• Summary
DEFINITION OF PSYCHIATRIC EMERGENCY
• A clinically significant behavioral or psychological
syndrome or pattern that occurs in an individual and that
is associated with present distress or disability or with a
significantly increased risk of suffering death, pain,
disability or an important loss of freedom.
• Behavior that threatens a person’s health or safety and
the health and safety of another person
Indications of a Psychiatric Condition
• Behavior that interferes with core life
functions
• Behavior that poses a threat to the life or
well-being of the patient or others
• Behavior that deviates significantly from
society’s expectations or norms
• 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.
Pathophysiology of Psychiatric
Disorders
• 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
Assessment of Psychiatric Emergency
Patients
• Scene Size-up
– Ensure Personal Safety
• Initial Assessment
– Suspect Life-Threatening Emergencies
– Assess and Manage ABCs
– General Impression
• Consider posturing, hand gestures, and signs of aggression.
• Observe the patient’s awareness, orientation, cognitive
abilities, and affect.
• Consider the patient’s emotional state.
– Control the Scene
Assessment of Psychiatric Emergency
Patients
• Focused History and Physical Exam
– Obtain the Patient’s History
•

•
Listen.
Spend time.
Be assured.
Do not threaten.
Do not fear silence.
Place yourself at the patient’s level.
Keep a safe and proper distance.
Appear comfortable.
Avoid appearing judgmental.
Never lie to the patient.
• 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
•
Safety Guidelines for Behavioral Emergencies
• Assess the scene. If the patient is armed or has potentially harmful objects
in his or her possession, have these removed by law enforcement personnel
before you provide care.
• Be prepared to spend extra time; it may take longer to assess. Listen to, and
prepare the patient for transport.
• Have a definitive plan of action. Decide who will do what. If restraint is
needed, how will it be accomplished?
• Identify yourself calmly. Try to gain the patient’s confidence. If you begin
shouting, the patient is likely to shout louder or become more excited. A
low, calm voice is often a quieting influence.
• Be direct. State your intentions and what you expect of the patient.
• Stay with the patient. Do not let the patient leave the area, and do not
leave the area yourself unless the law enforcement personnel can and will
stay with the patient. Otherwise, the patient may go to another room and
obtain weapons, lock himself or herself in the bathroom, or take pills.
• Encourage purposeful movement. Help the patient get dressed and gather
appropriate belongings to take to the hospital.
• Express interest in the patient’s story. Let the patient tell you what
happened or what is going on now in his or her own words. However, do
not play along with auditory or visual disturbances.
• Keep safe distance from the patient. Everyone needs personal space.
Furthermore, you want to be sure you can move quickly if the patient
becomes violent or tries to run away. Do not physically talk down or directly
confront the patient. A squatting, 45 degree angle approach is usually not
confrontational; however, it may hinder your movements. Do not allow the
patient to get between you and the exit.
• Avoid fighting with the patient. You do not want to get into a power
struggle. Remember, the patient is not responding to you in a normal
manner; he or she may be wrestling with internal forces over which neither
you has control. You and others may be stimulating these inner forces
without knowing it. If you can respond with understanding to the feeling
that the patient is expressing, whether this is anger, fear, or desperation,
you may be able to gain his or her cooperation. If it is necessary to use
force, ensure that you have adequate help and move toward the patient
quietly and with assured firmness.
• Be honest and reassuring. If the patient asks whether he or she has to go to
the hospital, the answer should be, “Yes, that is where you can receive
medical help.”
• Do not judge. You may see behavior that you dislike. Set those feelings
aside, and concentrate on providing emergency medical care.

Summary
• 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.
• 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.
• 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.
• 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.
• 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.
• 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.
• 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.
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.
• 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.
• 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.
