A health care system is only as good as the people working in it. The most valuable resource in health care is not the latest technology or the most state-of-the-art facility, but the health care professionals and other workers who are the human resources of the health care system.
In this chapter, we discuss the nation's three largest health professions—nurses, physicians, and pharmacists, as well as a closely linked profession, physician assistants (Table 7–1). What are the educational pathways and licensing processes that produce the nation's practicing physicians, nurses (including nurse practitioners), pharmacists, and physician assistants? How many of these health care professionals are working in the United States, and where do they practice? Do we have the right number? Too many? Too few? How would we know if we had too many or too few? Are more women becoming physicians? Are more men becoming nurses? Is the growing racial and ethnic diversity of the nation's population mirrored in the racial and ethnic composition of the health professions? To answer these questions, we begin by providing an overview of each of these professions, describing the overall supply and educational pathways. We then discuss several cross-cutting issues pertinent to all these professions.

Health maintenance organizations (HMOs) wanted more primary care physicians, not more specialists. Almost none of the fourth-year students applied to anesthesiology residency programs that year. Susan started to think more about becoming a primary care physician. ...
