The Argonaut Project has a big, maybe even audacious ambition: to make health data-sharing easier by using Internet-based open messaging and documents standards instead of complex, healthcare-specific ones. The project's champion, John Halamka, is one of the best-known figures in health information technology. He's the CIO of Beth Israel Deaconess Medical Center, a full professor at Harvard Medical School, the chairman of the New England Health Electronic Data Interchange Network (NEHEN), co-chair of the HIT Standards Committee, and a practicing emergency physician. Under his leadership, in 2012 Beth Israel Deaconess was the No. 1 company in InformationWeek's innovation ranking. His Life as a Healthcare CIO blog is a "must read" for any serious follower of the health IT landscape.
