Many other countries’ healthcare systems outperform ours for one simple reason: They place a much greater emphasis on primary care, which occupies the central place in their systems. “The evidence is that where you have more primary care physicians, where you coordinate care, and where you pay to keep people healthy, you get better outcomes at lower cost,” says David Nash, MD, founding dean of the College of Population Health, part of Thomas Jefferson University in Philadelphia.
The evidence that Nash mentions includes studies by Barbara Starfield and her colleagues at Johns Hopkins University. In a 2005 Health Affairs paper, they showed that a higher ratio of primary care physicians to the population is associated with a lower mortality rate from all causes and from heart disease and cancer; in contrast, having more specialists in a particular area does not decrease the overall mortality rate or deaths from cancer and heart disease.
