    IN THE FIELD

    Sara and Sean are dispatched to the home of a 45-year-old woman. Her neighbors have requested that

    EMS and the police check on the woman because they haven't seen her in 3 days. She was recently

    widowed, and her neighbors report that she has been very depressed.

    Sara and Sean recognize that a depressed patient may become a behavioral emergency. They wait for law

    enforcement officers to arrive before they approach the scene. After Sara and Sean ring the doorbell

    several times, the woman answers the door. She clearly has not been taking care of herself; her clothes are

    dirty, and her hair and face are unwashed. Sara begins to ask the woman questions about how she has been

    feeling lately. The woman admits to feeling depressed since her husband's death and to feeling that she

    can't take care of herself. Although the woman is calm and quiet, Sara and Sean recognize the potential for

    violence in this situation; as with all patients, they treat the woman carefully and with respect, and they

    also make sure to speak to her very gently and calmly. She agrees to be transported to a hospital where she

    can be evaluated and can receive help in dealing with her feelings.

    EMTs respond to many situations involving behavioral emergencies, from stress reactions to severe altered

    mental status resulting from illness or injury. Some behavioral emergencies result from mental illness or the

    use of mind-altering substances, such as alcohol, illegal drugs, or prescription medications. Being aware of

    behavioral emergencies and their causes will help you handle these situations and understand the options

    available to you as a caregiver. Sometimes EMTs approach an apparently safe scene, such as a medical call,

    but then discover a danger present. For this reason, it is acceptable for EMS providers to contact law

    enforcement officers prior to entering any situation.

    BEHAVIOR

    Behavior is the manner in which a person acts or performs. All physical and mental activities are part of a

    person's behavior. A great many factors can influence behavior, including cultural norms, stress levels, and

    psychological makeup.

    A behavioral emergency results when a person exhibits abnormal behavior in a situation that results in

    potential harm to himself or herself or to others ( Fig . 24 - 1). An abnormal behavior is one that is

    unacceptable or intolerable to the person, family members, or the community. It might be the result of

    extreme emotion and could lead to violence. It can also be caused by traumatic injuries or acute illness, such

    as lack of oxygen or low blood sugar.

    BEHAVIORAL CHANGES

    Many situational stresses, medical illnesses, and legal or illegal drugs, including alcohol, can alter a

    person's behavior. For example, diabetic individuals may show a change in behavior, such as

    aggressiveness, restlessness, or anxiety, if the level of sugar in their blood drops. In such cases not enough

    energy is reaching the cells, and the brain suffers from the lack of nutrients, resulting in an altered mental

    status. Lack of oxygen and inadequate blood flow to the brain are other causes of an altered mental status,

    resulting in similar behavior. These conditions may result from head injuries or other trauma with loss of

    blood.

    Other possible causes of behavioral changes are the use of mind-altering substances and extremes of body

    temperature. Many medications can affect a person's mood and behavior. When considering the potential

    that medications are affecting a patient's behavior, assess for prescription, over the counter, and illicit drug

    use. Extreme changes in body temperature can also affect a person's behavior. Excessive cold as well as

    excessive heat can cause a person to act irrationally.

    Be aware of the environment in which you find the patient, and document any findings such as

    temperature, lack of food, lack of proper ventilation, cleanliness, and so on. These findings may be

    important for you and the receiving facility to treat the patient properly.

    PSYCHOLOGICAL CRISES

    Other changes in behavior may result from mental illness and may produce psychotic thinking or

    depression. A person experiencing a psychological crisis may panic easily as a result of very little stress or

    may become agitated with no apparent or obvious provocation. These patients may be a danger to

    themselves or to others. They can be provoked to violent behavior, and their behavior can change quickly

    and unpredictably. Patients experiencing certain psychoses think and behave differently. A patient with

    paranoia may be convinced that people are plotting against him or her. A manic patient may be very

    agitated, moving and speaking rapidly without producing clear or complete sentences. A depressed patient

    may not want to move or answer any questions. Treat these patients gently, and avoid making sudden

    movements or actions so as not to scare or agitate them.

    SUICIDAL GESTURES

    When you examine a patient who may be experiencing an abnormal behavior, determine whether the

    patient may be at risk of harming himself or herself or others. A person who is notably depressed may be

    expressing thoughts of death or suicide and may seem very sad in expression and behavior. It is important

    to recognize signs of depression and suicidal gestures before the patient behaves self-destructively. Box

    24 - 1 lists some risk factors that may help you determine whether a person is at risk for suicidal behavior.

