Abstract

Would you recognize suicidal behavior in one of your patients and know how to intervene? We'll give you practical, potentially lifesaving guidelines you can follow.

 

Article Content

JOESEPH GAINES, a single, 36-year-old teacher, came to the emergency department (ED) by ambulance after his neighbor called 911. He suffered a near-fatal overdose-a failed suicide attempt. He was transferred to your medical-surgical unit after being in the intensive care unit (ICU) for 2 days. According to the ICU nurse, when Mr. Gaines regained consciousness, he was angry about being rescued.

 

Nearly 500,000 ED admissions for suicide-related injuries are reported annually, so sooner or later you're likely to care for a patient like Mr. Gaines (see Suicide in the United States: By the numbers). After a patient attempts suicide, hospital policy defines the nursing interventions needed. More difficult, however, is identifying suicide risk in a patient who's admitted for an illness or injury unrelated to a suicide attempt.

 

In this article, I'll provide an overview of suicide and suicide prevention in a medical-surgical setting and discuss risk factors, elements of an effective suicide assessment, and nursing interventions you can apply to your everyday practice.

 

Overcoming barriers

Patients rarely attempt suicide when admitted for a specific physical problem, probably because these patients are generally treated and discharged as quickly as possible. If a hospitalized patient attempts suicide, with or without a permanent loss of function such as brain damage, or commits suicide, it's a sentinel event according to The Joint Commission.

 

Admission patient-assessment forms seldom include questions about suicide, and most nurses don't routinely screen patients for suicide risk, even though patients aren't likely to volunteer information about suicidal thoughts. One study indicated that two of every three people who commit suicide may have seen a primary care provider in the month before their death, suggesting that health care professionals are missing opportunities to intervene. In hospitals, shorter stays hinder the development of nurse/ patient relationships, so patients may not feel comfortable enough to disclose suicidal thoughts to caregivers.

 

Like many nurses, you may feel uncomfortable with the topic too. For instance, you may be afraid that asking a patient about suicidal intentions may trigger suicidal thinking or behavior. Or you may not know what to say or do if he admits to having suicidal thoughts. To save lives, we need to overcome these barriers by making suicide assessment part of routine nursing assessment.

 

Let's consider some basic information you need to know before you can assess a patient's risk and intervene effectively.

 

Along the continuum

Most suicide attempts are expressions of extreme distress, not bids for attention. Suicidal behavior develops along this continuum:

 

[black small square] ideation. This is the process of contemplating suicide or the methods used without taking action. At this point, the person might not talk about these thoughts unless he's pressed.

 

[black small square] suicidal gestures. These are actions that aren't likely to be lethal, such as taking a few pills or making superficial cuts on the wrist. They suggest that the person is ambivalent about dying or hasn't planned to die. He has the will to survive, wants to be rescued, and is experiencing a mental conflict. A suicidal gesture is often called a cry for help because the person is struggling with unmanageable stress.

 

[black small square] suicide attempts. An attempt, such as taking a potentially lethal dose of medication, indicates that the person wants to die and has no wish to be rescued.

 

[black small square] suicide. The act of intentionally killing oneself may follow previous attempts, but about 30% of those who commit suicide are believed to have done so on their first attempt. Suicide results when the person can see no other option for relief from unbearable emotional or physical pain.

 

 

Physiologically speaking

Research is beginning to unravel some of the physiologic reasons for suicidal behavior. For example, psychological autopsy studies suggest that in 90% of completed suicides, the person had one or more mental disorders, usually major depression and substance abuse, particularly alcoholism. A psychological autopsy, which is a technique used to discover a suicide victim's state of mind before his death, is often used for legal purposes.

 

Researchers are also investigating how alterations in neurotransmitters such as serotonin negatively affect mood and judgment. Diminished levels of this brain chemical have been found in people with depression, impulsive disorders, or a history of suicide attempts and also in suicide victims (see The role of neurotransmitters).

