Description of intervention(s) / exposure
Enteral nutrition (EN) is the most preferred and common mode of nutrition provision in mechanically ventilated critically ill patients. Feeding formulas used for EN aim to provide complete nutrition in the form of both macro- and micronutrients. In Australia, the micronutrient composition of EN formulas is guided by standards established for a healthy population by the National Health and Medical Research Council (NHMRC). These standards, termed Nutrient Reference Values (NRVs), include the recommended dietary intake (RDI), adequate intake (AI) and upper level of intake (UL). Limited information is available on the micronutrient intake of critically ill patients receiving EN during routine clinical practice in the Intensive Care Unit (ICU). The aim of this retrospective observational study is to determine daily micronutrient intake of vitamins B12, D, C, A, iron, folate, thiamine, zinc, and selenium delivered from EN to critically ill adults admitted to Box Hill Hospital Intensive Care Unit (ICU), Melbourne, Australia between January 2018 and January 2020. Micronutrient intake will be assessed daily for the first seven days of ICU admission and compared to NRVs. There will be no participant involvement, only access to patient medical records.

Outcomes
Primary outcome [1] 324679 0
Composite outcome - Intake of vitamins B12, D, C, A, iron, folate, thiamine, zinc, and selenium delivered from enteral nutrition (EN) during routine clinical practice in critically ill adult patients expressed as a percentage of the recommended daily intake (RDI) (or adequate intake (AI) where RDI is not reported). Calculation will be completed using the information collected from the patient's electronic medical records.

Statistical methods / analysis
Data analysis will be descriptive, using mean and standard deviation (SD) for normally distributed data and median and interquartile range (IQR) for skewed data. Percentages will be reported as numbers (%). Comparisons of proportions will be made using chi-squared tests for equal proportions and continuous variables using the Independent Samples t-Test or the Wilcoxon Rank Sum Test. A p-value < 0.05 will be considered statistically significant. Analyses will be performed using Stata Statistical Software: Release 14. College Station, TX: StataCorp LP by a Statistician. Subgroups defined apriori are proposed where there are 10 or more patients in each arm.

Summary
Brief summary
When people are critically ill and require treatment in an Intensive Care Unit, they are often unable to eat food. In this situation the standard treatment is to supply them with food dripped into their stomach or bowel through a feeding tube (termed enteral nutrition). Enteral nutrition provides both macronutrients (carbohydrates, protein and fat) and micronutrients (vitamins, minerals and trace elements). In Australia, enteral nutrition formula composition is guided by the National Health and Medical Research Council (NHMRC). These standards, termed Nutrient Reference Values (NRVs), include the recommended dietary intake (RDI), adequate intake (AI) and upper level of intake (UL). However, there is very little information on the amount of micronutrients delivered to critically ill patients during Intensive Care Unit admission. We are conducting a retrospective observational study to assist in determining the micronutrient intake of vitamins B12, D, C, A, iron, folate, thiamine, zinc, and selenium delivered from enteral nutrition to critically ill adults admitted to Box Hill Hospital Intensive Care Unit (ICU), Melbourne, Australia between January 2018 and January 2020. Micronutrient intake will be assessed for the first seven days of ICU admission and compared to Australian NRVs.
