User Manual

Dietitian App User Manual

Dietitian App is a clinical support tool for dietitians and health professionals. It brings together patient management, nutrient analysis, client food diary collection, growth tracking, anthropometry, nutrient requirement calculators, diabetes tools, formulary access, and biochemistry reference information.

Clinical use statement

Dietitian App supports professional decision-making. It does not replace clinical judgement, local policy, primary source verification, diagnosis, individualised assessment, or professional responsibility.

Getting started

1. Create or select a patient

Start with the Patients area when you need to save information against a patient or client record.

2. Choose the clinical tool

Use the top navigation or dashboard cards to open Diet History, Growth Tracking, Anthropometry, Calculators, Formulary, Biochemistry, Diabetes, or Client Food Diary.

3. Review and verify outputs

Use app outputs as clinical support. Check results against the patient context, source data, local guidance, and professional judgement.

Saving, retrieving, and deleting records

Where saving is available, records are linked to the signed-in user and the patient or client identifier. Use a consistent patient/client ID to make future retrieval easier.

Saved diet histories and growth records should be reviewed before reuse, especially if patient details, age, weight, height, pregnancy status, lactation status, or clinical condition have changed.

Before deleting saved information, check that the record is no longer required. Deleted records may not be recoverable.

Accuracy and limitations

Calculators, growth outputs, nutrient comparisons, food composition results, formulary details, and reference ranges are intended to support clinical review. They should not be used as the only basis for clinical decision-making.

Food composition values may vary depending on the selected food, brand, preparation method, fortification, recipe, portion accuracy, and database completeness. Product details may change over time and should be checked against manufacturer information where relevant.

Biochemistry values must be interpreted using the reporting laboratory reference range and the full clinical context. Growth and anthropometry outputs should be interpreted alongside measurement quality, growth trajectory, diagnosis, treatment plan, and clinical judgement.

Support, references, and sources
