Less than 25% of doctors are members of the AMA. I am not totally aware of everything they do but in the public sector they negotiate the EBAs for doctors in public hospitals. They also have some training but the major training is done through the specialist colleges that you mention as they run accreditation for those craft groups.Is the AMA more of a Union or is it a professional association like CPA? How does it relate to the various Colleges (of Surgeons, gps etc) what percentage of doctors are members?
There are plenty of doctors I know who have no time for the AMA.
