The reason: extrapolating from data from the Harvard Medical Practice Study,2,3 performed a decade earlier, the authors estimated that 44,000 to 98,000 Americans die each year from medical errors.* More shockingly, they translated these numbers into the now-famous “jumbo jet units,” pointing out that this death toll would be the equivalent of a jumbo jet crashing each and every day in the United States.
