Patient History

A host of thoughts and behaviors are associated with self-destructive acts. Although many assume that people who talk about suicide will not follow through with it, the opposite is true; a threat of suicide can lead to the completed act, and suicidal ideation is highly correlated with suicidal behaviors.[7][8][9][10]

Numerous activities are associated with committing suicide, including the following:

• Making a will
• Getting the house and affairs together
• Unexpectedly visiting friends and family members
• Purchasing a gun, hose, or rope
• Writing a suicide note
• Visiting a primary care physician

With regard to the last item, a significant number of people see their primary care physician within 3 weeks before they commit suicide. They come for a variety of medical problems, but rarely will they state they are contemplating suicide. Therefore, the practitioner must pay attention to the entire person; the physician must look for factors in the patient's life beyond the chief complaint.

Suicide-related characteristics

Individuals who are suicidal have a number of characteristics, including the following:

• A preoccupation with death
• A sense of isolation and withdrawal
• Few friends or family members
• An emotional distance from others
• Distraction and lack of humor - They often seem to be "in their own world" and lack a sense of humor (anhedonia)
• Focus on the past - They dwell in past losses and defeats and anticipate no future; they voice the notion that others and the world would be better off without them.
• Haunted and dominated by hopelessness and helplessness - They are without hope and therefore cannot foresee things ever improving; they also view themselves as helpless in 2 ways: (1) they cannot help themselves, and all their efforts to liberate themselves from the sea of depression in which they are drowning are to no avail; and (2) no one else can help them

Assessing Suicide Risk

A clear and complete evaluation and clinical interview provide the information upon which to base a suicide intervention. Although risk factors offer major indications of the suicide danger, nothing can substitute for a focused patient inquiry. However, although all the answers a patient gives may be inclusive, a therapist often develops a visceral sense that his or her patient is going to commit suicide. The clinician's reaction counts and should be considered in the intervention.[11][12][13][14]

Suicidal Ideation

Determine whether the person has any thoughts of hurting him or herself. Suicidal ideation is highly linked to completed suicide. Some inexperienced clinicians have difficulty asking this question. They fear the inquiry may be too intrusive or that they may provide the person with an idea of suicide. In reality, patients appreciate the question as evidence of the clinician's concern. A positive response requires further inquiry.

Suicide Plans

If suicidal ideation is present, the next question must be about any plans for suicidal acts. The general formula is that more specific plans indicate greater danger. Although vague threats, such as a threat to commit suicide sometime in the future, are the reason for concern, responses indicating that the person has purchased a gun, has ammunition, has made out a will, and plans to use the gun are more dangerous. The plan demands further questions. If the person envisions a gun-related death, determine whether he or she has the weapon or access to it.

The Relationship Between Suicidal Ideation, Plans, and Attempts

In 2014, 9.4 million adults aged 18 years or older who responded to the National Survey on Drug Use and Health (NSDUH) reported they had thought seriously about trying to kill themselves at any time during the past 12 months. Those who had serious thoughts of suicide were then asked whether they made a plan to kill themselves or tried to kill themselves in the past 12 months. Of the 9.4 million adults with serious thoughts of suicide, 2.7 million reported they had made suicide plans, and 1.1 million made a nonfatal suicide attempt. Among the 1.1 million adults who attempted suicide in the past year, 0.9 million reported making suicide plans, and 0.2 million did not make suicide plans. Nearly one-third of adults who had serious thoughts of suicide made suicide plans, and about 1 in 9 adults who had serious thoughts of suicide made a suicide attempt. In other words, more than two-thirds of adults in 2014 who had serious thoughts of suicide did not make suicide plans, and 8 out of 9 adults who had serious thoughts of suicide did not attempt suicide. This data show that suicidal thoughts can serve as an indicator of suicidal plans and attempts.

Purpose of Suicide

Determine what the patient believes his or her suicide would achieve. This suggests how seriously the person has been considering suicide and the reason for death. For example, some believe that their suicide would provide a way for family or friends to realize their emotional distress. Others see their death as a relief from their own psychic pain. Still others believe that their death would provide a heavenly reunion with a departed loved one. In any scenario, the clinician has another gauge of the seriousness of the planning.

Potential for Homicide

Any question of suicide also must be coupled with an inquiry into the person's potential for homicide. Suicide is often thought to represent aggression turned inward, whereas homicide represents aggression turned outward. Because suicide constitutes an aggressive act, the question regarding homicidal tendencies must be asked. 

A mixed-methods study in the UK analyzed 60 homicide-suicides and found that most victims were spouse/partners and/or children. Most perpetrators were male (88%), and most victims were female (77%). Few perpetrators had been in recent contact with mental health services before the incident (12%).

Additional Questions

Collateral questions should be asked based on the reviewed risk factors. These questions deal with any family members or friends who have killed themselves and include questions about symptoms of depression, psychosis, delirium and dementia, losses (especially recent ones), and substance abuse.

