A new model incorporates complex health data to better predict complications after major surgeries, enhancing surgical decision-making and patient safety.

• Complication prevalence: 8% ICU admission, 4% mechanical ventilation, 7% acute kidney injury, and 1% in-hospital mortality.
• Model performance: AUROC scores of 0.93 for ICU admission, 0.94 for mechanical ventilation, 0.92 for acute kidney injury, and 0.95 for in-hospital mortality.

Understanding which variables influence these outcomes, particularly procedure type and clinician factors, can refine patient selection.
