Malnutrition Universal Screening Tool (MUST)


The 'MUST' calculator is a five- step nationally recognised and validity screening tool for ‘ADULTS’ and can be used to establish nutritional risk using either objective measurements to obtain a score and a risk category or subjective criteria to estimate a risk category but not a score. The MUST tool is the most common form of nutritional screening used in the UK across hospitals as well as in the hospitals.

A full electronic step by step tool can used on the link below:
