Abstract

Among patients admitted in the intensive care units (ICU) the prevalence of malnutrition is high, often associated with poor prognosis. Approximately two-thirds of critically ill patients do not meet the energy intake goals. In 2011, analyses of multicenter cohorts led to the development of the NUTrition Risk in the Critically ill (NUTRIC) score, the first malnutrition screening tool validated with data from critically ill patients. The NUTRIC score is calculated based on a variety of routinely used variables in the ICU setting, enabling the identification of patients who would benefit from aggressive medical nutrition therapy (MNT). Its modified version, the mNUTRIC, leaves out the assessment of interleukin-6 without compromising its prognostic ability. In the more recent version (NUTRIC-SF), it is combined with frailty and sarcopenia screening tools to reflect the novel malnutrition criteria. All scores emphasize on the provision of macronutrients, with increased scores being associated with 28-day mortality, increased ICU length of stay, and duration of mechanical ventilation support. Compared with other malnutrition screening tests, the NUTRIC scores have a higher prognostic value and a lower number needed to screen (NNS), being the only tools validated in the ICU setting.
