The management of delirium is an important and challenging facet of therapy when dealing with critically ill patients. Delirium has been shown to be an independent predictor of increased mortality at six months and longer length of stay in patients who are ventilated in intensive care.1 It is also associated with increased length of hospital stay and may predispose
patients to prolonged neuropsychological disturbances after they leave intensive care.2,3 These factors contribute to the higher intensive care and hospital costs attributed to patients with delirium.4
