Data quality

Quality statement summary:Help on this term
  • The National Hospital Morbidity Database (NHMD) is a comprehensive dataset that has records for all separations of admitted patients from essentially all public and private hospitals in Australia.
  • Data on diagnoses are recorded uniformly using the International Statistical Classification of Diseases and Related Health Problems, 10th revision, Australian modification.
  • Numerators for remoteness and socioeconomic status are based on the reported area of usual residence of the patient, regardless of the jurisdiction of residence. Hence there are mismatches between numerators and denominators that affect interpretation of rates.
  • Interpretation of rates for jurisdictions should take into consideration cross-border flows, particularly for the ACT.
  • The hospital separations data do not include injuries that are treated in the emergency department and do not require admission to hospital.
  • Multiple separations may arise from a single injury or poisoning event.
  • Variations in admission practices and policies lead to variation among providers in the number of admissions for some conditions.
Institutional environment:Help on this term

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 and private 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:Help on this termThe reference period for this data set is 2007–08.
Accessibility:Help on this term

The AIHW provides a variety of products that draw upon the NHMD. Published products available on the AIHW website are:

  • Australian hospital statistics with associated Excel tables.
  • Interactive data cube for Admitted patient care (for Principal diagnoses, procedures and Diagnosis Related Groups).
Interpretability:Help on this termSupporting information on the quality and use of the NHMD are published annually in Australian hospital statistics (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, the quality of Indigenous data, and changes in service delivery that might affect interpretation of the published data. Metadata information for the NMDS for Admitted patient care are published in the AIHW’s online metadata repository —METeOR, and the National health data dictionary.
Relevance:Help on this term

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 analyses by remoteness and socioeconomic status are based on Statistical Local Area of usual residence of the patient. Separations are reported by jurisdiction of hospitalisation, regardless of the jurisdiction of usual residence. Hence, rates represent the number of separations for each remoteness area or SEIFA population group (regardless of the jurisdiction in which the patient resides) divided by the number of people in that remoteness or SEIFA population group in the jurisdiction of hospitalisation. Therefore, there will be mismatches between the numerators and denominators for separation rates. Mismatches are particularly relevant if significant numbers of one jurisdiction’s residents are treated in another jurisdiction. Hospital separations data do not include injuries that are treated in the emergency department that do not require admission to hospital. Multiple separations may arise from a single injury or poisoning event.

The hospital separations data do not include injuries that are treated in the emergency department and do not require admission to hospital.

Multiple separations may arise from a single injury or poisoning event.

Variations in admission practices and policies lead to variation among providers in the number of admissions for some conditions.

Separations are reported by jurisdiction of hospitalisation. The injury event will not necessarily have occurred in the state or territory of hospitalisation.

Accuracy:Help on this term

For 2007–08, almost all public hospitals provided data for the NHMD, with the exception of a mothercraft hospital in the ACT. The great majority of private hospitals also provided data, the exceptions being the private day hospital facilities in the ACT, the single private free-standing day hospital facility in the NT, and a small private hospital in Victoria.

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 the states and territories prior to submission ot the AIHW. The AIHW then undertakes extensive validations 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.

Data on diagnoses are recorded uniformly using the International Statistical Classification of Diseases and Related Health Problems, 10th revision, Australian modification.

The Indigenous status data are of sufficient quality for statistical reporting purposes for the following jurisdictions: NSW, Vic, Qld, SA, WA, NT (NT public hospitals only).

Cells have been suppressed to protect confidentiality (where the presentation could identify a patient or a single service provider), where rates are likely to be highly volatile (for example, the denominator is very small), or data quality is known to be of insufficient quality (for example, where Indigenous identification rates are low).

Coherence:Help on this termThe information presented for this indicator is calculated using the same methodology as data published in Australian hospital statistics 2007–08, except that for the Indigenous disaggregation age standardisation is to 64 years here, rather than to 74 as in Australian hospital statistics.
