The demand for emergency psychiatric services has rapidly increased throughout the world since the 1960s, especially in urban areas. Care for patients in situations involving emergency psychiatry is complex. Individuals may arrive in psychiatric emergency service settings through their own voluntary request, a referral from another health professional, or through involuntary commitment. Care of patients requiring psychiatric intervention usually encompasses crisis stabilization of many serious and potentially life-threatening conditions which could include acute or chronic mental disorders or symptoms similar to those conditions. Symptoms and conditions behind psychiatric emergencies may include attempted suicide, substance dependence, alcohol intoxication, acute depression, presence of delusions, violence, panic attacks, and significant, rapid changes in behavior. Emergency psychiatry exists to identify and/or treat these symptoms and psychiatric conditions. In addition, several rapidly lethal medical conditions present themselves with common psychiatric symptoms. A physician's or a nurse's ability to identify and intervene with these and other medical conditions is critical. The place where emergency psychiatric services are delivered are most commonly referred to as Psychiatric Emergency Services, Psychiatric Emergency Care Centers, or Comprehensive Psychiatric Emergency Programs. Mental health professionals from a wide area of disciplines, including medicine, nursing, psychology, and social work in these settings alongside psychiatrists and emergency physicians. The facilities, sometimes housed in a psychiatric hospital, psychiatric ward, or emergency department, provide immediate treatment to both voluntary and involuntary patients 24 hours a day, 7 days a week. Within a protected environment, psychiatric emergency services exist to provide brief stay of two or three days to gain a diagnostic clarity, find appropriate alternatives to psychiatric hospitalization for the patient, and to treat those patients whose symptoms can be improved within that brief period of time. Even precise psychiatric diagnoses are a secondary priority compared with interventions in a crisis setting. The functions of psychiatric emergency services are to assess patients' problems, implement a short-term treatment consisting of no more than ten meetings with the patient, procure a 24-hour holding area, mobilize teams to carry out interventions at patients' residences, utilize emergency management services to prevent further crises, be aware of inpatient and outpatient psychiatric resources, and provide 24/7 telephone counseling. Since the 1960s, the demand for emergency psychiatric services has endured a rapid growth due to deinstitutionalization both in Europe and the United States. Deinstitutionalization, in some locations, has resulted in a larger number of severely mentally ill people living in the community. There have been increases in the number of medical specialties, and the multiplication of transitory treatment options, such as psychiatric medication. The actual number of psychiatric emergencies has also increased significantly, especially in psychiatric emergency service settings located in urban areas. Emergency psychiatry has involved the evaluation and treatment of unemployed, homeless and other disenfranchised populations. Emergency psychiatry services have sometimes been able to offer accessibility, convenience, and anonymity. While many of the patients who have used psychiatric emergency services shared common sociological and demographic characteristics, the symptoms and needs expressed have not conformed to any single psychiatric profile. The individualized care needed for patients utilizing psychiatric emergency services is evolving, requiring an always changing and sometimes complex treatment approach. As of 2000, the World Health Organization estimated one million suicides in the world each year. There are countless more suicide attempts. Psychiatric emergency service settings exist to treat the mental disorders associated with an increased risk of completed suicide or suicide attempts. Mental health professionals in these settings are expected to predict acts of violence patients may commit against themselves (or others), even though the complex factors leading to a suicide can stem from many sources, including psychosocial, biological, interpersonal, anthropological, and religious. These mental health professionals will use any resources available to them to determine risk factors, make an overall assessment, and decide on any necessary treatment. Aggression can be the result of both internal and external factors that create a measurable activation in the autonomic nervous system. This activation can become evident through symptoms such as the clenching of fists or jaw, pacing, slamming doors, hitting palms of hands with fists, or being easily startled. It is estimated that 17% of visits to psychiatric emergency service settings are homicidal in origin and an additional 5% involve both suicide and homicide. Violence is also associated with many conditions such as acute intoxication, acute psychosis, paranoid personality disorder, antisocial personality disorder, narcissistic personality disorder and borderline personality disorder. Additional risk factors have also been identified which may lead to violent behavior. Such risk factors may include prior arrests, presence of hallucinations, delusions or other neurological impairment, being uneducated, unmarried, etc. Mental health professionals complete violence risk assessments to determine both security measures and treatments for the patient.
