Description

Acute care

 

Presented as a number per 100,000 people.

Rates are directly age- and sex- standardised, to the 2001 Australian population aged 35-84, using 5-year age groups: 35-39, 40-44, … , 80-84.

Indigenous and other Australian rates are directly age and sex standardised, to the 2001 Australian population aged 35-84, using 5-year age groups: 35-39, 40-44, … , 60–64, 65-84.

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) is based on Statistical Area Level 2 (SA2) of usual residence of the patient.

Suppress data (number or 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 20

Age and sex standardised rates are suppressed where the denominator for at least one of the age and sex groups used to calculate the rate is below 30.

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 333 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 50 with fewer than 30,000 people and 35 with more than 130,000 as at 30 June 2011. For further information see the ABS publication, Australian Statistical Geography Standard (ASGS): Volume 1 – Main Structure and Greater Capital City Statistical Areas, July 2011 (cat. no. 1270.0.55.001).

 

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. 

Private hospitals include private free-standing day hospital facilities and other private hospitals (which also include private psychiatric hospitals).

 

For additional context, the proportion of hospitalisations involving a transfer to another acute hospital (mode of separation = 1) was also provided.
