Advances in science, advocacy, and stigma reduction have led to an evolution in all of the terminology related to suicide, including those concepts already defined above:
Suicidal intent: Intention to end one's life through the act of suicidal behavior
Suicide attempt: A nonfatal, potentially injurious behavior directed against the self with an intent to die as a result of the behavior
Suicide attempt survivors: People with their own personal experience with suicidal thoughts or attempt(s); often important in the advocacy movement of suicide prevention; suicide attempt survivors sometimes join forces with other advocates (eg, Loss Survivors)
Suicide loss survivor or suicide bereaved: Family members or friends of a person who died by suicide
Three other important changes in suicide terminology have also made it into the professional lexicon:
Died by suicide: This recommended language is preferred over the phrase “committed suicide.” Other plain language is acceptable as well (eg, “killed himself,” “ended her life,” “took his life”).
Nonsuicidal self-injury (NSSI) Nonsuicidal Self-Injury (NSSI) Nonsuicidal self-injury is a self-inflicted act that causes pain or superficial damage but is not intended to cause death. Although the methods used sometimes overlap with those of suicide attempts... read more and self-injurious behavior (SIB): These behaviors are defined as deliberately injuring oneself without suicidal intent; self-cutting is the most common form, but burning, scratching, hitting, and intentionally preventing wounds from healing are other forms. While the behavior itself is without suicidal intent, people who have a pattern of NSSI have been found to have a higher risk of suicide in the long term.
Suicidality: This term is frequently used in clinical settings between professionals to refer to the spectrum of possible suicidal experiences; it does not specify ideation, attempt, chronic/recurrent, or singular event. In many instances, communication can be more effective and clear if one articulates the actual issue at hand, such as ideation or attempt, and include any relevant details.

Epidemiology of Suicidal Behavior
Statistics on suicidal behavior are based mainly on death certificates and inquest reports and underestimate the true incidence. To provide more reliable information in the United States, the Centers for Disease Control and Prevention (CDC) established a state-based system that collects facts about each violent incident from various sources to provide a clearer understanding of the causes of violent deaths (homicides and suicides), the National Violent Death Reporting System (NVDRS). The NVDRS is now in place in all 50 states, the District of Columbia, and Puerto Rico.
In the United States, suicide is the 10th leading cause of death.
The age group with the highest suicide rate is now people aged 45 to 64 years, resulting from a recent significant increase. Why this rate has increased is unknown; however, the following factors may have contributed:
Years ago, as teenagers, this group had a higher rate of depression Depressive Disorders Depressive disorders are characterized by sadness severe enough or persistent enough to interfere with function and often by decreased interest or pleasure in activities. Exact cause is unknown... read more than older groups, and researchers predicted that their suicide rate would rise as they aged.
This rate includes the increased number of suicides among military personnel and veterans (20% of suicides are in that group).
This rate may also stem from intersecting influences, including unmet expectations and beliefs of this particular cohort, rise in the availability of lethal means, the opioid crisis, changes in the economy, and the persistent stigma associated with addressing mental health conditions.
The second highest rate of suicide is in people ≥ 75 years.

