It’s important for critically ill patients to have a nutritional screening, assessment and monitoring as a part of full clinical assessment in critically ill patients to decrease mortality, morbidity and hospital costs. Nutritional screening should be done in the first day of admission or as soon as possible when the critically ill patients became haemodynamic stable. Most of nutrition screening tools before mNUTRIC score were not suitable for critically ill patients because malnutrition in ICU linked with inflammation and hypermetabolic state and the previous tools didn’t include these important two main cause for the pathology of malnutrition. So mNUTRIC score is considered the first validated specific nutrional screening in critically ill patients.
It’s validity was proved by many study, also mNUTRIC score proved by many studies to be correlated well with the clinical outcome of the critically ill patients. Many studies suggest to use nutritional risk screening (mNUTRIC) score for screening and subjective global assessment for nutritional assessment and to complement with other parameters available in each critical care setting such as laboratory markers and others to improve the quality for rapid diagnosis of malnutrition because only 3% only of ICU admission receive proper diagnosis of malnutrition, but the actual prevalence of ICU malnutrition is about 40% as reported by united state of health and human services.
This meta-analysis suggest that high mNUTRIC score critically ill patients correlated with increased 28-days mortality length of ICU stay and the study succeeded to prove patient with high mNUTRIC have greater risk of adverse event that for further researches to prove that patients with high mNUTRIC will benefit from aggressive nutritional intervention than those with low mNUTRIC. Patients with low mNUTRIC score no need to enter to further nutrition work up.
