Preventing and Responding to Suicide: Psychiatric-Mental Health Nursing

Preventing and Responding to Suicide

Introduction to Suicide

Suicide is a complex and multifaceted phenomenon that poses significant challenges for mental health professionals. Understanding its definition, prevalence, and associated risk factors is essential for effective prevention and intervention.

• Definition of Suicide: Self-inflicted injury accompanied by an intent to die from the injury.

• Prevalence: Approximately 45,000 people die by suicide annually in the United States, with 70% being White males.

• Gender Differences: Men commit suicide 3.53 times more often than women, but women have a higher rate of suicide attempts.

• Methods: Firearms account for 51% of all suicides (2016 data).

• Age Group: Suicide is a leading cause of death for individuals aged 10–34.

• Suicidal Ideation: Thoughts of suicide.

• Suicide Attempt: Self-directed injury with an intent to die that does not result in death.

Populations at High Risk for Suicide

Demographic and Social Factors

Certain populations exhibit higher rates of suicide due to a combination of biological, psychological, sociological, cultural, and spiritual factors.

• White males have the highest suicide completion rates.

• Youth and young adults (ages 10–34) are at increased risk.

• LGBTQ individuals face higher lifetime prevalence rates (11–20%) compared to heterosexual individuals (4%).

• Military personnel and veterans are at greater risk, especially Caucasian males under 25 and junior enlisted ranks.

• Individuals in incarceration have a high risk, particularly within 24 hours of incarceration or after traumatic events.

• Individuals with chronic or terminal illness (e.g., nervous system diseases, cancer, HIV/AIDS, chronic pain).

• Older, single Caucasian men experience high rates due to isolation and chronic illness.

• Individuals with trauma history (e.g., abuse, interpersonal violence).

• Native American youth and Chinese women are at elevated risk due to cultural and historical factors.

Domains Affecting Suicide Risk

Biological, Psychological, Sociological, Cultural, and Spiritual Domains

Suicide risk is influenced by multiple domains, each contributing unique factors to an individual's vulnerability.

• Biological Domain:

  • Brain regions involved: thalamus, cingulate cortex, prefrontal cortex, cerebellum, parahippocampal gyrus.

  • Decreased central serotonin activity in the ventromedial prefrontal cortex.

  • Genetic factors (polyphenotype concept).

  • Low vitamin D levels may be associated with increased suicide risk.

• Psychological Domain:

  • Depression, anxiety, impulsivity, substance use disorders.

  • Personality disorders (impulsive, aggressive behavior patterns).

  • Major depression or bipolar disorder with severe anxiety and substance abuse increases risk.

  • Adolescents: impulsivity, lack of coping experience, family history, loss, abuse, bullying.

• Sociological Domain:

  • Social isolation, loss of relationships, trauma history.

  • Durkheim’s types of suicide:

    • Egoistic: Individual isolated from others.

    • Altruistic: Loyalty to or identification with societal rules.

    • Anomic: Estrangement from society, role changes.

• Cultural Domain:

  • Role expectations, historical trauma, family and societal pressures.

  • Protective factors: cultural values, sense of belonging, practical support.

  • Examples: Native American youth (historical trauma), Chinese women (role expectations, pesticide ingestion).

• Spiritual Domain:

  • Religious beliefs may prohibit suicide and restrict burial practices.

  • Spirituality can provide hope and protective measures.

Theories and Models of Suicide

Durkheim’s Types of Suicide

Emile Durkheim classified suicide into three types based on social integration and regulation:

• Egoistic: Resulting from social isolation.

• Altruistic: Due to excessive integration into society.

• Anomic: Caused by breakdown of social norms.

Shneidman’s Ten Commonalities of Suicide

Edwin Shneidman identified ten psychological commonalities in suicide:

• Seeking a solution

• Cessation of consciousness

• Intolerable psychological pain

• Frustrated psychological needs

• Hopelessness–helplessness

• Ambivalence

• Constriction

• Escape

• Communication of intention

• Lifelong coping patterns

Joiner’s Interpersonal Theory of Suicide

This theory posits that suicide risk increases when three factors are present:

• Thwarted belongingness: Feeling disconnected from others.

• Perceived burdensomeness: Belief that one is a burden to others.

• Acquired capability: Increased tolerance for pain and fear of death.

Suicidal Behaviors and Risk Factors

Warning Signs and Risk Factors

Recognizing behavioral, psychological, and social warning signs is critical for early intervention.