    BOX 24-1 Risk Factors for Suicide

    Patients over 40 years of age, widowed or divorced, alcoholic, or depressed

    Patients who have spoken of taking their own lives

    Patients with a previous history of self-destructive behavior

    Patients with recently diagnosed serious illness

    Patients in an environment in which there is an unusual gathering of destructive items (e.g.,

    guns or large amounts of pills)

    Patients who have recently lost a loved one

    Patients who recently were arrested or imprisoned

    Patients who have lost their job

    The fact that patients do not have any risk factors for suicide, however, does not mean that they are not at

    risk, and patients who have some risk factors may not be considering suicide. Find out from family

    members and friends if the patient has been depressed recently. Patients may seem cheerful when you are

    present, but previous indications of risk factors are extremely important. Depressed patients may be too

    exhausted to commit suicide but may be at risk thereafter.

    3. A behavioral emergency exists when the person acts in a(n)_____________ manner that may

    be a threat to himself or herself or others.

    ASSESSMENT AND EMERGENCY CARE

    SCENE SIZE-UP

    The first action EMTs should take in the emergency medical care of a patient with a suspected behavioral

    emergency is the scene size-up. Be careful when examining the patient's environment. The environment

    may be unsafe, or the patient may have an unsafe object that presents a risk. The patient may be seated in a

    defensive position or may have the fists clenched. Note whether the patient is calm or standing and

    yelling, and observe how the patient is moving. Try to determine whether the patient is under the influence

    of alcohol or other drugs. If you believe the scene is unsafe, do not enter. Contact law enforcement

    personnel as needed.

    Gather information from family members or bystanders about the patient's behavior prior to your arrival.

    Do not let the patient get between you and the nearest exit route ( Fig . 24 - 2). Stay near doors or exits if

    possible. If the scene becomes unsafe and cannot be secured after you have entered and begun care, exit as

    quickly as possible. See Chapter 9 for more detailed information regarding safety.

    Fig. 24-2 Do not allow any participant in a dispute to position himself or

    herself between you and the door or exit route.

    351

    CHAPTER 24 Behavioral Emergencies Page 7 of 16

  • Mosby's EMT-Basic Textbook - Revised Reprint, 2nd Edition

    ALERT!

    Stay near doors and exits. Never let the patient position himself or herself between you and the door,

    blocking your route of escape.

    You may need to remove the patient from the surroundings and bystanders in order to perform the

    assessment. For example, an adolescent with peers present may not answer questions correctly for fear of

    embarrassment or may not want to admit a problem in front of friends.

    BOX 24-2 Signs of Potential Patient Violence

    Sitting on the edge of the seat as if ready to move

    Clenched fists

    Yelling and using profanity

    Standing or moving toward the EMT

    Throwing things

    Holding onto a potentially dangerous object

    Any behavior that makes the EMT uneasy

    If the patient was or is displaying destructive behavior toward himself or herself or others or if you feel

    threatened or sense that the situation may get out of control and you require additional assistance, first

    leave the scene and then contact law enforcement officers. Box 24 - 2 lists some signs of potential violence.

    As you enter a situation, approach the patient from the head (if supine) rather than from the side or the foot

    in case the person has a weapon. Don't forget that violent patients can also use items EMTs bring into the

    situation (e.g., flashlights, clipboards, and scissors) as weapons.

    ALERT!

    Use caution! Any item near the patient may become a dangerous object if the patient intends to do

    harm.

    Often violence erupts in a domestic dispute. Scenes involving interpersonal violence are highly charged

    emotionally for both the patient and the abuser, and it is essential to have law enforcement personnel on

    scene if violence is suspected. Interview and treat the patient separately if possible. If you suspect abuse to

    a spouse, child, or elder, request law enforcement assistance.

    CHAPTER 24 Behavioral Emergencies Page 8 of 16

  • Mosby's EMT-Basic Textbook - Revised Reprint, 2nd Edition

    COMMUNICATION AND EMERGENCY MEDICAL CARE

    After determining that the scene is safe, introduce yourself and explain to the patient why emergency

    medical services personnel are there (if the patient is not the one who called EMS). Then assess the patient

    for injury or illness. If there is a medical problem, perform the appropriate interventions while explaining

    everything to the patient. Assess how the patient feels and whether he or she is experiencing suicidal

    tendencies.

    Ask questions to determine whether the unusual behavior has a medical or psychological cause, although

    too much prying may provoke aggressive behavior in some individuals. Ask basic questions to assess the

    patient, such as, What is your name, the date, and your address? How do you feel? Would you like

    some help with your problem? Do you have a history of diabetes or heart disease? Usually the answers

    to simple questions such as these can help you determine the patient's psychological status.

