There is a saying in medical diagnosis: "When you hear hoofbeats behind you, don't expect to see a zebra". https://secure.wikimedia.org/wikipedia/en/wiki/Zebra_%28medi... Most patients have common problems that are fairly easy for experienced physicians to diagnose. So there is no point to entering a bunch of data into Watson just to get back the same answer you already know. But it could certainly be helpful for those rare edge cases where the physician can't figure out the "zebra", or where the patient hasn't responded as expected to treatment.
