Harvard project to scan millions of medical files

Harvard scientists are building a powerful computer system that will use artificial intelligence to scan the private medical files of 2.5 million people at local hospitals, as part of a government-funded effort to find the genetic roots of asthma and other diseases.
The $20 million project -- which would probe more deeply and more quickly into medical records than human researchers are capable of -- is designed to find links between patients' DNA and illnesses. Although the effort could raise concerns about privacy, researchers say the new program, called ''I2B2" (for ''Informatics for Integrating Biology and the Bedside") would respect the strict guidelines set out in federal and state laws, and could be a powerful tool for many kinds of research.
Hospitals gather huge amounts of information from patients each day -- from blood tests to chest X-rays and brain scans. For decades, researchers have pored through these records and gleaned insights that have helped millions of Americans. Now, the Harvard team hopes to put far more information at the fingertips of researchers, and to speed the process with sophisticated automation.
