Can free medical school help fix the American health care system? In this weekend’s opinion section, two physicians, Dr. Peter B. Bach and Dr. Robert Kocher, propose that it can.

Huge medical school debts — doctors now graduate owing more than $155,000 on average, and 86 percent have some debt — are why so many doctors shun primary care in favor of highly paid specialties, where there are incentives to give expensive treatments and order expensive tests, an important driver of rising health care costs.

Fixing our health care system will be impossible without a larger pool of competent primary care doctors who can make sure specialists work together in the treatment of their patients — not in isolation, as they often do today — and keep track of patients as they move among settings like private residences, hospitals and nursing homes. Moreover, our population is growing and aging; the American Academy of Family Physicians has estimated a shortfall of 40,000 primary care doctors by 2020. Given the years it takes to train a doctor, we need to start now.

Making medical school free would relieve doctors of the burden of student debt and gradually shift the work force away from specialties and toward primary care. It would also attract college graduates who are discouraged from going to medical school by the costly tuition.
