This particular study looked at hospital-based deaths, of which there are around 715,000 per year, which would imply that these estimates, if accurate, would mean that medical errors cause between 35% and 56% of all in-hospital deaths, numbers that are highly implausible, something that would be obvious if anyone ever bothered to look at the appropriate denominators. For one thing, there are only 2.7 million total deaths per year in the US, which would mean that these estimates, if accurate, would translate into 9% to 15% of all deaths being due to medical errors.

When last I discussed this issue three years ago, specifically a rather poor study out of The Johns Hopkins that estimated that 250,000 to 400,000 deaths per year are due to medical errors, I pointed out how these figures are vastly inflated and don't even make any sense on the surface.

You'll see figures of 250,000 or even 400,000 deaths each year due to medical errors, which would indeed be the third leading cause of death after heart disease (635,000/year) and cancer (598,000/year). There is a myth promulgated by both quacks and academics who should know better that medical errors are the third leading cause of death in the United States.
