Malpractice information is available on your state Board of Medicine's website, if they have one.
Such as in North Carolina :

You can such under Disciplinary Reports to see if actions have been taken by the Med Board against a specific Physician and why...
I agree with Sahuaro there are way to many frivolous lawsuits, so unless an action was taken by the Medical Board against the Physician, I wouldnt put a ton of credence into a civil suit.
Hope that helps...
