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

Art, your comment on variation in presentations of skin diseases is very enlightening. Is it possible for you to put presentations of a particular disease say herpes simplex in different patients in a computer file that I and others can easily access. We could then perhaps learn to diagnose it like you do. I wish somebody would do for diseases like pulmonary embolism, myocardial infarction, pneumonia what you have done for skin diseases. Thank you for your great comment.

Bimal, This is a great comment on variation.  We too often focus on the "rare birds" instead of diagnostic error due to variants of common disease.  We teach medical students about pemphigus vulgaris (see a new patient with pemphigus about once every 10 years) but for example how often do we insure that primary care physicians understand the variations of herpes simplex.  Practicing in a rural community I had a patient treated with Keflex about 6 times over 3-4 years for grouped vesicles on the palm.  The PCP thought it was bacterial.  The PCP was likely trained to look for herpes on the lips and genitals, and did not see the pattern of the grouped vesicles because of the thickness of the stratum corneum of the palm, making it difficult to see the lesions as vesicles.    Also had probably been taught that herpes does not occur anywhere which it can.  In the same community months later I had a hospital consult for an OB patient with grouped vesicles on the thigh in the same community, obvious herpes simplex, but the hospitalist and attending could not diagnose it.   This is anecdotal, but I can tell you that all dermatologists worldwide are gritting their teeth about the crazy number of "bilateral cellulitis" consults for obvious stasis dermatitis, and host of other repeatable diagnostic mistakes of common presentations.

In our work we have been systematically collecting cases of disease presenting with skin, eye, oral mucosal, hair and nail findings for 15 years.  We have over 100,000 images that are systematically catalogued and obtained from leading institutions and experts.  If you look through an expansive set of images for a disease, you can easily see variants that are simply not in the text books.  For instance a fixed drug eruption presents most typically with a single or few round patches on the genitals or face or perhaps an extremity.  A known variant is bullous fixed drug eruption.  The cases we have systematically collected show many fixed drug eruptions localizing to the web spaces of the hand. Having had the  I had a patient with a lesion in the web spaces treated with lotrimin and other antifungals and it was fixed drug.  We teach to the classic and then we expect clinicians to generalize to the variants.  It seems to be a flawed premise.  From a cost perspective, my hunch is that the volume of error around variants of common dwarfs the missed rare birds.  Art

I did not have a chance to comment during John Ely's interesting webinar yesterday as I joined in by telephone. Here are my thoughts about his important study.

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.



2. An atypical presentation is often interpreted as low pretest evidence due to low pretest probability of a disease which may be ruled out without further testing. 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.



3. The rule of not neglecting base rate is a statistical rule which may not apply in a given, individual patient as we saw in the patient found to have neurosyphilis. 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.



4. There is so lttle we know about how diagnosis is performed in actual practice or should be performed to minimize diagnostic errors. 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.



All the best,

Bravo and hats off to you, Jeffery!  If critical thinking skills can be built into the community college program training paramedics in Bossier Parish, North Louisiana, never let it be said such training is ethereal, too difficult, or relevant only to the ivory tower.

I am developing a module on critical thinking for my paramedic program.  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.
