Dossia

Dossia is a Personal health record service offered by some of the largest employers in the United States. Along with Microsoft's HealthVault and Google's Google Health, Dossia is one of the largest PHR deployments in the world. Unlike the other two large PHR efforts, Dossia is based on Open Source software. Dossia cooperates with Boston Children's Hospital CHIP (Children's Hospital Informatics Program) to create the Indivo Open Source PHR. Dossia differs from traditional tethered PHR services, by providing user access to health information regardless of health plan, employer or physician. Users also have the ability to download their full record, in electronic form, at any time.

It is an initiative formed from the following companies:

• AT&T
• Applied Materials
• BP America
• Cardinal Health
• Intel
• Pitney Bowes
• Sanofi-aventis
• Walmart

Dossia is significant because it is formed by some of the largest employers in the United States with the intention of offering a PHR to its employees. Given the number of employees of these combined institutions, Dossia could be one of the largest PHR systems in the world.
