Assessment of suicide risk


Assessment of suicide risk

uicide risk assessment in practice

Suicide risk assessment is ethically complex: the concept of "imminent suicide" (implying the foreseeability of an inherently unpredictable act) is a legal construct in a clinical guise, which can be used to justify rationing of emergency psychiatric resources or intrusion into patients' civil liberties. [cite journal|last=Simon|first=Robert|year=2006|title=Imminent Suicide: The Illusion of Short-Term Prediction|journal=Suicide & Life-threatening Behavior|volume=36|issue=3|pages=296-302|url=http://proquest.umi.com.elibrary.jcu.edu.au/pqdweb?did=1066465081&sid=3&Fmt=3&clientId=20960&RQT=309&VName=PQD|accessdate=2008-08-10] Accurate and legally defensible risk assessment requires that a clinician integrates clinical judgement with the latest evidence-based practice, [cite journal|last=Simon|first=Robert |year=2006|title=Suicide risk assessment: is clinical experience enough?|journal=Journal of the American Academy of Psychiatry and the Law|volume=34|issue=3|pages=276-8|pmid=17032949|accessdate=2008-08-03] although accurate prediction of low base rate events such as suicide is inherently difficult and prone to false positives. There are risks and disadvantages to both over-estimation and under-estimation of suicide risk. Over-sensitivity to risk can have undesirable consequences, including inappropriate deprivation of patients’ rights and squandering of scarce clinical resources. On the other hand, underestimating suicidality as a result of a dismissive attitude or lack of clinical skill jeopardizes patient safety and risks clinician liability. [cite journal|last=Bryan |first=Craig |coauthors=Rudd David |year=2006|title=Advances in the Assessment of Suicide Risk|journal=Journal of Clinical Psychology|volume=62|issue=2|pages=185-200|doi=10.1002/jclp.20222|accessdate=2008-08-03]

Key areas to be assessed include the person's predisposition to suicidal behavior; identifiable precipitant or stressors; the patient’s symptomatic presentation; presence of hopelessness; nature of suicidal thinking; previous suicidal behavior; impulsivity and self-control; and protectivefactors.Suicide risk assessment should distinguish between and risk: acute risk might be raised because of recent changes in the person's circumstances or mental state, while chronic risk is determined by a diagnosis of a mental illness, and social and demographic factors. Bryan and Rudd (2006) suggest a model in which risk is categorized into one of four categories: Baseline, Acute, Chronic high risk, and Chronic high risk with acute exacerbation. [cite journal|last=Bryan |first=Craig |coauthors=Rudd David |year=2006|title=Advances in the Assessment of Suicide Risk|journal=Journal of Clinical Psychology|volume=62|issue=2|pages=185-200|doi=10.1002/jclp.20222|accessdate=2008-08-03] Risk level can also be described as Nonexistent, Mild, Moderate, Severe, or Extreme, and the clinical response can be determined accordingly.

Demographic factors

Age

In the USA, the peak age for suicide is early adulthood, with a smaller peak of incidence in the elderly. [Jacobs et al (2003) VI. Review and Synthesis of Available Evidence]

Gender

In the USA, suicide is around 4.5 times more common in men than in women. [Jacobs et al (2003) VI. Review and Synthesis of Available Evidence]

Ethnicity and culture

In the USA, white Americans and Native Americans have the highest suicide rates, black Americans have intermediate rates and Hispanic people have the lowest rates of suicide. However, Native American males in the 15-24 age group have a dramatically higher suicide rate than any other group. [Jacobs et al (2003) VI. Review and Synthesis of Available Evidence] A similar pattern is seen in Australia, where Aboriginal people (especially young Aboriginal men) have a much higher rate of suicide than white Australians, a difference which is atttributed to social marginalization, trans-generational trauma, and high rates of alcoholism.

