The Malnutrition Universal Screening Tool (MUST) is a (validated) diagnostic screening tool for determining the extent of a patient’s malnutrition.
For this screening tool, every patient’s Body Mass Index (BMI) and
weight loss percentage is calculated, after which the patient is assigned a disease factor. The MUST helps to recognize and treat malnutrition at an early stage.
(Source: Guidelines for Screening and Treating Malnutrition.)
Purpose
The MUST score is used to determine the extent of malnutrition or the risk of malnutrition. To treat malnutrition quickly and effectively, it is important to identify the malnutrition at an early stage.
Patient Population
The MUST is used for patients aged 18 and older.
For children, the STRONGkids tool is used.

MUSTScore
Root concept of the MUSTScore information model. This root concept contains all data elements of the MUSTScore information model.
A person’s Body Mass Index (BMI), also known as their Quetelet index (QI), is an index indicating the ratio between a person’s height and weight. This BMI is expressed in kg/m2.
Illness can result in reduced food intake, leading to a higher risk of malnutrition.
The IllnessScore concept is used to indicate that the patient is seriously ill and that the patient has not eaten for more than 5 days or that there is a chance that the patient has not eaten for more than 5 days.
Technical specifications in HL7v3 CDA and HL7 FHIR
To exchange information based on health and care information models, additional, more technical specifications are required.
Not every environment can handle the same technical specifications. For this reason, there are several types of technical specifications:
HL7® version 3 CDA compatible specifications, available through the Nictiz ART-DECOR® environment
HL7® FHIR® compatible specifications, available through the Nictiz environment on the Simplifier FHIR
