IntroductionIntroduction

• The mind and body are inseparable.

− Illness affects a person’s behavior.

− Changes in mental state affect physical health.

Definition of Behavioral Emergency


• Most experts define behavior as the way

people act or perform.

− Overt behavior is generally understood by those

around the person.

− Covert behavior has hidden meanings or intentions.



• Behavioral

emergency

− Some disorder of

mood, thought, or behavior that

interferes with

ADLs

• Psychiatric

emergency

− Behavior that

threatens a person’s health or

safety and the

health and safety

of another person



• A behavioral or psychiatric emergency is

defined by the person who dials 9-1-1.

• It can be difficult to understand the patient’s

confused and frayed feelings.

PrevalencePrevalence

• Average number of mentally unhealthy days

for Americans has increased

− 1993: 2.9 days/month

− Today: 3.5 days/month

• 45.1 million US adults with any mental

illness in the past year

Medicolegal Considerations Medicolegal Considerations

• When behavior, speech, and thoughts are

erratic, it can be difficult to communicate.

− Spend time with the patient.

− Obtain consent when possible.

− Be clear in your explanations.

Causes of Abnormal BehaviorCauses of Abnormal Behavior

• Four broad categories

− Biologic or organic in nature

− Resulting from the environment

− Resulting from acute injury or illness

− Substance-related


• Biologic or organic

− Organic brain syndrome

− Conditions alter the functioning of the brain


• Environmental

− Psychosocial and sociocultural influences

• When consistently exposed to stressful events

patients develop abnormal reactions.

• Sociological factors affect biology, behavior, and

responses to the stress of emergencies.


• Injury and illness

− Illness results in

stress on coping

mechanisms.

− Acute trauma

creates stress.

• Post-traumatic

stress disorder

(PTSD)

• Substance-related

− Alcohol

− Cigarettes

− Illicit drugs

− Other substances

Psychiatric Signs and Symptoms


• When mental health is challenged,

mechanisms or behaviors work to return

homeostasis.

− Present as psychiatric signs and symptoms

Patient AssessmentPatient Assessment

• Assessment of the patient with a behavioral

emergency differs from other methods.

− You are the diagnostic instrument.

− The assessment is part of the treatment.

Scene Size-UpScene Size-Up

• Situations with a strong behavioral

component may have a sudden and

unexpected turn of events.

− Determine whether it is dangerous to you and

your partner.


• The environment can give clues.

− Social history

− Living conditions

− Availability of support

− Activity level

− Medications

− Overall appearance

− Attitude/well-being

Primary AssessmentPrimary Assessment

• Clearly identify yourself.

• Form a general impression.

− Assess appearance, posture, and pupils.

− Limit the number of people around the patient.

− Stay alert to potential danger.


• Airway and breathing

− Assess the airway and evaluate breathing.

− Provide interventions based on your findings.


• Circulation

− Assess the pulse rate, quality, and rhythm.

− Obtain systolic and diastolic blood pressures.

− Evaluate for shock and bleeding.

− Assess the patient’s perfusion level.


• Transport decision

− Disturbed patients should see a physician.

− If a patient withholds consent, they may be

taken against their will at the request of:

• Police

• County mental health physician


• Transport decision (cont’d)

− The same applies to the use of forcible restraint.

• Law enforcement officers should be summoned.

• Consult medical command as necessary.

History TakingHistory Taking

• Mental status

examination

− Key part of

assessment

− Check each system using

COASTMAP.

COASTMAPCOASTMAP

• Consciousness

− Level

− Concentration

• Orientation

− Year/month

− Location

• Activity

− Behavior

− Movement

• Speech

− Rate, volume, flow, articulation,

and intonation

COASTMAPCOASTMAP

• Thought

− Is the patient

making sense?

• Memory

− Recent

− Remote

− Immediate

• Affect and mood

− Do the inner

feelings seem

appropriate?

• Perception

− “Do you hear

things others

can’t?”

Secondary AssessmentSecondary Assessment

• Obtain vital signs.

• Examine skin temperature and moisture.

• Inspect the head and pupils.

• Note unusual odors on the breath.

