Self harm and suicide Flashcards
Suicide and self harm exist as a spectrum
Risky behaviours –> ‘life weariness’ –> Death wishes –> suicidal thoughts/plans –> suicidal behaviours –> completed suicide
Epidemiology of suicide
1% lifetime risk –> 8/100,000/yr in the UK
5th cause of life years lost but big international variance
High proportion have contact with health care professionals in month before death
More common in high and low IQ people
Epidemiology of Deliberate self harm
310/100,000/yr –> 170,000 medical presentations
1-2% of patient with DSH completed suicide in the next year –> but risk prediction v. difficult
Evidence that brief psychotheraputic interventions can be useful in patients without psychiatric disorder
Psychiatric assessment after DSH
Patient must be awake –> should be somewhere private
Be patient and assess the risk factors to distinguish acute and chronic risk
Risk factors specific to suicide attempt
Violent method or major overdose
Evidence of planning - Regret over failure
Attempts to conceal planning or aftermath
Honest belief and hope to die - continued active intent
Demographic Risk factors
Male gender –> living alone and recently widowed, divorced/separated
Older, unempolyed
Certain professions –> Farmers or doctors
Clinical/medical risk factors
Psychiatric disorder –> depression/psychosis, personality disorder
Previous or recent attempts, substance misuse
Medical illness –> particularly chronic, painful conditions
Management of DSH in the emergency setting
Admission with or without section
Refer –> community mental health/home treatment team
Drug and alcohol services
Brief psychotherapy by DSH team – ‘Crisis cards’
Good emergency care can reduce chance of repetition
Consent in treating DSH/Suicide
Mental health act allows for mental disorders to be treated but not physical –> a patient has the right to refuse treatment if they retain capacity –> if capacity impaired can treat for their best interests
Reasons patients lose capacity
Unconsciousness
Any mental disturbance or disability which prevents them: retaining/understanding information, believing it, weighing choices –> NO one else can consent for a patient (except a parent under the age of 16)
Suicide prevention
Proper management post self harm is one of few areas where suicide rates may be effected –> but suicide rates are mainly effected by socioeconomic circumstance and availability of methods
School based programs helped a bit (down by 1.5%)
Media guidlines and hot lines
Antidepressants and suicidal thoughts
Hammad 2006 meta-analysis found that antidepressants moderately increase the risk of suicide
Suicide and days of the week
Greatest on mondays, particularly in women
Adolescent self harm
25,000 presentations/yr –> 10% to hospials
7-14% of adolescents will DSH at some point, and 20-45% report having had suicidal thoughts
Prevalence much higher in females –> highest at 15-24 and 35-45
Hospital presentations of DSH
Only represent about 22.9% of cases
90% of cases which get to hospital are poisoning
Numbers are increasing from 2000
