From the WSJ article “The Ultimate End-of-Life Plan: How one woman fought the medical establishment and avoided what most Americans fear: prolonged, plugged-in suffering”:
About a quarter of Medicare’s $550 billion annual budget pays for medical treatment in the last year of life. Almost a third of Medicare patients have surgery in their last year of life, and nearly one in five in their last month of life. In their last year of life, one-third to one-half of Medicare patients spend time in an intensive care unit, where 10 days of futile flailing can cost as much as $323,000. Medical overtreatment costs the U.S. health care system an estimated $158 billion to $226 billion a year.
