A dramatic shift in the postgraduate career choices of medical school gradu
ates toward primary care occurred during the mid-1990s. While some attribut
ed this shift to changes in medical school curricula, perceptions stemming
from marketplace reforms were probably responsible. For the most part, thes
e perceptions were probably generated through informal communications among
medical students and through the media. More recently, additional marketpl
ace influences, such as the consumer backlash toward managed care and unrea
lized gains in primary care physicians' personal incomes, may have fostered
contrasting perceptions among medical students, leading to career choices
away from primary care, particularly family practice. The authors offer two
recommendations for enhancing the knowledge of medical students concerning
workforce supply and career opportunities: an educational seminar in the s
econd or third year of medical school, and a public-private partnership bet
ween the Bureau of Health Professions and the Association of American Medic
al Colleges to create a national database about the shape of the primary ca
re and specialty workforces, accessible through the Internet for educators,
students, and policymakers. The authors conclude that appropriate career c
ounseling through these efficient methods could avoid future abrupt swings
in specialty choices of medical school graduates and may facilitate a more
predictable physician workforce supply.
