Nutrition Risk in the Critically Ill (NUTRIC) Score Calculator

The Nutrition Risk in the Critically Ill (NUTRIC) Score is recommended by the American College of Gastroenterology (ACG) guidelines for nutrition therapy and can be safely used to identify critically ill patients at risk of malnutrition and 28-day mortality.

Compared to the other nutritional risk scores, such as the NRS-2002, NUTRIC was found to have a greater predictive power in screening intensive care unit patients who could benefit from nutrition therapy.

NUTRIC Score	Risk	28-day mortality (appx)
0	Low risk	1%
1		2%
2		3%
3		8%
4		11%
5		20%
6	High risk	30%
7		45%
8		58%
9		70%
10		80%

NUTRIC Score Explained

The nutrition Risk in the Critically Ill (NUTRIC) Score is recommended by the American College of Gastroenterology (ACG) guidelines for nutrition therapy and can be safely used to identify critically ill patients at risk of malnutrition and 28-day mortality.

The score consists in six items, and accounts for patient age, number of comorbidities, how long the patient has been admitted to ICU, their APACHE II and SOFA scores on presentation and their level of Interleukin 6 (which, if unknown, may be excluded from the score).

NUTRIC Score items	Answer choices	Pts
Age	<50	0
	50 - 74	1
	≥75	2
APACHE II Score	<15	0
	15 - 19	1
	20 - 27	2
	≥28	3
SOFA Score on presentation	<6	0
	6 - 9	1
	≥10	2
Number of comorbidities	0 - 1	0
Number of comorbidities	≥2	1
Days in hospital to ICU admission	0	0
Days in hospital to ICU admission	≥1	1
IL-6, µ/mL	0 – 399	0
IL-6, µ/mL	≥400	1

NUTRIC scores range from 0 to 10, where the higher the score, the greater the malnutrition and mortality risk:

NUTRIC Score	Risk	28-day mortality (appx)
0	Low risk	1%
1		2%
2		3%
3		8%
4		11%
5		20%
6	High risk	30%
7		45%
8		58%
9		70%
10		80%

Heyland et al. performed an observational study of 597 ICU patients expected to be admitted for more than 24 hours. Several clinical data was collected, that included, aside from the six items of the score, Body Mass Index (where <20), estimated % oral intake in the week prior, weight loss in the last 3 months, procalcitonin (PCT), and C-reactive protein (CRP) levels.

The six final items were drawn based on the statistical significance in the multivariable model and can be used in the scoring algorithm to identify ICU patients that are most likely to benefit from aggressive nutrition therapy.
