Abstract

Delirium is a common and serious altered mental state that may develop due to a wide variety of medical conditions or drug side effects. It is characterized by acute onset, fluctuating course, inattention, and disorganized thinking or altered level of consciousness. Delirium occurs commonly after surgery and is particularly common in older patients; the incidence varies widely with both patient- and surgery-specific risk factors. Perioperative delirium is associated with greater cost, longer length of stay, greater morbidity, increased likelihood of subsequent institutionalization, prolonged functional decline, and mortality.
