Dr Watson: How IBM’s supercomputer could improve health care

Watson, the IBM supercomputer that defeated the world’s best “Jeopardy!” players this year, has found a job in medicine. It won’t be consulting with patients, but a version of the game-show champion could appear in examination rooms, offering assistance to flesh-and-blood physicians. But how soon might you see Dr. Watson? And could Dr. Watson be better than your doctor?

I’ve worked in software development for more than 25 years — never for IBM — and was amazed by Watson’s ability to understand language, solve problems and present answers in the form of a question as Alex Trebek coolly looked on. While I don’t think most doctors need to worry about their jobs anytime soon, Watson-esque technology offers a powerful diagnostic tool that could bring dramatic benefits to health care. The prospect of a robotic caregiver might not seem comforting, but Watson’s first appointment will be a watershed moment. This is an app way beyond anything on an iPhone.

Machine learning — the technology that makes Watson, well, Watson — lets software analyze historical data and generate rules that inform decision-making, even when tasks significantly vary. Watson could churn through millions of case histories to learn what diagnosis is likely to be correct and what treatment would be the most effective. The system could almost instantly process medical textbooks, electronic medical records and the latest published research, illuminating obscure links among studies in seemingly unrelated specialties. Watson could someday be a standard diagnostic tool. Its ability to make sense of a universe of data would be far beyond that of any person or team of experienced physicians.

Watson could dazzle in the exam room. It could lead to greater consistency of care, giving every patient an exhaustive review of treatment options. It’s a good bet that this smart machine will evolve into a genuine Dr. Watson: a true diagnostic partner for physicians, offering not just a reference but a viable second opinion.

  1. You don’t need a doctor if you have God.

  2. …brought to you by IBM, the same company that developed custom-designed punch cards cards used by the Nazis to track, control murder millions in their slave labor camps.

  3. Usually, to get into med school in the US (if you are an American; foreign students get a hand-up and probably a hand-out), you have to have political pull. Simple as that. It starts in prep schools with the usual school politics in play. I have personally watched as a brilliant student was denied appointment to a medical doctorate program because of who he was (or wasn’t), not because of his potential. He went on to earn a masters degree in engineering with a specialty in devising artifical limbs.

    He was a good man; perhaps the ptb found that threatening.

  4. TOTAL LUNACY… INSANITY…
    The descriptive input to a computer … cannot over-ride doctors personal observations…that result in hunches… bedside manners…personal compassion…etc etc etc
    Watson should be a boat anchor.

  5. Ive been going to docs for 5 years over some stuff. They just think im making up the blood I cough up and show them. Watson will help these (mostly) overpaid kindergarten flunkies tie their shoes as well so they don’t trip running down the hall to cut someone open to remove a tool they left in them last month.
