Applied Materials Inc., British Petroleum America Inc., Intel Corp., Pitney Bowes Inc. and Wal-Mart Stores Inc. are funding a nonprofit institute to develop "Dossia," a Web-based electronic health record that can be used for storing health information on the 2.5 million employees, dependents and retirees who have health insurance through one of the five companies.

The companies hope the electronic record -- which will be available to employees in mid-2007 -- will help eliminate medical errors, duplicate testing and other causes that increase health care costs.

Employers so far have been AWOL in the ongoing effort to help support the adoption of electronic medical records nationally, said Craig Barrett, chairman and CEO of Intel. But, he added, the rising costs are now beginning to affect the ability of companies to successfully compete.

"Think of [the initiative] as American industry getting involved in health care," Barrett said. "If we're paying half of the [health care] bill in the U.S. ... we want to get a more effective return on that investment. Medical costs cannot continue to grow faster than inflation. We employers are looking at it as putting a cap on health care [spending]."

Omnimedix Institute, a nonprofit organization in Portland, Ore., will develop Dossia. J.D. Kleinke, chairman and CEO of Omnimedix, describes Dossia as a "hypersecure medical Internet" being designed by people who have experience building IT security for banking systems. Users can enter information into the Dossia system, or it will gather health information on behalf of the requesting users and store it in a database, Kleinke said. Neither the employers nor any insurance company will have access to the information, according to the founding members.
