This is Part 1 of EM Cases’ series on Diagnostic Decision Making with Walter Himmel, Chris Hicks and David Dushenski discussing the intersection of evidence-based medicine, cognitive bias and systems issues to effect our diagnostic decision making in Emergency Medicine. In this episode we first discuss 5 strategies to help you master evidence-based diagnostic decision making to minimize diagnostic error, avoid over-testing and improve patient care including:
1. The incorporation of patients’ values and clinical expertise into evidence-based decisions
2. Critically appraising diagnostic studies
3. Understanding that diagnostic tests are not perfect
4. Using the concept of test threshold to guide work-ups
5. Understanding that the predictive value of a test depends on the prevalence of disease
We then go on to review some of the factors that play into the clinician’s and patient’s risk tolerance in a given clinical encounter, how this plays into shared decision making and the need to adjust our risk tolerance in critical situations. Finally, we present some strategies to prevent over-testing while improving patient care, patient flow and ethical practice.

Best Case Ever 33: Over-correction of Hyponatremia
Rapid over-correction of Hyponatremia can have devastating consequences: for one, osmotic demyelination syndrome (ODS) can result in destruction of the pons and a locked-in state. We don't see ODS very much as it's onset is delayed and usually sets in after the patient is admitted to hospital (or worse, sent home). Nonetheless, we need to know how to manage Hyponatremia in the ED so that we prevent ODS from ever happening. In this Best Case Ever, Dr. Melanie Baimel describes the case of a young woman who came in to the ED after drinking alcohol and taking Ecstasy, wanted to leave AMA after her Hyponatremia had inadvertently been corrected too rapidly, and the conundrum that ensued.
In the upcoming episode, Dr. Baimel and the first ever Internal Medicine specialist on EM Cases, Dr. Ed Etchells, discuss a rational step-wise approach to managing Hyponatremia, tailored for the EM practitioner; when you might consider giving DDAVP in the ED, the best way to correct Hyponatremia, how to manage the patient who's Hyponatremia has been corrected too quickly, and an easy approach to the differential diagnosis. Get a sneak peak at the algorithm that will be explain and review in the upcoming episode......
