I fully admit you may not be the right person for this question, but IBM has made a lot of hay about Watson in healthcare: lots of booths and talks at industry conferences, trotting out partner medical centers, PR pieces in the Wall Street Journal, etc... Despite all the noise, I have yet to see any sort of peer-reviewed clinical study that demonstrates the application of Watson in a real healthcare setting to improve patient outcomes. Has any study like this been conducted?
We do have many actual projects with several healthcare providers. We have functioning systems (see one here https://www.youtube.com/watch?v=8lGJ0h_jAp8) and we are starting to deploy them. But the deployments are made very cautiously and in stages (and not yet broad enough for full study) because that's the nature of healthcare.
