“ Investigating staggering differences in how much Medicare spends on patients in various parts of the country, the Dartmouth team has discovered that in Manhattan and Miami, chronically ill Medicare patients receive far more aggressive care than very similar patients in places like Salt Lake City, Utah, and Rochester, Minn. Their research reveals that Medicare beneficiaries in high-cost states are likely to spend twice as many days in the hospital as patients in low-cost states and are far more likely to die in an intensive care unit. The
odds are higher that patients in high-spending regions will see 10 or more specialists during their final six months of life.
These facts alone aren't terribly surprising. But here's the stunner: Chronically ill patients who receive the most intensive, aggressive, and expensive treatments fare no better than those who receive more conservative care. In fact, their outcomes are often worse.
In high-cost regions, "patients with the same disease have higher mortality rates, very likely because of medical errors associated with increased use of acute-care hospitals," Wennberg and colleagues noted in a 2006 study of patients suffering from chronic diseases like cancer or congestive heart failure. As Fisher puts it, "Hospitals can be dangerous places—especially if you don't need to be there."
