Dossia. Drove many healthcare investments over his career with Intel, where he was CEO from 1998 until 2005 and recently retired as Chairman. These include establishing Intel's Digital Health Group, on-site clinics at Intel campuses, and Dossia, his largest in ambition. A nonprofit consortium of employers, it seeks to promote an open source infrastructure for exchanging patient data, plus a universal personal health that won't be controlled by a single vendor (read: Google or Microsoft). Formed in 2006, includes AT&T, BP America, Intel, sanofi-aventis, Wal-Mart, Vanguard, and others. Each member has contributed millions to "the cause" but objective progress is hard to measure. Still, credit for this powerful (and many thought, unlikely) assembly is Barrett's. It could be used to leverage many additional innovative efforts.

Testifying before U.S. Senate on healthcare in 2008:

"Given the coming age and chronic [illness] tsunami...the old one-on-one physician to patient paradigm will not suffice. We need to move away from physician-centered care [and] toward a patient centric model where delivery and funding are channeled via care teams with a community approach."
