According to Kaiser Health News the Institute of Medicine (IOM) recently released a report that contradicts the long-standing claims of the Dartmouth Health Atlas that variations in Medicare spending are attributable mostly to the greed of doctors.
The context of the report was to inform policymakers on the wisdom (or lack thereof) of proposals to pay providers more in low-cost areas and pay less in high-cost areas. The $8.5 million report found that local variations in Medicare spending do not correlate with variations in non-Medicare spending.
This finding is unsurprising. In fact, NCPA Scholars Andrew Rettenmaier and Thomas Savings came to precisely the same conclusion in a report published four years ago (surely for a whole lot less money).