Intervention

The treatment of a suicidal patient involves a 2-phase process. First and foremost, the patient’s safety must be assured; this is the intervention. Intervention is based on the application of risk factors coupled with a clinical inquiry. The second step is treatment aimed at diagnosing and treating the underlying mental disorder.[15][16][17][18][19]

First phase of intervention

In many cases, swift, decisive intervention can prevent a person from committing suicide. Because of this preventable aspect of suicide, recognizing and taking action if the potential arises is critical. Based on the clinical assessment and all of the information available, if the person is indeed suicidal, the intervention should consist of multiple steps.

The individual must not be left alone. In the ED, such a recommendation is handled easily by hospital security personnel. In other settings, summon assistance quickly. In an isolated place, call 911. Involve family or friends; they can remain with the patient while treatment arrangements are made.

Remove anything that the patient may use to hurt or kill him or herself. Remove sharp or potentially dangerous objects. Ask the patient for any weapon, such as knives or pills, and secure them away from the patient.

The suicidal patient should be treated initially in a secure, safe, and highly supervised place. Inpatient care at a hospital offers one of the best settings. Most managed care companies recognize the medical necessity of hospitalization in situations in which the suicide danger is acute.

A study of the association between the provision of mental health services and suicide rates found that removing ligature points (places where things like ropes could be attached to) was associated with significant reductions in the overall psychiatric inpatient suicide rate and in the rate of inpatient suicide by hanging. Similarly, assessing other available sources of self-destructive implements such as pills and guns is critical.

Patients who attempt to commit suicide with prescribed medications represent one of the greatest clinical challenges. The dilemma involves balancing the fact that psychotropic drugs alleviate mental illness symptoms with the reality that some patients will use the very same medications to commit suicide. Gjelsvik et al. highlight this conundrum in their study in which patients who engage in deliberate self-poisoning had a greater prescribed medication load compared with the general population, and that this medical load is more important in determining self-poisoning episodes than the timing of collection of prescribed medication prior to an episode.This study points out the need to pay attention to the amount of stockpiled medications available to the potentially self-destructive patient.

Second phase of intervention

After the initial intervention, which usually includes hospitalization, it is critical that there be in place an ongoing management treatment plan. The heart of the second phase of the intervention is addressing the underlying cause of the self-destructive behavior. If the patient has selected suicide to escape physical pain, then a comprehensive pain management program must be initiated. If the patient is depressed, then the depression must be treated with medication and psychotherapy. If the suicide attempt has been in response to the patient with schizophrenia struggling with destructive hallucinations and delusions, then these must be aggressively treated. The key remains an accurate assessment and diagnosis followed by a comprehensive treatment plan.

One would expect that intense intervention efforts following a suicide attempt would be effective in lowering morbidity and mortality. To test this theory, Morthorst et al. assessed the efficacy of the outpatient intervention in patients older than 12 years admitted to regional hospitals in Copenhagen with a suicide attempt within the past 14 days. The intervention consisted of assertive outreach that provided crisis intervention and flexible problem-solving. This approach, assertive intervention for deliberate self-harm, incorporated motivational support and actively assisted patients to scheduled appointments. The study followed 243 patients for 12 months. Rates of subsequent suicide attempts did not differ significantly between the intervention and control groups. Although this study did not show the advantage of an intensive follow-up care, it does point out the need for a clear, definite, and defined a postsuicide attempt treatment plan.

A study of brief CBT in a cohort of active-duty military personnel in Colorado who either attempted suicide or experienced suicidal ideation found the treatment effective in preventing follow-up suicide attempts. Over the course of two years, 8 out of 76 participants (13.8%) in treatment as usual combined with brief CBT and 18 participants out of 76 (40.2%) who did not receive CBT made at least one attempt at suicide. Data show that soldiers treated with brief CBT were approximately 60% less likely to attempt suicide than soldiers who did not receive the therapy.

This section details steps a clinician should take in cases of completed suicide. Practitioners must work with the patient's family and friends, as well as with the other patients who knew the deceased.

Upon learning of the death of a patient, focus on the immediate situation. Reschedule other patients and, whenever possible, meet with the family. Family members appreciate the clinician's interest and the opportunity to voice their feelings and reactions. In some situations, the family may have expected the outcome. In others, they may be hurt and angry. The clinician's job is to be responsible and responsive to them. This intervention may require more than 1 session. Be available to family members, listen to them, and share their loss.

Often, other patients knew the deceased person. Without violating confidentiality, provide extra attention to these patients. This could include sessions to allow them to express their reactions to the death and loss. If the patient who committed suicide was an inpatient, convening a group meeting and discussing the other patients' reactions is important. The staff should also have an opportunity to discuss their feelings.

Finally, the practitioner must take the time to review and discuss the event. Often, seeking a senior clinician is effective. The therapist needs an opportunity to recover and heal. Later, a psychological autopsy can be performed, but in the acute phase, the clinician requires sympathy and support.

The only way to prevent suicides is to work in an interprofessional team that includes a mental health nurse, psychiatrist, the primary care provider, social worker, and nurse practitioner. Practitioners must work with the patient's family and friends, as well as with the other patients who knew the deceased. The first step is to prevent harm to the patient and secondly, treating the cause of the behavior that is causing suicidal ideations. All patients with suicidal ideations should be closely monitored. The family should be educated about the potential signs of danger. Unfortunately, in many cases, the healthcare system does fail as many patients do go on to end their lives.[20] (Level V)
