Nutritional risk assessment at admission can predict subsequent muscle loss in critically ill patients


Muscle loss in critically ill patients may be related to nutrition. We study the association between modified NUTrition RIsk in the Critically ill (mNUTRIC) score obtained at admission to intensive care unit (ICU) and subsequent muscle loss. We measured rectus femoris cross-sectional area (RFCSA) by ultrasound on days 1, 3, 7, and 10 of ICU admission. We used linear mixed effects model following natural logarithmic transformation of the data. Forty-eight patients (median (IQR) age 66 (55–72.5) years, 71% male, APACHE II score 31 (25–34), BMI 24.2 (21.5–27.1) kg/m2) were analyzed. The high mNUTRIC score (>5) cohort (n = 35) lost significantly more muscle as compared to the low (≤5) group (n = 13); the adjusted ratio (high versus low group) of the geometric mean RFCSA were (0.58, 95% CI 0.46–0.75) for right and (0.61, 95% CI 0.49–0.77) for left, both p < 0.001. mNUTRIC score obtained at admission to ICU can identify patients at risk of subsequent muscle loss.
