The American Medical Association (AMA) and the Association of American Medical Colleges (AAMC) maintain a database of information on graduate medical education (GME) training programs accredited by the Accreditation Council for Graduate Medical Education (ACGME) and of the residents and fellows in them. In the spring, this database of residents has added to it the approximately 21 000 new residents who match into programs through the National Resident Matching Program, as well as new residents who did not match, the latter information collected through the AAMC's follow-up report of US medical schools. The AMA and the AAMC together administer the annual National GME Census through GME Track, an Internet-based AAMC product. From May until December 2011 all directors of programs accredited by the ACGME were asked to complete the Census on GME Track. Information about the training programs supplied by the program directors is added to FREIDA Online, an Internet-based public information source on GME programs that is available to medical students and resident physicians. In July 2011 program directors were surveyed about their active, transferred, and graduated residents and fellows for academic year 2011-2012. Program directors were provided with lists of residents and fellows from the current database and were asked to (1) confirm or modify the training status of trainees who were present in their programs the prior year; (2) add new physicians to their program who were not already in our database; and (3) confirm, edit, or add demographic information on all trainees. This demographic information includes sex, birthdate, country of birth, citizenship status, and race/ethnicity.
