Psychiatric emergencies in the elderly.

Psychiatric disorders are best managed by interdisciplinary teams of psychiatrists, psychiatric nurses, social workers, and psychologists. Some Emergency Departments have access to such psychiatric services either in the hospital or in associated clinics or community mental health centers. Unfortunately, many are not staffed with mental health professionals or such expertise is available only on a limited basis, particularly on evenings and weekends. Therefore, one or more members of the Emergency Department staff should have specialized psychiatric training and experience. We have reviewed the format for conducting a psychiatric history and mental status examination and have discussed the most common emergency psychiatric disorders of the elderly and their management in the Emergency Department. In order to assess and treat elderly psychiatric patients properly, emergency personnel must be aware of the medical disorders associated with psychiatric illness and must be prepared to initiate treatment quickly and appropriately. For most patients, emergency intervention is the first step in ensuring that a correct diagnosis is made and that ongoing psychiatric treatment is arranged through timely consultation and referral.
