MUST

STEP 1

Body measurements

Use a reliable current weight and measured or documented height.

Height

Height (cm)

Accepted input range: 100–250 cm.

Use an alternative height measurement

STEP 2

Unplanned weight loss

Use the patient's usual weight from 3–6 months ago. Missing history must not be recorded as zero.

ADDITIONAL ASSESSMENT

Subjective screening

Review these findings when weight is estimated. Complete the measurements and questions below. Estimated measurements produce an approximate numerical score in this hospital version.

Mid upper arm circumference (cm)

Accepted input range: 10–60 cm.

Enter MUAC to see its interpretation.

Acute illness with no nutritional intake for more than 5 days (or likely) requires the high-risk pathway. Review this finding before confirming the category.

STEP 3

Acute disease effect

Score 2 only when both conditions apply: acute illness AND no nutritional intake for more than 5 days, or this is likely.

Reduced appetite alone does not meet the “no nutritional intake” condition.
