Introducing the M100 Assess: Smarter nutritional screening for hospital teams
Published on 01 Jun 2026
Hospitals routinely measure weight. But it’s an action that involves multiple manual steps, calculations, transcription, missed screening fields, and delayed identification of nutritional or metabolic risk.
Collectively, these individual steps create inconsistencies in records and slow down clinical responses.
Developed in partnership with The British Association for Parenteral and Enteral Nutrition (BAPEN), our M100 Assess nutritional assessment column scale is designed to close these gaps by turning routine weighing into a structured nutritional assessment workflow, with integrated Malnutrition Universal Screening Tool (MUST) and Waist-To-Height Ratio (WHtR) calculations.
More about MUST
MUST is a nationally recognised, NICE recommended screening tool developed to support the identification of malnutrition risk.
The most commonly used screening tool in the UK, MUST provides a simple, evidence-based framework aimed at supporting the early identification of nutritional risk and guiding appropriate care planning across healthcare and community settings
A cornerstone of BAPEN’s work, MUST plays a critical role in improving awareness of malnutrition risk and the value of screening in providing high-quality nutrition care and directly impacts:
· Recovery times
· Complication rates
· Length of hospital stay
· Overall healthcare costs
However, despite this, screening is often inconsistent in practice because it relies on many manual steps that extend beyond the weighing process.
The M100 Assess embeds MUST-related workflows into the act of weighing itself, reducing the need for separate calculations and documentation.
More about WHtR
WHtR is a practical measure of central adiposity that is used alongside BMI to improve obesity and cardiometabolic risk assessment.
Clinical guidance recognises that BMI alone is not always sufficient, particularly when identifying:
- Central obesity risk
- Weight-related health conditions
- Long-term metabolic risk trends
In practice, this means WHtR is often underused because it adds to overall workloads.
The M100 Assess workflow seamlessly integrates into routine measurements rather than treating it as an additional task
M100 Assess
The M100 Assess is designed to turn standard weighing into a complete nutritional assessment. 
Instead of there being separate steps - weight, then BMI, then MUST scoring - the process is streamlined into a single workflow, helping reduce delays and errors and supporting:
- Weight measurement
- MUST screening support
- WHtR-related assessment capture
- Structured recording of key clinical data
Why this matters for hospitals
At an operational level, small inefficiencies can rapidly scale.
The benefits of integrating MUST and WHtR into routine weighing are widespread and include:
- Faster MUST calculation at the point of care
- More consistent screening across wards and users
- Improved alignment with NICE expectations for nutritional assessments
- Stronger documentation for audit and governance
- Better continuity of care during handovers and discharges
- Reduced variation in how screening is performed
With malnutrition reportedly contributing to an estimated £22.6billion in NHS costs a year, improving early identification is both a clinical and operational priority.
From routine measurement to value-driven outputs
Embedding screening into routine measurement makes compliance easier to achieve in practice, not just in policy.
The M100 Assess is specifically designed to modernise one of the most routine tasks in healthcare. By integrating MUST and WHtR into workflows and reducing reliance on manual calculations and transcriptions, hospitals can move from isolated measurements to structured clinical information.
The end result: Improved care quality and futureproofed operational efficiency without any added complexity.
