Nutrition in critical care: An audit of protein and energy intakes compared to international recommendations

ABSTRACT

Adequate protein and energy provision in critical care is associated with better clinical outcomes. The aim of this audit was to evaluate compliance with achieving recommended protein and energy targets in our Intensive Care Unit (ICU) and to explore the reasons for any deficits identified. Nutrition parameters were collected on patients admitted to our ICU between March and May 2021. Inclusion criteria were requirement for nutritional support and mechanical ventilation with an ICU length of stay ≥ 4 days. Patients with COVID19 were excluded. Protein and energy intakes were compared to best practice guidelines1. 51 patients met the inclusion criteria 53% male, 47% female. Mean age was 59.6 years and mean length of stay was 19.9 days (range 5-61 days). Protein and energy intakes achieved as follows [Formula presented] Of the patients who received < 80% of their nutritional requirements, the main barriers to achieving targets identified were fasting and constipation in this cohort. Cumulative deficit ranged from 0 - 903g protein and 0 - 12717kcal over duration of ICU stay. Mean deficit was 315g protein and 2945kcal. Of concern, 12 patients had a deficit of > 500g protein and 7 patients had > 5000kcal deficit. While 69% of patients met ≥ 80% protein requirements and 77% of patients met ≥ 80% energy requirements, we have identified areas to consider to improve nutritional adequacy including increasing awareness of minimising fasting times and the introduction of a bowel management protocol.
