eHealth Exchange

The eHealth Exchange is a rapidly growing network of exchange of public and private sector partners who securely share clinical information over the Internet across the US, using a standardized approach. By leveraging a common set of standards, legal agreement and governance, eHealth Exchange participants are able to securely share health information with each other, without additional customization and one-off legal agreements. Initially, the eHealth Exchange was incubated within The Office of the National Coordinator for Health Information Technology, part of the US Department of Health and Human Services, before transitioning management to The Sequoia Project, an independent 501c3 dedicated to addressing interoperability issues, in 2012. Since then, the eHealth Exchange has more than quadrupled in size to become the nation's largest health data sharing network, supporting 109 million patients across: 
- 50 states
- 4 federal agencies (DoD, VA, HHS including CMS, and SSA)
- 65%+ of US hospitals
- 50,000+ medical groups
- 3,400+ dialysis centers
- 8,300+ pharmacies
