Presented as a number of people dispensed 5 or more medicines per 100,000 people. 

Rates are directly age-sex standardised, to the 30 June 2001 Australian population, using 5-year age groups: 75-79, 80-84, 85 and over.

For more information about age-standardisation in general see the glossary item Age-standardised rate. 

A patient’s age is calculated in years as the difference between the patient’s date of birth and date of supply for the prescription. A patient can be in two age groups if the patient was dispensed ten prescriptions before their birthday, and ten prescriptions after their birthday. In this example, half a patient is allocated to the two age groups. Date of birth and sex are as reported on a patient’s last prescription for any medicine, extracted on 07/04/2020.

Prescriptions are allocated to a financial year based on the date the medicine was supplied to the patient.

Analysis by Statistical Area Level 3 (SA3) 2016 is based on the patient's enrolment postcode as last reported by the patient to Medicare, valid at date of supply. If the postcode cannot be allocated to a SA3 (for example, an invalid postcode), the postcode is replaced with the postcode of the dispensing pharmacy.

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

  • the total denominator is less than 200
  • the total numerator is less than 20

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 Fourth Atlas

Consequential suppression may be applied to preserve confidentialised data.

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 Anatomical Therapeutic Chemical (ATC) code is recommended by the World Health Organization (WHO) as an internationally accepted classification for presenting and comparing drug usage data. Since 1982, the WHO Collaborating Centre for Drug Statistics Methodology (WHOCC), located in Norway, has been the central body responsible for coordinating ATC use. Note that the ATC codes used in this specification are from the Australian Department of Health’s version of the WHO ATC classifications, which have some minor differences from the WHO version, based upon a particular drug’s usage in Australia. For further information, please see the Department of Health’s ATC version.

The mapping of PBS drugs to ATC codes is available via the Item Code to Drug Mapping File.      

This indicator is based on the OECD Prescribing Indicator 8 (page 57).
