This BMJ article highlights the rather shocking statistic that medical errors are the #3 cause of preventable deaths in the US today.  What fraction of these are related to diagnostic error?

The only estimate that has ever been made is the back-of-the-envelope calculation by Lucian Leape, Don Berwick and David Bates that diagnostic errors could account for 40,000 - 80,000 deaths annually in the US. (see page 2405 of the file attached).  Their estimate was based on the finding that 10-20% of autopsies reveal major discrepancies, and their estimate that roughly have of these  might have\could have changed the patient's outcome.  There are approximately 2.5M deaths per year in the US.  They must have applied some additional adjustment to arrive at their final estimate of 40,000 - 80,000 deaths/year from diagnostic error; unadjusted the figures would be much higher.  Their estimate has not been disputed by anyone to my knowledge.

40,000 - 80,000 deaths/year would make diagnostic error one of the top 10 causes of death in the US annually, ahead of HIV (7,000 deaths), breast cancer (41,000 deaths) and in the neighborhood of diabetes-related deaths (78,000).  

Clearly we need better data to support these estimates, and hopefully someday research funding that would be in proportion to the harm associated with\ diagnostic error.