Secondary AssessmentSecondary Assessment

• In examining the extremities, check for:

− Needle tracks

− Tremors

− Unilateral weakness or loss of sensation

ReassessmentReassessment

• Routinely performed during transport

• Your radio report should include:

− Medical and mental health history

− Medications prescribed

− Assessment findings

− Information from the mental status examination

ReassessmentReassessment

• Discuss with the hospital the need for

restraints or medications.

− If the patient is aggressive or violent, provide

advance notice to the emergency department.

Emergency Medical CareEmergency Medical Care

• If the erratic behavior could be caused by a

medical disorder:

− Treat that before presuming the behavior is due

to an emotional or psychiatric cause.

Communication TechniquesCommunication Techniques

• Begin with an

open-ended

question.

• Let the patient talk.

• Listen, and show

that you are

listening.

− Respiratory rate

• Be prepared to support ventilation.

Pathophysiology, Assessment, and Management of Specific EmergenciesPathophysiology, Assessment, and Management of Specific Emergencies

• Many factors

contribute to

disturbances of

behavior.

Acute PsychosisAcute Psychosis

• Pathophysiology

− Person is out of touch with reality

− Occur for many reasons

− Episodes can be brief or last a lifetime.


• Assessment

− Characteristic: profound thought disorder

− A thorough examination is rarely possible.

− Transport the patient in an atraumatic fashion.

− Use COASTMAP.


• Consciousness

− Awake and alert

− Easily distracted

• Orientation

− Disturbances more common in

organic disorders

• Activity

− Most commonly

accelerated

• Speech

− Neologisms


• Thought

− Disturbed in

progression and

content

• Memory

− Relatively or

entirely intact

• Affect and mood

− Mood is likely to

be disturbed.

− Affect may reflect

mood or be flat.

• Perception

− Auditory

hallucinations


• Management

− Reasoning doesn’t always work.

− Explain what is being done.

− Directions should be simple and consistent.

− Keep orienting the patient.


• Management (cont’d)

− Before pharmacologic treatments, try:

• Maintaining an emotional distance

• Explaining each step of the assessment

• Involving people the patient trusts


• Management (cont’d)

− When methods fail, it may be appropriate to:

• Safely restrain the patient.

• Administer a medication to help the behavior.

Agitated DeliriumAgitated Delirium

• Pathophysiology

− Delirium: a state of global cognitive impairment

− Dementia: more chronic process

− Patients may become agitated and violent.

Agitated DeliriumAgitated Delirium

• Assessment

− Try to reorient patients.

− Perform a thorough assessment.

• Management

− Identify the stressor or metabolic problem.

Suicidal IdeationSuicidal Ideation

• Pathophysiology

− Suicide: any willful act designed to end one’s

life


• Assessment

− Every depressed

patient must be

evaluated for

suicide risk.

− Most patients are relieved when the

topic is brought up.


• Assessment (cont’d)

− Broach the subject in a stepwise fashion.

− Higher-risk patients include patients who have:

• Made previous attempts

− Acknowledge the patient’s feelings.

− Encourage transport.

Patterns of Violence, Abuse, and Neglect


• Abuse and neglect

− Assess the following:

• The patient

• The environment

• Other persons involved

− Document your findings, and report your concerns according to local protocols.



• Violence

− Most angry patients can be calmed by a trained

person who conveys confidence.

− EMS personnel should prepare to deal with

hostile or violent behavior.

• Preventive action is best to ensure no harm.



• Identify situations with the potential for

violence.

− Preventive action starts with being prepared for

a possible violent encounter.

− Develop “survival awareness.”



• Risk factors

− Scenarios including:

• Alertness

• Elevated mood

• Increased motor

and speech

activities

Problems Associated with Medication NoncomplianceProblems Associated with Medication Noncompliance

• Increases the likelihood that a person with

mental illness will commit a violent act

• When obtaining medication history, include:

− Previously prescribed medications

− Missed doses

Emergency Use of MedicationsEmergency Use of Medications

• Emergency use of medications are often

required with violence.

− The potential danger is too great not to

intervene.

Emergency Use of MedicationsEmergency Use of Medications

• Before administering chemical restraint,

complete your assessment with:

− A thorough understanding of the chief complaint

− Attention to allergies

− Medical and medication history

Pediatric Behavioral ProblemsPediatric Behavioral Problems

• 50% of childhood

mental illnesses

will present by age

14 years.

