Computation description:Help on this term

Excludes separations with a principal diagnosis of an injury or poisoning (ICD-10-AM codes beginning with S and T).

Intentional self-harm is identified by ICD-10-AM external cause codes X60–X84. Self-harm is defined in ICD-10-AM as ‘Intentional self-harm: includes purposefully-inflicted poisoning or injury, suicide and attempted suicide.’

Place of occurrence of 'Health service area' is identified by ICD-10 code Y92.22.

Presented as number only, and per 1,000 separations.

Specification: Interim

Introduction of the condition onset flag from 2008–09 should assist in refinement of this specification to limit the numerator to incidents of self-harm occurring in hospital, and exclude self-harm in health services areas occurring prior to admission.

The long-term specifications should exclude patients who self-harmed while on leave from hospital. The extent to which the place of occurrence data and the self-harm data are reported accurately is unknown and may be worth investigating. Better linkage of external cause codes and place of occurrence codes could also be useful.

Most recent data available for 2010 CRC baseline report: 2007-08
Other issues caveats:Help on this term

Disaggregations within individual jurisdictions will be limited by data quality considerations. Some disaggregations may result in numbers too small for publication.

Excludes private hospitals in Tasmania, the ACT and NT. 

Note that the interim specifications for this indicator include separations that involved a self-harm incident which occurred in any health service area, not just hospitals. This may mean that the data will be an over-count. However, the quality of the place of occurrence data is unknown.

The interim specifications for this indicator also include separations that involved leave days. The place of occurrence data (for ‘health service area’) should exclude instances of self-harm that occurred while a patient was on leave (because they would probably not be in a ‘health service area’ while on leave). However, it is not known whether the quality of the place of occurrence data allows such a conclusion to be drawn.

If there is more than one external cause reported, there will be some uncertainty about whether the place of occurrence ‘health service area’ relates to the self-harm external cause or to the other external cause(s) that could result in an over-count or an under-count.

The quality of data on Indigenous status is not considered to be adequate for analysis purposes for the ACT and Tasmania.
