Health Informatics — Clinical document registry federation

A federation of clinical document registries (CDRs) provides a view that the entire set of member CDRs can be seen as a single CDR. This document defines a logical structure for the federation of CDRs that does not require any conformance criteria. It provides use cases and sets out a list of basic functional recommendations and configuration parameters for CDR federations.

This document covers aspects of federations of CDRs including cases where the whole content of a CDR has been replicated in another CDR of the same federation.

Main sections:

· Scope

· Recommendations for federation

· Modes of federated replication

· Use case: Clinical document sharing via regional federation without replication

· Use case: Clinical document sharing via regional federation with replication

· Use case: National federation of hospitals for research purposes with replication
