This identifier profile defines a patient internal identifier in an Australian context. A patient internal identifier is assigned to a patient by an application (e.g. practice management system or a cloud-based electronic medical record) to uniquely identify a patient within that application.

While a patient internal identifier can be exchanged with other applications, its scope for sharing is limited and typically occurs for context-specific patient matching (e.g. a patient internal identifier included in a pathology request can be returned in the associated pathology report). This identifier is only unique within the assigning application and is not suitable for broader use as a persistent identifier, unlike a Medical Record Number (MRN), which is unique within an institution.

Usage Notes

Profile specific implementation guidance:

  • The scope of patient internal identifier and MRN differ in that:
    • An MRN uniquely identifies a patient in a specific institution (e.g. a hospital), and is intended to be referenced and shared by different applications within that institution. An MRN is assigned and managed by an assigning application (e.g. a Patient Master Index).
    • A patient internal identifier uniquely identifies a patient within an application, and is not intended to be broadly shared with other applications.
  • When constructing local identifiers such as a patient internal identifier, see the guidance in Business Identifiers.