Marital status

Married men and unmarried women are at highest risk. [cite journal|last=Bryan |first=Craig |coauthors=Rudd David |year=2006|title=Advances in the Assessment of Suicide Risk|journal=Journal of Clinical Psychology|volume=62|issue=2|pages=185-200|doi=10.1002/jclp.20222|accessdate=2008-08-03]

exual orientation

There is evidence of elevated suicide risk among Gay, Lesbian, Bisexual, and Transgendered individuals; homosexualmen are at particularly high risk. [cite journal|last=Bryan |first=Craig |coauthors=Rudd David |year=2006|title=Advances in the Assessment of Suicide Risk|journal=Journal of Clinical Psychology|volume=62|issue=2|pages=185-200|doi=10.1002/jclp.20222|accessdate=2008-08-03]

Biographical and historical factors

The literature on this subject consistently shows that a family history of committed suicide in first-degree relatives, adverse childhood experiences (parental loss and emotional, physical and sexual abuse), and adverse life situations (unemployment, isolation and acute psychosocial stressors) are associated with suicide risk. [cite journal|last=Zoltán Rihmer|first=Zoltán |year=2007|title=Suicide Risk in Mood Disorders|journal=Current opinion in psychiatry|volume=20|issue=1|pages=17-22|doi=?|accessdate=2008-08-02]

Recent life events can act as precipitants. Significant interpersonal loss and family instability, such as bereavement, poor relationship with family, domestic partner violence, separation, and divorce have all been identified as risk factors. Financial stress, unemployment, and a drop in socioeconomic status can also be triggers for a suicidal crisis. This is also the case for a range of acute and chronic health problems, such as pain syndromes, or diagnoses of conditions like HIV or cancer. [cite journal|last=Bryan |first=Craig |coauthors=Rudd David |year=2006|title=Advances in the Assessment of Suicide Risk|journal=Journal of Clinical Psychology|volume=62|issue=2|pages=185-200|doi=10.1002/jclp.20222|accessdate=2008-08-03] [Jacobs et al (2003) II. Assessment of Patients With Suicidal Behaviors]

Mental state

Certain clinical mental state features are predictive of suicide. An affective state of hopelessness, in other words a sense that nothing will ever get better, is a powerful predictive feature. [cite journal|last=Bryan |first=Craig |coauthors=Rudd David |year=2006|title=Advances in the Assessment of Suicide Risk|journal=Journal of Clinical Psychology|volume=62|issue=2|pages=185-200|doi=10.1002/jclp.20222|accessdate=2008-08-03] High risk is also associated with a state of severe anger and hostility, or with agitation, anxiety, fearfulness, or apprehension. [NSW Department of Health 2004 p 20] [Jacobs et al (2003) II. Assessment of Patients With Suicidal Behaviors] Specific psychotic symptoms, such as grandiose delusions, delusions of thought insertion, and mind reading, are thought to indicate a higher likelihood of suicidal behavior. [cite journal|last=Simon|first=Robert |year=2006|title=Suicide risk assessment: is clinical experience enough?|journal=Journal of the American Academy of Psychiatry and the Law|volume=34|issue=3|pages=276-8|pmid=17032949|accessdate=2008-08-03] Command hallucinations are often considered indicative of suicide risk, but the empirical evidence for this is equivocal. [NSW Department of Health 2004 p 20] [cite journal|last=Montross |first=Lori |coauthors=Zisook Sidney, Kasckow John|year=2005|title=Suicide Among Patients with Schizophrenia: A Consideration of Risk and Protective Factors|journal=Annals of Clinical Psychiatry|volume=17|issue=3|pages=173 - 182|doi=10.1080/10401230591002156|accessdate=2008-08-10]

uicidal ideation

"Suicidal ideation" refers to the thoughts that a person has about suicide. Assessment of suicidal ideation includes assessment of the extent of preoccupation with thoughts of suicide (for example continuous or specific thoughts), specific plans, and the person's reasons and motivation to attempt suicide. [NSW Department of Health (2004) p 20]

Planning

Assessment of suicide risk includes an assessment of the degree of planning, the potential or perceived lethality of the suicide method that the person is considering, and whether the person has access to the means to carry out these plans (such as access to a firearm). A suicide plan may include the following elements: timing, availability of method, setting, and actions made towards carrying out the plan (such as obtaining medicines, poisons, rope or a weapon) , choosing and inspecting a setting, and rehearsing the plan). The more detailed and specific the suicide plan, the greater will be the level of risk. The presence of a suicide note generally suggests more premeditation and greater suicidal intent. The assessment would always include an exploration of the timing and content of any suicide note and a discussion of its meaning with the person who wrote it. [NSW Department of Health (2004) p 20] [Jacobs et al (2003) II. Assessment of Patients With Suicidal Behaviors]

