National Healthcare Agreement: P42-Intentional self-harm in hospitals, 2010 Health, Superseded 08/06/2011
|Quality statement summary:|
The Australian Institute of Health and Welfare (AIHW) has calculated this indicator. The data were supplied to the AIHW 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 AIHW 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 are 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 National Hospital Morbidity Database. Published products available on the AIHW website are:
|Interpretability:||Supporting information on the quality and use of the National Hospital Morbidity Database are published annually in Australian hospital statistics (technical appendixes), available in hard copy or on the AIHW website. Supporting information includes discussion of coverage, completeness of coding, the quality of Indigenous data, and variation in service delivery that might affect interpretation of the published data. Metadata information for the Admitted patient care national minimum data set (NMDS) are published in the AIHW’s online metadata repository, METeOR, and the National health data dictionary.|
The purpose of the Admitted patient care NMDS 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.
For 2007–08, 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. The AIHW does not have direct access to hospital records to determine the accuracy of the data provided. However, it undertakes extensive validations on receipt of data. Data are checked for valid values, logical consistency and historical consistency. Where possible, data in individual data sets are checked with data from other data sets. 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 or missing or incorrect values.
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).
‘Patient harm’ is defined as conditions meeting the definition of Additional diagnosis in the Admitted Patient Care NMDS.
The specification for the indicator defines a separation involving self harm as being one for which the place of occurrence is a Health service area. The Health service area as a place of occurrence is broader in scope than hospitals – it includes other health care settings such as day surgery centres or hospices. Hence, the numbers presented could be an over-estimate as they may include separations involving intentional self-harm occurring in health service areas other than ‘hospitals’.
Around 30% of all separations involving intentional self harm did not have a code assigned for the place of occurrence. Consequently, the recorded number of separations involving intentional self-harm hospital may be an under-estimate.
If there is more than one external cause reported, there is uncertainty about whether the place of occurrence ‘health service area’ relates to the fall or to the other external cause. As a consequence there may be some over-counting in the calculation of the indicator.
In the calculation of the indicator, separations with a principal diagnosis of an injury or poisoning have been excluded on the assumption that the self-harm occurred prior to admission to hospital. However, it is possible that some of these separations would have additionally involved self-harm that occurred in hospital.
The issue of whether a patient who self harms while on leave from hospital has not been addressed in the specification of the indicator.
Data on self-harm are recorded uniformly using the ICD-10-AM.
The comparability of the data will be affected by the fact that it has not been adjusted for differences in casemix (for example, patient age).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:||The information presented for this indicator is calculated using the same methodology as data published in Australian hospital statistics 2007–08.|