    Observe the patient's appearance, activity, speech, and orientation for time, person, and place. If you

    suspect a drug overdose, take any drugs or medications found at the scene to the medical facility with the

    patient. Always treat the patient with respect and dignity.

    In cases of interpersonal violence in which you may suspect abuse of a spouse, child, or elder, request

    assistance from the police. Document any abuse observed or your reasons for suspecting abuse and report

    that information to the receiving medical facility. Medical providers are generally required to report

    suspected abuse, so know the laws in your state regarding the documentation and reporting of suspected

    abuse.

    CALMING THE PATIENT

    Try to calm the patient if he or she is upset, and do not leave the patient alone unless you are in danger.

    Ask all questions in a calm, reassuring manner without judging the patient. Repeat the patient's answers to

    show that you are listening. Always acknowledge how the patient feels, and do not challenge or argue with

    the individual. During questioning, remain a comfortable distance from the patient, use good eye contact,

    and do not make sudden movements. It is imperative to remain calm. Question family members and

    friends to obtain a detailed history of the patient, including medical and psychiatric illnesses. Perform an

    initial assessment of the patient, including an evaluation of mental status and the potential for violence or

    suicide.

    RESTRAINTS

    In some situations you will be unable to calm the patient sufficiently to approach and provide care safely.

    Family members often insist that the patient be taken to a medical treatment facility or that the person be

    treated for his or her own safety or well-being. Patients who cannot be calmed and who are showing

    destructive behavior toward themselves or others may need to be restrained before treatment and transport

    ( Principle 24 - 1).

    CHAPTER 24 Behavioral Emergencies Page 9 of 16

    Follow your local protocols and laws regarding restraints. In many areas restraints cannot be used without

    the cooperation of law enforcement officers or without consultation with medical direction. Some EMS

    providers may be prohibited from restraining patients under any circumstances.

    Use of restraints can be dangerous to the patient. Suffocation, poor circulation distal to the restraints, poor

    access to the airway or an injury, and poor access to the patient are medical problems that can arise from

    improper use of restraints. Never turn patients face down on the stretcher to restrain them. Numerous cases

    of suffocation have been documented in patients who were restrained in this position, in which it also is

    impossible to monitor the airway adequately or treat any changes in the patient's condition.

    PRINCIPLE 24-1 Restraining a Patient

    1. Have adequate help, including police assistance if possible.

    2. Have a plan of action.

    3. Use only necessary force.

    4. Stay beyond the patient's range of motion.

    5. Act quickly.

    6. Talk to the patient.

    7. Work with another EMT or other personnel; decide in advance how each of you will restrain a

    limb, and approach together.

    8. Secure the limbs with approved equipment, such as soft restraints.

    9. You may cover the patient's mouth with a surgical mask or an oxygen mask if the person is

    spitting or biting.

    10. Reassess the situation frequently, including the patient's vital signs and physical status.

    11. Document all your actions and the patient's actions.

    ALERT!

    Never restrain a patient face down on the stretcher.

    Fig. 24-3 Examples of soft restraints.

    CHAPTER 24 Behavioral Emergencies Page 10 of 16

  • Mosby's EMT-Basic Textbook - Revised Reprint, 2nd Edition

    You must document the patient's condition before and after applying restraints and perform several

    assessments after application. Patients experiencing a behavioral emergency may later claim injury

    because of the restraints. Once again, documentation is extremely important. Use soft leather or padded

    cloth restraints, not metal handcuffs, to avoid soft tissue damage ( Fig . 24 - 3). If applying a mask to a

    patient, use one that will not obstruct the airway or reduce oxygen flow, such as a surgical mask or an

    oxygen mask. Once restraints have been applied, do not remove them; restraints should be removed by the

    receiving facility or law enforcement officers. If the restraints are too tight when you reevaluate them, they

    should be loosened, not removed. Technique 24 - 1 describes one way to restrain a patient.

    TECHNIQUE 24-1 Restraining a Patient

    1. Four EMTs approach the patient; each EMT restrains one extremity.

    2. Place the patient supine and secure the extremities with soft restraints.

    2. Patients should be restrained in the __________ position.

    3. What should you do if you suspect abuse?

    MEDICAL AND LEGAL CONSIDERATIONS

    CONSENT

    Patients generally have the right to choose whether to be treated for their medical problem and/or

    transported to a treatment facility. Patients with behavioral emergencies represent a unique challenge in

    that they may not be competent to make decisions about their own care, particularly if they are a threat to

    themselves or others. If an emotionally disturbed patient consents to treatment and transport, the decisions

    are more easily made and the legal problems are avoided or greatly reduced.

