Hey, did you know adding millions of regular patients to the health care system while not increasing the number of doctors can actually lead to a shortage of physicians? Democrats in Washington either didn’t know or didn’t care. Either way, we’re left screwed.

Experts warn there won’t be enough doctors to treat the millions of people newly insured under the law. At current graduation and training rates, the nation could face a shortage of as many as 150,000 doctors in the next 15 years, according to the Association of American Medical Colleges.

That shortfall is predicted despite a push by teaching hospitals and medical schools to boost the number of U.S. doctors, which now totals about 954,000.

The greatest demand will be for primary-care physicians. These general practitioners, internists, family physicians and pediatricians will have a larger role under the new law, coordinating care for each patient.

In fact, the number of individuals entering medical school dropped by more than a quarter from 2002 to 2007. How have Democrats in Washington responded? By adding millions of new patients to the rolls and complaining about the salaries doctors collect. Good strategy.

Meanwhile, a number of new medical schools have opened around the country recently. As of last October, four new medical schools enrolled a total of about 190 students, and 12 medical schools raised the enrollment of first-year students by a total of 150 slots, according to the AAMC. Some 18,000 students entered U.S. medical schools in the fall of 2009, the AAMC says.

But 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.

Medicare pays $9.1 billion a year to teaching hospitals, which goes toward resident salaries and direct teaching costs, as well as the higher operating costs associated with teaching hospitals, which tend to see the sickest and most costly patients.

Doctors’ groups and medical schools had hoped that the new health-care law, passed in March, would increase the number of funded residency slots, but such a provision didn’t make it into the final bill.

“It will probably take 10 years to even make a dent into the number of doctors that we need out there,” said Atul Grover, the AAMC’s chief advocacy officer.

Ten years to even make a dent in the shortage of doctors. A decade. Democrats have responded to a health cost crisis by creating a health care crisis. Now we’re not facing a shortage of health insurance but of actual doctors. Democrats actually succeeded in making the situation worse. Heckuva job.
