A Clinical Exchange Document or CED is a generally accepted format of patient data that is used to share information between systems. CCR and Medical Summary (a CDA) are the two CED formats that we support in V11. CED is an Allscripts term to cover all the different formats we support. Both are xml documents, and both are essentially encounter summaries containing allergies, medications, immunizations, problems, vitals, results. These extracts can be printed or saved as an xml document. The xml document can be imported into other TouchWorks systems or other EHR's that support the format. CCD Documents CCD documents combine the benefits of the CCR with the CDA specifications. From the HL7 CCD Handbook - The HL7 Clinical Document Architecture (CDA) is an XML-based markup standard intended to specify the encoding, structure and semantics of clinical documents for exchange. CDA is part of the HL7 version 3 standard. CDA documents are persistent in nature. The CDA specifies that the content of the document consists of a mandatory textual part (which ensures human interpretation of the document contents) and optional structured parts (for software processing). The structured part relies on coding systems (such as from SNOMED and LOINC) to represent concepts. From Wikipedia - CCD was developed as a collaborative effort between ASTM and HL7, combining the benefits of ASTMs Continuity of Care Record (CCR) and the HL7 Clinical Document Architecture (CDA) specifications. It is intended as an alternate implementation to the one specified in ASTM ADJE2369 for those institutions or organizations committed to implementation of the HL7 Clinical Document Architecture.
