Emergency Medicine Calculators — Clinical Medicine

Validated emergency scoring: Glasgow Coma Scale, APACHE II, CURB-65, ABCD2, injury severity, and burn surface area percentage. These are decision aids with published criteria; they support clinical judgement in trained hands rather than replacing it.