    RESISTANCE TO TREATMENT

    Unfortunately, emotionally disturbed patients often resist treatment or transport. The patient may threaten

    to harm you or others if approached. Once again, follow local protocols regarding the care of patients who

    refuse treatment. In general, you must decide whether the patient is mentally able to make an informed

    decision. Consider the patient's psychological status, level of consciousness, age, vital signs, and injury (if

    present). A competent adult may choose to refuse treatment even after being informed of the

    consequences. See Chapter 3 for more information on consent.

    Adults showing abnormal behavior or an altered mental status may refuse treatment after being informed

    of the consequences because they do not understand the seriousness of the illness or injury. Such patients

    may be transported without consent after you contact medical supervisors. To treat or transport a patient

    without consent often requires the assistance of law enforcement officers to restrain a patient. If you are

    unsure of the mental capabilities of the patient, you should choose to treat and transport.

    USE OF FORCE

    The use of force in behavioral emergencies should be limited to reasonable force, which is the force

    necessary to keep patients from injuring themselves or others, including yourself or other personnel. Law

    enforcement officers usually are needed if force is necessary, although sometimes you also may be

    involved in the process.

    354

    355

    CHAPTER 24 Behavioral Emergencies Page 12 of 16

  • Mosby's EMT-Basic Textbook - Revised Reprint, 2nd Edition

    Use only enough force to keep the patient from injuring himself or herself or others, and avoid physical

    force that may injure the patient. Be aware that after a period of combativeness and aggression, some calm

    patients unknowingly may be provoked to cause unexpected and sudden injury to themselves and others.

    ALERT!

    Reasonable force depends on:

    1. The patient's size and strength

    2. The type of abnormal behavior exhibited by the patient

    3. The patient's mental status

    4. The method of restraint used

    DOCUMENTATION

    EMTs cannot be too cautious when dealing with an emotionally unstable patient. Documentation of all

    abnormal behavior exhibited by the patient is extremely important ( Box 24 - 3). Because patients may

    accuse EMTs of sexual misconduct, have a witness present for treatment and transport. If same-sex

    attendants are available, let them provide or assist you with care. You or your partner should never be

    alone with psychologically unstable patients.

    BOX 24-3 Important Documentation for Behavioral Emergencies

    The position in which the patient was found

    Any aggressive or abnormal action by the patient

    Anything unusual the patient says, documented in direct quotations if possible

    CHAPTER SUMMARY

    BEHAVIOR

    EMTs must be aware that any call can involve a behavioral emergency. Even if the scene size-up does not

    indicate an immediate danger, the situation may later become dangerous. A behavior is the manner in

    which a person acts or performs, including all physical and mental activity. A behavioral emergency is a

    situation in which a person exhibits abnormal or unacceptable behavior that is intolerable to the person,

    family, or community. A change in behavior may result from mental illness, situational stress, alcohol,

    drugs, medical illness, or a traumatic injury.

    ASSESSMENT AND EMERGENCY CARE

    Be aware of the danger that can arise when dealing with a behavioral emergency. Always be concerned for

    your own safety and the safety of others. Under no circumstances should you risk injury to yourself or

    others.

    Determine whether the patient is a danger to himself or herself or others and consider the need for law

    enforcement officers and restraints. Patients may have certain risk factors that predispose them to suicidal

    thoughts and tendencies.

    Perform the scene size-up first. Observe the patient's environment, attitude, and behavior. Do not let the

    patient get between you and the nearest door or exit route. Talk to family members, friends, and

    bystanders when obtaining the patient's history. If the patient cannot be managed and is a threat to himself

    or herself or others, consider the use of restraints. Follow local protocol to get approval from medical

    direction or seek the assistance of law enforcement officers before using restraints. Use only reasonable

    force when restraining a patient. Perform several assessments after applying restraints to ensure the

    patient's safety.

    Be very cautious when dealing with a behavioral emergency. Emotionally disturbed patients often refuse

    treatment or transport. You may treat a patient without consent if you believe that the patient will harm

    himself or herself or others. Document all patient behaviors and witnesses for later verification if needed.

    MEDICAL AND LEGAL CONSIDERATIONS

    It is essential that you know the local protocols and laws regarding the treatment and transport of patients

    who refuse care. In general, patients who are mentally competent can elect to refuse care. Determine

    whether the patient is mentally competent to make an informed refusal. If you are unsure, elect to treat and

    transport. Seek medical direction and assistance from law enforcement officers in difficult situations.

    Document all events in the situation so that you can legally defend any actions you took or did not take in

    the treatment of the patient.
