|Quality statement summary:|
The Australian Institute of Health and Welfare (AIHW) is a major national agency set up by the Australian Government under the Australian Institute of Health and Welfare Act 1987to provide reliable, regular and relevant information and statistics on Australia’s health and welfare. It is an independent corporate Commonwealth entity governed by a management board, and accountable to the Australian Parliament through the Health portfolio.
The AIHW aims to improve the health and wellbeing of Australians through better health and welfare information and statistics. It collects and reports information on a wide range of topics and issues, ranging from health and welfare expenditure, hospitals, disease and injury, and mental health, to ageing, homelessness, disability and child protection.
The Institute also plays a role in developing and maintaining national metadata standards. This work contributes to improving the quality and consistency of national health and welfare statistics. The Institute works closely with governments and non-government organisations to achieve greater adherence to these standards in administrative data collections to promote national consistency and comparability of data and reporting.
One of the main functions of the AIHW is to work with the states and territories to improve the quality of administrative data and, where possible, to compile national datasets based on data from each jurisdiction, to analyse these datasets and disseminate information and statistics.
The Australian Institute of Health and Welfare Act 1987, in conjunction with compliance to the Privacy Act 1988 (Commonwealth), ensures that the data collections managed by the AIHW are kept securely and under the strictest conditions with respect to privacy and confidentiality.
For further information see the AIHW website.
Data for the NNAPEDCD were supplied to the AIHW by state and territory health authorities under the terms of the National Health Information Agreement (see the following links):
The state and territory health authorities received these data from public hospitals. States and territories use these data for service planning, monitoring and internal and public reporting. Hospitals may be required to provide data to states and territories through a variety of administrative arrangements, contractual requirements or legislation.
The reference period for these data is 2015–16.
The financial year of 2011–12 is the first reporting period that these data are available according the agreed specification.
For 2015–16, Australian Capital Territory emergency department care information was not available at the time of publication.
The AIHW provides a variety of products that draw upon the NNAPEDCD. Published products available on the AIHW website include the Emergency department care: Australian hospital statistics series of reports with associated Excel tables. These products may be accessed on the AIHW website at: http://www.aihw.gov.au/hospitals/
Metadata information for the NAPEDC NMDS and the NAPEDC DSS are published in the AIHW’s online metadata repository, METeOR, and the National health data dictionary.

The Data Quality Statement for the 2014–15 NNAPEDCD can be accessed on the AIHW website at:
The purpose of the NNAPEDCD is to collect information on the characteristics of emergency department care (including waiting times for care) for non-admitted patients registered for care in emergency departments in public hospitals. For the years 2003–04 to 2012–13 inclusive, the scope of the NNAPEDCD was public hospitals classified as either Principal referral and specialist women’s and children’s hospitals (peer group A) or Large hospitals (peer group B).
From 2013–14, the scope of the NNAPEDCD was patients registered for care in emergency departments in public hospitals where the emergency department meets the following criteria:
The data presented here are not necessarily representative of hospitals not included in the NNAPEDCD.
For 2015 and prior reporting periods, the indicator included only peer group A (Principal referral and specialist women’s and children’s hospitals), peer group B (Large hospitals) and the Mersey Community Hospital. For the 2016 and this reporting period, the scope of the indicator has been increased to all public hospitals reporting to the NNAPEDCD. Data for 2013–14 have previously been supplied for the revised scope. It is not possible to provide comparable data for the years prior to 2013–14, thus data for 2012–13 and previous years for this indicator are not directly comparable with data for 2013–14 and subsequent years.
For 2013–14, 2014–15 and 2015–16, the coverage of the NNAPEDCD collection is considered complete for public hospitals with an emergency department meeting the criteria above. Most emergency presentations to hospitals where the emergency department does not meet the definition of an emergency department as defined above are not reported to the NNAPEDCD. For 2014–15 it was estimated that 88% of emergency presentations were reported in the NNAPEDCD.
Data are reported by jurisdiction of presentation, regardless of the jurisdiction of usual residence.
States and territories are primarily responsible for the quality of the data they provide. However, the AIHW undertakes extensive validations on data. Data are checked for valid values, logical consistency and historical consistency. Potential errors are queried with jurisdictions, and corrections and resubmissions may be made in response to these queries. The AIHW does not adjust data to account for possible data errors or missing or incorrect values.
As discussed in the Relevance section above, the scope of the indicator has been increased to all public hospitals reporting to the NNAPEDCD. Data for 2013–14 have previously been resupplied for the revised scope. It is not possible to provide comparable data for the years prior to 2013–14. Any comparison of data over time should take into account changes in scope, coverage and administrative and reporting arrangements.
The information presented for this indicator is calculated using the same methodology as data published in Emergency department care: Australian hospital statistics (report series).
