Development of Perioperative Delirium Prediction Model

Postoperative delirium is an acute organic brain dysfunction that is commonly observed following cardiovascular surgery. It presents with acute and fluctuating changes in the level of consciousness, resulting in impaired cognitive function and perception. The incidence of delirium following cardiac surgery has been reported to range from 11.4% to 55%. In light of the challenges associated with treating delirium once it has manifested, it is imperative to prioritise the early recognition and prevention of this condition. The objective of this study was to develop a perioperative delirium risk prediction model for patients undergoing cardiovascular surgery.
