IBM supercomputer Watson now being offered to doctors to diagnose patients

Dr. Watson is accepting new patients. The Watson supercomputer
is graduating from its medical residency and is being offered
commercially to doctors and health insurance companies, IBM said Friday.
IBM
Corp., the health insurer WellPoint Inc. and Memorial Sloan-Kettering
Cancer Center announced two Watson-based applications - one to help
diagnose and treat lung cancer and one to help manage health insurance
decisions and claims.
Both applications take advantage of the
speed, huge database and language skill the computer demonstrated in
defeating the best human "Jeopardy!" players on television two years
ago.
Armonk-based IBM said Watson has improved its performance by 240 percent since the "Jeopardy!" win.
In
both applications, doctors or insurance company workers will access
Watson through a tablet or computer. Watson will quickly compare a
patient's medical records to what it has learned and make several
recommendations in decreasing order of confidence.

In
the cancer program, the computer will be considering what treatment is
most likely to succeed. In the insurance program, it will consider what
treatment should be authorized for payment.
Watson (actually
named for IBM founder and not the Sherlock Holmes' friend, Dr. Watson)
has been trained in medicine through pilot programs at
Indianapolis-based WellPoint and at Sloan-Kettering in New York.
Manoj
Saxena, an IBM general manager, said the supercomputer has ingested
1,500 lung cancer cases from Sloan-Kettering records, plus 2 million
pages of text from journals, textbooks and treatment guidelines.
It
also learned "like a medical student," by being corrected when it was
questioned by doctors and came up with wrong answers, Saxena said in an
interview.

"Watson is not making the decisions" on treatment or authorization,
Saxena said. "It is essentially reducing the effort for doctors and
nurses by going through thousands of pages of information for each
case."
The lung cancer program is being adopted by two medical
groups, the Maine Center for Cancer Medicine and WestMed in New York's
Westchester County. Saxena said it should be running at both groups by
next month.
WellPoint itself is already using the insurance
application in Indiana, Kentucky, Ohio and Wisconsin. It will be selling
both applications - at prices still to be negotiated - and will
compensate IBM under a contract between the two companies, an IBM
spokeswoman said.
WellPoint said using Watson should not increase insurance premiums because of savings from waste and errors.
