Dietetics: The Numbers That Drive Follow-Up

Nutritional monitoring is all about consistency

A one-off dietetic consultation is useful for establishing a diagnosis and providing guidance. What truly shifts a patient's trajectory is the series: returning, measuring again, adjusting. This has a practical implication: the value of a dietetic record lies less in the depth of the first consultation than in the regularity of measurements taken thereafter.

Malnutrition in older adults, overweight and metabolic syndrome, diabetes, eating disorders: the presenting concerns differ, but the method stays the same — figures, collected the same way, compared over time.

The measurements that structure the record

• Weight, height, BMI, the latter derived from the first two;
• usual or reference weight, and percentage weight loss: it is this figure, not the absolute weight, that triggers a malnutrition alert;
• waist circumference, for cardiometabolic risk;
• calf circumference and grip strength, two straightforward markers of muscle mass and function;
• estimated intake, both energy and protein, along with the dietary assessment method used — 24-hour recall, food diary, food frequency questionnaire;
• number of meals and level of physical activity.

Two laboratory values frequently round out the picture: HbA1c and serum albumin. These are not measured by the dietitian — they are carried over from tests ordered by the physician, and the record should make this clear to avoid any ambiguity about their source.

Screening tools

Three short questionnaires are genuinely useful and should be recorded like any other result, with their date:

• MNA-SF, nutritional screening for older adults: a low score flags malnutrition or risk thereof;
• SEFI, simplified food intake evaluation: helpful when a patient struggles to describe what they eat;
• SCOFF, eating disorder screening: two positive responses warrant further investigation.

As with any assessment tool, what goes into the record is the score and the date it was administered — not the questionnaire itself.

The chart as a consultation tool

Weight is the measurement patients focus on most — and often the most discouraging one: three weeks without change can be enough to make someone give up. A chart that shows, alongside weight, a falling waist circumference or a rising protein intake puts progress in its proper perspective.

The direction of change also differs depending on the measurement: weight loss is a positive sign in an overweight patient, but a warning sign in a malnourished older adult. Useful monitoring accounts for this direction rather than treating every downward trend as progress.

Three situations, three approaches to monitoring

The malnourished older adult. Here, falling weight is the red flag, and the percentage of weight lost carries more weight than the absolute figure. The MNA-SF sets the framework, calf circumference and grip strength reflect muscle status, and estimated protein intake guides the care plan. Follow-up intervals are short: a matter of weeks, not months.

Overweight and metabolic syndrome. Weight remains the figure patients expect to see, but waist circumference and reported HbA1c are better indicators of risk. Monitoring is a long-term commitment, and the main challenge is sustaining motivation: charts serve as much to keep patients engaged as to fine-tune the dietary plan.

Eating disorders. The SCOFF opens a door — it does not make a diagnosis. Weighing itself can become counter-therapeutic, and the work is carried out in close collaboration with a physician and a psychologist. What the record holds here is primarily habits, context, and the decisions made about next steps.

What dietetics does not require

Unlike most allied health professions, dietetic consultations do not require a referral or prescription. That said, the record still includes a field for the referring clinician when one is involved — a diabetologist, bariatric surgeon, or general practitioner — because they are owed the feedback.

In practice

The allied health module in Hakim-DZ provides dietetics with its own dedicated sections, organised by theme — anthropometry, intake and habits, reported laboratory values, clinical context, and screening — along with the three questionnaires MNA-SF, SEFI, and SCOFF, and individual charts for each numerical measurement, each reflecting the relevant direction of change.
