Health Identifiers

Australian Health Identifier integration services

Health Identifiers are the backbone of patient and provider identity in Australian digital health. IHIs for patients, HPI-Is for practitioners, and HPI-Os for organisations must be validated, stored, and used correctly across your systems.

Common challenges

What teams struggle with

IHI validation complexity

IHIs have check digits, status states (active, retired, deceased), and must be verified against HI Service in real time or via batch.

Patient demographic matching

Matching patients to the correct IHI when names are misspelled, dates vary, or duplicates exist requires robust algorithms.

Provider identifier management

HPI-I and HPI-O must be linked to the correct clinicians and sites — errors break myHealth Record authentication.

Batch vs online lookup

High-volume systems need efficient batch IHI allocation without blocking clinical workflows.

Questions about health identifier services

Is IHI lookup mandatory?

For myHealth Record integration and many ADHA services, yes. Even without myHR, IHIs improve patient matching and reduce duplicate records.
