Why American doctors keep doing expensive procedures that don’t work

Each year, hundreds of thousands of American patients receive stents for the relief of chest pain, and the cost of the procedure ranges from $11,000 to $41,000 in US hospitals.

But in fact, American doctors routinely prescribe medical treatments that are not based on sound science.

As surgeon and health care researcher Atul Gawande observes, “Millions of people are receiving drugs that aren’t helping them, operations that aren’t going to make them better, and scans and tests that do nothing beneficial for them, and often cause harm.”
