IBM’s Watson, the Jeopardy!-playing supercomputer that scored one for Team Robot Overlord two years ago, just put out its shingle as a doctor or, more specifically, as a combination lung cancer specialist and expert in the arcane branch of health insurance known as utilization management. Thanks to a business partnership among IBM, Memorial Sloan-Kettering and WellPoint, health care providers will now be able to tap Watson’s expertise in deciding how to treat patients.
WellPoint’s chief medical officer Samuel Nussbaum said at the press event today that health care pros make accurate treatment decisions in lung cancer cases only 50% of the time (a shocker to me). Watson, since being trained in this medical specialty, can make accurate decisions 90% of the time. Patients, of course, need 100% accuracy, but making the leap from being right half the time to being right 9 out of ten times will be a huge boon for patient care.
The best part is the potential for distributing the intelligence anywhere via the cloud, right at the point of care. This could be the most powerful tool we’ve seen to date for improving care and lowering everyone’s costs via standardization and reduced error.
Watson doesn’t tell a doctor what to do, it provides several options with degrees of confidence for each, along with the supporting evidence it used to arrive at the optimal treatment. Doctors can enter on an iPad a new bit of information in plain text, such as “my patient has blood in her phlegm,” and Watson within half a minute will come back with an entirely different drug regimen that suits the individual. IBM Watson’s business chief Manoj Saxena says that 90% of nurses in the field who use Watson now follow its guidance.
