Family physicians' declining contribution to prenatal care in the United States.

A substantial decline in prenatal care by family physicians has occurred over the past 20 years in all geographic regions of the country. Even so, during the past two decades, family physicians and general practitioners (FP/GPs) have provided more than 2 million prenatal visits per year. As the field re-explores future scope, it should consider the erosion of the provision of prenatal care, its effect on the U.S. population and the specialty, and possibilities for revitalization of prenatal care in residency curricula and practice.
