To identify risk factors for postoperative delirium (POD) following adult cardiac surgery and to develop and validate a predictive nomogram.
Key Findings:
POD occurred in 285 patients (39.4%).
Key predictors included emergency surgery, age, Sequential Organ Failure Assessment score, postoperative shock, and postoperative blood lactate and glucose levels.
The nomogram displayed strong calibration and discriminative ability in both datasets.
Interpretation:
Limitations:
The study was conducted at a single center, which may limit generalizability.
Data collection was retrospective, which may introduce biases.
Conclusion:
The study presents a validated nomogram for predicting POD in cardiac surgery patients.