− More likely to have

coexisting

problems

− Difficult to diagnose

Pediatric Behavioral ProblemsPediatric Behavioral Problems

• Mental status assessment is similar to that

of an adult.

− Exception: Consider developmental level.

• Abnormal findings are often related to

adjustment disorders and stress.

Geriatric Behavioral ProblemsGeriatric Behavioral Problems

• Distress and pain

may be caused by:

− Exposure to new

experiences

− Alterations to routines

© Leah-Anne Thompson/ShutterStock, Inc.

Geriatric Behavioral ProblemsGeriatric Behavioral Problems

• Anxiety and depression are too often

considered a “normal part of aging.”

− Ageism: discrimination against older people

• Take stock of your own attitudes.

SummarySummary

• Behavioral emergencies can present unique

challenges in patient management. Focus

on reducing the patient’s stress without

exposing yourself to unnecessary risks.

• A behavioral or psychiatric emergency is

any reaction to events that interferes with

activities of daily living.

SummarySummary

• Behavioral emergencies can be a

temporary response to a traumatic event.

• Calls for behavioral emergencies have

special medical and legal considerations.

• You have limited legal authority to require a

patient to undergo care in the absence of a

life-threatening emergency. Always involve

law enforcement personnel when you are

called to assist a patient with a severe

behavior or psychiatric crisis.

SummarySummary

• If a patient poses an immediate threat,

leave the area until law enforcement

personnel secure the scene.

• Underlying causes of behavioral

emergencies fall into four categories:

biologic (organic) causes, causes resulting

from the person’s environment, causes

resulting from acute injury or illness, and

causes that are substance related.

SummarySummary

• Psychiatric signs and symptoms occur

when mental health is challenged and

psychological mechanisms or behaviors

mobilize to return the person’s mental state

to homeostasis.

• Assessment of a disturbed patient differs

from other assessment methods in that you

are the diagnostic instrument. Assessment

is also part of the treatment.

SummarySummary

• When providing care, be direct, honest, and

calm; have a definitive plan of action; stay

with the patient at all times; and express

interest in the patient’s story.

• When sizing up the scene, pay special

attention to potential dangers and objects

that may be used as potential weapons,

hazardous chemicals, etc. Remove

potentially harmful objects.

SummarySummary

• Primary assessment includes identifying

yourself, forming a general impression of

the patient’s condition and the nature of the

problem, assessing the ABCs, making a

decision about transport, and taking a

history via the mental status examination.

• Secondary assessment involves looking for

signs of an organic cause of the behavioral

emergency.

SummarySummary

• Management is focused on ensuring scene

safety and maintaining awareness of life-

threatening conditions, while treating the

patient for any medical disorders.

• Effective communication techniques include

beginning with an open-ended question,

showing that you are listening, allowing

silence when appropriate, avoiding

argument, facilitating communication, and

asking questions.

SummarySummary

• Crisis intervention skills include staying

calm and being direct, excluding disruptive

people from the scene, maintaining a

nonjudgmental attitude, developing a plan

of action, encouraging motor activity, and

assuming that the patient can hear and

understand everything you say.

• Use of chemical or physical restraints is

reserved for times when verbal intervention

fails to reduce severe agitation.

SummarySummary

• Pathophysiologic factors that contribute to

behavioral disturbances include cognitive

impairment, thought disorders, mood

disorders, neurotic disorders, substance-

related disorders and addictive behavior,

somatoform disorders, factitious disorders,

impulse control disorders, and personality

disorders.

SummarySummary

• You may encounter patients with psychosis,

a thought disorder characterized by a statue

of delusion in which the person is out of

touch with reality.

• You may encounter patients with agitated

delirium. This is impairment of cognitive

function that can present with disorientation,

hallucinations, or delusions, and is

characterized by restless and irregular

physical activity.

SummarySummary

• The threat of suicide requires immediate

intervention. Depression is the most

significant risk factor for suicide.

• Situations involving violence, abuse, and

neglect can have the potential for escalation

and the possibility of evoking emotional

responses in you.

SummarySummary

• Patients with psychiatric emergencies may

be taking any of several types of

psychotropic drugs. During assessment,

determine which medications have been

prescribed and whether the patient is

actually taking them.
