Nutritional gap after transfer from the intensive care unit to a general ward - A retrospective quality assurance study

Background: Adequate nutrition is important for recovery after critical illness. Even so, our knowledge of patients' nutritional intake after intensive care unit (ICU) discharge is scarce.

Objectives: We aimed to explore nutritional planning and achieved nutritional intake in ICU patients who transfer from the ICU to general wards.

Methods: A retrospective quality assurance study.

Inclusion criteria: adult ICU patients transferring to a general ward at Copenhagen University Hospital-Herlev from May to August 2021. Primary outcomes were as follows: having a nutritional plan on the day of ICU transfer. A nutritional plan was defined as follows: (i) individual assessment of energy and protein requirement; (ii) intake, documented as achieved percentage of energy and protein requirements; (iii) prescribed type of nutrition. If using enteral or parenteral nutrition; (iv) the prescribed doses; and (v) the prescribed product. Secondary outcomes were as follows: achieved percentage of energy and protein requirements from day -1 before ICU transfer until day +1 and day +3 after ICU transfer.

Results: We included 57 patients; the mean age was 64 years (±11.1); 43 (75%) patients were male; the median ICU stay was 6 days (interquartile range: 3-11). One (2%) patient had a full nutritional plan according to listed criteria. Patients' median percentage of requirements met declined significantly from the day before to the day after ICU discharge (energy: from 94% to 30.5%; p = 0.0051; protein: from 73% to 27.5%; p = 0.0117). The decline in percentage of requirements met remained unchanged from day 1 to 3 after ICU transfer.

Conclusions: In conclusion, few patients had a nutritional plan when transferring from the ICU to a general ward. After ICU discharge, percentage of energy and protein requirements met declined significantly and remained insufficient during the first 3 days at the general ward.
