National Health Data Hub

The National Health Data Hub (NHDH), previously the National Integrated Health Services Information (NIHSI), is a major national de-identified linked data system for health research and analysis. The NHDH brings together core government administrative health and aged care datasets. It comprises data on admitted patient care services (in public and some private hospitals), emergency department services and outpatient services in public hospitals for all states and territories except for Western Australia and the Northern Territory.
The NHDH also includes data from the Medicare Benefits Schedule (MBS), Pharmaceutical Benefits Scheme (PBS), Repatriation Pharmaceutical Benefits Scheme (RPBS), Aged care services data, National Death Index (NDI), Australian Immunisation Register (AIR) data, National Disability Insurance Scheme (NDIS), and Australian New Zealand Intensive Care Society (ANZICS).
Researchers can use the NHDH data linkage system to explore issues such as validation of the current health treatment pathways for chronic disease management and care.
