Dr. Tayoun said the main demands from doctors in his state include setting caps on non-economic damages at $250,000, as well as setting limits on contingency fees for lawyers involved in medical malpractice cases.

"We would like to see limits on how much attorneys can take," he said, explaining that lawyers' contingency fees can take away 30-to-40 percent of jury awards in addition to charges for the lawsuit costs.

The group said many doctors planning to participate in next week's events have cancelled their non-elective surgeries, office visits and other routine care scheduled during the protest. But the group promised that physicians would not leave emergency patients at risk and that emergency rooms would remain open, with doctors on call.

Tonight, some physicians planning to participate in rallies will attend meetings to discuss final details and learn more about managing their offices and handling the media, the group said.

Dr. Tayoun said Pennsylvania has been designated a "code blue" state by the American Medical Association in terms of its medical liability insurance crisis and that patients in his state have already lost 1,100 physicians due to rising medical malpractice insurance costs.

"We need to stop the hemorrhaging before one more physician is forced out of business," he said.
