This summer, Amazon purchased the One Medical national chain of primary care practices for nearly $4 billion. As David Blumenthal and Lovisa Gustafsson recently wrote in the Harvard Business Review , the success of the online retail giant's health care venture is hardly assured. One doesn't need to be a practicing family physician with health policy expertise to know that U.S. primary care is chronically overworked and underfunded, and as a result, medical student interest in primary care specialties has been anemic for the past two decades . As I discussed in a previous Medscape commentary , international primary care comparisons are less than flattering. The "fundamental question," asserted Blumenthal and Gustafsson, is: "Can profit-driven entrepreneurship and bottom-up innovation make the U.S. health care system work anywhere nearly as well as those in places like France, Sweden, Norway, Australia, the Netherlands, New Zealand, Germany, and Switzerland?"