• Changes in sleep patterns, appetite, energy

• Loss of interest, hopelessness, withdrawal

• Impulsivity, agitation, restlessness

• Family history of suicide or mental illness

• Substance abuse, chronic illness, trauma history

• Recent losses, conflicts, or abuse

• Lack of social support, connectedness, or access to services

• Feelings of shame, isolation, or failure

Protective Measures Against Suicide

Internal and External Protective Factors

Protective factors help individuals feel hopeful and worthy, reducing suicide risk.

• Personal, social, cultural, and spiritual beliefs

• Valued relationships

• Restricted access to means of suicide

• Supportive relationships and coping style

• Reasons for living and spiritual connection

Assessment and Severity of Suicide Risk

Suicide Risk Assessment

Assessment should be conducted in a safe, quiet environment and include explicit questions about suicidal thoughts, plans, and means.

• Ask about intent, means, and concentration of thoughts on suicide.

• Recognize warning signs and provide immediate assistance if necessary.

• Use standardized scales and indices (e.g., Level of Suicide Severity Index).

Level of Suicide Severity Index

This index categorizes suicidal severity into stages:

• Stage I: No thoughts or mild, fleeting thoughts dismissed quickly.

• Stage II: Moderate thoughts; suicide considered as a problem-solving option.

• Stage III: Advanced thoughts; individual has a plan and method.

• Stage IV: Moribund; no protective measures, intent not disclosed.

Interventions vary by stage, from reducing anxiety and depression to hospitalization and intensive care.

Interprofessional Approach to Suicide Prevention

Collaborative Care

Effective suicide prevention requires a multidisciplinary approach:

• Community suicide hotlines and crisis mobile teams

• Law enforcement for imminent risk

• Comprehensive evaluation (physical, psychological)

• Psychotropic medications and monitoring

• Electroconvulsive therapy (ECT) for severe cases

• Psychotherapy (CBT, psychodynamic, interpersonal, dialectical behavioral therapy)

Comprehensive Suicide Prevention Strategies

Key Elements

• Identify and assist persons at risk

• Increase help-seeking behavior

• Ensure access to mental healthcare

• Support safe care transitions

• Respond effectively to individuals in crisis

• Provide immediate and long-term postvention

• Reduce access to means of suicide

• Enhance life skills and resilience

• Promote social support and connectedness

Safety Planning Interventions

Evidence-Based Safety Planning

Safety planning is a collaborative intervention empowering patients to manage suicidal thoughts and reduce risk.

• Identify warning signs of crisis

• Develop coping strategies

• List people, settings, and activities for distraction

• Provide contacts for help (people, agencies)

• Make the environment safe

Nursing Care for Patients at Risk of Suicide

Diagnosis and Planning

Distinguish between suicide and self-directed violence. Prioritize risk for suicide and self-harm in care planning.

• Hospitalization may be necessary until impulse control is regained.

• Care plans should be adjusted during recovery and rehabilitation.

• Facilitate understanding of hopelessness and triggers.

Implementation of Interventions

Interventions should focus on reducing isolation, developing therapeutic alliances, and facilitating group therapy.

• Directly ask about suicidal ideation

• Listen and encourage sharing of feelings

• Be nonjudgmental and supportive

• Remove means of self-harm

• Call for help if patient is imminently suicidal

• Avoid harmful actions (judging, lecturing, false reassurance)

Stages of Nursing Interventions by Suicide Risk Severity

Nursing interventions should be tailored to the patient's stage of suicide risk severity.

Stage	Patient Perceptions	Nursing Interventions
I	No suicidal thoughts or fleeting, easily dismissed thoughts	Monitor in public areas, encourage expression, provide support
II	Moderate thoughts, suicide considered as an option	Reduce anxiety, depression, worry; professional evaluation
III	Advanced thoughts, plan and method present	Thorough multidisciplinary evaluation, possible hospitalization
IV	Moribund, no protective measures, intent not disclosed	Intensive care, strict observation, immediate intervention

Patient Education and Postvention

Education and Support

• Help patients identify precipitating factors and problem-solving strategies

• Use stress-reducing activities (exercise, socializing, hobbies)

• Collaborative Assessment and Management of Suicidality (CAMS) approach

Interventions Following Suicide

• Support family and friends experiencing shock, anger, guilt

• Listen without judgment

• Refer for short-term therapy

Evaluation of Care

Assessing Outcomes

• Evaluate whether interventions yielded expected results

• Document all care, assessment, risk factors, protective measures, and patient status

• Empower patient participation in care

Summary: From Suffering to Hope

Suicidal ideation is a complex problem requiring courage to address. Building a therapeutic alliance and assisting patients in problem-solving are essential steps toward hope and recovery.