Motivation to die

Suicide risk assessment includes an assessment of the person's reasons for wanting to commit suicide. This includes recent triggering events, and beliefs about death.Fact|date=August 2008

Other motivations for suicide

Suicide is not motivated only by a wish to die. Other motivations for suicide include an expression of anger or a desire for revenge on those who have hurt the person.Fact|date=August 2008

Reasons to live

Balanced against reasons to die are the suicidal person's reasons to live, and an assessment would include an enquiry into the person's reasons for living and plans for the future. [Jacobs et al (2003) II. Assessment of Patients With Suicidal Behaviors]

Past suicidal acts

People who commit suicide often have a history of past self harm or suicide attempts. The level of suicidality is predicted by the nature of past suicide attempts, taking into consideration factors such as lethality, planning, and efforts made to conceal the attempt.Fact|date=August 2008

uicide risk and mental illness

All major mental disorders carry an increased risk of suicide. [Gelder et al (2003) p 1037]

Anorexia nervosa has a particularly strong association with suicide: the rate of suicide is forty times greater than the general population. [Gelder et al (2003) p 1037] The lifetime risk of suicide was 18% in one study, and in another study 27% of all deaths related to anorexia nervosa were due to suicide. [Gelder et al (2003) p 847]

The long-term suicide rate for people with schizophrenia was estimated to be between 14 and 22%, but a more recent meta-analysis has estimated that 4.9% of schizophrenics will commit suicide during their lifetimes, usually near the illness onset. [Gelder et al (2003) p614] [cite journal|last=Palmer|first=Brian |coauthors=Pankratz Shane, Bostwick John |year=2005|title=The Lifetime Risk of Suicide in Schizophrenia. A Reexamination|journal=Archives of General Psychiatry|volume=62|pages=247-253|accessdate=2008-08-03] Risk factors for suicide among people with schizophrenia include a history of previous suicide attempts, the degree of illness severity, comorbid depression or post-psychotic depression, social isolation, and male gender. The risk is higher for the paranoid subtype of schizophrenia, and is highest in the time immediately after discharge from hospital. [cite journal|last=Montross |first=Lori |coauthors=Zisook Sidney, Kasckow John|year=2005|title=Suicide Among Patients with Schizophrenia: A Consideration of Risk and Protective Factors|journal=Annals of Clinical Psychiatry|volume=17|issue=3|pages=173 - 182|doi=10.1080/10401230591002156|accessdate=2008-08-10]

While the lifetime suicide risk for mood disorders in general is around 1%, long-term follow-up studies of people who have been hospitalized for severe depression show a suicide risk of up to 13%. [cite journal|last=Bryan |first=Craig |coauthors=Rudd David |year=2006|title=Advances in the Assessment of Suicide Risk|journal=Journal of Clinical Psychology|volume=62|issue=2|pages=185-200|doi=10.1002/jclp.20222|accessdate=2008-08-03] People with severe depression are 20 times more likely and people with bipolar disorder are 15 times more likely to die from suicide than members of the general population. [Gelder et al (2003) p 722] Depressed people with agitation, severe insomnia, anxiety symptoms, and co-morbid anxiety disorders are particularly at-risk. [Fawcett J., Acute risk factors for suicide: anxiety severity as a treatment modifiable risk factor. Chapter 4 in Tatarelli et al (eds) (2007)]

People with a diagnosis of a personality disorder, particularly borderline, antisocial or narcissistic personality disorders, are at a high risk of suicide. In this group, elevated suicide risk is associated with younger age, comorbid drug addiction and major mood disorders, a history of childhood sexual abuse, impulsive and antisocial personality traits, and recent reduction of psychiatric care, such as recent discharge from hospital. While some people with personality disorders may make manipulative or contingent suicide threats, the threat is likely to be non-contingent when the person is silent, passive, withdrawn, hopeless, and making few demands. [cite journal|last=Lambert|first=Michael|title=Suicide risk assessment and management: focus on personality disorders|journal=Current opinion in psychiatry|volume=16|issue=1|pages=71-76|doi=?|accessdate=2008-08-02]

A history of alcohol abuse and alcohol dependence is common among people who commit suicide, and alcohol intoxication at the time of the suicide attempt is a common pattern. [Jacobs et al (2003) B-II-E]
