The Challenge
Traditional sepsis prediction models suffer from critical limitations: data privacy concerns prevent centralized data pooling, lack of model interpretability hinders clinician trust, and poor generalizability limits real-world clinical adoption across diverse hospital settings.
Our Advanced Solution
We propose a hybrid FL-XAI framework that integrates federated learning with ensemble-based machine learning (Random Forest, LightGBM, XGBoost, K-Nearest Neighbors, Logistic Regression) and explainable AI techniques (SHAP, LIME, PDP). This decentralized approach trains models on local data, preserving privacy, while offering transparent and clinician-oriented decision support.

Case Study: Enhancing Sepsis Detection in a Multi-Hospital Network
Scenario: A regional hospital network, facing increasing sepsis mortality rates and stringent data privacy regulations, sought an AI solution for early detection. Centralized data pooling was not feasible due to privacy concerns and institutional autonomy. Traditional black-box AI models lacked the transparency required for clinical adoption.
Solution Applied: The network implemented the hybrid FL-XAI framework. Each hospital autonomously trained ensemble ML models (Random Forest, LightGBM) on its local patient data, which was preprocessed using SMOTE for class balancing. Model updates, not raw data, were securely aggregated centrally via federated learning. Integrated SHAP and LIME provided clinicians with real-time, interpretable insights into each prediction, explaining the contributing factors for sepsis risk.
Outcome: The FL-XAI framework achieved a 98.50% accuracy in federated sepsis prediction, enabling earlier, more informed clinical decisions. This led to a significant reduction in sepsis-related complications and mortality, all while maintaining full patient data privacy and increasing clinician trust in AI-driven diagnostics. The scalable and privacy-aware nature of the solution made it ideal for multi-institutional deployment.