The number of suicides in men includes suicides among military personnel and veterans, where there is a higher proportion of men to women.
White men account for 7 in every 10 suicides in the United States even though they account for around one third of the population.
In 2019, an estimated 1.4 million American adults made a suicide attempt. About 25 attempts are made for every death that occurs by suicide. Many make repeated attempts. Only 5 to 10% of people who make an attempt eventually die by suicide; however, in older people, 1 in every 4 suicide attempts ends in death. Although more men than women die by suicide, women attempt suicide 2 to 3 times more often than men; among youth and young adults, there may be 100 attempts by girls to every 1 attempt by boys of the same age.
A suicide note is left by about 1 in 6 people who complete suicide. The content may indicate clues regarding the factors that led to the suicide (eg, psychiatric illness, hopelessness, cognitive constriction and narrowing of perceived options for coping, sense of being a burden to others, and sense of isolation). The intersection of these and other life stressors or losses may precipitate suicide.
Suicide contagion refers to a phenomenon in which one suicide seems to beget others in a community, school, or workplace. Highly publicized suicides may have a very wide effect. Affected people are usually those already vulnerable. Humans are social creatures prone to imitation of one another. Youths are more likely to engage in imitation than adults because of their stage of psychologic development and brain development. It is estimated that contagion is a factor in 1 to 5% of all teen suicides.
Contagion can occur by exposure to a peer who attempts or dies by suicide, by widespread media coverage of a celebrity’s suicide, or by graphic and/or sensationalized portrayal of suicide in popular media. Conversely, media coverage with positive messaging about a suicide death can mitigate the risk and/or impact of suicide contagion for vulnerable youth. Positive messaging typically involves portraying mental health struggles as part of life and human health experience with no stigma related to help seeking and treatment. After a suicide has occurred, positive messages in a school or workplace communicate clearly about the tragic loss of a community member and goes on to express support for the grieving community and provides resources for support. In writing or in in-person meetings for debriefing the loss, the language the leader uses to talk about suicide is important. For more detailed information on communication and templates for written communication, please see the After A Suicide Toolkits freely available on the American Foundation for Suicide prevention ( afsp.org ) web site.
Suicide contagion can also spread in schools and workplaces, which are—in some ways—the ideal settings for implementing and following postvention guidelines to prevent future suicides.
Other categories of suicide are extremely rare. These include
"Suicide by cop" (situations in which people act in a way, for example, brandishing a weapon, that prompts law enforcement officers to act with deadly force)
Etiology of Suicidal Behavior
The current scientifically informed view of suicide is that, while complex, suicide is a health-related event that involves a set of genetic, environmental, and psychologic/behavioral factors. psychologic autopsy studies clearly show that in each instance of suicide, decedents were experiencing multiple risk factors for suicide. Research has shown that 85 to 95% of people who die by suicide have a diagnosable mental health condition at the time of their death.

Effectively treating depression with medications and/or some form of psychotherapy is considered an effective way to reduce suicide risk overall.
Other risk factors for suicide include the following:
Most other serious mental health conditions
Previous suicide attempts
Personality disorders (eg, borderline personality disorder)
Impulsivity and aggression
Traumatic childhood experiences
Family history of suicide and/or psychiatric conditions
Use of alcohol, drugs of abuse, and prescription analgesics
Serious or chronic physical health conditions (eg, chronic pain, traumatic brain injury)
Times of loss (eg, death of family or friends)
Relationship conflict (eg, divorce)
Work disruption (eg, unemployment)
Periods of career transition (eg, changing one's military status from active duty to veteran status or retirement)
Financial stress (eg, economic downturns, underemployment)
Bullying (eg, cyberbullying, social rejection, discrimination, humiliation)
Death by suicide is more common among people with a psychiatric illness than among age- and sex-matched controls. (See table Frequency of Mental Health Disorders in Suicide Frequency of Mental Health Disorders in Suicide* .)

Serious physical health conditions, especially those that are chronic and painful, contribute to about 20% of suicides in older patients. Recently diagnosed or new-onset physical health conditions can also increase suicide risk (eg, diabetes, seizure disorder, pain conditions, multiple sclerosis, cancer, infection, HIV/AIDS). These health conditions can directly impact physiologic brain functioning and, thus, increase suicide risk. The psychologic effects of disability, pain, or a new diagnosis of a serious health condition can also increase the risk of suicide.

The genetics of suicide risk are an important area of research and appear to influence suicide risk. While suicide risk can run in families, genes appear to account for only a portion of that risk ( 2 Etiology references Suicide is death caused by an intentional act of self-harm that is designed to be lethal. Suicidal behavior encompasses a spectrum of behavior from suicide attempt and preparatory behaviors... read more ). A family history of suicide, suicide attempts, or psychiatric disorders is associated with an increased risk of suicide.
Genes and environment both matter when it comes to suicide risk. It has been proposed that epigenetic changes (eg, DNA methylation) affecting gene expression could increase or decrease risk for suicide by affecting neurophysiology, cognition, or stress regulation. This means that negative experiences such as trauma and conversely positive experiences such as the social support of psychotherapy can actually change gene expression and significantly affect an individual’s resilience and risk for suicide. This is an area of research that is attempting to determine the roles of epigenetics.
Psychologic traits such as a tendency toward impulsivity, cognitive rigidity, interpersonal rejection sensitivity, or severe neuroticism can also increase risk.

