A study claims 90% of Wikipedia entries on common medical problems contain a mistake. But does that mean we should give up on the user-edited Internet encyclopedia when it comes to self diagnosis?

Dr. Elmer Bernstam, a professor at Houston's UT Health School of Biomedical Informatics, says he's studied online forums and found them to be pretty accurate.

"If a false information made it on to the forum then it was generally corrected by a subsequent posting quite reliably."

Dr. Bernstam says we shouldn't give up on Wikipedia based on one study.

"The absence of discussion may be one reason that Wikipedia may be less accurate than forums. But I think we need more work than this one paper to discount Wikipedia."

Dr. Bernstam says many of the Wikipedia entries may contain a false statement, but that doesn't mean the entire entry is false.
