Predictors and outcomes of delirium

Identification and treatment of patients with depressive symptoms, alcohol use and cognitive impairment prior to AAA surgery could reduce the incidence of postoperative delirium and the prolonged hospital stays and impaired functional status associated with it. Surgeons should consider using simple screening instruments before surgery to identify patients at risk and referring them for psychiatric evaluation and treatment. They should also consider including psychiatrists early in the care of high-risk patients to improve detection of and early intervention for delirium.
