This identifier profile defines a unique identifier allocated to a healthcare endpoint, in a Health Connect provider directory context.

HC Endpoint Identifier (HC-EPI)

The HC-EPI is the primary external identifier used to identify an Endpoint across Health Connect. Publishers SHOULD provide an authoritative external identifier when creating or updating an Endpoint. The HC-EPI is mandatory for Endpoint resources published in the Health Connect directory and is used as a primary reconciliation key for cross-system matching.

  • identifier.type: fixed to RI (resource identifier).
  • identifier.value: the external identifier value supplied by the publisher or assigning organisation.
  • identifier.system: populate with a stable URI to support authoritative reconciliation.

Guidance:

  • The combination of system and value MUST be globally unique within Health Connect and SHOULD be stable over the lifecycle of the endpoint.
  • Use identifier.system to record a canonical URI when organisations have a stable namespace for their identifiers.

Usages:
