To estimate prospectively the incidence of delirium in psychiatric inpatients and to identify risk factors for delirium in this population. ⋯ Delirium is an uncommon incident event in the psychiatric inpatient population. The incidence rate reported here may be useful as a benchmark for the identification of excessive rates in other inpatient settings. Since delirium is sometimes related to modifiable therapeutic factors, an excessive rate should prompt a search for its causes.
