CDA is flexible enough to be compatible in a wide range of environments, and can be stored as a document in a computer system (permanently or temporarily) or can be transmitted as the content of a message. Transport methods can include HL7 V2, HL7 V3, DICOM, MIME-encoded attachments, HTTP, or FTP. Implementation of CDAĬDA does not specify a transport mechanism and can be utilized within a messaging environment or outside of it.

In short, any document that might have a signature is a viable document for CDA. Text, images, and even multimedia can be included in the document.Ī CDA document could be, for example, any of the following: discharge summary, referral, clinical summary, history/physical examination, diagnostic report, prescription, or public health report.

A mandatory free-form portion enables human interpretation of the document, while an optional structured part enables electronic processing (like with an EMR system). This is due to its use of XML language, which also allows the standard to be broken into two different parts. It was known earlier as the Patient Record Architecture (PRA).ĬDA is a flexible standard and is unique in that it can be read by the human eye or processed by a machine. CDA conforms to the HL7 V3 Implementation Technology Specification (ITS), is based on the HL7 Reference Information Model (RIM), and uses HL7 V3 data types. Documents can include discharge summaries, progress notes, history and physical reports, and those who had adopted ASTM CCR.CDA is an XML-based, electronic standard used for clinical document exchange that was developed by Health Level Seven.

The Continuity of Care Document ( CCD) is built using HL7 Clinical Document Architecture (CDA) elements and contains data that is defined by the ASTM Continuity of Care Record (CCR). CCDA is explicitly technically specified in the laws.įurthermore, what does C CDA mean? The Consolidated Clinical Document Architecture ( C- CDA, or CCDA), is based on components of two standard formats that were required for EHRs in previous certification situations: Continuity of Care Record (CCR) Continuity of Care Document (CCD).ĬDA documents can be transported using HL7 version 2 messages, HL7 version 3 messages, IHE protocols such as XDS, as well as by other mechanisms including: DICOM, MIME attachments to email, http or ftp. It was built as a different type of standard ( CDA) for different types of documents. In practice it's just a CCD with extra stuff at this point. The CCDA is actually Consolidated Clinical Document Architecture. Moreover, what is the difference between CDA and CCDA? Clinical Document Architecture ( CDA) is a popular, flexible markup standard developed by Health Level 7 International (HL7 ) that defines the structure of certain medical records, such as discharge summaries and progress notes, as a way to better exchange this information between providers and patients.
