How the Computer That Won 'Jeopardy!' Could Change Medicine

At FutureMed, IBM's doctors explained how Watson could improve quality of care, reduce errors, and help doctors better utilize skills.


FutureMed featured back-to-back sessions from Dr. Paul Grundy, and Watson guru Dr. Marty Kohn. We'll give you a rundown of both of their presentations here:

Grundy, IBM's global director of health care transformation, is a proponent of a primary-care model called the "Patient Centered Medical Home." Grundy explained that he developed the model by looking for the pain and suffering in the current health care delivery system and working to change it in "profoundly different ways."

Earlier, when looking at the U.S. health care system, Grundy came to the conclusion that "we in the United States were dead last and we were dead last at twice the price of any other civilized nation on the face of the earth. And it has just gotten worse since then."

But he noticed that there were places around the U.S. where one was significantly more likely to get the level of care that one could get in, say, Switzerland or Australia. Dubuque, Iowa, is an example of that, he said. Dubuque is one of the least expensive health care markets in the country.

Not surprisingly, Grundy explained that he had received questions from the IBM CFO about the regional cost of care in the U.S., which the company was considering when deciding where to locate jobs. As it turns out, IBM decided to locate a call center in Dubuque -- partly as a result of the low health care costs there.

And when looking at the costs of various health care markets, Grundy noticed "tremendous waste." Depending on which economist one listens to, administrative costs and overhead make up 19 to 30 percent of the health care costs, he said.

When asked what kind of health care they wanted, IBM employees stressed the importance of the relationship with physicians. "We decided that we really fundamentally wanted to change the covenant between the buyer and the provider of care," Grundy said. "And that is happening today."

While the U.S. has some of the best partial care in the world, the country is poor at coordinating care. "We do not know how to play as a team," Grundy said.

As a solution, Grundy put forward the concept of the Patient-Centered Medical Home, which emphasizes collaboration. The system has been backed by Anthem, Wellpoint, and government agencies such as the Department of Defense.

Grundy explained that, in a recent study with IBM employees, the new delivery system model resulted in the following gains in efficiency, which he ascribes to "robust prevention in primary care:"

  • 36 percent drop in hospital days
  • 32 percent drop in ER use
  • 9.6 percent drop in total cost

Another study by CareMore that tried out the Patient-Centered Medical Home model found the following:

  • a hospitalization rate 24 percent below average
  • hospital stays 38 percent shorter
  • an amputation rate among diabetics 60 percent lower than average
  • these improved outcomes have come without increased total cost

Next, Kohn, chief medical scientist of care delivery systems at IBM Research, gave the audience at FutureMed an in-depth look at the medical applications of Watson, which famously bested human competition in Jeopardy! about a year ago. "Our goal, with [Paul Grundy]'s leadership, is to understand what is necessary to support the transformation of health care to the patient-centered evidence-based outcome-based system that actually makes people healthy and reduces cost," Kohn said.
