Those are self-designated boards. They are organizations whose members come from different training programs such as neurology, neurosurgery, physical medicine and rehabilitation, psychiatry, nursing, and other areas of medicine, but who indicate an interest in pain management. Their members may be anesthesiologists who chose not to complete an optional one year fellowship in pain management. Their members could also be anesthesiologists who completed their anesthesiology training prior to the development of the one year fellowship program, but they chose not to take a written examination in order to “grandfather” into pain management certification. The ABPM and AAPM created their own certification process, but are not members of ABMS.
