The System Context XGBoost model improved acute care sensitivity over clinical-only logistic regression while maintaining high specificity. The optimized model captured a larger share of total medical spending and missed less spending than the baseline model. Optimizing the classification threshold increased sensitivity but reduced specificity. Acute care utilisation was defined as at least one hospitalisation or emergency department visit during the outcome window.
