Clinical application of psychiatry in emergency settings

Emergency psychiatry is the clinical application of psychiatry in emergency settings. 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.

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. The individualized care needed for patients utilizing psychiatric emergency services is evolving, requiring an always changing and sometimes complex treatment approach. There are countless more suicide attempts. Psychiatric emergency service settings exist to treat the mental disorders associated with an increased risk of 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. 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. Patients with a personality disorder will usually not complain about symptoms resulting from their disorder. Patients with an emergency phase of a personality disorder may showcase combative or suspicious behavior, have brief psychotic episodes, or be delusional. Compared with outpatient settings and the general population, the prevalence of individuals with personality disorders in inpatient psychiatric settings is usually 7–25% higher. Clinicians working with such patients attempt to stabilize the individual to their baseline level of function. Different forms of psychiatric medication, psychotherapy, or electroconvulsive therapy may be used in the emergency setting. The introduction and efficacy of psychiatric medication as a treatment option in psychiatry has reduced the utilization of physical restraints in emergency settings, by reducing dangerous symptoms resulting from acute exacerbation of mental illness or substance intoxication. A common route of administration is oral administration, however if this method is to work the drug must be able to get to the stomach and stay there. as well as assorted benzodiazepines are the most frequently used drugs in emergency psychiatry, especially agitation.

Other treatment methods may be used in psychiatric emergency service settings. Brief psychotherapy can be used to treat acute conditions or immediate problems as long as the patient understands his or her issues are psychological, the patient trusts the physician, the physician can encourage hope for change, the patient has motivation to change, the physician is aware of the psychopathological history of the patient, and the patient understands that their confidentiality will be respected. The process of brief therapy under emergency psychiatric conditions includes the establishment of a primary complaint from the patient, realizing psychosocial factors, formulating an accurate representation of the problem, coming up with ways to solve the problem, and setting specific goals. The information gathering aspect of brief psychotherapy is therapeutic because it helps the patient place his or her problem in the proper perspective. If the physician determines that deeper psychotherapy sessions are required, he or she can transition the patient out of the emergency setting and into an appropriate clinic or center.

Electroconvulsive therapy is a controversial form of treatment which cannot be involuntarily applied in psychiatric emergency service settings. Instances wherein a patient is depressed to such a severe degree that the patient cannot be stopped from hurting himself or herself or when a patient refuses to swallow, eat or drink medication, electroconvulsive therapy could be suggested as a therapeutic alternative. While preliminary research suggests that electroconvulsive therapy may be an effective treatment for depression, it usually requires a course of six to twelve sessions of convulsions lasting at least 20 seconds for those antidepressant effects to occur.

There are other essential aspects of emergency psychiatry: observation and collateral information. The observation of the patient's behavior is an important aspect of emergency psychiatry as it allows the clinicians working with the patient to estimate prognosis and improvements/declines in condition. Many jurisdictions base involuntary commitment on dangerousness or the inability to care for one's basic needs. Observation for a period of time may help determine this. For example, if a patient who is committed for violent behavior in the community, continues to behave in an erratic manner without clear purpose, this will help the staff decide that hospital admission may be needed. Collateral information or parallel information is information obtained from family, friends or treatment providers of the patient. Some jurisdictions require consent from the patient to obtain this information while others do not. For example, with a patient who is thought to be paranoid about people following him or spying on him, this information can be helpful discern if these thoughts are more or less likely to be based in reality. Past episodes of suicide attempts or violent behavior can be confirmed or disproven.

Patient receive emergency services often on a time limited basis such as 24 or 72 hours. After this time, and sometimes earlier, the staff must decide the next place for the patient to receive services. This is referred to as disposition. This is one of the essential features of emergency psychiatry.

The staff will need to determine if the patient needs to be admitted to a psychiatric inpatient facility or if they can be safely discharged to the community after a period of observation and/or brief treatment. Initial emergency psychiatric evaluations usually involve patients who are acutely agitated, paranoid, or who are suicidal. Initial evaluations to determine admission and interventions are designed to be as therapeutic as possible.

Involuntary commitment, or sectioning, refers to situations where police officers, health officers, or health professionals classify an individual as dangerous to themselves, others, gravely disabled, or mentally ill according to the applicable government law for the region. After an individual is transported to a psychiatric emergency service setting, a preliminary professional assessment is completed which may or may not result in involuntary treatment. Some patients may be discharged shortly after being brought to psychiatric emergency services while others will require longer observation and the need for continued involuntary commitment will exist. While some patients may initially come voluntarily, it may be realized that they pose a risk to themselves or others and involuntary commitment may be initiated at that point.

In some locations, such as the United States, voluntary hospitalizations are outnumbered by involuntary commitments partly due to the fact that insurance tends not to pay for hospitalization unless an imminent danger exists to the individual or community. In addition, psychiatric emergency service settings admit approximately one third of patients from assertive community treatment centers. Therefore, patients who are not admitted will be referred to services in the community.
