Untangling the Electronic Health Data Exchange
]]

The purpose of this post is to help a non-technical audience untangle some of the confusion regarding health data exchange standards, and particularly come to a better understanding of the similarities and  differences between the Continuity of Care Record (CCR) standard and the CDA Continuity of Care Document (CCD). But what I’m most interested in is getting beyond the technical, political, or economic positions and interests of the proponents of any particular standard to arrive at some principles that demonstrate in plain language what we are trying to achieve by using such standards in the first place.

The HL7 Version 3 Clinical Document Architecture (CDA®) is a document markup standard that specifies the structure and semantics of "clinical documents" for the purpose of exchange between healthcare providers and patients. It defines a clinical document as having the following six characteristics: 1) Persistence, 2) Stewardship, 3) Potential for authentication, 4) Context, 5) Wholeness and 6) Human readability.

Health Level Seven or HL7 refers to a set of international standards for transfer of clinical and administrative data between software applications used by various healthcare providers. These standards focus on the application layer, which is "layer 7" in the OSI model. The HL7 standards are produced by Health Level Seven International, an international standards organization, and are adopted by other standards issuing bodies such as American National Standards Institute and International Organization for Standardization.

Hospitals and other healthcare provider organizations typically have many different computer systems used for everything from billing records to patient tracking. All of these systems should communicate with each other (or "interface") when they receive new information, or when they wish to retrieve information, but not all do so.
