Predicting patient health outcomes accurately is a key challenge in modern healthcare, significantly impacting treatment planning, patient management, and healthcare resource allocation. In this study, we propose an innovative approach for predicting patient health outcomes using federated machine learning (FedML), a novel machine learning technique that enables collaborative learning from decentralized data sources while ensuring privacy. This research advances current methodologies by enabling data analysis across diverse health institutions without explicit data sharing. The goal is to develop a robust model capable of capturing a wide spectrum of health factors impacting patient outcomes, thus potentially leading to more accurate predictions. Our approach integrates data from multiple healthcare institutions to train a global predictive model, iterating between local model training and global model aggregation until convergence. We also employ a privacy-preserving mechanism to ensure the sensitive health data remains within the original institution, alleviating privacy and data security concerns inherent in traditional centralized learning methods. We compared our federated learning method with traditional machine learning approaches, including deep learning, support vector machines, and random forests, using a set of diverse patient datasets. Results show our approach improves prediction performance, generalizability, and scalability while preserving data privacy. The study concludes by discussing the potential of federated learning in transforming predictive modeling in healthcare and addressing key challenges in implementing this approach. This research contributes to the body of knowledge in predictive health informatics and provides a roadmap for implementing federated machine learning in healthcare applications.
