Federated Learning Across Hospitals is an area of active development in applied machine learning, with evidence that has
accumulated unevenly across its component questions. We review the current evidence base for federated learning across
hospitals, spanning methodological, implementation, governance, and cost dimensions, focusing on where practice has converged
and where it continues to vary, and set out the practical considerations relevant to a team considering its adoption. We conclude
that selective, context-specific use is best supported by the evidence currently available, rather than uniform adoption or
avoidance
