It would have been immensely helpful to have known this at the time the health care debate was going on:
In selling the health care overhaul to Congress, the Obama administration cited a once obscure research group at Dartmouth College to claim that it could not only cut billions in wasteful health care spending but make people healthier by doing so.
Wasteful spending — perhaps $700 billion a year — “does nothing to improve patient health but subjects you and me to tests and procedures that aren’t necessary and are potentially harmful,” the president’s budget director, Peter Orszag, wrote in a blog post characteristic of the administration’s argument.
Mr. Orszag even displayed maps produced by Dartmouth researchers that appeared to show where the waste in the system could be found. Beige meant hospitals and regions that offered good, efficient care; chocolate meant bad and inefficient.
[. . .]
But while the research compiled in the Dartmouth Atlas of Health Care has been widely interpreted as showing the country’s best and worst care, the Dartmouth researchers themselves acknowledged in interviews that in fact it mainly shows the varying costs of care in the government’s Medicare program. Measures of the quality of care are not part of the formula.
For all anyone knows, patients could be dying in far greater numbers in hospitals in the beige regions than hospitals in the brown ones, and Dartmouth’s maps would not pick up that difference. As any shopper knows, cheaper does not always mean better.
Unfortunately, when it came to information-gathering, the political system decided to go the Nancy Pelosi route.
