Primary Care in the United States: Past, Present and Future.

Even though a well-functioning primary care system is widely acknowledged as critical to population health, the number of primary care physicians (PCPs) practicing in the United States has steadily declined, and PCPs are in short supply. The reasons are multiple and include inadequate income relative to other specialties, excessive administrative demands on PCPs and the lack of respect given to primary care specialties during medical school and residency. Advanced practice nurses can augment the services of primary care physicians but cannot substitute for them. To change this situation, we need action on several fronts. Medical schools should give preference to students who are more likely to enter the primary care specialties. The income gap between primary care and other specialties should be narrowed. The administrative load placed on PCPs, including cumbersome electronic medical records, must be lessened. Insurers, including Medicare and Medicaid, must provide the resources to allow primary care physicians to act as leaders of multidisciplinary teams.
