Aging, primary care, and self-sufficiency: health care workforce challenges ahead.

A combination of "environmental factors" in the U.S. has led to an increased demand for health care professionals. However, there has been a significant decrease in the number of U.S. medical graduates selecting careers in family medicine and general internal medicine, thus driving demand for international medical graduates. At the heart of our national workforce policy needs to be good domestic and foreign policies, such as self-sufficiency approaches that include strategies to incentivize rural and underserved practice for U.S. medical graduates.
