Clinical policy: critical issues in the diagnosis and management of the adult psychiatric patient in the emergency department.
AHRQ discusses (1) In the alert adult patient presenting to the emergency department (ED) with acute psychiatric symptoms, should routine laboratory tests be used to identify contributory medical conditions (nonpsychiatric disorders)? (2) In the adult patient with new-onset psychosis without a focal neurologic deficit, should brain imaging be obtained acutely? (3) In the adult patient presenting to the ED with suicidal ideation, can risk-assessment tools in the ED identify those who are safe for discharge? (4) In the adult patient presenting to the ED with acute agitation, can ketamine be used safely and effectively?
