    The study developed a predictive nomogram for postoperative delirium (POD) in cardiac surgery patients using data from 724 individuals.

  • 2

    POD occurred in 39.4% of patients, with key predictors including emergency surgery, age, and postoperative shock.

  • 3

    The nomogram demonstrated excellent discriminative ability and strong calibration agreement in both training and validation cohorts.

  • 4

    Model performance was assessed using AUROC, calibration plots, decision curve analysis, and clinical impact curve.

  • 5

    The study emphasizes the need for comprehensive risk assessment models that integrate preoperative, intraoperative, and postoperative factors.
