Definition of Diagnosis Error

Great conversation 
I often cannot make a diagnosis the first time I see a patient. In fact it may take many visits, testing, and cogitation to arrive at the diagnosis that fits all the facts and even then it may be wrong. 
Early on in this process I am often frustrated by the need to "code" a diagnosis. Early on I may not know the diagnosis but if forced to code on it may often be in error. I sometimes resort to just coding the most pertinent symptoms (but the business people do not like that). It would be much better if our coding systems would allow for coding "preliminary" or "working" or "presumed" and finally "confirmed." But alas we are not, we are not allowed a coding system that is clinically relevant but rather the owners of the system profit from a coding billing system. Until this changes we will be forced to use inadequate means to document (and hence an inadequate means to measure) diagnostic reasoning.

I heartily agree with the dynamic nature of the Dx process, and that explicitly including something akin to a "confidence interval" is not only appropriate, but would facilitate any physician's dilemma in having to make an either-or choice between a right and a wrong answer (e.g. one option would be to add a "confidence interval" field into the EMR, which could serve as a trigger/forcing strategy; I'm sure there are others).

I recall that Mark Graber openly invited feedback from the audience at the Sep 2015 conference (just after the IOM report was published) on these definitions, and he got a few suggestions in real time, but I don't know what happened thereafter.

Perhaps there is more, but in my mind, "incomplete" is a unique form of Dx error that is not necessarily captured by any of the other three.  One could argue that it's merely a form of missed Dx, but to lump it in to that category would lose a crucial nuance of the physician's cognitive process (e.g. it would tend to obscure an important cognitive bias at play in such cases).  There's much more than just this example, but for brevity sake, I'll end there.

>>> What is Diagnostic Error?
>>> 
>>> The Institute of Medicine recently defined diagnostic error as the failure to (a) establish an accurate and timely explanation of the patient’s health problem(s) or (b) communicate that explanation to the patient. Simply put, these are diagnoses that are missed altogether, wrong, or should have been made much earlier.

>>> These categories overlap, but examples help illustrate some differences:
>>> A missed diagnosis refers to a patient whose medical complaints are never explained. Many patients with chronic fatigue, or chronic pain fall into this category, as well as patients with more specific complaints that are never accurately diagnosed.
>>> 
>>> A wrong diagnosis occurs, for example, if a patient truly having a heart attack is told their pain is from acid indigestion. The original diagnosis is found to be incorrect because the true cause is discovered later.
>>> 
>>> A delayed diagnosis refers to a case where the diagnosis should have been made earlier. Delayed diagnosis of cancer is by far the leading entity in this category. A major problem in this regard is that there are very few good guidelines on making a timely diagnosis, and many illnesses aren’t suspected until symptoms persist, or worsen.
