Research Priorities for Pediatric Intensive Care Nutrition Within the United Kingdom: A National Institute of Health Research James Lind Alliance Priority Setting Partnership.

ABSTRACT

OBJECTIVES: To determine research priorities in PICU nutrition, which represent the shared priorities of patients, parents, carers, and PICU healthcare professionals within the United Kingdom. DESIGN: A national multiphase priority setting methodology in partnership with the James Lind Alliance delivered over 16 months (June 2020-September 2021). Part 1 a national scoping survey asked respondents to submit their research uncertainties related to PICU nutrition. Part 2 summarizing and evidence-checking the submitted uncertainties. Part 3 interim prioritization survey. Part 4 consensus workshop. SETTING: PICU. PARTICIPANTS: Patients, parents, and carers of patients who had been admitted to PICU, and PICU healthcare professionals involved in the treatment of these patients within the United Kingdom. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: A national scoping survey asked respondents to submit their research uncertainties related to PICU nutrition. In the first survey, 165 topic ideas were suggested (12% by parents/carers and 88% by PICU healthcare professionals). These were categorized into 57 summary questions. The existing evidence was searched to ensure that the proposed summary questions had not already been answered. Forty were judged to be true uncertainties following a systematic literature review. These 40 uncertainties were grouped into eight themes for the second interim survey, which asked respondents to prioritize their top research questions. One hundred and forty participants contributed to this second interim survey. A final shortlist of 25 questions was derived, with the top 18 questions taken to a multistakeholder workshop where a consensus was reached on the top 10 priorities. CONCLUSIONS: This research identified important research gaps in the management of patients in PICU. Areas that need to be addressed as a priority include energy requirements in ventilated neonates, nutritional supplementation of probiotics to manage and prevent sepsis, the impact of postintensive care syndrome on nutrition and growth, and when to commence parenteral (IV) nutrition. The challenge now is to refine and deliver answers to these research priorities.