Choice of method for suicide is determined by many things, including cultural factors, availability of means to complete suicide, and the seriousness of intent. (A combination of these factors surely influences the popularity of pesticide poisoning as a common means of suicide in most Asian countries.) Some methods (eg, jumping from heights) make survival virtually impossible, whereas others (eg, drug ingestion) may allow rescue. However, using a method that proves not to be fatal does not necessarily imply that the intent was less serious.
For suicide attempts, drug ingestion is the most common method used. Violent methods, such as shooting and hanging, are uncommon among attempted suicides.
Approximately 50% of completed suicides in the United States are by firearm; men use this method more than women. Women use poisoning more than men. Other methods of suicide include hanging, jumping from a height, drowning, and cutting.
Management of Suicidal Behavior
In 2018, the National Action Alliance for Suicide Prevention (Action Alliance) published guidelines for recommended standards of care for patients at risk for suicide. These include recommendations for screening, suicide risk assessment, and clinical care in primary care, behavioral health, and emergency department settings ( 1 Management references Suicide is death caused by an intentional act of self-harm that is designed to be lethal. Suicidal behavior encompasses a spectrum of behavior from suicide attempt and preparatory behaviors... read more ).
It is important to note that suicide risk is dynamic. Acute risk generally lasts only a short period of time (hours to days). In the majority of suicides, patients had been seen in various health care settings during the period of acute risk, but suicide risk was not detected. Any sound public health strategy to reduce suicide would equip clinicians in all health care settings (even those outside of behavioral health) to actively look for and mitigate any and all suicide-related risks. This can be done by having health care providers
Employ a caring response
Provide brief interventions (eg, safety planning and lethal means counseling)
Communicate with family and close friends of the patient
Refer the patient for appropriate care
Currently, these steps have the strongest evidence for reducing suicide risk and saving lives.
Certain periods of time are known to be associated with an elevated risk of suicide. The period of days to weeks following discharge from the emergency department or psychiatric hospital for patients admitted for suicidal ideation or a suicide attempt is just such a period and, therefore, a prime point of intervention ( 2 Management references Suicide is death caused by an intentional act of self-harm that is designed to be lethal. Suicidal behavior encompasses a spectrum of behavior from suicide attempt and preparatory behaviors... read more ).
A health care practitioner who foresees the imminent likelihood of suicide in a patient is, in most jurisdictions, required to inform an empowered agency to intervene. Failure to do so can result in criminal and civil actions. At-risk patients should not be left alone until they are in a secure environment (often a psychiatric facility). If necessary, those patients should be transported to that secure environment by trained professionals (eg, emergency medical technicians, police officers). Current advocacy efforts in the United States, the United Kingdom, New Zealand, Australia, and elsewhere aim to reform the crisis response system to move toward reliance on a more robust multi-tiered set of mental health resources such as mobile crisis units and comprehensive crisis care and away from their current reliance on emergency departments and law enforcement.
Any suicidal act, regardless of whether it is a gesture or an attempt, must be taken seriously. Every person with a serious self-injury should be evaluated and treated for the physical injury.
If an overdose of a potentially lethal drug is confirmed, immediate steps are taken to administer an antidote and provide supportive treatment (see Poisoning Treatment Poisoning is contact with a substance that results in toxicity. Symptoms vary, but certain common syndromes may suggest particular classes of poisons. Diagnosis is primarily clinical, but for... read more ).
Initial assessment can be done by any health care practitioner trained in the assessment and management of suicidal behavior. However, all patients should have a thorough suicide risk assessment—which is usually done by a psychiatrist, psychologist, or other trained mental health care practitioner—as soon as possible. Decisions must be made about whether patients need to be voluntarily admitted or involuntarily committed for treatment, and whether restraint is necessary (see also Behavioral Emergencies). Patients with a psychotic disorder and some with severe depression and an unresolved crisis should be admitted to a psychiatric unit. Patients with manifestations of potentially confounding medical disorders (eg, delirium, seizures, fever) may need to be admitted to a medical unit with appropriate suicide precautions.
After a suicide attempt, the patient may deny any problems because the severe depression that led to the suicidal act may be followed by a short-lived mood elevation. Nonetheless, the risk of later, completed suicide is high unless the patient receives ongoing treatment and psychosocial support.
Suicide risk assessment identifies the key drivers contributing to the individual's current suicide risk and helps the clinician plan appropriate treatment. It consists of the following:
Establishing rapport and listening to the patient's narrative
Understanding the suicide attempt, its background, the events preceding it, and the circumstances in which it occurred
Inquiring about mental health symptoms and any medications or alternative treatments the patient may be taking for treatment of their mental health condition or relief of symptoms
Fully assessing the patient’s mental state, with particular emphasis on identifying depression, anxiety, agitation, panic attacks, severe insomnia, other mental disorders, and alcohol or drug use disorders (many of these problems require specific treatment in addition to crisis intervention)
Thoroughly understanding personal and family relationships as well as social networks, which are often pertinent to the suicide attempt and follow-up treatment
Interviewing close family members and friends
Inquiring about the presence of a firearm or other lethal means in the house and providing lethal means counseling (this may involve facilitating the safe storage or disposal of lethal means away from the home)
Mental health management
Safety planning, the first step after assessment, is an essential intervention that is done to help patients identify triggers to suicidal planning and develop plans to deal with suicidal thoughts when they occur ( 3, 4 Management references Suicide is death caused by an intentional act of self-harm that is designed to be lethal. Suicidal behavior encompasses a spectrum of behavior from suicide attempt and preparatory behaviors... read more ). Other steps clinicians should take include providing the patient with crisis resources, counseling on removal or storage of lethal means ( 5, 6 Management references Suicide is death caused by an intentional act of self-harm that is designed to be lethal. Suicidal behavior encompasses a spectrum of behavior from suicide attempt and preparatory behaviors... read more ), and referrals for appropriate risk-reduction care (eg, cognitive-behavioral therapy, dialectical behavior therapy, collaborative assessment and management of suicidality [CAMS], family therapy; 4, 7–10 Management references Suicide is death caused by an intentional act of self-harm that is designed to be lethal. Suicidal behavior encompasses a spectrum of behavior from suicide attempt and preparatory behaviors... read more ). Clinicians can also provide the patient with more frequent contact through outpatient visits or various forms of communication, some of which can be provided by other members of the health care team ( 11 Management references Suicide is death caused by an intentional act of self-harm that is designed to be lethal. Suicidal behavior encompasses a spectrum of behavior from suicide attempt and preparatory behaviors... read more ).

