The Malnutrition Universal Screening Tool (MUST) is a widely used adult nutrition screening framework that assigns points from three domains: BMI, unplanned weight loss, and acute disease with likely poor intake. The total score stratifies risk as low, medium, or high, helping trigger timely nutrition intervention.
Formula: MUST = BMI score (0-2) + weight-loss score (0-2) + acute disease effect score (0 or 2).
Higher MUST scores indicate greater likelihood of clinically meaningful malnutrition risk and need for nutrition-focused follow-up.
Use this tool at admission and periodic review in adult care settings to standardize malnutrition risk screening.
MUST is a screening instrument and does not replace full nutrition assessment, etiologic diagnosis, or individualized intervention planning.
