Delirium during psychiatric admission increases mortality in psychiatric patients during and after hospitalization. A nationwide study from 1995 through 2012

Delirium occurring in psychiatric inpatients is associated with elevated mortality. Sedative-hypnotic agents are commonly involved in drug-related delirium. Particular preventative effort is warranted for patients with a previous history of delirium, as we found approximately 40% with more than one episode of delirium.
