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.
Interventions
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 reco

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.
