eHealth Exchange facilitates the sharing of continuity of care documents (CDDs). CCD exchange is based on the HL7 CDA architecture. CDA, or clinical document architecture, is a "document standard" governed by the HL7 organization. A CCD is a summary of one patient's clinical information in electronic form. A CCD gives clinicians a standard way to share a comprehensive yet concise representation of a patient's medical history and current condition.
eHealth exchange also supports additional use cases such as social security disability benefits determination and immunization notifications.
