In "The 'Doc Fix'—Another Missed Opportunity," a New England Journal of Medicine Perspective, Stuart Guterman offers his thoughts on the continuing saga of Medicare's "sustainable growth rate" formula, or SGR, originally intended to limit the rate of growth in doctors' fees to growth in the overall economy. Guterman, The Commonwealth Fund's Vice President for Medicare and Cost Control, says that despite the failure of Congress's most recent attempt to repeal the SGR, there is widespread agreement that it must go, as well as growing realization that the current fee-for-service payment system must be replaced.
