Post-hoc analysis reveals cognitive status as a key predictor of postoperative delirium in cardiac surgery, emphasizing the need for neurocognitive assessment.
Key Points
Baseline cognitive status was the only significant predictor of postoperative delirium, highlighting its importance in patient evaluation.
In models lacking cognitive status, both postinduction frontal alpha power and neurofilament light concentration significantly predicted postoperative delirium.
Multivariable regression models demonstrated that including cognitive status renders other predictors ineffective in estimating postoperative delirium risk.
A total of 220 patients undergoing elective cardiac surgery were assessed for postoperative delirium using neurocognitive tests and EEG.
