The project, still developing three weeks after the disaster, underscores the glaring reality that the hurricane destroyed medical records of untold numbers of people, possibly complicating treatment decisions for years to come.
And it's focusing new attention on the possibility of computerized medical records, accessible in an emergency even if the patient is far from home or their doctor's office no longer exists.
"There may not have been an experience that demonstrates, for me or the country, more powerfully the need for electronic health records ... than Katrina," Health and Human Services Secretary Mike Leavitt told The Associated Press on Monday.
"This is not going to be a short-term problem," he said, pledging to help Gulf Coast states rebuild better records systems.
The federal government's goal is to give most Americans computerized medical records within 10 years. But it's so expensive and technologically challenging, since systems must be compatible so the records can be read by competing clinics and hospitals, that only a fraction of health providers today are paperless.
As a result, doctors struggle to care for hurricane evacuees without knowledge of past treatments or even all the illnesses they have. Even determining daily medicines is a challenge.
"A lot of people walk in and say, 'I take a little blue pill,'" without any idea what it was, said Dr. Bethany Gardiner, a pediatrician from Santa Barbara, Calif., who is treating evacuees in Baton Rouge, La.
Last week, Dr. Joseph Mirro of St. Jude Children's Research Hospital in Memphis was reconstructing complicated chemotherapies for 80 evacuated children with cancer. Their treatments are precisely timed — they can't be just started over. He tracked down some oncologists who fled flooded New Orleans with treatment records, but relied heavily on parents' recall and own notes of their children's treatments.
"I honestly feel quite comfortable that the worst-case scenario is we delayed treatment" for some children, he said. But there was "a lot of flying by the seat of your pants to get it right."
