Suicide and attempted suicide are significant causes of morbidity and mortality.
- Women attempt suicide 1.5 times more often than men. Men complete suicide 3 times more often than women.
- In the United States: predominant age: adolescence through age 34 years (2nd leading cause of death), 12th leading cause of death overall per 2020 Centers for Disease Control and Prevention report (latest available)
- Worldwide, suicide is the 4th leading cause of death among youths (ages 15 to 29 years), 15th leading cause of death per World Health Organization reports from 2020.
- Be alert to a combination of increased emotional disturbance and access to the potential tools to cause death.
- 80% who complete suicide had a previous attempt.
- 90% who complete suicide meet Diagnostic and Statistical Manual of Mental Disorders criteria for major depression, bipolar disorder, anorexia, panic, and personality disorders. Schizophrenia or acute onset of psychosis are also risk factors due to command hallucinations and hopelessness that can accompany these states. Delusional disorders—specifically persecutory and somatic delusions—are associated with increased depression accompanying those symptoms (1).
- Substance use and withdrawal
- Family history of suicide
- Physical illness, including head injury (associated with 20% increased risk of death by suicide)
- For teenagers: not feeling “connected” to their peers or family; being bullied; gender identity issues; poor grades
- Among veterans: childhood abuse; major depression; multiple psychiatric hospitalizations are the best predictors of suicide risk (2).
- Access to lethal means: firearms, poisons; including prescription and nonprescription drugs; pesticides
- Educate patients about 24/7 resources.
- Screen for risk: Use screening instruments but providers need to keep in mind the risks particular to each patient and might not be captured in some screening tools (see “Risk Factors”) and providers, own biases in assessing risk. Screening instruments include the Patient Health Questionnaire-2 (PHQ-2), the PHQ-9, the Columbia Suicide Severity Rating Scale, Beck Scale for Suicide Ideation, Linehan Reasons for Living Inventory, and Motto Risk Estimator for Suicide.
- Treat underlying mental and medical illnesses and substance abuse. Continuity of care has been identified as a key protective factor. It is among the strategies in the “Perfect Depression Care” initiative out of a Detroit area HMO, and was associated with a 77% decrease in suicide rate.
- Screen for possession of means of harm, including prescribed/unprescribed drugs, poisons, and firearms
- Create a safety plan for patients at risk patients and their families, including how to access 24/7 emergency care.
- Public education about how to help others access emergency psychiatric care. Suicidal people may initially confide in those they trust outside health care.
- For the military: multiple resources: https://www.realwarriors.net. Suggested treatments include cognitive restructuring techniques (that their experience with adversity can be a source of strength) and help with problem-solving (so the service member does not feel like a “burden”), therapeutic martial arts training, focus on vets helping others: “Power of 1” initiative (any “one” helpful contact could save a life).
