|Quality statement summary:|
The Australian Institute of Health and Welfare (AIHW) has calculated this indicator.
The AIHW is an independent statutory authority within the Health and Ageing portfolio, which is accountable to the Parliament of Australia through the Minister for Health and Ageing. For further information see the AIHW website.
The data were supplied to the AIHW by state and territory health authorities. 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 administrative arrangements, contractual requirements or legislation.
States and territories supplied these data under the terms of the National Health Information Agreement (see link below).
The reference period for these data is 2009–10 and 2010–2011.
The AIHW provides a variety of products that draw upon NESWTDC and NHMD data. Published products available on the AIHW website are:
Some data are also included on the MyHospitals website.
|Interpretability:||Supporting information on the quality and use of the NESWTDC and NHMD are published annually in Australian hospital statistics (technical appendixes), available in hard copy or on the AIHW website. Readers are advised to note caveat information to ensure appropriate interpretation of the performance indicator. Supporting information includes discussion of coverage, completeness of coding, the quality of Indigenous data, and changes in service delivery that might affect interpretation of the published data. Metadata information for the NMDSs for Elective Surgery Waiting Times and Admitted Patient Care are published in the AIHW’s online metadata repository (METeOR) and the National health data dictionary.|
The purpose of the NMDS for Elective surgery waiting times (removals data) is to collect information about patients waiting for elective surgery in public hospitals. The scope of this NMDS is patients removed from waiting lists for elective surgery which are managed by public acute hospitals. This includes private patients treated in public hospitals and may include public patients treated in private hospitals.
The purpose of the NMDS for Admitted patient care is to collect information about care provided to admitted patients in Australian hospitals. The scope of the NMDS is episodes of care for admitted patients in essentially all hospitals in Australia, including public and private acute and psychiatric hospitals, free-standing day hospital facilities, alcohol and drug treatment hospitals and dental hospitals. Hospitals operated by the Australian Defence Force, corrections authorities and in Australia's off-shore territories are not included. Hospitals specialising in ophthalmic aids and other specialised acute medical or surgical care are included.
Analyses by remoteness and socioeconomic status are based on the Statistical Local Area (SLA) of usual residence of the patient. The Socio-Economic Indexes for Areas (SEIFA) categories for socioeconomic status represent approximately the same proportion of the national population, but do not necessarily represent that proportion of the population in each state or territory (each SEIFA decile or quintile represents 10 per cent and 20 per cent respectively of the national population). The SEIFA scores for each SLA are derived from 2006 Census data and represent the attributes of the population in that SLA in 2006. To allocate a 2006 SEIFA score to 2009 SLAs (used for 2009–10 data) or 2010 SLAs (used for 2010–11 data), the 2009/2010 SLA boundaries are mapped backed to 2006 SLA boundaries. It is possible that the demographic profile of some areas may have changed between 2006 and 2009 (2010) due to changes in the socioeconomic status of the existing population, or changes to population size, thus potentially diminishing the accuracy of that area’s SEIFA score over time. This is likely to impact most those quintiles in jurisdictions with a greater number of areas experiencing substantial population movement or renewal.
Separations are reported by jurisdiction of hospitalisation, regardless of the jurisdiction of usual residence. Hence, data represent the waiting time for patients living in each remoteness area or SEIFA population group (regardless of their jurisdiction of residence) for the reporting jurisdiction. This is relevant if significant numbers of one jurisdiction’s residents are treated in another jurisdiction.
Other Australians includes separations for non‑Indigenous people and those for whom Indigenous status was not stated.
For 2009–10 and 2010–11:
Interpretation of waiting times for jurisdictions should take into consideration cross-border flows, particularly for the Australian Capital Territory.
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. Where possible, data in individual datasets are checked against data from other datasets. 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.
Cells have been suppressed to protect confidentiality where the presentation could identify a patient or a service provider or where rates are likely to be highly volatile, for example, where the denominator is very small. The following rules were applied:
The data can be meaningfully compared across reference periods, except for the Indigenous disaggregation. Caution should be used in comparing data by peer groups across reference years, as the number of hospitals classified as peer group A or B, or the peer group of a hospital, may vary over time.
Caution is also required when analysing SEIFA over time for the reasons outlined above (see Relevance section). Methodological variations also exist in the application of SEIFA to various data sets and performance indicators. Any comparisons of the SEIFA analysis for this indicator with other related SEIFA analysis should be undertaken with careful consideration of the methods used, in particular the SEIFA index used and the approach taken to derive quintiles and deciles.
The information presented for this indicator is based on the same data as published in, Australian hospital statistics 2009–10, Australian hospital statistics: emergency department care and elective surgery waiting times (report series) and the National Healthcare Agreement: performance report 2009–10.
However, some 2009–10 data reported previously in these publications are different from the equivalent data published here because the hospitals classified as peer groups A and B were based on 2008–09, rather than 2009–10 peer groups. Caution should be exercised when interpreting the 2011–10 data as potential revisions to the 2011–2010 NESWTDC data could exist once both the availability and linking to the 2011–10 NHMD has occurred.
Analyses presented in Australian hospital statistics and previous National Healthcare Agreement performance reports may also differ slightly depending on whether the NESWTDC or linked NESWTDC/NHMD was used.
