Description
Qian Wang and a large team of co-authors tested in 2026 whether hospitals can jointly train prediction models for surgery complications without pooling patient records. Delirium and kidney injury after surgery are serious risks for older patients, yet single hospitals hold limited data and privacy rules block sharing. Their simulated federation covered 7,216 patients aged sixty-five and over at five centers, with one center held out as an external check.
Three federated methods matched the accuracy of a centralized model on both outcomes, inside and outside the training group. Local-only models trailed. The authors call federated learning a workable privacy-preserving route for multicenter prediction in older surgical patients. Real deployments, beyond this simulation, remain to be proven.
