Commentary: Why primary care doctors are fed up

(CNN) -- Health policy experts agree that any reform in our health care system must include a well-educated, caring primary care doctor who is able to manage the health of his or her patients with an eye to using resources optimally to keep costs down.

That's a tall order and it seems that few policy makers realize the value of primary care physicians.

People are making a huge assumption in this reform effort that as we extend coverage to millions who don't have health insurance, there will be doctors there to actually provide the health care. Fewer and fewer medical students are choosing primary care and many primary care doctors are leaving the field.

Let me share with you why we are losing so many primary care doctors. What follows are a few examples I experience each week...

...No one is talking about this on the national level. If they don't address these issues, then good luck having physician assistants provide the safety net with two years of training. Good luck getting newly trained physicians once they see our salaries. Good luck finding internists in your community with only 1 percent of medical students going into internal medicine.

Good luck recruiting primary care specialists when we are projected to be short 39,000 by 2020, according to the American Academy of Family Physicians. And nearly half of all doctors surveyed by the Physicians' Foundation have said that over the next three years they plan to reduce the number of patients they see or stop practicing entirely.
