?epurl=https://smd.sydneyhospital.org.au/secure-messaging/endpoint`

#### Search parameters from R4

The following search parameters are inherited from FHIR R4 and have been deemed useful for implementation within this IG. They SHOULD be supported:

- `name (R4)` (Endpoint.name)
  - Search for endpoints by name (partial matches may be supported).
  - Example: `GET /Endpoint?name=My%20GP%20Service`
- `connection-type (R4)` (Endpoint.connectionType)
  - Search for endpoints by connection type (for example, `hl7-fhir-rest` or other interface codes).
  - Example: `GET /Endpoint?connection-type=http://terminology.hl7.org.au/CodeSystem/endpoint-connection-type|secure-messaging`
- `payload-type (R4)` (Endpoint.payloadType)
  - Search for endpoints by payload type (CodeableConcept). Use AU PD Endpoint payload type ValueSet codes where applicable.
  - Example: `GET /Endpoint?payload-type=http://hl7.org.au/fhir/pd/CodeSystem/endpoint-payload-type|some-payload`

Note: Support for _id is mandatory for a responder and optional for a requester. Where the expectation for a search parameter differs between actors, the table below will reflect the stronger conformance requirement.

Parameter(s) | Conformance | Type(s) | Requirements (when used alone or in combination)
--- | --- | --- | ---
_id | SHOULD | `token` |
hcepi | SHOULD | `token` |
name (R4) | SHOULD | `string` |
connection-type (R4) | SHOULD | `token` |
payload-type (R4) | SHOULD | `token` |
epurl | SHOULD | `uri` |
payloadmimetype | SHOULD | `token` |
name+connection-type | SHOULD | `string`+`token` |
name+payload-type | SHOULD | `string`+`token` |
connection-type+payloadmimetype | SHOULD | `token`+`token` |

### Search reverse include parameters

This implementation supports the following `_revinclude` parameters when searching for Endpoint resources:

- `_revinclude=HealthcareService:endpoint` - Include HealthcareService resources that reference this Endpoint
- `_revinclude=Location:endpoint` - Include Location resources that reference this Endpoint
- `_revinclude=PractitionerRole:endpoint` - Include PractitionerRole resources that reference this Endpoint
- `_revinclude=Provenance:target` - Include Provenance resources that track changes to this Endpoint

#### Example usage

    GET /Endpoint/303?_revinclude=HealthcareService:endpoint&_revinclude=Location:endpoint

This query returns the Endpoint resource along with all HealthcareServices and Locations that use this Endpoint.
