Nutritional optimisation is recognised as having significant impact on clinical and functional outcomes of critically ill patients.
Clinical recommendations suggest use of indirect calorimetry guided nutrition in the intensive care unit (ICU), and a recent systematic review demonstrated improved outcomes from its use.
The COVID-19 pandemic has seen a greater proportion of patients with prolonged critical illness, a cohort for whom nutritional optimisation is a key unmet need.
This service evaluation recorded measurements of REE and RQ in critically ill patients with high lengths of ICU stay (up to 66 days), using Q-NRG device. We observed increased rates of overfeeding with increased duration of ICU admission, and increased overfeeding in non-obese patients.
