Problem

We run federated machine learning across hospital networks for clinical trial research. Each hospital has patient data we're not allowed to move - privacy law and patient consent don't permit central aggregation. We need to train models and compute population statistics across data that is physically distributed across 40 hospitals in 8 countries, each with different EHR systems and data formats. Design a data pipeline that makes this possible.

Summary

Patient data stays local. Insights have to be global.
