Here are three physicians who have filed suits against their former employers since Nov. 15:. 1. Otolaryngologist Yi Kao, MD, sued his former employer, State College, Pa.-based Mount Nittany Medical Center, for allegedly wrongly terminating his privileges. His privileges were terminated in June when the state issued a subpoena after a staff member reported Dr. Kao’s hands trembled during a procedure and he had complained of vision issues.
