Researchers have developed Fed-MedLoRA and Fed-MedLoRA+, a novel parameter-efficient federated learning framework designed to enable collaborative adaptation of large language models (LLMs) across multiple healthcare institutions. This approach addresses the challenge of data privacy and governance by transmitting only low-rank adapters, significantly reducing communication overhead compared to full model weights. Fed-MedLoRA+ further enhances this by incorporating adaptive aggregation to manage data heterogeneity and a privacy-preserving variant that applies Gaussian perturbation to adapter updates. Evaluations on clinical information extraction tasks across five patient cohorts demonstrated consistent performance improvements and better generalization compared to existing methods, including a successful case study with the Yale New Haven Health System.
