The Cost of Dying

Last year, Medicare paid $50 billion just for doctor and hospital bills during the last two months of patients' lives - that's more than the budget of the Department of Homeland Security or the Department of Education.

And it has been estimated that 20 to 30 percent of these medical expenditures may have had no meaningful impact. Most of the bills are paid for by the federal government with few or no questions asked.

One of her doctors, Ira Byock, told 60 Minutes correspondent Steve Kroft it costs up to $10,000 a day to maintain someone in the intensive care unit. Some patients remain here for weeks or even months; one has been in the ICU since May.

"This is the way so many Americans die. Something like 18 to 20 percent of Americans spend their last days in an ICU," Byock told Kroft. "And, you know, it's extremely expensive. It's uncomfortable. Many times they have to be sedated so that they don't reflexively pull out a tube, or sometimes their hands are restrained. This is not the way most people would want to spend their last days of life. And yet this has become almost the medical last rites for people as they die."

And once someone is admitted to the hospital, Fisher says, they're likely to be seen by a dozen or more specialists who will conduct all kinds of tests, whether they're absolutely essential or not.
