America's Doctors Are Performing Expensive Procedures That Don't Work (vox.com)
"The proportion of medical procedures unsupported by evidence may be nearly half," writes a professor of public policy at Brown University. An anonymous reader quotes his article in Vox:
The recent news that stents inserted in patients with heart disease to keep arteries open work no better than a placebo ought to be shocking. 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.
The stent controversy serves as a reminder that the United States struggles when it comes to winnowing evidence-based treatments from the ineffective chaff. 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"... Estimates vary about what fraction of the treatments provided to patients is supported by adequate evidence, but some reviews place the figure at under half.

The medical literature clearly indicates that the US is one of the few western countries remaining that routinely extracts nearly all asymptomatic wisdom teeth.
There is no medical reason why this is necessary unless the teeth are severely impacted or arranged in such a way that it is difficult to brush them.
Yet wisdom teeth extraction is a huge multibillion dollar industry for the dentistry practice in the US.
Somebody didn't RTFA! The study was looking specifically at stents used in cases of stable angina that is responsive to medication, and found that the stents were higher risk but provided no benefit over medication in the case of stable angina. The study did not attempt to address the effectiveness of stents in other cases including cases where medication did not control stable angina.
That still represents a lot of excessive costs for no benefit.
