Paramedic Care: Principles & Practice Fourth Edition Volume 4: Medicine CHAPTER 11 Psychiatric and Behavioral Disorders Standard • Medicine (Psychiatric) ©2013 Pearson Education, Inc. Paramedic Care: Principles & Practice, 4th Ed. Competency • Integrates assessment findings with principles of epidemiology and pathophysiology to formulate a field impression and implement a comprehensive treatment/disposition plan for a patient with a medical complaint. ©2013 Pearson Education, Inc. Paramedic Care: Principles & Practice, 4th Ed. Introduction • Behavioral and psychiatric emergencies require patient history, physical exam, skilled approach to situation. • Most of your assessment and care will depend on your people skills. • Evaluate by observing behavior, gathering information from family and bystanders, and interviewing patient. ©2013 Pearson Education, Inc. Paramedic Care: Principles & Practice, 4th Ed. Behavioral Emergencies • Behavior: person's observable conduct and activity. • Behavioral emergency: behavior so unusual, bizarre, threatening, or dangerous that it alarms patient or another person. • Requires intervention of emergency service and/or mental health personnel. ©2013 Pearson Education, Inc. Paramedic Care: Principles & Practice, 4th Ed. Behavioral Emergencies • What is normal varies based on culture, ethnic group, socioeconomic class, personal interpretation, and opinion. • Normal behavior: behavior readily acceptable in a society. ©2013 Pearson Education, Inc. Paramedic Care: Principles & Practice, 4th Ed. Behavioral Emergencies • Objective factors that may indicate behavioral or psychological condition: – Interfere with core life functions (eating, sleeping, ability to maintain housing, interpersonal or sexual relations). – Pose threat to life or well-being of patient or others. – Significantly deviate from society's expectations or norms. ©2013 Pearson Education, Inc. Paramedic Care: Principles & Practice, 4th Ed. Pathophysiology of Psychiatric Disorders • 20% of population has some type of mental health problem. • As many as 1 person in 7 will require treatment for emotional disturbance. • That all people with psychiatric conditions exhibit bizarre or unusual behavior is misconception. ©2013 Pearson Education, Inc. Paramedic Care: Principles & Practice, 4th Ed. Pathophysiology of Psychiatric Disorders • Behavioral and psychiatric disorders incapacitate more people than all other health problems combined. • Most patients cared for in outpatient settings. • Only those with severe psychiatric illnesses remain institutionalized. ©2013 Pearson Education, Inc. Paramedic Care: Principles & Practice, 4th Ed. Pathophysiology of Psychiatric Disorders • Common reason for EMS intervention is patients' failure to take psychiatric medications. • Suffering from mental disorder is not reason for embarrassment or shame; society often stigmatizes these patients unfairly. ©2013 Pearson Education, Inc. Paramedic Care: Principles & Practice, 4th Ed. Pathophysiology of Psychiatric Disorders • Causes of behavioral emergencies: – Biological (or organic) – Psychosocial – Sociocultural ©2013 Pearson Education, Inc. Paramedic Care: Principles & Practice, 4th Ed. Pathophysiology of Psychiatric Disorders • Biological – Physical rather than purely psychological. – Infections and tumors; structural changes in brain such as those brought on by abuse of alcohol or drugs. – Many psychiatric conditions originate from alterations in brain chemistry. ©2013 Pearson Education, Inc. Paramedic Care: Principles & Practice, 4th Ed. Pathophysiology of Psychiatric Disorders • Psychosocial – Personal conditions: personality style, dynamics of unresolved conflict, crisis management methods. – These disorders not attributable to substance abuse or medical conditions. – Environment plays large part in psychosocial development. ©2013 Pearson Education, Inc. Paramedic Care: Principles & Practice, 4th Ed. Pathophysiology of Psychiatric Disorders • Psychosocial – Traumatic childhood incidents or parents or persons in positions of authority can impact child's development. – Dysfunctional families, abusive parents, alcohol or drug abuse by parents, or neglect can cause behavioral problems from childhood through adulthood. ©2013 Pearson Education, Inc. Paramedic Care: Principles & Practice, 4th Ed. Pathophysiology of Psychiatric Disorders • Sociocultural – Situational causes related to patient's actions and interactions within society. – Factors such as socioeconomic status, social habits, social skills, values. – Attributable to events that change patient's social space, social isolation, or impact on socialization. ©2013 Pearson Education, Inc. Paramedic Care: Principles & Practice, 4th Ed. Pathophysiology of Psychiatric Disorders • Sociocultural – Events that cause profound psychological change: Rape Assault Witnessing victimization of another Death of loved one Acts of violence such as war or riots ©2013 Pearson Education, Inc. Paramedic Care: Principles & Practice, 4th Ed. Pathophysiology of Psychiatric Disorders • Sociocultural – Events that occur over time have impact on individual: Loss of job Economic problems such as poverty Ongoing prejudice or discrimination ©2013 Pearson Education, Inc. Paramedic Care: Principles & Practice, 4th Ed. Assessment of Behavioral Emergency Patients • Order of assessment (scene size-up, primary assessment, focused history and physical examination) remains unchanged. • Interpersonal skills important for all patients; perhaps never more than for one who is experiencing a behavioral emergency. ©2013 Pearson Education, Inc. Paramedic Care: Principles & Practice, 4th Ed. Assessment of Behavioral Emergency Patients • Scene Size-Up – Approach scene carefully. – If patient experiencing behavioral emergency significant enough to warrant EMS, it is most likely significant enough to have law enforcement authorities respond. ©2013 Pearson Education, Inc. Paramedic Care: Principles & Practice, 4th Ed. Assessment of Behavioral Emergency Patients • Scene Size-Up – Most patients experiencing behavioral emergencies/crises will not attack you. – Those behaving unusually, experiencing hallucinations or delusions, under effect of substance may become violent. – Approach every patient cautiously to protect yourself and crew from injury. ©2013 Pearson Education, Inc. Paramedic Care: Principles & Practice, 4th Ed. Approach every patient cautiously. If you determine a potential for violence, request police assistance. ©2013 Pearson Education, Inc. Paramedic Care: Principles & Practice, 4th Ed. Assessment of Behavioral Emergency Patients • Scene Size-Up – Look for evidence of: Substance use or abuse. Therapeutic medications that may indicate underlying medical condition (or abuse of that medication). Signs of violence/destruction of property.

Assessment of Behavioral Emergency Patients • Primary Assessment – Be acutely suspicious of life-threatening emergencies. – Assess ABCs; intervene when necessary. – Be cautious of any overt behavior such as posture or hand gestures. – Note emotional response such as rage, fear, anxiety, confusion, or anger. ©2013 Pearson Education, Inc.
