Proactive enteral nutrition for patients undergoing allogeneic stem cell transplantation- implementation and clinical outcomes.

BACKGROUND/ OBJECTIVES: Nutrition support is frequently required post allogeneic haematopoietic progenitor cell transplantation (HPCT) however the tolerance of enteral nutrition (EN) can vary. This mixed methods study aimed to explore staff perceptions, barriers and enablers to the use of EN post HPCT and report the implementation and outcomes of a nutrition protocol. SUBJECT/ METHODS: A survey on barriers and enablers to the use of EN was developed and distributed to medical and nursing staff. Data on nutrition and clinical outcomes was collected for 12 months post implementation of a new nutrition protocol. RESULTS: Thirty staff completed the survey, key barriers identified included uncertain EN tolerance, lack of confidence in nasogastric tube placement and insufficient training and resources. Eighty-four patients commenced EN, 23 changed to PN (27%) and 61 received EN only (73%). In total 36 patients received PN and eight patients oral nutrition support only. There was a difference in type of conditioning (p = 0.025) and nutritional status (p = 0.016) between patients who received PN vs EN only, with a higher proportion of malnourished patients receiving PN (23% vs 5%). Patients who received PN had a longer length of hospital stay (median 22 vs 19 days, p = 0.012) and lower rate of survival to day 100 (81% vs 95%, p = 0.036) than patients who received EN. CONCLUSION: The use of EN may lead to improved clinical outcomes compared to PN therefore should be implemented as first line nutrition support.
