Presentation of results
The web update presents information by PHN areas - 31 geographic areas covering Australia, with boundaries defined by the Australian Government Department of Health.2
The quality of estimates from the ABS Patient Experience Survey can vary substantially across PHN areas as the survey was not specifically designed to produce estimates at this level of geography. To ensure robust reporting of these data by PHN areas, suppression or interpret with caution rules were developed and applied by the Australian Institute of Health and Welfare.
Estimates of a percentage or its complement that had a relative standard error greater than 50% were suppressed. These estimates were considered unreliable for most practical purposes.
Data for PHN areas were suppressed if there was the likelihood of a non-representative sample, that is, where the survey sample count in the PHN area was less than 10% of the expected number of adults.
The ‘interpret with caution’ flag was applied to data if the relative standard error associated with the percentage or its complement was greater than 25%.
The estimates for the Northern Territory were not considered sufficiently representative to publish on the National overviews page of the MyHealthyCommunities website. This is because the survey excludes the Indigenous Community Strata (encompassing discrete Aboriginal and Torres Strait Islander communities) which comprises around 25% of the estimated resident population in the Northern Territory living in private dwellings. Estimates have been made available as part of the ‘Download the data’ Excel file with an ‘interpret with caution’ flag and caveat.
