Abstract

Hospital readmissions are a critical concern in healthcare management. This study evaluates ensemble learning techniques using electronic health records to predict 30-day readmission risks. A dataset of over 50,000 patient records is analyzed using Random Forest, Gradient Boosting, and XGBoost models. Feature engineering techniques are applied to identify key predictors such as length of stay, comorbidities, and prior admissions. The proposed ensemble achieves an AUC of 0.81, outperforming individual models. Explainability is incorporated using SHAP values to improve clinical trust. The model enables proactive intervention strategies and supports decision-making processes in hospitals.
