For experienced clinicians, there are tons of quick reference sections to act as a secondary brain. • 70+ common chief complaints • Differential diagnoses, relevant history and physical exam, initial tests, initial treatments, and pearls for each chief complaint • No fluff like in other resources; focused ED-relevant info only • 75+ top EM clinical decision tools / calculators and how to interpret the results • No email address / login required to use This app is explicitly designed for healthcare professionals only, not the lay public.
