By the year 2025, the United States will be short 124,000 to 159,000 physicians, the American Medical Association predicts.

Indeed, the doctors say, medical schools turn away many qualified candidates. But the problem comes after medical school, when students search for residencies. The number of U.S. medical school graduates is increasing, but the number of residency positions isn't keeping pace due to a lack of funding, the doctors say.
