Self harm and suicide Flashcards
What is the definition of deliberate self harm?
Deliberate self-harm (DSH) refers to an intentional act of self-poisoning or self-injury, irrespective of the motivation or apparent purpose of the act. It is usually an expression of
emotional distress
Methods of self injury
Cutting
Burning
Hanging
Stabbing
Swallowing objects
Shooting
Jumping
Methods of self-poisoning
Medication (prescribed or OTC)
Illicit drugs
Household substances
Plant material

DSH Largely Comes Via Self-Poisoning
Divorced/single/living alone
Severe life stressors
Harmful drug/alcohol use

Chronic physical health problems
Violence (domestic) or childhood maltreatment
Socioeconomic disadvantage
Psychiatric illness, e.g. depression, psychosis
Epidemiology of DSH
DSH affects 2 in 1000 people in the UK.
It is more common in ♀ at a ratio of 1.5:1, but this varies greatly with age.
164
DSH is more common in adolescents and young adults. Incidence peaks
in ♀ aged 15–19 years, and in ♂ aged 20–24 years.
It is 20–30 times more common than suicide.
The rate of suicide in people who have self-harmed increases to between 50–100 times
greater than that of the suicide rate in the general population.
Clinical features of self harm
DSH can take the form of:
Self-poisoning in the form of overdose.
Self-injury in the form of cutting, burning, slashing.
In the UK, 90% of DSH cases are a result of drug overdose. Commonly ingested
medications are non-opioid analgesics including paracetamol and salicylates (aspirin),
anxiolytics (including benzodiazepines), and antidepressants (self-harmers are commonly
depressed).
10% of DSH cases are due to self-injury. Common locations for cuts with razors or glass are
the forearms and wrists
Other less common methods of self-injury include jumping in front of moving vehicles or
from great heights and attempting to drown oneself (Fig. 9.1.1).
About half the men and a quarter of women who self-harm have taken alcohol in the 6
hours prior to the act, indicating that alcohol is a key risk factor.
The two commonest complications of DSH: (1) Permanent scarring of skin and damage to
tendons and nerves as a result of self-cutting. (2) Acute liver failure due to paracetamol
overdose.
How does self harm differ from suicide?
Act with intent to hurt self
Includes cutting, overdose (less lethal)
No intention to kill self
Self harm is more common in girls
Act with intent to kill self
Includes jumping from height, hanging (more lethal)
Intention includes desire to be dead (?how to check for intent)
Suicide is more in boys/males
History for self-harm
What were their intentions before and during the act? (intention)
Does the patient now wish to die? (suicidal ideation)
What are the current problems in their life? (severe life stressors)
Is there a psychiatric disorder? (psychiatric illness)
Collateral history from relatives, friends or the GP is important.
Motives behind deliberate self-harm
DRIPS
Death wish: genuine wish to die.
Relief: seeking unconsciousness or pain as a means of temporary relief and escape from
problems.
Influencing others: trying to influence another person to change their views or behaviour
(e.g. making a spouse feel guilty for not caring enough).
Punishment: to punish oneself.
Seeking attention: trying to get help or seek attention (expression of emotional distress).
Mental health issues that cause self harm
Coping (Defence mechanisms)
Emotional dysregulation/Behavioural
Impulsive/Influenced by impulsivity (ADHD)
Personality traits (conduct disorder, borderline)
Depression
Psychosis
Eating disorder
Self harm in low mood
Pervasive
Persistent – at least 2 weeks
Unresponsive to circumstances
Anhedonia
Helplessness, hopelessness, worthlessness
Sleep
Appetite
Depression in young people
Recently becoming less active
withdrawn
Less time on TV/Play
Decreased or increased sleep
Decreased appetite
Somatic complaints
Irritability
Difficulty concentrating
Regression

Causes of Self harm which can become dangerous
Intent – planning ahead/timing/letter/obligations
Lethality – multiple methods
Comorbid mental illnesses
Depression
Psychosis - hallucinations
Past history of serious self harm
Family history of suicide
Substance abuse
Link between hearing voices and self harm
Hallucinations- what are they?
Hallucinations can be normal: Can you give examples?
Commanding voices
Thought Echo
Discussing auditory hallucinations
Is there any associated hallucinatory behaviour?
Is there any loss of touch with reality (not delirium)
Is there any family history of psychosis and suicide?
MSE for self harm
Obvious self-inflicted injuries may be seen. The patient may be tearful or exhibit
signs of neglect. Behaviour may reflect an underlying mental disorder
(depression, schizophrenia).
Thoughts may include feelings of guilt, worthlessness or helplessness.
Hallucinations may be present in cases of schizophrenia and depression with
psychosis where DSH is triggered by command hallucinations.
Concentration is often impaired and insight can vary
Investigations for DSH
Bloods including: Paracetamol levels (accurate between 4 and 15 hours after
ingestion), salicylate levels if suspected overdose, U&Es (renal function), LFTs
and clotting (synthetic hepatic function).
Urinalysis for possible toxicological analysis.
CT head if an intracranial cause for altered consciousness is suspected (in selfpoisoning).
Lumbar puncture if intracranial infection (e.g. meningitis) suspected (in selfpoisoning).
DDs for DSH
Biological: Includes treating any overdose with the appropriate antidote (see Key facts) and
suturing (and anti-tetanus treatment if appropriate) for deep lacerations.
Psychological: Includes counselling and CBT for underlying depressive illness.
Psychodynamic psychotherapy may be appropriate if the individual has a personality
disorder. However, this is a long term treatment and needs appropriate assessment.
Social: Social services input and voluntary organizations (e.g. the Samaritans, Mind).
General points for DSH
Risk assessment is mandatory as there is an immediate risk of suicide and risk of repeat
acts of self-harm. Need for hospitalization should be assessed ± use of the MHA Section 2.
There is often involvement of the Crisis team in the community as an alternative to hospital
admission (see Chapter 1, Introduction to psychiatry).
If the patient refuses medical treatment for the consequences of self-harm (e.g. acute liver
failure, deep lacerations) a mental capacity assessment will be required.
Treat any underlying psychiatric illness with medication and/or psychological therapies.
Consider safety in overdose of antidepressants for co-morbid depression. TCAs are most
dangerous as they can cause arrhythmias and convulsions in overdose.
Psychosocial assessment is required. Many patients have personal, relationship or social
problems for which they can be offered help (e.g. counselling and social service input).
Ensure that the patient is followed up within 48 hours of discharge
Principles behind managing deliberate self harm
Acute management: Specific antidotes, suturing, surgical input for complex wounds
Manage high suicide risk: Full risk assessment, consider inpatient psychiatric assessment (+MHA)
Treat any psychiatric disorder: Antidepressants or CBT for depression
Enable patient to resolve any difficulties that led to the DSH: Manage psychosocial needs, refer to drug/ alcohol services if appropriate, offer financial and occupational rehab advice
Enable patient to manage future crises: Follow up, offer written and verbal info, remove access to means of DSH
