What is HL7 CDA - the HL7 Clinical Document Architecture?
What is HL7 CDA?
Charles Parisot on CDA
The Clinical Document Architecture is a HL7 standard for the representation and machine processing of clinical documents in a way which makes the documents both human readable and machine processable and guarantees preservation of the content by using the eXtensible Markup Language (XML) standard. It is a useful an intuitive approach to management of documents which make up a large part of the clinical information processing arena.
There are plenty of HL7 CDA tools and resources, extensive HL7 CDA training and certification courses, a global workforce of HL7 CDA Experts and HL7 CDA Implementers as well as an extensive HL7 CDA Job market.

Why is CDA needed?
The Clinical Document Architecture is a HL7 standard for the representation and machine processing of clinical documents in a way which makes the documents
both human readable and machine processable and guarantees preservation of the content by using the eXtensible Markup Language (XML) standard.
It is a useful an intuitive approach to management of documents which make up a large part of the clinical information processing arena.
If CDA is not your thing, then here are more books on HL7 interoperability.

The Clinical Document Architecture is a Health Level Seven (HL7) standard for the creation of clinical documents using XML (extensible markup language).
XML is a process for adding (non-printable) characters to text
documents to allow the computer system to process the text eg. change the format
or presentation as in bolded text or to allocate specific meaning eg. storing
data or encoding data embedded in the text. An simple example (of a complex
system) would be:
The CDA specifies the structure and semantics of clinical documents in health care (Dolin R, Alschuler L. et al. 2001). A document can be defined as a piece of text or information that would usually be authenticated by a signature eg. a progress note, a pathology request, a radiology report, or an account. A CDA document may contain text, images and multimedia, coded data. The CDA document can be:
Stored either permanently or temporarily as a
document in a computer system; and
CDA was created in the recognition that much of health care is involved in creating and managing documents and the document paradigm is well understood by clinicians and administrators.
A clinical document has the following features which form the framework for the CDA.:
CDA aims to give priority to documents generated by clinicians in order to:
CDA has been developed in 3 stages: Level 1 through Level 3. Level one has a structured header and structured body of message with limited coding capacity for content. Levels 2 and 3 impose more structure to allow the representation of "context" or constrained fields and more coded data. The standard has been published for level 1 and level 2&3 are currently in draft stages.
CDA level 2&3 documents (along with the standard electronic health record architecture) require the use of templates and archetypes, which define the key information and context of complex health concepts such as family history or blood pressure.What is HL7?
