Background:

Postoperative delirium (POD) is a frequent complication in elderly patients undergoing cardiac surgery, impacting short- and long-term prognoses.
Early identification of POD risk factors is crucial for optimizing perioperative management in surgical patients.

Discussion:

This study evaluated five machine learning (ML) models to predict POD risk in cardiac surgery patients.
The random forest (RF) model demonstrated superior performance compared to SVM, RBFNN, KNN, and KRR.

Key Insights:

The incidence of POD in the study cohort was 28.6%.
The RF model achieved high accuracy (87.99%), sensitivity (69.27%), specificity (95.38%), MCC (70.00%), and AUC (0.9202).

Outlook:

Computational ML models, especially RF, show significant clinical utility for early POD risk identification in cardiac surgery.
Further research can explore integrating these models into clinical workflows to personalize patient care and reduce delirium incidence.
