The nation's ambulance crews are pushing a virtual medical ID system to rapidly learn a patient's health history during a crisis—and which can immediately text-message loved ones that the person is headed for a hospital. The Web-based registry, invisibleBracelet.org, started in Oklahoma and got a boost this fall when the state's government made the program an optional health benefit for its own employees. Now the Invisible Bracelet attempts to go nationwide as the American Ambulance Association next month begins training its medics, who in turn will urge people in their communities to sign up.
