"While previous projections showed a baseline shortage of 39,600 doctors in 2015, current estimates bring that number closer to 63,000, with a worsening of shortages through 2025."
"Medical colleges and hospitals warn that these efforts will hit a big bottleneck: There is a shortage of medical resident positions. The residency is the minimum three-year period when medical-school graduates train in hospitals and clinics. There are about 110,000 resident positions in the U.S., according to the AAMC. Teaching hospitals rely heavily on Medicare funding to pay for these slots. In 1997, Congress imposed a cap on funding for medical residencies, which hospitals say has increasingly hurt their ability to expand the number of positions."
