The hardest thing in medical diagnosis/treatment for a computer to do is not running algorithms to determine diagnosis/treatment; it's taking the patient history. If you ask a patient if he has had any abdominal pain, a lot of patients think about it and decide they have had abdominal pain. It may just have been some slight discomfort from gas a couple of weeks ago, but doc asked so it must be important; wouldn't want to leave anything out. Other patients are stoic and wouldn't really call that raging appendicitis "pain", more like "discomfort". An experienced doc should be able to read the patient and tell these apart. Watson? Maybe someday. As with most tasks in medical analytics, the rate limiting factor is the data.
