Delirium in hospitalized adults: Situation critical, no relief available
Date:7/6/2009

INDIANAPOLIS Every year as many as seven million adults in the United States experience delirium during hospitalization. In a systematic review of the scientific literature on delirium prevention and treatment, investigators from Indiana University School of Medicine, the Regenstrief Institute and Wishard Health Services found that despite the significant health and financial burdens of delirium for hospitalized adults, no effective way to prevent or treat the condition has been identified.

"Having delirium prolongs the length of a hospital stay, increases the risk of post-hospitalization transfer to a nursing home and doubles the risk of death. We need to identify a safe and effective drug to prevent and treat delirium.

Delirium is not dementia, but individuals with dementia are more susceptible to developing delirium during hospitalization than individuals without dementia.

The researchers found that only 13 randomized controlled studies on promising drugs for delirium were conducted from January 1966 to October 2008. These studies identified and evaluated 15 drugs including first and second generation antipsychotics, the drugs currently prescribed by most physicians for patients with delirium. The researchers found that neither older agents nor newer, more expensive medications were effective in preventing del
