вЂњContext: A clinical document establishes the default context for its contents.вЂќ.

вЂњPotential for authentication: A clinical document is an assemblage of information that is intended to be legally authenticated.вЂќ.

вЂњStewardship: A clinical document is maintained by an organization entrusted with its care.вЂќ.

вЂњPersistence: A clinical document continues to exist in an unaltered state, for a time period defined by local and regulatory requirementsвЂ¦вЂќ.

CDA defines a clinical document as having the following characteristics: 4

Clinical Document ArchitectureД¬linical Document Architecture, Release 2 (CDA R2) is a specification for the exchange of electronic clinical documents. When NLP needs to know the specific subject of a section, CDA4CDT helps because it defines clinical documents down to the section and sometimes to the element level.

3 NLP needs to know what is a section, so CDA helps because it defines the sections and subsections within a document. The syntax of CDA is Extensible Markup Language (XML), which makes this division between data and metadata explicit. In short, NLP needs to know what is data and what is metadata. CDA has a rigorous context model that states that the CDA header defines the context for the complete document unless explicitly overridden within the body, section, or data element within the document. These familiar linguistic structures provide a context for information, and context is a critical factor in differentiating whether вЂњdischargeвЂќ is from a nose, and therefore a symptom, or from a hospital, in which case it signifies an end to a patient encounter. 2Д¬uriously, the aspects of language that are taught at the earliest age-how to recognize a sentence, a section, a paragraph-can be the most difficult from an NLP perspective. 1 Today, the majority of critical patient information is unstructured in narrative notes, so CAC through NLP holds great promise, and it is in this area where the clinical document architecture (CDA) and the project known as CDA4CDT (clinical document architecture for common document types) have a role to play. How CDA4CDT Supports CACД¬AC uses either structured input or natural language processing (NLP).
