Five big U.S. employers launched a computerized health record system for employees on Wednesday that they hope will help set a standard for America's messy health care system, and save money and lives.
Patients would control who can see their records, which they can access even if they change jobs or doctors.
The five companies will make the system -- which will store an individual's information on a secure Web site -- available to their 2.5 million employees and retirees next year.
