EHMRG Score — Emergency Heart Failure Mortality Risk Grade

The Emergency Heart Failure Mortality Risk Grade (EHMRG) is a validated 7-day mortality prediction score developed from a large Ontario, Canada administrative healthcare database of > 12,000 emergency department acute decompensated heart failure (ADHF) presentations. EHMRG uses 11 readily available clinical and laboratory variables to generate a risk level (very low to high) associated with 7-day mortality probabilities, enabling evidence-based disposition decisions: safe discharge from ED with aggressive outpatient follow-up (very low risk) vs. hospital admission vs. ICU admission (high risk). A prospective implementation study (EHMRG30-ST) confirmed its discriminatory power.