 

Understanding the motivation behind suicidal behavior is difficult not only for nurses, who are dedicated to saving lives, but also for suicidal patients themselves. Those who've attempted suicide most commonly express their need to escape from an unbearable situation, usually one involving despair and mental or physical pain. Many patients describe their emotional pain as a constant, intolerable, inescapable heaviness. Depression and despair often accompany medical conditions that are characterized by physical pain, disfigurement, limited function, and loss of independence.

 

But how do you know if your patient is at risk for suicide? Let's take a closer look.

 

Recognizing risks

To prevent suicide, the first steps are identifying and understanding risk factors. A risk factor is anything that increases the likelihood that a person will harm himself, and it should alert you to the need to assess him further for suicidal ideation.

 

Consider why your patient is currently in the hospital; this may be the first indication of increased risk. For many patients, hospitalization is likely to mean bad news: a confirmed diagnosis, troubling test results, a decline in health, or difficult medical decisions. You'll need to evaluate your patient's emotional response to his medical condition, not just his physical status.

 

Don't be afraid to ask about suicidal thoughts (see Interview do's and don'ts). Most patients who are suicidal are relieved to talk about their feelings and to be assured that they aren't crazy for thinking this way. First, assess your patient for depression by asking a question like this: Are you feeling depressed (or sad or discouraged)? If the answer is yes, then ask these standard suicide assessment questions:

 

[black small square] How long have you felt like this?

 

[black small square] Do you feel that your life is no longer worth living?

 

[black small square] Are you thinking of acting on that feeling by hurting yourself or taking your own life?

 

[black small square] Do you have a suicide plan?

 

[black small square] Can you tell me about your plan?

 

 

You should ask for detailed information if your patient has a suicide plan. A plan is more likely to be lethal if he can articulate specifics, such as method and place; believes the plan can succeed; and has devised precautions to avoid interruption or discovery. Ask whether he has made final arrangements, such as a will or other instructions, or has given away treasured items. His responses will provide you with a sense of the seriousness of his suicidal intentions. If you determine that he's at risk for suicide, never leave him alone even if he can't carry out his plan in the hospital. You'll also need to implement suicide precautions.

 

Now let's take a look at what you need to do if your patient is suicidal.

 

One on one

Because a nonpsychiatric hospital environment is loaded with potentially dangerous items, you can't make it completely safe for a patient at risk for suicide. Initiate one-to-one observation status according to your facility's policy, notify his primary care provider, and explain to him why you're taking precautions. Assure him that you want to keep him safe until he's feeling less despondent and more in control. Most hospitals have a written policy on caring for a suicidal patient who has already attempted suicide like Mr. Gaines. Follow your facility's policy; obtain a copy and use it as a guide.

 

If you initiate one-to-one observation, instruct the observer to stay at least an arm's length away from the patient at all times. An appropriate observer is a staff nurse who's been trained on how to observe and how to respond. Although family members may ask to fill this role, it isn't appropriate for them to do so because they may not know how to respond. Using them could also present liability issues.

The role of neurotransmittersAffecting behavior, mood, and thought, neurotransmitters are chemical messengers released into the synapses (gaps) between neurons (nerve cells) that carry messages from one neuron to another. If a person has low levels of the neurotransmitters norepinephrine and serotonin in areas of the brain that control mood and emotion, depression may result.

Other common safety measures include:

 

[black small square] removing all sharp or hazardous objects (including plastic bags and metal coat hangers) from the patient's room

 

[black small square] requesting that food be served with paper plates and cups and plastic eating utensils

 

[black small square] taking away potentially hazardous personal items, such as shoelaces, belts, glass objects, and lighters

 

[black small square] performing a contraband check of all personal belongings

 

[black small square] telling visitors not to leave anything with the patient unless the nurse approves

 

[black small square] observing the patient to make sure he swallows medications

 

[black small square] restricting him to the unit

 

[black small square] locating him near the nurses' station

 

[black small square] placing him in a room with another patient.

 

 

I find that having the patient write and sign a no-harm contract is a good way to encourage him to start taking charge of his own behavior and become an active partner in his treatment. It might include statements such as "I won't harm myself while I'm in the hospital. I'll tell the nurse if I have thoughts of harming myself." Another early intervention is to involve the family, if your patient consents. Ask him if he has a family member or friend whom he wants to involve in his care.

