nutric_score: Nutrition Risk in the Critically Ill (NUTRIC) Score

Description

Calculates the **NUTRIC Score** to assess the risk of adverse outcomes from under-nutrition in critically ill adult patients. The score integrates patient characteristics (age, BMI), baseline health status (comorbidities, SOFA score), and anticipated length of stay. The maximum score is 5 points for the standard NUTRIC score.

Usage

nutric_score(age, bmi, sofa_score, comorbidities_count, days_on_icu_ge_2,
             il6_level_pg_ml = NA)

Value

A list containing:

NUTRIC_Score

The calculated risk score (Range 0-5).

Risk_Classification

Classification (Low Risk \(\le\) 4, High Risk \(\ge\) 5).

Nutrition_Recommendation

Guidance on the intensity of nutrition support.

Arguments

age

Numeric. Patient age in years. (50-74 years adds 1 point, \(\ge\)75 years adds 1 point).

bmi

Numeric. Body Mass Index in kg/m^2. (BMI < 20 or \(\ge\) 35 adds 1 point).

sofa_score

Numeric. Sequential Organ Failure Assessment (SOFA) score on admission. (SOFA 5-9 adds 1 point, SOFA \(\ge\) 10 adds 1 point).

comorbidities_count

Numeric. Count of comorbidities (e.g., Cancer, CKD, Liver disease, CHF). (\(\ge\) 2 adds 1 point).

days_on_icu_ge_2

Numeric (0 or 1). Anticipated length of stay in the ICU of 2 days or more. (1 = Yes, +1 point).

il6_level_pg_ml

Numeric (Optional). Interleukin-6 (IL-6) level in pg/mL. Used in the modified NUTRIC (mNUTRIC) score. (\(\ge\) 1000 pg/mL adds 1 point if applicable to the highest category).

# Example 1: Low Risk
# 40yo (0), BMI 25 (0), SOFA 2 (0), 1 comorbidity (0), <2 ICU days (0)

# Example 2: High Risk
# 70yo (+1), BMI 35 (+1), SOFA 12 (+1), 2 comorbidities (+1), >=2 ICU days (+1)
# Score = 5
