SCREENING AND ASSESSING THOSE AT RISK

Because a significant proportion of individuals who die by suicide have seen a health professional within a few days prior to their suicide attempt, suicide screening and assessment of risk for suicide are important steps to be taken in all healthcare settings.

Suicide Screening

Suicide prevention screening refers to a quick procedure in which a standardized instrument or tool is used to identify individuals who may be at risk for suicide and in need of assessment. It can be done independently or as part of a more comprehensive health or behavioral health screening.

The following are validated, evidence-based suicide risk screening tools:

  • Beck Fast Scan: Seven questions that can help determine the intensity and severity of depression
  • Suicide Risk Screen: 10-item questionnaire often used to screen for suicide in young people
  • Patient Health Questionnaire (PHQ): Nine questions about self-harm, also used to identify patients at high risk of suicide
  • SAFE-T: Can be used in an outpatient setting; offers insight into the extent and nature of suicidal thoughts and harmful behavior
  • Columbia-Suicide Severity Rating Scale (C-SSRS): Available in multiple languages for prehospital use to assess for the presence of harmful behavior; also assesses for any known suicide attempts and suicide ideations and behaviors
  • Ask (ASQ) Suicide Screening: Four brief questions to screen medical patients ages 8 years and above
  • SBQ-R: A psychological, four-item questionnaire to identify risk factors for suicide in adolescents and adults
    (NIMH, 2022; Columbia University, 2021; CEBC, 2020)

Recognizing Suicide Warning Signs

Besides screening for risk factors for suicide, it is important to be able to recognize statements, behaviors, and moods that indicate an individual may be at immediate risk for suicide.

Statements by a coworker or patient that constitute a suicide warning sign include language about:

  • Killing oneself
  • Feeling hopeless
  • Having no reason to live
  • Being a burden to others
  • Feeling trapped
  • Having unbearable pain

Behaviors that may signal risk—especially when related to a painful event, loss, or change—include:

  • Increased use of alcohol or drugs
  • Searching for a method to end their life, e.g., online search
  • Withdrawing from activities
  • Risky behaviors
  • Isolating from family and friends
  • Sleeping too much or too little
  • Visiting or calling people to say goodbye
  • Giving away prized possessions
  • Aggression
  • Fatigue
  • Writing a will and making final arrangements

People considering suicide often display one or more of the following moods:

  • Depression
  • Anxiety
  • Loss of interest
  • Irritability
  • Humiliation/shame
  • Agitation/anger
  • Relief/sudden improvement
    (AFSP, 2023)

Suicide Assessment for Those at Risk for Suicide

The most effective assessment of the individual who has screened positive for suicidal ideation begins with the establishment of a therapeutic relationship. In order to effectively intervene with someone who may be at risk for suicide, it is essential that healthcare professionals are skilled at establishing rapport quickly. It is imperative that the person be given privacy, be shown courtesy and respect, and be made aware that the concerned individual wants to understand what has happened or is happening to them.

When attempting to elicit information from suicidal persons, it should be remembered that challenging or direct questions, which could be interpreted as critical, will rarely be of benefit. The individual with suicidal thoughts should be encouraged and given the opportunity to express thoughts and feelings and be allowed to discharge pent-up and repressed emotions. Asking open-ended questions encourages the person to elaborate on their answers, which can provide important context on their level of risk, access to means, and presence of intent (Aamar, 2021).

OPEN-ENDED QUESTIONING IN RESPONSE TO PERSONS WITH SUICIDAL IDEATION
Person’s Statement Appropriate Responses
Everyone will be better off without me.
  • Who would be better off?
  • What would be better for those people?
  • Where are you planning to go?
I just can’t bear it anymore.
  • What is so hard to bear?
  • What would make your life better?
  • When did you begin to feel this way?
I just want to go to sleep and not deal with it again.
  • What do you mean by “sleep”?
  • What is it you don’t want to deal with anymore?
I want it to be over.
  • What is it you want to be over?
  • How can you make it be over?
I won’t be a problem much longer.
  • How are you a problem?
  • What is going to change in your life so you won’t be a problem any longer?
  • When will you no longer be a problem?
Things will never work out.
  • What can you do to change that?
  • What, then, do you propose to do?
It is all so meaningless.
  • What would make life more meaningful?
  • What are some aspects of your life that make it worth living?
  • What is happening in your life that makes it so meaningless?

ASSESSING SUICIDAL INTENT

Once it is determined that suicidal ideations are present, the next step is to determine whether the patient has active (thoughts of taking action) or passive (wish or hope to die) intent. The patient should be asked if the thoughts are new and if there are changes in the frequency or intensity of chronic thoughts. It is also important to inquire about the patient’s ability to control these thoughts.

The next step is to determine if the patient has developed a suicide plan and their degree of intent. This includes asking whether or not they have made any preparations and what they are. It is also important to determine whether the patient has a history of impulsive behaviors or substance use that may increase impulsivity, and whether they have a past history of suicidal ideation and behavior.

