In this position paper, the American College of Physicians Task Force
on Physician Supply examines the current and future roles of the ideal
general internist. Discussed are the characteristics shared by all in
ternists, whether engaged in general or subspecialty practice; current
trends and the growing crisis in the supply of primary care physician
s; and the practices and patient characteristics of both general inter
nists and family physicians. The Task Force considered four options fo
r the future general internist but rejected them because they either m
aintained the status quo or were retrogressive: 1) allowing the commun
ity-based general internist to disappear; 2) strengthening the general
ist's identity as a primary care-oriented physician who provides no su
bspecialty care; 3) becoming hospital-based generalists who act princi
pally as consultants; or 4) becoming fully trained subspecialists who
also provide primary care. The Task Force proposes a new definition th
at reaffirms fundamental characteristics of today's general internists
and adds characteristics that should be the hallmark of the general i
nternist of the future. The paper describes characteristics that are s
hared by other generalist physicians and those that are distinctive to
today's general internist. It then addresses characteristics that wil
l be needed to prepare for the environment of medical care in the futu
re. The new definition reaffirms that the general internist is an expe
rt in the general care of the adult, but it also revives the concept o
f the general internist as a local authority on a specific topic in wh
ich he or she has special expertise. The paper concludes with a discus
sion of some of the questions that its definition poses for graduate m
edical education. The Task Force suggests that changes in the educatio
nal system to produce the desired mix of skills required for the gener
al internist of the future will increase the attractiveness of general
internal medicine.
