Building a Clinical Nutrition Plan from Assessment Findings

Assessment generates a great deal of information: diet history, weight and waist, laboratory results, symptoms, medicines, the timeline and matrix. The challenge is to convert that information into a plan that is specific, prioritised, realistic and measurable. This article sets out a practical sequence for doing so and works through one case from start to finish.

Step 1: Summarise the findings

Begin with a brief summary organised under the familiar headings of anthropometric, biochemical, clinical and dietary findings, plus relevant context from the timeline and the patient’s circumstances. A summary on one page forces the practitioner to decide what matters.

Step 2: Write nutrition diagnoses

The nutrition care process used in dietetics expresses each nutrition problem as a statement with 3 parts: the problem, its cause and the evidence for it. This format, sometimes called a PES statement for problem, etiology and signs or symptoms, makes each problem precise and points directly to an intervention.

For example: “Excessive intake of refined carbohydrate and sugar sweetened drinks, related to irregular work hours and reliance on convenience food, as evidenced by a diet history showing 3 sugary drinks daily, raised triglycerides and HbA1c in the prediabetes range.”

Nutrition diagnoses differ from medical diagnoses. The medical diagnosis might be prediabetes; the nutrition diagnosis names what about the person’s eating contributes to it and why.

Step 3: Prioritise

Most patients have several nutrition problems. Prioritise those that are urgent or unsafe, such as malnutrition or a dangerous interaction, those with the greatest influence on the patient’s main concerns, and those the patient is most ready to address. 2 or 3 problems at a time are usually enough.

Step 4: Set goals with the patient

Goals work best when they are specific, measurable, achievable, relevant and time bound, and when the patient has helped choose them. “Replace sugary drinks with water or unsweetened tea on workdays within 2 weeks” is clearer than “eat better”. Distinguish behavioural goals, which the patient controls, from outcome goals such as weight or HbA1c, which follow from behaviour.

Step 5: Estimate energy and protein needs

Where energy targets are useful, predictive equations such as the Mifflin St Jeor equation estimate resting energy expenditure, which is then adjusted for activity. These estimates are approximations; weight change over time is the real test. Protein needs are calculated by body weight and adjusted for age, illness, activity and kidney function, using adjusted body weight in people with obesity where appropriate. Many plans for weight management use a moderate energy deficit, but for many patients a focus on food quality and structure is more useful than precise calorie targets.

Step 6: Translate targets into meals

A plan the patient cannot picture will not be followed. Translate targets into concrete meals and snacks built from foods the patient already eats, using tools such as a plate model, sample days and simple swaps. Consider who shops and cooks, budget, cultural and religious practices, work patterns and cooking skills.

Step 7: Plan monitoring

Decide in advance what will be measured and when: behaviours through food records or checklists; outcomes such as weight, waist, blood pressure, glucose readings or symptoms; and laboratory tests at appropriate intervals. Define what progress would look like.

Step 8: Document and share

A written plan helps the patient, and a concise summary helps colleagues. Share relevant parts with the patient’s doctor, particularly where dietary change may affect medicines, and with other practitioners involved.

A worked case

Summary of findings

Nutrition diagnoses

1. Excessive intake of refined carbohydrate and added sugar related to large rice portions, sweet tea and fried snacks on shift, as evidenced by diet history, raised HbA1c and triglycerides.
2. Inadequate protein intake at breakfast and during shifts related to meal pattern and limited options at work, as evidenced by diet history and hunger driving snacking.
3. Irregular meal timing related to night shifts, as evidenced by eating a large meal after returning home in the early morning and frequent night snacking.

Goals agreed

• Reduce sugar in tea by half in 2 weeks, then to none, and limit to 2 cups a day.
• Take a packed shift meal from home 5 nights a week, replacing fried snacks.
• Reduce rice to one moderate portion per meal, filling half the plate with vegetables and adding dal, sambar or curd.
• Walk for 10 minutes after his main meal.

Translating into meals

His wife joins the second consultation, and meal preparation is planned together. His doctor is informed and screens him for sleep apnoea, given his snoring.

Monitoring

• Weekly: a checklist of goals achieved; weight once a week.
• Monthly: waist circumference, home blood pressure readings.
• At 3 months: HbA1c, triglycerides, ALT.

Outcome

At 3 months, he has lost 4 kg and 5 cm from his waist, his triglycerides and ALT have improved and his HbA1c has fallen to 41 mmol/mol. He has been diagnosed with mild sleep apnoea, which is being treated. The next phase adds strength exercise and further adjustment of rice portions.

Why structure helps

A structured sequence prevents 2 common failures: plans that are too vague to act on, and plans that try to change everything at once. By naming precise problems, prioritising them, agreeing concrete goals and building meals from the patient’s own food, the practitioner produces a plan that the patient can follow and that can be measured.
