The first Australian Atlas of Healthcare Variation (the first Atlas) presents a clear picture of substantial variation in healthcare use across Australia.
This Atlas, the first to be released by the Commission, illuminates variation by mapping use of health care according to where people live. As well, this Atlas identifies specific achievable actions for exploration and quality improvement.
Included in the first Atlas is health care related to: antibiotic prescribing, surgical, mental health and diagnostic services.
Priority areas for investigation and action arising from the first Atlas include use of:
Some variation is expected and associated with need-related factors such as underlying differences in the health of specific populations, or personal preferences. However, the weight of evidence in Australia and internationally suggests that much of the variation documented in the Atlas is likely to be unwarranted. Understanding this variation is critical to improving the quality, value and appropriateness of health care.
The first Atlas, released in November 2015, examined six clinical themes covering prescribing, diagnostic, medical and surgical interventions.
Key findings and recommendations for action are available here.

The first Atlas shows rates of use of healthcare (prescriptions, surgical procedures, hospitalisations) in geographical local areas across Australia. The rate is age and sex standardised to allow comparisons between populations with different age and sex structures. All rates are based on the patient’s place of residence, not the location of the hospital or health service.
The first Atlas uses data from national databases to explore variation across different healthcare settings. These included the Medicare Benefits Schedule (MBS), Pharmaceutical Benefits Scheme (PBS) and the Admitted Patient Care National Minimum Data Set (APC NMDS).
The geographic local areas used are Australian Bureau of Statistics (ABS) standard geographical regions known as Statistical Areas Level 3 (SA3). SA3s provide a standardised regional breakup to assist in analysing data at the regional level. A number of items are mapped at the larger Statistical Area Level 4 (SA4).
The Commission worked with the National Health Performance Authority on the first Atlas.
The Commission consulted widely with the Australian government, state and territory governments, specialist medical colleges, clinicians and consumer representatives to develop the Atlas.