In addition, the clinical interview includes observing whether the patient is disconnected, disengaged, or shows a lack of rapport, as these signs are associated with an increased risk of suicide (Schreiber & Culpepper, 2022).

Suicide Risk Assessment Tools

There are many tools available to assist healthcare professionals in determining suicidal intent. These assessment tools are used to assess a person’s intent to carry through. They are often used when positive results have been obtained with one of the screening tools mentioned above. The following are validated/evidence-based suicide risk assessment tools:

  • Columbia-Suicide Severity Rating Scale (C-SSRS), Risk Assessment version. The risk assessment version of this tool provides a checklist of protective and risk factors for suicide and is used along with the C-SSRS screening tool. It is appropriate in all settings for all ages and for special populations in different settings. The tool features a clinician-administered initial evaluation form, a “since last visit” version, and a self-report form. The Columbia protocol questions have also been incorporated into the SAMHSA SAFE-T model with recommended triage categories.
  • Beck Scale for Suicide Ideation (BSI). This 21-item self-report instrument can be used in inpatient and outpatient settings for detecting and measuring the current intensity of the patient’s specific attitude, behaviors, and plans to die by suicide during the preceding week. It assesses the wish to die, desire to make an active or passive suicide attempt, duration and frequency of ideation, sense of control over making an attempt, number of deterrents, and the amount of actual preparation for the contemplated attempt.
    (TJC, 2023)
Clinical Interview

The clinical interview is the “gold standard” for suicide assessment and intervention. Topics covered during this interview include suicidal ideation, plans, self-control, intent, and safety planning.

There are three effective approaches to asking about suicide:

  • Use a normalizing tone. About 60% of people who died by suicide denied suicidal ideation when asked by a healthcare provider, indicating the presence of psychological and interpersonal barriers to disclosure. It is helpful to use a statement that normalizes suicide ideation, such as: “I asked you this question because almost all people at one time or another have thoughts about suicide.”
  • Use gentle assumption. To make it easier for patients to disclose suicidal ideation, the interviewer assumes that certain thoughts and behaviors are already occurring in the person and gently structures questions accordingly. So, instead of asking if the person has been thinking about suicide, ask “When was the last time you had thoughts about suicide?”
  • Assess the person’s mood. An exploration of mood states might include asking permission to discuss mood, and then asking patients to rate their mood using a zero–10 scale. This is followed by questions that refer to the worst or lowest mood rating the person has ever had as well as what was happening at those times that made them feel so down. In order to end with a positive note, the patient is asked about the best mood rating they’ve ever had.

Explore suicidal ideation. When the patient discloses the presence of suicidal ideation, collaboratively explore the frequency, triggers, duration, and intensity of the suicidal thoughts. During this process, it is important to show curiosity, empathy, and interest instead of judgment. If the patient denies suicidal thoughts and the denial appears to be genuine, acknowledge and accept the denial, but if the denial seems forced or is combined with symptoms of depression or other risk factors, acknowledge and accept the denial but return to the topic later.

Explore suicide plans. Once rapport is established and the patient has talked about suicidal ideation, it is important to explore suicide plans. If patients admit to a plan, further exploration is crucial. Evaluation includes assessing the specificity of the plan, its lethality, availability of the means, and proximity of social support (i.e., availability of individuals who might intervene and rescue the patient) (see “Assessing the Plan, Lethality, and Risk” below).

Assess self-control. This requires asking directly about self-control and observing for agitation, arousal, or impulsivity. Arousal and agitation adversely affect self-control and are the inner push that drives persons toward suicidal acts (Sommers-Flanagan, 2022).

STEPS TO TAKE WHEN A PATIENT REFUSES ASSESSMENT
  • Obtain information from other sources, such as:
    • Collateral reports from staff
    • Patient’s past medical records
      • Past suicide attempts
      • Past nonsuicidal self-injury
      • Past episodes of suicidal thinking
    • Mental status assessment
  • For patients who are competent and refuse services, document efforts made to gain cooperation.
  • Document an explanation of the limitations of assessment and how level of risk was determined.
(Obegi, 2021)

ASSESSING THE PLAN, LETHALITY, AND RISK

The evaluation of a suicide plan is extremely important in order to determine the degree of suicidal risk. When assessing lethality of a plan, it is important to learn all the details about the plan, the method chosen, and the availability of means. People with definite plans for a time, place, and means are at high risk for suicide. Someone who is considering suicide without making a plan is at lower risk.

Suicidal deaths are more likely to occur when persons use highly damaging, fast-acting, and irreversible methods—such as jumping from heights or shooting—and do so when rescue is fruitless.

IMPULSIVITY AND SUICIDE

Some suicides are carefully planned and deliberate, while others appear to have been impulsively decided upon, involving little or no planning. Impulsiveness is thought to play an instrumental role in suicide because of the presumption that suicidal behaviors are carried out via rash decisions with little consideration for the consequences. A study of survivors of nearly lethal suicide attempts found that 1 in 4 individuals deliberated for less than 5 minutes. Another study found that 48% reported deliberating less than 10 minutes (HSPH, 2023a).

