Are there too many doctors?

This is a pretty interesting question. It depends who you ask ..."Take a look at the evidence, and it’s clear that the conventional wisdom is wrong. As I’ve discussed in the past, in areas of the country that boast more specialists, patient outcomes are worse—even after adjusting for differences in age, race and the overall health of the population. (I have written about this for both Health Beat and Dartmouth) A greater supply of primary care physicians, on the other hand, leads to better outcomes. So, Goodman quite sensibly concludes: “If improving the health and well-being of the population remains our goal we need more generalists and fewer specialists, today and in the future.”
