Clinicians most commonly encounter the suicidal adolescent in the emergency department or at an emergency consultation shortly after the youth has made a suicide attempt or made a threat of suicide to a parent, sibling, teacher, or friend. The clinician’s task is to evaluate the risk of death, determine the nature of the underlying mental condition, and put in place a safe and effective treatment plan. Less often, a clinician will be asked to provide advice to a parent or to a school whose child or student has recently committed suicide.
The clinician and the teenager who has recently attempted suicide
Although completed suicide is relatively rare in adolescence (among teens aged 15–19, the rate is 8 per 100,000 teens per year), suicidal ideation and suicide attempts are more common during these years than at any other time in life. In a 12-month period, approximately 5% of male and 12% of female high school students will make a suicide attempt, and upwards of 20% of high school students will think about suicide (
1). Suicide attempts are often repeated, and about half of all teen attempters will attempt to commit suicide more than once (
2).
All forms of suicidality—completed suicides, suicide attempts, and suicidal ideation—are less common before puberty, perhaps reflecting a similar infrequency of depression and substance abuse. The incidence of completed suicide increases steadily through the adolescent years, peaking in the early to mid-20s. Suicide attempts, by contrast, reach a peak incidence at age 16 and then decline. Thus, while suicide is a characteristically adult behavior with beginnings that are apparent in adolescence, there is something truly “adolescent” about many suicide attempts, and this fact has considerable clinical relevance.
The adolescent nature of many suicide attempts can be discerned in the most common precipitants at this age. Stressful interpersonal interactions trigger the majority of youth suicides and attempts, often within minutes or hours of some form of dispute or disciplinary crisis (
3,
4), typically a dispute with parents over limit setting, such as the timing of a curfew, or a disciplinary problem at school or with the law. As adolescence proceeds, and as parents adapt to the increasing competence of their children, these limits change, and this very flexibility could invite misunderstandings and friction. In addition, the suicide-prone teen—who is, like his or her adult counterpart, often irritable, prone to aggressive outbursts, and unduly sensitive to slights and losses (
5)—lacks experience in dealing with and managing interpersonal problems with parents and friends. A disagreement that an older person might navigate with a minimum of fuss can seem unmanageable to the younger teen.
These factors lead to the striking differences in incidence between attempts and completions in the adolescent age group. Attempts are about 4,000 times more common than suicides in teen girls and about 400 times more common in teenage boys. These discrepancies, coupled with the familiar nature of many of the precipitants, present a challenge for the clinician. A tradition has developed in Europe to distance suicide attempts in the young, especially those made by females with an ineffective ingestion, from suicide, using terms such as “parasuicide” and “deliberate self-harm” in its place. The differentiation assumes that there are differences in psychopathology and natural history between young suicide completers or attempters and their older counterparts. Until these euphemisms are better defined, they may only hinder the clinician. Almost all suicide attempters, of both genders and of all ages, will say that at the time of their attempt they intended to die. Methods seem to be determined more by culture and gender than by intent. One-fifth of girls who commit suicide do so by ingestion, and in some countries, where the fatal effects of the habitual ingestants are not easily reversed by treatment, the suicide rate among females is higher than among males and is predominantly from ingestions. The clinician, aware that most attempts will not lead to death but that a small number will, walks a tightrope.
In practice, the encounter with the suicidal teen is resolved by choosing between admitting the patient to an inpatient unit, retaining the patient under observation in a day unit or emergency ward, or making arrangements for further evaluation and the initiation or continuation of regular outpatient treatment. Choosing from among these options can be made easier by a systematic appraisal of the youth’s recent suicidal and other behavior and current mental state.
Deciding to hospitalize
The most common reason for admitting a suicidal teenager to the hospital is to ensure safe care while obtaining a more thorough evaluation or while waiting for the effects of treatment to take hold. However, hospitalization is not without costs. The teen’s friends, parents, and teachers are likely to hear of it, and negative labeling can follow. An admission can lead to a significant financial burden for the family or cause them to lose an important fraction of lifetime medical benefits. Furthermore, a hospital environment can promote contagious behaviors, such as “cutting,” and hospitalization is often recalled by young people as a traumatic experience. The task of choosing between admitting, holding, or discharging the patient is therefore one that cannot be taken lightly.
The clinician can reasonably consider the following to help in making this difficult decision:
1.
Do any features of the suicide attempt itself indicate serious intent? The medical seriousness of an ingestion is not easy to judge. Adolescents tend to overestimate the potential lethality of medications. Swallowing eight over-the-counter analgesic tablets might be regarded as trivial by the clinician, but the youth might have expected it to be fatal. Self-cutting is not normally regarded as a suicidal behavior, although relatively rare attempts to stab oneself might be. This uncertainty can sometimes be resolved by asking these teen patients whether, when they cut themselves, they wanted to die. Attempts at hanging are usually considered serious, but it is not uncommon for a teenager to place a necktie or a belt around his or her neck, pull on it for a short time, and then abandon thoughts of suicide when this approach doesn’t work; sometimes telltale marks around the neck can be seen in such patients. Other features of the suicide attempt that can indicate serious intent are the degree of effort made to obtain the means used; whether there were any preparatory activities, such as writing and leaving a suicide note, preparing a will, or giving away possessions; and whether any active steps were taken to avoid discovery, as indicated by where and when the attempt was made.
2.
Intent can also be inferred from
the patient’s mental state. Some patients make no secret of the fact that they still wish to die, and in these cases admission is always needed. Admission is also needed for patients who are psychotic, who have bipolar disorder, or who are clinically depressed. Establishing the diagnosis will nearly always require that the clinician obtain a history from a third party, usually a family member; this should always be done before the patient is discharged from the emergency department. In prospective studies of patients who went on to commit suicide shortly after a mental health evaluation, the features most likely to be present at the time of the evaluation were restlessness, agitation, and activation (
6).
Deciding to discharge to outpatient care
A majority of adolescent suicide attempters lose contact with the clinic where they were first seen after one to three outpatient visits (
8,
9). This attrition rate is somewhat higher than is usually seen with teen patients, and it might reflect the self-regulating effect of many suicide attempts, whereby the patient feels better after the attempt. It might also reflect the perceived relevance and helpfulness of the treatment offered or poor administrative procedures that allow referrals to fall through the cracks. Given that many of the attempters will go on to attempt suicide again, there is no room for complacency in this aspect of management.
Antidepressants should not be prescribed until the clinician has had an opportunity to reevaluate the patient’s mood state after the current crisis is over. If the patient is clearly depressed at the time of the attempt, hospital admission would be preferable to arranging outpatient treatment.
Clinicians often propose to “contract for safety” with a suicidal teen before discharging the youth. While this approach might convey to the patient that he or she is being taken seriously, the clinician should not be overconfident about its value. Follow-up studies of repeat attempters indicate that as many as a third had previously signed such a contract (
10). That said, preparing a contract can provide an opportunity for the clinician to assess and rehearse how the patient would respond if he or she again encountered the stressor that led to the recent behavior.
Other forms of intervention in the emergency department have been tried, notably convening a family meeting to examine the recent crisis and aspects of family dysfunction (
11), but this approach has a limited effect in securing attendance at later appointments.
The patient should ideally be discharged from the emergency department only after an appointment has been scheduled. If this is not possible, the clinician should assume responsibility for asking an assistant or a colleague to contact the patient’s home with an appointment as soon as possible after discharge or else retain the patient in the emergency department until a precise disposition plan can be arranged. A failure to do this and a failure to note it in the chart could render the clinician liable in the event of a later attempt or death.
