Intensive Care Units (ICUs) are critical environments where timely and accurate decision-making can significantly impact patient survival. Traditional scoring systems like APACHE and SOFA often fall short in adapting to complex, nonlinear patient data and real-time changes. This research introduces an AI-based mortality prediction system that leverages machine learning algorithms—including LSTM, XGBoost, and Logistic Regression—trained on large-scale ICU datasets such as MIMIC-III and eICU. The model uses a comprehensive set of features including vital signs, lab results, and patient demographics to estimate the likelihood of mortality within 24 hours of ICU admission. Evaluation metrics like AUC, accuracy, and precision demonstrate high performance, particularly with deep learning models. Additionally, SHAP-based interpretability ensures model transparency for clinical use. The system aims to support healthcare professionals by offering early warning alerts, aiding rapid intervention, and improving ICU workflow efficiency. The findings suggest that machine learning can serve as a powerful tool in reducing mortality rates and optimizing care in intensive care settings.
