Presented as a number of hospitalisations per 100,000 people.

Rates are directly age-sex standardised, to the 2001 Australian population  aged 18 years and over, using 5-year age groups: 18-24, 25-29, … , 80-84, 85 and over.

Indigenous and other Australian rates are directly age-sex standardised, to the 2001 Australian population aged 18 years and over, using 5-year age groups: 18-24, 25-29, … , 60–64, 65 and over.

For more information about age-standardisation in general see http://meteor.aihw.gov.au/content/index.phtml/itemId/327276

 

Analysis by Statistical Area Level 3 (SA3) 2016 is based on Statistical Area Level 2 (SA2) 2011 of usual residence of the patient, converted to SA3 (ASGS 2016) equivalents through an ABS concordance file.

 

Suppress data (number and rate) if at least one of the following conditions are met:

·           the total denominator is less than 1,000

·           the total numerator is less than 10.

 

Age-sex standardised rates are also suppressed where the denominator for at least one of the age-sex groups used to calculate the rate is below 30 and results of sensitivity analysis indicate that the rates are volatile. However, for SA3 data, if the volatility of the rate is not found to have a material impact on its decile, the rate is published with caution. For more information about the sensitivity analysis, see the Technical supplement of the Third Atlas.

Methodology:Help on this term

Statistical Area Level 3 (SA3s) are geographic areas defined in the ABS Australian Statistical Geography Standard (ASGS). The aim of SA3s is to create a standard framework for the analysis of ABS data at the regional level through clustering groups of SA2s that have similar regional characteristics. There are 340 spatial SA3s covering the whole of Australia without gaps or overlaps. They are designed to provide a regional breakdown of Australia. SA3s generally have a population of between 30,000 and 130,000 people. There are approximately 78 with fewer than 30,000 people and 46 with more than 130,000 as at 30 June 2016. The Other Territories of Jervis Bay, Cocos (Keeling) Islands, Christmas Island and Norfolk Island are each represented by a SA3 in the 2016 ASGS. For further information see the ABS publication, Population by Age and Sex, Regions of Australia, 2016. ABS. cat. no. 3235.0.

 

The scope of the NHMD is episodes of care for admitted patients in all public and private acute and psychiatric hospitals, free-standing day hospital facilities and alcohol and drug treatment centres in Australia. Hospitals operated by the Australian Defence Force, corrections authorities and in Australia’s off-shore territories are not in scope, but some are included. 

 

ACHI and ICD-10-AM 8th editions were used for 2014–15 data and ACHI and ICD-10-AM 9th editions were used for 2015–16 and 2016–17 data.
