Architecture of Health Information Infrastructure: The Case of the United States of America

The Health Infrastructure in the U.S. is called the National Health Information Network (NHIN) which is composed of regional Health Information Exchange (HIE) hubs. This approach has been exercised since 2008. However, there is a lack of one top-down comprehensive architecture of this system, which is being developing by each state individually. This paper provides the top-down model of such architecture, perhaps the first one which is made. The paper defines basic components of that system. Also some issues of security and privacy of stored and exchanged data are disputed. By the end, the paper provides conclusions regarding the issues of its implementation.
