The quality of primary care services is central to reforming the healt
h care system of the United States. The well-trained generalist is ess
ential in a delivery system that emphasizes high-quality, cost-effecti
ve care. Several analyses estimate that within a few years the United
States will have 100,000-150,000 too many specialists, and some estima
tes show a shortage of perhaps 35,000 generalists. Residents and resid
ency programs in nongeneralist areas continue to increase, and two-thi
rds of graduates enter careers as specialists. Academic medical center
s must assume major responsibility for changing their programs to prod
uce the types of practitioners that U.S. society needs. Among the chan
ges recommended or directed by advisory bodies and professional organi
zations are establishing a workforce commission to set long-term goals
, limiting the number of first-year residency positions and allocating
them to generalist and nongeneralist specialties, establishing a nati
onal payment system to support residency training, setting up transiti
on payments to teaching hospitals that reduce their number of residenc
y positions, and initiatives to graduate more minority and generalist
physicians, improve geographic distribution, and expand the capacity f
or primary-care teaching.
