Delirium is a common complication after cardiac surgical procedures and is associated with increased morbidity and mortality. However, whether rigorously assessed postoperative delirium is associated with an increased length of stay in the intensive care unit (LOS-ICU), length of stay (LOS), and hospital charges is not clear. ⋯ Delirium after cardiac surgical procedures is independently associated with both increased LOS-ICU and higher hospital charges. Because delirium is potentially preventable, targeted delirium-prevention protocols for high-risk patients may represent an important strategy for quality improvement.
