More on premature closure and mystery novels

Our favorite whistle-blower points out that sooner or later one must end the diagnostic journey.  I tried to make this point: make a tentative diagnosis and then determine if the data fit that diagnosis. My point is that we should pay attention to the natural history of disease and the patient’s course over time.  Often we make logical diagnoses on day 1 but must rethink the diagnosis on day 3.

My main point is that we should be ready to re-open our diagnostic consideration when given new clues.  I call this the Columbo phenomenon.  When the data do not fit the diagnosis, restart your thinking engine.

But whistle-blower’s point is well taken.  I know about 20 causes of hypercalcemia, but I do not test for all of them in every patient.  Often when you hear hoof-beats it is a horse.  The key is that we must attend to the clues that there is no horse and a zebra is on the loose.

I still see major mistakes made when we ignore major clues that the high probability diagnosis is not the patient’s diagnosis.  How we balance premature closure with inability to close represents one component of the art of medicine.