Prevention of Suicidal Behavior
A public health model can be used to scale suicide-prevention strategies. Implementing key strategies across an entire population (universal) can drive down suicide rates. Suicide-prevention efforts are, therefore, critically important at the regional and national levels. These efforts are supplemented by effective health care in reducing suicide risk. Interventions at the community level have also shown promising results for reducing suicide risk.
There are school-based and public health interventions. One example is the Sources of Strength suicide-prevention program, which is delivered by adolescent peer leaders in high schools ( 1 Prevention references Suicide is death caused by an intentional act of self-harm that is designed to be lethal. Suicidal behavior encompasses a spectrum of behavior from suicide attempt and preparatory behaviors... read more ). Studies also show that appropriately training volunteers who staff suicide lifelines helps callers and can thus save lives ( 2 Prevention references Suicide is death caused by an intentional act of self-harm that is designed to be lethal. Suicidal behavior encompasses a spectrum of behavior from suicide attempt and preparatory behaviors... read more ).
Another powerful example of the effectiveness of universal and selective suicide-prevention programming is evidenced by the outcomes associated with Garrett Lee Smith (GLS) Memorial Act grants. These grants have funded youth suicide-prevention activities in the United States since 2004, on college campus as well as in community and tribal settings in many states. Over a 15-year period, a large proportion of counties in the United States received financial funding to engage in youth suicide-prevention initiatives, including the following ( 3 Prevention references Suicide is death caused by an intentional act of self-harm that is designed to be lethal. Suicidal behavior encompasses a spectrum of behavior from suicide attempt and preparatory behaviors... read more ):
Establishment of outreach, awareness-raising, and screening programs
Provision of “gatekeeper” training (ie, educating people in key front-line roles to recognize suicide risk and intervene accordingly)
Development of coalitions (which typically include a number of local groups, eg, local government departments of mental health or suicide prevention, nonprofit organizations focused on suicide prevention, educators, parent groups, faith-based groups, law enforcement, etc)
Implementation of policies and/or protocols
Establishment and funding of hotlines
Forty percent of GLS grants are awarded in rural areas of the United States, where suicide rates are higher and where resources for programs and clinical treatment tend to be much less available than they are in other areas. In one study, counties with GLS activities were compared with control counties that had not been exposed to GLS programs. All counties were matched for demographic characteristics (race/ethnicity makeup, median household income, unemployment rates, and suicide rates of youth and adults). Significant reductions were found both for short- and longer-term impact on suicidal behaviors and suicide deaths. The positive effect was greatest in rural areas of the United States ( 3, 4 Prevention references Suicide is death caused by an intentional act of self-harm that is designed to be lethal. Suicidal behavior encompasses a spectrum of behavior from suicide attempt and preparatory behaviors... read more ).
Another innovative nationwide initiative in the United States led by the American Foundation for Suicide Prevention (Project 2025) aims to reduce the US suicide rate by 20% by 2025.
In the clinical arena, there is consensus that patients who are admitted to the hospital after a suicide attempt are at greatest risk of death by suicide during the first few days or weeks after discharge, and the risk remains high during the first 6 to 12 months after discharge. After that, the risk waxes and wanes but is always higher than in people who have never been suicidal.
Consequently, before patients are discharged, they—along with family members and/or close friends—should be counseled about the immediate risk of dying by suicide, and an appointment for follow-up care in the first week after discharge should be made. A simple telephone call or two after discharge has been shown to significantly reduce the occurrence of repeat attempts. In addition, the patient and family members or friends should be told the names, doses, and dose frequency of the patient's drugs.
During the first weeks after discharge, family and friends should make sure that
The patient is not left alone.
The patient's adherence to the prescribed drug regimen is monitored.
The patient is asked daily about general state of mind, mood, sleep pattern, and energy (eg, for getting up, dressing, and interacting with others).
The patient's family member or friend should take the patient to follow-up appointments and should inform the health care practitioner of the patient's progress or lack of it. These interventions should be continued for several months after discharge.
Although some attempted or completed suicides are met with surprise and shock, even by close relatives and associates, clear warnings may have been given to family members, friends, or health care practitioners. Warnings are often explicit, as when patients actually discuss plans or suddenly write or change a will. However, warnings can be more subtle, as when patients make comments about having nothing to live for or being better off dead.
On average, primary care physicians encounter ≥ 6 potentially suicidal people in their practice each year. About 77% of people who die by suicide were seen by a physician within 1 year before killing themselves, and about 32% had been under the care of a mental health care practitioner during the preceding year.

