To investigate the clinical and pharmacoepidemiological determinants of delirium in a psychiatric inpatient population. ⋯ These findings indicate that using conservative dosages of antipsychotic medications and minimizing the use of anticholinergic medications for parkinsonian symptoms may help to prevent delirium in psychiatric inpatients. Anticonvulsant mood stabilizers may convey less delirium risk than lithium. Antidepressant medications and sedative-hypnotics were not important determinants of delirium in this population.
