Example
- BMI
- 15 kg/m^2
- Unintentional weight loss over 3-6 months
- 5 %
- Days with little or no nutritional intake
- 2
Result: High risk of refeeding syndrome -- 1 major + 0 minor NICE criteria (high risk = >= 1 major or >= 2 minor).
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Major
- BMI < 16, weight loss > 15% in 3-6 mo, > 10 days little/no intake, or low pre-feeding K/Mg/PO4.
- Minor / risk
- BMI < 18.5, weight loss > 10%, > 5 days little/no intake, or alcohol/drug history. High risk = >= 1 major or >= 2 minor. Cross-links icu-nutrition-target.
