Da Vinci Clinical Data Exchange (CDex) Implementation Guide

The Clinical Data exchange (CDex) is part of the larger Da Vinci use case for Health Record exchange (HRex).
The scope of the CDex project is to defined combinations of exchange methods (push, pull, subscribe, CDS Hooks, ), specific payloads (Documents, Bundles, and Individual Resources), search criteria, conformance, provenance, and other relevant requirements to support specific exchanges of clinical information between provider and other providers and/or payers. The goal is to identify, document and constrain very specific patterns of exchange so that providers and payers can reliably exchange information for patient care (including coordination of care), risk adjustment, quality reporting, identifying that requested services are necessary and appropriate (e.g. should be covered by the payer) and other uses that may be documented as part of this effort. Clinical data payloads will include C-CDA, C-CDA on FHIR, compositions, bundles, specific resources, and bulk data exchange. This list is intended to be illustrative and not prescriptive.
