Medical errors are a real problem. I won't deny that.
It was bad enough when the often-quoted Institute of Medicine figure that 98,000 deaths per year in the U.S. are caused by medical errors was in vogue, but now a paper in the Journal of Patient Safety states that adverse medical events result in 210,000 to 400,000 deaths per year and 10 to 20 times those numbers of serious harms.
Since the paper disparages the medical profession, it has received a lot of media attention.
Most articles about it simply regurgitate the dismal estimates without any real attempt to dig into the paper's methods.
Let's take a closer look.
As is true of many papers, the abstract is a bit sketchy when describing how the paper arrived at its conclusion.
