Use to triage upper GI bleeding — pair with Glasgow-Blatchford for discharge decisions.

A 5-point score (Albumin, INR, Mental status, Systolic BP, age 65) that predicts in-hospital mortality in acute upper gastrointestinal bleeding.

AIMS65 best predicts mortality and is simple to calculate; Glasgow-Blatchford better identifies low-risk patients suitable for outpatient management.

Mortality rises with each point — a score ≥ 2 is generally considered high risk and ≥ 3 carries markedly increased mortality.

At initial presentation with upper GI bleeding, using the first available labs and vital signs.
