Diagnostic Error as Major Issue in Healthcare reported in ECRI and ASHRM Today

Great Bimal. 

The variations in presentation are so important. Just think of sensory nerve ending density from patient to patient, anatomical variations, lean vs obese, where the stone is in the bile duct system, and diferences from men and women (e.g. myocardial pain), and there maybe even racial and ethnic differences that we know little about, etc., etc. 

This against the background of the insensitivity of our diagnostic tests, it is a wonder we do so well! 

And my pet peeve, the results from the use of a stethoscope in people with different levels of experience and hearing abilities. After all the years of using a stethoscope we have no idea how accurate it is in different sub-groups of HCP's. 

So we not only have to factor in the variations in presentation, but also the variations in the sub-groups of HCPs that are doing the diagnosis! 

Can women as a whole hear heart sounds better than men? Do we even know that?

In our research don't we need to know the basics in parallel with any computer or other help in diagnosis that we work upon?

> 1. A major reason for failure to broaden differential diagnosis may be our lack of awareness of the wide variation in clinical presentations of a given disease ranging from highly typical to highly atypical in different patients. This may be due to medical school and textbook teaching which focuses primarily on typical presentations of a disease. Awareness of variation could be increased, I suggest, by looking at summaries of presentations in about one hundred consecutive patients with a given disease seen at a large medical institution. These summaries could be stored in a computer file which could be made available to all interested physicians.

I believe, a presentation should be looked upon as a clue to a disease and not pretest evidence which should be ruled in or out by further testing. This would avoid premature closure.

I believe it is all right to break this rule by suspecting a rare disease if all other suspected diseases are found not to be present.

I would like to thank John Ely and other investigators who have started to look at diagnosis in actual practice and increase our understanding of this important process.

Besides using Dr. Croskerry's articles and information from the Foundation for Critical Thinking, I am also using the textbook Patient Safety in Emergency Medicine by Croskerry and Emergency Medicine Decision Making by Weingart as references.  In addition I have been following the work of Dr. Kevin deLaplante of the Critical Thinker Academy.
