Doctors in Chicago are asking patients to sign “no frivolous lawsuit” contracts:

Sixteen doctors at a women’s health clinic in the northwest suburbs have begun using an aggressive new tactic to fend off malpractice suits.

Patients at four WomanCare offices are being asked to sign a contract promising not to file “frivolous” malpractice suits.

Some patients have asked questions about the form, said WomanCare CEO Dr. Carl Cucco. “But no one has refused to sign,” he said.

Anyone who does refuse still would be treated.

Cucco said the contract levels the playing field in malpractice litigation. “We want to play fairly, and most patients are very supportive.”
