National Healthcare Agreement: P69-Cost per casemix adjusted separation, 2010
|Quality statement summary:|
The Australian Institute of Health and Welfare (AIHW) has calculated this indicator. The data were supplied to the Institute 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.
The Institute is an independent statutory authority within the Health and Ageing portfolio, which is accountable to the Parliament of Australia through the Minister. For further information see the AIHW website.
Hospitals may be required to provide data to states and territories through a variety of administrative arrangements, contractual requirements or legislation.
States and territories supplied these data under the terms of the National Health Information Agreement (see link).
|Timeliness:||The reference period for this data set is 2007–08.|
The AIHW provides a variety of products that draw upon the NHMD and the NPHED. Published products available on the AIHW website include:
|Interpretability:||Supporting information on the quality and use of the NPHED and NHMD are published annually in Australian hospital statistics (particularly chapters 3, 4 and technical appendixes), available in hard copy or on the AIHW website. Readers are advised to read caveat information to ensure appropriate interpretation of the performance indicator. Supporting information includes discussion of coverage, completeness of coding, changes in accounting methods and changes in service delivery that might affect interpretation of the published data. Metadata information for the NMDS for Public hospital establishments 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 Public hospital establishments is to collect information on the characteristics of public hospitals and summary information on non-admitted services provided by them. The scope is public hospitals in Australia, including public acute hospitals, psychiatric hospitals, drug and alcohol hospitals and dental hospitals in all states and territories. The collection covers hospitals within the jurisdiction of the state and territory health authorities. Hence, public hospitals not administered by the state and territory health authorities (hospitals operated by the Department of Health and Ageing, or correctional authorities for example, and hospitals located in offshore territories) are not included. The collection does not include data for 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 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 may also be included. Hospitals specialising in dental, ophthalmic aids and other specialised acute medical or surgical care are included.
The scope of the analysis includes public hospitals that provide mainly acute care. These are the hospitals in the public hospital peer groups of Principal referral and specialist womens’ and children’s hospitals, Large hospitals, Medium hospitals, and Small acute hospitals. Excluded are Small non-acute hospitals, Multi-purpose services, Hospices, Rehabilitation hospitals, Mothercraft hospitals, Other non-acute hospitals, Psychiatric hospitals, and hospitals in the Unpeered and other hospitals peer group. Also excluded are hospitals for which expenditure or admitted patient care data were incomplete, although most of these were excluded for other reasons (for example they are small non-acute hospitals).
For 2007–08, coverage of the NPHED was essentially complete.
The data are defined in the NMDS for Public hospital establishments. However, differences in admission practices, counting and classification practices across jurisdictions may affect the comparability of these data.
For 2007–08, almost all public hospitals provided data for the NHMD, with the exception of a mothercraft hospital in the ACT.
Inaccurate responses may occur in all data provided to the AIHW, and the AIHW does not have direct access to jurisdictional records to determine the accuracy of the data provided. However, routine data quality checks are conducted by states and territories prior to submission to the AIHW. The AIHW then undertakes extensive validation on receipt of 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 edit queries. The AIHW does not adjust data to account for possible data errors.
The calculation of the cost per casemix adjusted separation is sensitive to a number of deficiencies in available data:
Cells have been suppressed to protect confidentiality (where the numerator would identify a single service provider).
|Coherence:||The information presented for this indicator is calculated using the same methodology as data published in Australian hospital statistics 2007–08. This information has been recalculated based on 2007-08 AR-DRG version 5.1 cost weights (DoHA 2009).|
