Tips on using the data cubes

Please refer to the Hospitals AR-DRG data cube user guide for instructions on using and downloading from the data cubes.

Data source(s)

The source of these data is the AIHW National Hospital Morbidity Database.  It contains AR-DRG information for separations for which the care type was specifically reported as Acute, Newborn (for separations with at least one qualified day) or was not reported (see the Glossary). More information on the AR-DRGs reported for admitted patients are available in the Australian hospital statistics reports.


In order to maintain confidentiality some data have been suppressed at the Diagnosis Related Group and/or surgical/medical/other partition level. Data for the suppressed categories will be included in the MDC and grand totals.