Methods of Suicide and Lethality

The desire for a painless method of suicide often leads individuals to choose a method that tends to be less lethal. This results in attempted suicides that do not end in death. For every 25 attempts, there is one death. For drug overdoses, the ratio is around 40 to 1.

The following are methods of suicide and the likelihood that they will result in death:

  • Firearms: 82.5%
  • Drowning/submersion: 65.9%
  • Suffocation/hanging: 61.4%
  • Gas poisoning: 41.5%
  • Jumping: 34.5%
  • Drug/poisoning: 1.5%
  • Cutting/piercing: 1.2%
  • Other: 8.0%
    (HSPH, 2023b)

It is of utmost importance for clinicians to recognize that these methods, as well as other highly lethal suicide methods, are widely accessible and must be considered when determining the disposition of someone who has suicidal ideations.

Factors that influence the lethality of a chosen method include:

  • Intrinsic deadliness. A gun is intrinsically more lethal than a bottle of pills.
  • Ease of use. If a method requires technical knowledge, for example, it is less accessible than one that does not.
  • Accessibility. Given the brief duration of some suicidal crises, a gun in the cabinet in the hall is a greater risk than a very high building 10 miles away.
  • Ability to abort mid-attempt. More people start and stop mid-attempt than carry through. It is easier to interrupt a hanging or to call 911 after overdosing than to stop a method such as jumping off a bridge or using a gun.
  • Acceptability to the individual. The method must be one that does not cause too much pain or suffering. For example, fire is readily accessible, but it is a method seldom used in the United States.
    (HSPH, 2023b)
MOST COMMON SUICIDE METHODS USED BY NURSES

The use of firearms in death by suicide has been more common among male nurses, whereas opioids or other medications have been more commonly used as a suicidal method in female nurses. A recent study, however, has reported a distinct shift from using pharmacological agents to firearms among female nurses (UC San Diego Health, 2023).

Level of Risk

A clinical judgment that is based on all the information obtained during assessment should help to assign a level of risk for suicide and determine the setting of care.

People who are low risk of suicide:

  • Are experiencing recent suicidal ideation or thoughts
  • Have no specific current suicide plan
  • Have no clear intent to act
  • Have not planned or rehearsed a suicide act
  • Have identifiable and multiple protective factors
  • Have limited risk factors
  • Have no history of suicidal behaviors
  • Have evidence of self-control
  • Have supportive family members or significant others
  • Have a high degree of ambivalence

Most people with suicidal ideation do not necessarily want to die; they just do not want to continue living in an intolerable situation or state of mind. This ambivalence is one of the most important tools for working with such persons. Almost everyone with suicidal thoughts is ambivalent about dying, leaning toward suicide at one moment in time, and then leaning toward living the next. The healthcare professional can use this ambivalence to help focus the person on the reasons why they should live.

People who are at moderate risk:

  • Have current suicide ideation
  • Have no clear plan for suicide
  • Have had no preparatory behavioral or rehearsal of act
  • Have limited or no intention to act
  • Have limited identifiable protective factors
  • Are able to control the impulse
  • Have the ability to maintain safety, independent of external support
  • Have no recent suicidal behavior
  • Have supportive family or significant others
  • Have a high degree of ambivalence

People who are at high/severe/imminent risk:

  • Have strong, persistent suicidal ideation
  • Have strong intention to plan or act
  • Have a specific suicide plan
  • Have access to lethal means
  • Have minimal protective factors
  • Have impaired judgment
  • Have poor self-control either at baseline or due to substance use
  • Have inability to maintain safety, independent of external support
  • Have a poor social support network
  • Have severe psychiatric symptoms and/or an acute precipitating event
  • Have a history of prior suicide attempt
    (VA, 2022b)
PREDICTING SUICIDE BY RISK LEVEL

There has been no improvement in the accuracy of predicting suicides in the past 40 years.

  • 95% of “high-risk” patients will not die by suicide.
  • 50% of suicides are from “low-risk” patients.
  • 50% of individuals who complete suicide have no prior history of suicide attempts.
(PsychDB, 2021)

DOCUMENTATION OF SUICIDE RISK ASSESSMENT

Good documentation is basic to clinical practice. Accurate, sufficiently detailed, and concise records of a patient’s treatment allow for quality care and communication among providers. The best records reflect awareness of risk and the process of professional judgement that recognized it, took steps to reduce it, and balanced it with patient needs. The following documentation should be present in the record:

  • Reason for suicide assessment
  • Review of past available records
  • Evaluation of warning signs and risk and protective factors
  • Initial and ongoing suicide risk assessment
  • Access to lethal means and mitigation
  • Consultations with colleagues
  • Referrals to behavioral health
  • Rationale and follow-up for treatment options
  • Safety planning and discharge coordination
  • Plans for follow-up
