Key Points
- Direct warning signs (highest priority): threatening to hurt/kill oneself, seeking access to lethal means, talking/writing about death or suicide, making preparations
- IS PATH WARM mnemonic captures key indirect warning signs: Ideation, Substance abuse, Purposelessness, Anxiety, Trapped, Hopelessness, Withdrawal, Anger, Recklessness, Mood changes
- Use of multiple self-harm methods and early non-fatal repetition should be considered a red-flag indicator of suicidal risk
- Risk factor checklists alone should not determine treatment decisions; comprehensive psychosocial assessment with structured clinical judgement is recommended
Direct Warning Signs (Highest Priority)
These warrant immediate further assessment:
- Suicidal communication: threatening to hurt or kill oneself, talking about wanting to die, ominous statements such as "everyone would be better off without me"
- Seeking access to means: looking for pills, weapons, or other lethal methods
- Making preparations: writing about death/dying/suicide, putting affairs in order, giving away possessions, writing goodbye letters
Indirect Warning Signs
The IS PATH WARM mnemonic is a useful clinical aide-memoire:
| Letter | Sign | Description |
|---|---|---|
| I | Ideation | Suicidal thoughts |
| S | Substance abuse | Increasing alcohol/drug use |
| P | Purposelessness | No sense of purpose or reason for living |
| A | Anxiety | Agitation, insomnia, severe anxiety |
| T | Trapped | Feeling there is no way out |
| H | Hopelessness | Pervasive hopelessness about the future |
| W | Withdrawal | Increasing social isolation |
| A | Anger | Rage, uncontrolled anger, revenge-seeking |
| R | Recklessness | Impulsive/risky behaviour without regard for safety |
| M | Mood changes | Dramatic or significant mood shifts |
Behavioural and Conversational Cues
- Unexplained crying, emotional outbursts
- Neglect of personal hygiene/appearance
- Changes in sleep and appetite
- Saying things like: "I can't take this anymore," "What's the point?," "I just want the pain to stop"
Key Risk Factors to Consider Alongside Warning Signs
- Prior suicide attempt (strongest predictor of future attempts)
- Mental health disorders, particularly mood disorders, psychosis, and substance use disorders
- Recent psychosocial stressors: relationship breakdown, job loss, financial strain, bereavement, legal issues
- Family history of suicide
- Chronic pain or terminal/chronic illness
- Social isolation and lack of support
Assessment Approach in General Practice
The RACGP recommends a case-finding approach rather than universal screening, with GPs remaining alert for patients with higher risk profiles. Assessment should include:
- Direct questioning about suicidal thoughts, plans, intent, and access to means
- Evaluation of both risk factors and protective factors (social connectedness, sense of purpose, children/dependents, problem-solving ability)
- Structured clinical judgement rather than reliance on checklists alone
Contact with primary care is common in the weeks before suicide, so GPs are well-positioned for early identification.
