Just who is entitled to be called "doctor" in hospitals, medical offices and other clinical settings is being considered by the State Board of Medical Examiners. Under a proposal before the board, physician assistants with doctoral degrees would be barred from using the title in clinical settings. Board member Kevin Walsh, a physician assistant, said the rule would help ease confusion among patients. "I think this is an issue, especially now that there are so many different providers, I think people should be clear as to who the providers are," Walsh said at the February 12 board meeting.
