Would a doctor dressing neatly affect your rating?

If you're looking to go out for dinner, see a movie or plunk down big bucks on a new TV, chances are you'll look online for help with the decision.

Lots of people are now checking out potential doctors that way, too. Online ratings are becoming part of how many Americans shop for a physician, according to a study in the latest issue of JAMA, the journal of the American Medical Association.

Among more than 2,100 people who took part in an online survey, 59 percent said that online doctor ratings were either somewhat important or very important in making a decision about which doctor see.

You'd probably like to know how good a doctor is at diagnosing and treating what ails you. Accurate assessments of the quality of care are hard to come by.

Still, Dr. Ashish Jha, a health policy researcher at the Harvard School of Public Health, says we're in the very early days of consumer ratings for doctors.

"There is a clear consensus that Medicare is going to start doing for physician practices what it has been doing for hospitals," he says. The

Medicare's Hospital Compare isn't easy to use, but it's already bringing data based on quality to the masses. And now Medicare's Physician Compare is working on adding quality data about large group practices of doctors to the online mix.
