Association between nutritional status, daily nutrition delivery and clinical outcomes of critically ill adult patients admitted to the intensive care unit: a protocol for Isfahan multicentre prospective observational cohort ICU study (the Isfahan-ICU study).

Introduction: There is currently limited information regarding the association between the modified Nutrition Risk in Critically Ill (mNUTRIC) score, nutrition delivery and clinical outcomes in critically ill patients admitted to the intensive care unit (ICU) section.

Methods And Analysis: The Isfahan-ICU study is a multicentre, prospective observational cohort study that will be conducted on critically ill adults treated in the trauma or medical ICU sections of six hospitals to investigate whether clinical outcomes, including length of ICU stay and 30-day survival, vary by the mNUTRIC score at admission or the 7-day nutrition delivery. This paper outlines the Isfahan-ICU study protocol approved by the ethics committee of Isfahan University of Medical Sciences, Iran.
