Methodology · worked example, guidelines & full notes
Feeding is never delayed to correct electrolytes — potassium, phosphate, and magnesium are replaced concurrently. (original synthesis · not guideline verbatim)
When to use
Use to classify risk and set the starting calorie rate, thiamine supplementation, and electrolyte monitoring before and during refeeding.
How it works
High risk = ≥ 1 major (BMI < 16, loss > 15%, minimal intake > 10 days, low pre-feeding K/PO4/Mg) or ≥ 2 minor criteria. Extremely high = BMI < 14 or near-no intake > 15 days. Start 10 kcal/kg/d (extreme 5), thiamine first.
Key points
- Feeding is never delayed to correct electrolytes — potassium, phosphate, and magnesium are replaced concurrently. (original synthesis · not guideline verbatim)
- Thiamine is given before feeding and through the first 10 days to prevent Wernicke encephalopathy.
- Extremely high risk starts at just 5 kcal/kg/d with cardiac monitoring.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| BMI | 16–18.5 (minor) |
|---|---|
| Unintentional weight loss (3–6 months) | 10–15% (minor) |
| Intake/feeding status | Little or none > 5 days (minor) |
| Pre-feeding K/phosphate/magnesium | Normal (0) |
| Alcohol use history or relevant drugs (insulin/chemotherapy/antacids/diuretics) | None (0) |
→Refeeding riskHigh risk
- Determination:0 major criteria, 3 minor criteria → High risk (≥ 1 major or ≥ 2 minor = high risk)
- Feeding initiation:High risk: start at 10 kcal/kg/d, increase gradually to target over 4–7 days
- Vitamins:Supplement thiamine (vitamin B1) and a B-complex/multivitamin before feeding and for the first 10 days
| BMI | ≥ 18.5 (0) |
|---|---|
| Unintentional weight loss (3–6 months) | < 10% (0) |
| Intake/feeding status | Largely normal (0) |
| Pre-feeding K/phosphate/magnesium | Normal (0) |
| Alcohol use history or relevant drugs (insulin/chemotherapy/antacids/diuretics) | None (0) |
→Refeeding riskDoes not meet high-risk criteria (still assess individually)
- Determination:0 major criteria, 0 minor criteria → Does not meet high-risk criteria (still assess individually) (≥ 1 major or ≥ 2 minor = high risk)
- Feeding initiation:Advance per routine nutrition support, with attention to monitoring
- Vitamins:Supplement thiamine (vitamin B1) and a B-complex/multivitamin before feeding and for the first 10 days

FAQ
Frequently asked questions
- What are the limits and cautions when using Refeeding Syndrome Risk (NICE)?
- For licensed clinicians and clinical researchers. Interpret results with history, investigations and local protocols; not a diagnosis or prescription, and not a substitute for multidisciplinary decision-making or local guidelines.
- Does Refeeding Syndrome Risk (NICE) upload patient data? Where is it calculated?
- Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
- How is Refeeding Syndrome Risk (NICE) calculated in practice? Can you show a worked example?