Each depressed patient should be questioned about thoughts of suicide. The fear that such inquiry may implant the idea of self-destruction is baseless. Inquiry helps the physician obtain a clearer picture of the depth of the depression, encourages constructive discussion, and conveys the physician’s awareness of the patient’s deep despair and hopelessness.
Even people threatening imminent suicide (eg, those who call and declare that they are going to take a lethal dose of a drug or who threaten to jump from a high height) are thought to have some desire to live. The physician or another person to whom they appeal for help must support the desire to live.
Emergency psychiatric aid for suicidal people includes the following:
Establishing a relationship and open communication with them
Inquiring about current and past psychiatric care and drugs currently being taken
Helping sort out the problem that has caused the crisis
Offering constructive help with the problem, which includes a written safety plan developed with the patient
Beginning treatment of the underlying mental disorder
Referring them to an appropriate place for follow-up care as soon as possible
Discharging low-risk patients in the company of a loved one or a dedicated and understanding friend

Treatment of depression and risk of suicide
The combination of antidepressants and some proven short-term psychotherapy is the ideal treatment for depression Treatment Depressive disorders are characterized by sadness severe enough or persistent enough to interfere with function and often by decreased interest or pleasure in activities. Exact cause is unknown... read more .
People with depression have a significant risk of suicide and should be carefully monitored for suicidal behaviors and ideation. Risk of suicide may be increased early in the treatment of depression, when psychomotor retardation and indecisiveness have been ameliorated but the depressed mood is only partially lifted. When antidepressants are started or when doses are increased, a few patients experience agitation, anxiety, and increasing depression, which may increase the likelihood of suicidal thoughts and even behavior in rare instances.
Recent public health warnings about the possible association between use of antidepressants and suicidal thoughts and attempts in children, adolescents, and young adults have led to a significant reduction (> 30%) in antidepressant prescriptions to these populations. However, youth suicide rates increased by 14% during the same period. Thus, by discouraging pharmacologic treatment of depression, these warnings may have temporarily resulted in more, not fewer, deaths by suicide. Together, these findings suggest that the best approach is to encourage treatment, but with appropriate precautions such as
Dispensing antidepressants in sublethal amounts
Preferentially using antidepressants that are not lethal if taken in overdose
Providing more frequent monitoring and visits early in treatment
Giving a clear warning to patients and to family members and significant others to be alert for symptoms such as agitation, insomnia, or suicidal ideation