 

Comprehensive documentation for your patient should include risk factor data, direct quotes that capture his suicidal thoughts or plans, actions you took to keep him safe, who you notified about his suicidal behavior, and precautions taken.

 

Working through it

Reassess your patient at least once per shift to determine his current level of suicidal intent and whether one-to-one observation should continue. Ask him to rate his level of suicidal intent on a 0-to-10 scale, with 0 meaning no thoughts of suicide and 10 meaning constant thoughts of suicide. Document the score during each shift so staff members can track trends.

 

You can also use the comparisons to help your patient understand what factors may or may not be decreasing his suicidal thoughts or underlying depression. For instance, did he have visitors, receive cards or flowers, sleep well, or participate in self-care? This will give him some insight into factors contributing to his improved mood or sense of hope.

 

You can help your patient by talking about his experience in a sincere and supportive way. You'll want to spend uninterrupted, but not necessarily long, periods with him. One approach is to relieve the observer for breaks and meals. Focus your interactions on your patient's present crisis. For example, you might say, "Help me understand. Can you tell me what's going on in your life that's unbearable?" This approach encourages him to talk about his circumstances and perceptions. To assess his emotional status, focus on how he feels. After a suicide attempt, some patients are embarrassed and some are relieved that they were rescued. Others, like Mr. Gaines, are disappointed and angry.

 

As his nurse, show empathy by listening as your patient expresses his frustration. If he says he's feeling discouraged or depressed, explain that, until it lifts, depression limits a person's ability to see other options. Suicidal behaviors are often transient and time limited and can be precipitated by a personal crisis. Focus on the precipitating factors and events leading up to the attempt and look for an opportunity to talk about alternative problem-solving approaches he could have used. For example, you might ask, "Have you ever been in a similar situation? How did you handle that?" Ask open-ended questions, listen, and reinforce his efforts to work through his feelings and concerns. Don't try to resolve his problems, give advice, or point out how much better off he is than someone who's less fortunate.

 

Ultimately, you want your patient to regain a sense of hope. This process begins with helping him identify personal strengths and setting small achievable goals. Listen for and pick up on any reference to the future, which is a positive sign suggesting improvement.

 

What are the treatments available for a patient who's suicidal as a result of depression? That's up next.

 

Looking to the future

Standard treatment for a patient with major depression is antidepressant medication combined with counseling or other talk therapy. Teach your patient about his medications and explain that these drugs may not be fully effective for weeks. In addition, prepare him for follow-up psychiatric care. He may have a psychiatric consult while he's in your unit or he may be transferred to a psychiatric facility or the psychiatric unit within your facility. Informing him of this in advance will help him accept and cooperate with this routine practice.

 

If your patient is discharged home, ask his permission to have a family member ensure that the home environment is safe and free from weapons, potentially dangerous medications, and other hazards.

 

Assess and act

By knowing how to assess a patient's risk of suicide and taking appropriate nursing actions, you may prevent a suicide attempt. You don't need to be a psychiatric nurse to recognize a vulnerable patient and initiate interventions that may save his life.

Interview do's and don'ts

When interviewing a patient at risk for suicide, follow these guidelines.

 

Do set clear goals

The assessment interview isn't meant to be a random discussion. Make sure you have clearly set goals, such as investigating for depression or suicidal thoughts.

 

Do heed unspoken signals

Listen carefully for indications of anxiety or distress. What topics does the patient ignore or pass over vaguely? You may find important clues in his method of self-expression and in the subjects he avoids.

 

Do check yourself

Monitor your own reactions. The patient may provoke an emotional response strong enough to interfere with your professional judgment.

 

Don't rush

Don't rush through the interview. Remember, building a trusting therapeutic relationship takes time.

 

Don't make assumptions

Don't make assumptions about how past events affected the patient emotionally. Try to discover what each event meant to him. For example, if he says one of his parents died, don't assume that the death provoked sadness. A death by itself doesn't cause sadness, guilt, or anger. What matters is how the patient perceives the loss.

 

Don't judge

Don't let personal values cloud your professional judgment.
