Deliberate Self-Harm (DSH)
• Definition:
o Any act of self-poisoning or self-injury, regardless of intent.
o May be non-suicidal (emotional regulation, cry for help) or suicidal (intent to die).
• Assessment essentials:
o Determine intent: was it an attempt to end life or to relieve distress?
o Evaluate lethality: method used, planning, precautions against discovery.
o Access to means: ongoing availability of pills, sharp objects, firearms.
• Psychiatric comorbidity:
o High association with mood disorders, personality disorders (especially borderline), substance misuse.
Suicide Risk
• Key risk factors (SAD PERSONS mnemonic):
o Sex (male higher completion risk)
o Age (>45 men, >55 women)
o Depression or hopelessness
o Previous attempts
o Ethanol/substance abuse
o Rational thinking loss (psychosis)
o Social supports lacking
o Organised plan
o No spouse (single/divorced/widowed)
o Sickness (chronic illness)
• High-risk markers:
o Recent serious attempt or high-lethality method.
o Ongoing strong suicidal ideation, expressed plan.
o Active psychosis, severe depression, recent major losses.
Management
• Immediate priorities:
o Medical stabilisation (if overdose, physical injury).
o Remove access to lethal means.
o Maintain safe environment.
• Psychiatric management:
o Risk assessment: structured, document thoroughly.
o Safety planning: identify warning signs, coping strategies, contacts for crisis.
o Crisis team or community support for moderate risk.
• Admission indications:
o Persistent high risk of suicide.
o Severe psychiatric illness needing intensive treatment.
o Lack of social support, unable to ensure safety at home.
Extra Revision Pearls
• Men are more likely to die by suicide, but women make more attempts.
• Previous suicide attempt is the strongest single predictor of future completed suicide.
• SSRIs may increase suicidal ideation in young adults early in treatment — close monitoring is crucial.
• In borderline personality disorder, self-harm is often non-suicidal but still requires careful assessment.
• Always evaluate protective factors: children, family ties, religious beliefs, therapeutic alliance.
