People with previous suicide attempts

A previous suicide attempt is the largest single factor indicating future suicide risk and death by suicide.

In Australia, suicide attempts occur most frequently between ages 15-44 years. Young people aged 15-24 also have high risk of a suicide attempt, and women have the highest rate of multiple attempts across all age groups.

Following a suicide attempt, the risk period for re-attempt is highest on the first day after an attempt and continues to remain high consecutive week following an attempt, regardless of admission to psychiatric or medical care.

The risk of re-attempting suicide remains high throughout a person’s lifetime, but is particularly heightened in the initial year following an attempt.

The risk remains approximately four times higher than those with no history of a suicide attempt five years post-attempt.

Adhering to a care plan and regular medical appointments during this period can help to reduce the risk of a re-attempt.

The presence of personality disorders, particularly major affective disorder and schizophrenia, increases risk of suicide re-attempt. Depressive illness can also contribute to a person’s risk of suicide, although anxiety disorders can be viewed as a protective factor, with evidence suggesting suicide re-attempts are less common in those with diagnosed anxiety disorders.

2017 data shows that approximately 80% of suicide deaths had comorbidities as contributing factors. Mood disorders such as depression were the most common mentioned condition, being present in 43% of deaths1.

Compliance with individual care plans, including adhering to prescribed medication schedules and behavioural therapy can help prevent suicide re-attempts. Similarly, removing access to lethal means, the presence of strong social connections and an awareness of the help services available can also reduce the risk of a person re-attempting suicide.

Understanding protective and risk factors for suicide re-attempts in Australia would be enhanced with further research in this area.
