Emergency Psychiatry

Decreasing the Clinician’s Risk

Keys to diagnosis, assessment, and management.

As with all medical emergencies, psychiatric emergencies are among the most clinically challenging situations.

Domestic violence emerges from a host of causes and motivations, and that each case deserves individual attention and solutions.

Since the time of Homer, warriors have returned from battle with wounds both physical and psychological, and healers from priests to physicians have tried to relieve the pain of injured bodies and tormented minds.1 The soldier’s heartache of the American Civil War and the shell shock of World War I both describe the human toll of combat that since Vietnam has been clinically recognized as posttraumatic stress disorder (PTSD).2 The veterans of Operation Iraqi Freedom (OIF) and of Operation Enduring Freedom (OEF) share with their brothers and sisters in arms the high cost of war. As of August 2009, there have been 4333 confirmed deaths of US service men and women and 31,156 wounded in Iraq. As of this writing, 796 US soldiers have died in the fighting in Afghanistan.3

Many refugees have been victims of severe violence that has profoundly affected their physical, psychological, and spiritual lives.

The foreword to the Textbook of Vio­lence Assessment and Management promptly reminds readers that the mental health system has been invested in the prediction and prevention of violence since its inception. In a field dedicated to promoting wellness via the management of cognition, emotion, and behavior, violent thoughts, feelings, and actions are of primary concern. When psychiatric illness or psychological distress manifests as violence, the costs in terms of human suffering are extreme, wreaking havoc in the lives of patients, clinicians, and society at large-often with irrevers­ible consequences.

Racial/ethnic and sexual orientation minorities and women historically have been relegated to social, legal, and economic disadvantage in the United States.

Emergency medicine provides care to a vast number of patients each year. In 2005, 115.3 million people visited emergency departments (EDs).

The term “domestic violence” emerged in the United States with the rise of the women’s movement in the 1970s. Before that, violence between partners was considered a private matter. A specific type of domestic violence, intimate partner violence, refers to violence between intimate partners. Public awareness campaigns help us identify one type of intimate partner violence in which one partner, typically the male partner, is the aggressor, and the other partner, typically the female, is the victim.

Agitation in older adults is frequently associated with multiple psychiatric and medical conditions and comorbidities. It commonly occurs in patients with anxiety, affective illness, psychosis, dementia, stroke, brain injury, delirium, or pain.

On a hypothetical morning, you've arrived early at your office to answer e-mails and respond to prescription requests without interruptions. The following voice mail, left for you much earlier that day, awaits your attention: "Doctor, I need to discuss my mother's behavior with you. The medications she's taking might be calming her down during the days, but she's not okay at night."

When a suicidal patient in crisis calls the psychiatrist and hears the recorded message, "If you have a 'true' emergency, go to your nearest emergency room or call 911," the patient's risk of suicide may increase.

A Public Health Approach to Intervening With Youth in Schools

Almost 3 years after the FDA warned of increased mortality in elderly patients who received atypical antipsychotics off-label for neuropsychiatric syndromes of dementia, no medication has been approved as safe and effective for this increasingly challenging problem. Recent publications, however, including a white paper from the American College of Neuropsychopharmacology (ACNP), indicate that clinical investigators are wrestling with the dilemma and considering potential alternatives to antipsychotics.

I was very pleased to read Robert Langs' letter ("Violence Against Mental Health Professionals," Psychiatric Times, July 2007), in the wake of Dr Fenton's death.

Part 1 of this article, discussed a general approach to treating psychiatric emergencies in patients with bipolar and related disorders, as well as the assessment and management of agitation and impulsive aggression. Part 2 focuses on psychosis, suicidality, and specific treatments relevant to patients in emergency settings who are agitated or have bipolar disorder.

Psychiatric emergencies usually involve some combination of agitation, aggression, impulsivity, psychosis, and risk of destructive behavior, including suicide and homicide. The psychiatrist must ensure the safety of the patient and others while identi- fying and treating immediate medical and psychiatric problems and developing and initiating a strategy for continuing the management of less immediate problems. In the diagnosis of acute behavioral disturbances, it is necessary to determine the role of the patient's primary psychiatric illnesses and any complications or treatments of those primary psychiatric illnesses, as well as the role of other medical or toxic disturbances that may be interacting with the patient's psychiatric illnesses or treatments.

Psychiatrists who work in inpatient units are faced with daily decisions about predicting which patients will be violent, both in the hospital and after discharge. These decisions are often made using unstructured clinical judgment based on the clinician's experience and knowledge of the literature. How long such judgment stays the standard of care remains to be seen, because psychiatric researchers have produced a number of assessment and management tools to improve the accuracy and use of violence risk assessment. This article briefly outlines 3 tools: the Brøset Violence Checklist (BVC), the Classification of Violence Risk (COVR), and the Historical Clinical Risk-20 (HCR-20).

In the article by Drs Kunen and Mandry, "Should Emergency Medicine Physicians Screen for Psychiatric Disorders?" (Psychiatric Times, October 2006), no mention was made of formally assessing a patient's mental status to diagnose delirium.

In The Perfect Storm, Sebastian Junger describes the desperate plight of sailors and fisherman who, in the fall of 1991, were caught out in the Atlantic Ocean as 2 powerful storms converged into 1.1 Like those mariners, emergency department (ED) clinicians find themselves at the confluence of 2 powerful trends in modern society.

The following cases highlight some of the challenges clinicians face when treating patients in whom malingerling is suspected. One key aspect of these evaluations is not overlooking signs or symptoms that point to serious illness.

The role of every emergency clinician is to determine whether the patient has a condition that threatens life or limb. Determining this in patients who malinger can be quite a challenge, because the malingering patient presents with false or exaggerated symptoms for secondary gain.

Delirium is a disorder that lies at the interface of psychiatry and medicine. It is an acute organic syndrome caused by an underlying medical condition and is defined clinically by disturbances in cognitive function, attention, and level of consciousness.1 Delirium is considered a syndrome because of the constellation of signs and symptoms associated with the disorder, coupled with a wide variety of potential etiologies.

The following case histories illustrate some of the clinical aspects of delirium that were described in the preceding article. Each case is followed by a discussion of the diagnosis, identification of the etiology, and subsequent treatment of an episode of delirium.

Once his colleagues began to recover from the shock, the death of Dr Wayne S. Fenton triggered a discussion in the professional and lay press about the risks of violence to mental health professionals posed by mentally ill patients. Fenton was found unconscious and bleeding in his office in Bethesda, Md, on Sunday, September 3, 2006. He had been beaten severely around the head and died at the scene.

Psychotic symptoms--delusions, hallucinations, paranoia, thought disorder--are mostly attributed now to aberrations in brain structure and function.

The setting of a fast-paced emergency department (ED) or psychiatric emergency service makes it especially difficult to sensitively elicit and address an individual patient's needs and concerns. When considering the myriad differences in culture that come into play between a patient and a psychiatrist or other mental health care clinician, optimal diagnosis and treatment can be even more challenging, as the cases described here illustrate. The important influence of culture cannot be stressed enough. Taking the time to understand "where the patient is coming from" can prevent an already stressful, highly emotionally charged situation from becoming even more convoluted.

If done properly, the assessment of alcohol and substance use disorders in the emergency department (ED) or psychiatric emergency service can be the first step toward recovery.

Emergency department (ED) visits have increased from 89 million in 1992 to more than 110 million in 2002, while the number of EDs decreased by about 15% during the same period. One suspected consequence of ED overcrowding is an increased tendency to disregard a psychiatric problem, especially if it is not the chief complaint.
