In patients who are elderly and patients in the postoperative period, delirium may result in a prolonged hospital stay, increased complications, increased cost, and long-term disability. [17]

According to one study, delirium is associated with worse survival and greater resource consumption in those with cardiac critical illness. Among 590 patients included, the prevalence of cardiac (C)ICU delirium was 20.3%. Delirious patients were older, had greater disease severity, required longer ICU stays (5 vs 2 days; P< .001), and had higher mortality (27% vs 3%; P< .001). [18]
