TUESDAY, March 29, 2016 (HealthDay News) -- Antipsychotic medications do not appear to be effective for preventing or treating delirium in adult medical or surgical inpatients, according to a review published online March 23 in the Journal of the American Geriatrics Society.

Karin J. Neufeld, M.D., M.P.H., from Johns Hopkins University in Baltimore, and colleagues conducted a systematic review and meta-analysis to examine the effectiveness of antipsychotic medications in preventing and treating delirium. Data for adult surgical and medical inpatients from 19 studies were reviewed.

The researchers observed no significant effect on delirium incidence in seven studies that compared antipsychotics with placebo or no treatment for delirium prevention after surgery (odds ratio, 0.56; 95 percent confidence interval, 0.23 to 1.34). Antipsychotic use was not associated with change in duration, severity, or hospital or intensive care unit length of stay, using data from all 19 studies; significant heterogeneity was seen among the studies. There was no correlation with mortality (odds ratio, 0.90; 95 percent confidence interval, 0.62 to 1.29).

"Current evidence does not support the use of antipsychotics for prevention or treatment of delirium," the authors write. "Additional methodologically rigorous studies using standardized outcome measures are needed."
