The $20 billion for health information technology would be, by far, the biggest government infusion to enable medical information to follow patients back and forth among doctors' offices, hospitals, and other providers. If successful, experts say, electronic medical records would improve quality, reduce duplication of services, and limit errors—ultimately saving the nation hundreds of billions of dollars each year.
