Critical Illness Nutrition Risk Score (mNUTRIC) — free guideline decision tool
This tool computes the modified NUTRIC (mNUTRIC) score to assess nutrition risk in ICU patients, where ≥ 5 identifies high risk.
Open guideline tool →Guideline-based
Implements the decision logic from published clinical guidelines.

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).

Common questions
What is 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.
How is Critical Illness Nutrition Risk Score (mNUTRIC) calculated? What is the core formula?
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.
When is Critical Illness Nutrition Risk Score (mNUTRIC) used?
Use to stratify critical-illness nutrition risk and identify patients who benefit most from early aggressive nutrition support.
What are the key clinical points for Critical Illness Nutrition Risk Score (mNUTRIC)?
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.
What are the limits and cautions when using Critical Illness Nutrition Risk Score (mNUTRIC)?
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.
How is Critical Illness Nutrition Risk Score (mNUTRIC) calculated in practice? Can you show a worked example?
