Original publication

Saltzman JR, Tabak YP, Hyett BH, Sun X, Travis AC, Johannes RS. A simple risk score accurately predicts in-hospital mortality, length of stay, and cost in acute upper GI bleeding. Derived and validated in ~30 000 admissions; in-hospital mortality rose from ~0.3% at a score of 0 to ~25% at 5.

Guideline

AIMS65 uses only routinely available data and performs comparably to the Rockall score for mortality; the Glasgow-Blatchford score better identifies very-low-risk patients suitable for outpatient management and better predicts need for intervention. Use AIMS65 as a mortality-oriented triage aid alongside clinical judgement and endoscopic findings.
