MEDS Score

Used in ED adults with suspected sepsis to rapidly stratify 28‑day mortality risk and guide early intensity of care. Provides independent prognostic value, with higher scores predicting severe sepsis, septic shock, and death (e.g., independent predictor of 28‑day mortality in ED cohorts 1 [Level II evidence]; 2 [Level II evidence]). Helps identify patients needing urgent antibiotics, aggressive resuscitation, and ICU evaluation.

In ED sepsis, predicts short‑term mortality but performance varies. Independent predictor of 28‑day mortality in septic patients 1 [Level II evidence] and associated with poor outcomes in early sepsis 2 [Level II evidence]. Limited by small derivation datasets, variable external validation, and omission of key physiologic parameters. Not reliable as a standalone decision tool; must be paired with clinical judgment and serial reassessment.
