WorstFirst trains that instinct. Pick a chief complaint and work through a structured decision tree — the same worst-first reasoning used at the bedside — before settling on the benign explanation. WHAT'S INSIDE - 29 chief-complaint decision trees spanning cardiovascular, respiratory, neurologic, abdominal, trauma, tox, and more - Branch-by-branch reasoning with teaching pearls and common pitfalls - Citations to landmark literature and current guidelines throughout - Fully offline — no account, no sign-in, no data collection WHO IT'S FOR Medical students, EM residents, and other healthcare trainees building their approach to undifferentiated complaints.
