Core Tip

Core Tip: Our study develops a predictive model for postoperative delirium in elderly patients with abdominal malignancies, using the synthetic minority oversampling technique. This model highlights key risk factors including the Charlson comorbidity index, anesthesia grade, cerebrovascular disease history, surgical duration, perioperative transfusion, and postoperative pain. Its validation demonstrates effectiveness in clinical settings, enhancing care and outcomes for this high-risk group.
