Evaluation of discontinuation of atypical antipsychotics prescribed for ICU delirium.

A number of trials suggest that short-term use of atypical antipsychotics may be useful in the treatment of delirium associated with critical illness. However, long-term use of such agents for this indication has not been studied and may be associated with risks of adverse effects as well as unnecessary health care costs. A retrospective study of prescribing patterns of atypical antipsychotics initiated for the treatment of intensive care unit (ICU) delirium was performed to identify whether these agents were being discontinued prior to or upon hospital discharge.