Lithium, even in low doses, is highly effective as an anti-suicidal drug for recurrent depression. In addition, clozapine reduces suicide risk in patients with schizophrenia.
There are multiple new treatments under investigation for the depressed suicidal patient, including psychologic interventions and medical interventions with intranasal esketamine and drugs used for treatment of alcohol and opioid withdrawal. Intranasal esketamine is now approved for adults with treatment-refractory depression and those with major depressive disorder and suicidal ideation.

ECT and transcranial magnetic stimulation (rTMS) have been approved for treatment-resistant depression and can be considered for patients with severe treatment-refractory depression, psychotic depression, or bipolar disorder. Both of these forms of treatment may also be helpful in reducing suicide risk ( 1, 2 Treatment references Suicide is death caused by an intentional act of self-harm that is designed to be lethal.

Effect of Suicide
Any suicidal act has a marked emotional effect on all involved. Losing someone to suicide is a particularly painful and complex type of loss. Suicide-related grief differs from other types of loss because of unanswered questions surrounding why someone died by suicide and because many people have limited knowledge about suicide. In an effort to make sense of the inexplicable and shocking event (suicide), people frequently launch an intense search for information and generate a series of hypotheses about why the suicide occurred. This can lead to guilt, blame, and anger directed at themselves and others for not having prevented the suicide, and also anger at the loved one who died. This natural part of suicide grief is generally extremely intense in the initial few months, and often lessens in intensity in the second year and beyond.
A large number of individuals are affected by each suicide death, including family members, friends, colleagues and others. An international meta-analysis of population-based suicide loss studies found 4.3% of community members had experienced another’s suicide in the past year, and 21.8% during their lifetime. In the United States, even higher rates of exposure were found. From a national sample of 1432 adults, 51% had been exposed to suicide and 35% met criteria for suicide bereavement (defined as experiencing moderate to severe emotional distress related to the suicide loss) at some point in their life ( 1–3 Effect of suicide references Suicide is death caused by an intentional act of self-harm that is designed to be lethal.

The physician can provide valuable assistance to patients who are suicide bereaved.
For clinicians who lose a patient to suicide, the experience can be far more distressing than other clinically related deaths. It is often similar to the traumatic and profoundly distressing experience of the death of a physician's family member rather than to the loss of a patient. In one study, half of psychiatrists who lost a patient to suicide had scores on the Impact of an Event Scale comparable to those of a clinical population who had experienced the death of a parent ( 4 Effect of suicide references Suicide is death caused by an intentional act of self-harm that is designed to be lethal.

The loss experience for health professionals often has both personal and professional ramifications, which can include anguish, feeling of guilt, self-doubt, complicated grief, and even thoughts of leaving the profession. There are resources available to clinicians for support through several organizations (American Foundation for Suicide Prevention, American Association of Suicidology, Jed Foundation; [ 5 Effect of suicide references Suicide is death caused by an intentional act of self-harm that is designed to be lethal.

Physician Aid in Dying
Physician aid in dying (formerly, assisted suicide) refers to the assistance given by physicians to people who wish to end their life. It is controversial but legal in 9 US states (California, Colorado, Hawaii, Maine, Montana, New Jersey, Oregon, Vermont, Washington) and the District of Columbia and is under consideration in 17 other states. All states where physician aid in dying is legal have guidelines for participating patients and physicians, such as eligibility and reporting requirements (eg, the patient must be mentally competent and have a terminal illness with a life expectancy of < 6 months). Voluntary euthanasia is legal in the Netherlands, Belgium, Colombia, and Luxembourg. Assisted suicide is legal in Switzerland, Germany, and Canada.
Physician-assisted suicide (or aid in dying) involves making lethal means available to the patient to be used at a time of the patient’s own choosing. In voluntary active euthanasia, the physician takes an active role in carrying out the patient’s request; it usually involves IV administration of a lethal substance.
Despite the limited availability of physician aid in dying, patients with painful, debilitating, and untreatable conditions may initiate a discussion about it with a physician.
Physician aid in dying may pose difficult ethical issues for physicians.
