The classification system used to code hospital admissions data, ICD-10-AM, uses the term ‘mechanism’ to refer to the external cause of a self-inflicted injury. Throughout Suicide & self-harm monitoring ‘mechanism’ has been used in data visualisations, while the term ‘method’ has been used in the accompanying text.
Hospitalisations data for patients with intentional self-harm injuries includes those with and without suicidal intent. For further information see Technical notes.
Hospitalisations for intentional self-harm, by age, sex and mechanism, Australia, 2008–09 to 2020–21.
The line graph shows the age-specific rates of intentional self-harm hospitalisations for persons of all ages from 2008–09 to 2020–21 by method of self-harm. Users can also choose to view age-specific rate, numbers, and proportion of hospitalisations for intentional self-harm by sex for each age group. From 2008–09 to 2020–21, the highest rates of intentional self-harm hospitalisations by method were for self-poisoning by drugs in the nonopioid analgesics, antipyretics and antirheumatics drugs category, which has been the highest rate of mechanism also in 2012–13 and 2016–17. For all other years anti-epileptic, sedative-hypnotic, anti-parkinsonism and psychotropic drugs was the highest category. The third highest rates during the 10-year period were for self-injury with sharp object.
Between 2008–09 and 2020–21, the 2 most common methods of self-harm resulting in hospitalisation were:
Contact with sharp objects (X78) was another common method of self-harm resulting in hospitalisation.
Hanging (X70) and Gas (X67) were the only methods of intentional self-harm that resulted in more male hospitalisations than female in 2020–21 (507 and 314 hospitalisations, and 133 and 33 hospitalisations, respectively).
