🥩 Critical Illness Nutrition Risk Score (mNUTRIC)
This tool computes the modified NUTRIC (mNUTRIC) score to assess nutrition risk in ICU patients, where ≥ 5 identifies high risk.
Clinical takeaway
mNUTRIC drops IL-6 from the original score, making it usable where IL-6 is unavailable while preserving risk stratification. (original synthesis · not guideline verbatim)

When to use
Use to stratify critical-illness nutrition risk and identify patients who benefit most from early aggressive nutrition support.
How it works
Sum age, APACHE II, SOFA, comorbidity count, and pre-ICU stay (0–9). 0–4 low risk; 5–9 high risk → early aggressive nutrition with monitoring.
Key points
- mNUTRIC drops IL-6 from the original score, making it usable where IL-6 is unavailable while preserving risk stratification. (original synthesis · not guideline verbatim)
- It suits mechanically ventilated patients in whom dietary and weight history cannot be obtained.
- High-risk patients gain more from early enteral nutrition and progressive target achievement.

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.
| Age | < 50 yr (0) |
|---|---|
| APACHE II score | < 15 (0) |
| SOFA score | < 6 (0) |
| Number of comorbidities | 0–1 (0) |
| Days from admission to ICU | < 1 day (0) |
→mNUTRIC0 points
- Grade：0 points (0–9) → low nutrition risk (0–4)
- Management direction：Low risk: routine nutrition management, advance per ICU nutrition guidelines
- Note：mNUTRIC is the 9-point version with IL-6 removed (the original NUTRIC with IL-6 is 10 points). It integrates age, disease severity (APACHE II/SOFA), comorbidities, and acute starvation (length of hospital stay before ICU). Suitable for mechanically ventilated patients in whom dietary/weight history cannot be obtained
| Age | ≥ 75 yr (2) |
|---|---|
| APACHE II score | ≥ 28 (3) |
| SOFA score | ≥ 10 (2) |
| Number of comorbidities | ≥ 2 (1) |
| Days from admission to ICU | ≥ 1 day (1) |
→mNUTRIC9 points
- Grade：9 points (0–9) → high nutrition risk (5–9)
- Management direction：High risk: greater benefit from early, aggressive nutrition support (early enteral nutrition, progressive achievement of protein/calorie targets), close nutritional monitoring
- Note：mNUTRIC is the 9-point version with IL-6 removed (the original NUTRIC with IL-6 is 10 points). It integrates age, disease severity (APACHE II/SOFA), comorbidities, and acute starvation (length of hospital stay before ICU).
