Project:  This project was aimed at validating and demonstrating the feasibility, methodology and technology of the proposed health care solution.

 

The Dossia partners, who also include Applied Materials, AT&T, Pitney Bowes, Cardinal Health and Sanofi-Aventis, ultimately hope to extend the PHR to more than a million employees and dependents.

 

The DOSSIA system is proposed to help cut down on medical errors and eliminate waste.

The objective was to improve the quality of the care patients receive and reduce inefficiency in the health care system.

The key feature of DOSSIA is that it is personal and private. Patient chooses how much data is collected in a record and shared - with whom, and in what form.
