Achieving enteral nutrition during the acute phase in critically ill children: Associations with patient characteristics and clinical outcome

Exploring paediatric dietetic resources available for critically ill children in the UK and Ireland: A multicentre survey

BACKGROUND

A dedicated intensive care dietitian, as part of the intensive care unit (ICU) multidisciplinary team, contributes to improved delivery of nutrition support. The Paediatric Critical Care Society recommends a minimum dietetic staffing to critical-care bed ratio of 1:10, led by an Agenda for Change (AfC) Band 7.

METHODS

A cross-sectional study was conducted using an electronic survey that was available for 12 weeks. The Paediatric Intensive Care Audit Network database was used to identify all hospitals with paediatric intensive care unit (PICU) beds (n = 28).

RESULTS

Only 14% (n = 4/28) of trusts met the recommended 1:10 dietitian to bed ratio. PICU dietetic whole time equivalent was 0.7 ± 0.4, with a staff to bed ratio of 1:23.7 ± 10.7, compared to adult staff to bed ratio of 1:24.7. Some 92.8% (n = 26/28) had a AfC Band 7 Lead and only 7% (n = 2/28) had an AfC Band 8a Lead compared to adult services where 12.5% (n = 15/122) had an AfC Band 8a (p < 0.05).

CONCLUSIONS

There is a significant disparity between adult versus paediatric services with regard to seniority of dietitians. Dietitians in well-resourced centres were more likely to review patients without the need for a referral, which may improve nutrition outcomes.

Nutrition provision in Australian and New Zealand PICUs: A prospective observational cohort study (ePICUre)

OBJECTIVES

The main aim of this study was to describe nutrition provision in Australian and New Zealand (ANZ) pediatric intensive care units (PICUs), including mode of nutrition and adequacy of enteral nutrition (EN) to PICU day 28. Secondary aims were to determine the proportion of children undergoing dietetics assessment, the average time to this intervention, and the methods for estimation of energy and protein requirements.

METHODS

This observational study was conducted in all ANZ tertiary-affiliated specialist PICUs. All children ≤18 y of age admitted to the PICU over a 2-wk period and remaining for ≥48 h were included. Data were collected on days 1 to 7, 14, 21, and 28 (unless discharged prior). Data points included oral intake, EN and parenteral nutrition support, estimated energy and protein adequacy, and dietetics assessment details.

RESULTS

We enrolled 141 children, of which 79 were boys (56%) and 84 were <2 y of age (60%). Thirty children (73%) received solely EN on day 7 with documented energy and protein targets for 22 (73%). Of these children, 14 (64%) received <75% of their estimated requirements. A dietetics assessment was provided to 80 children (57%), and was significantly higher in those remaining in the PICU beyond the median length of stay (41% in patients staying ≤4.6 d versus 72% in those staying >4.6 d; P < 0.001).

CONCLUSIONS

This prospective study of nutrition provision across ANZ PICUs identified important areas for improvement, particularly in EN adequacy and nutrition assessment. Further research to optimize nutrition provision in this setting is urgently needed.

Continuous versus Intermittent Enteral Feeding in Critically Ill Children: A Systematic Review

Administration of enteral nutrition (EN) in critically ill pediatric patients admitted to the pediatric intensive care unit (PICU) constitutes a major challenge due to the increased risk of complications, as well as the lack of well-trained healthcare professionals. EN is usually delivered via cyclic, continuous, or intermittent feeding; however, a number of potential barriers have been reported in the literature regarding different feeding regimens. The purpose of this review was to assess the effectiveness of continuous and intermittent bolus feeding on critically ill children. A systematic search was conducted in PubMed, Scopus Cochrane Central Register of Controlled Trials (CENTRAL) and a clinical trial registry up to September 2022, including randomized controlled trials (RCTs) published in the English language. Four studies met the inclusion criteria with a total population of 288 patients admitted to the PICU. Three studies were rated with a high risk of bias and one with some concerns. There was high heterogeneity between the studies in regard to the reporting of outcomes. Three studies measured the total time needed to reach prescribed caloric intake with conflicting results, while two studies evaluated the length of stay (LOS) in PICU with no difference between the two arms. One study assessed the time weaning from mechanical ventilation, favoring the bolus group. No data were provided for gastric residual volume (GRV), anthropometric measurements, and biochemical markers. Additional randomized trials with better methodology are needed to assess the efficacy of the two enteral feeding regimens in critically ill PICU patients.

Intermittent versus continuous enteral nutrition in critically ill children: A pre-planned secondary analysis of an international prospective cohort study

BACKGROUND & AIMS

Intermittent enteral nutrition (EN) may have physiologic benefits over continuous feeding in critical illness. We aimed to compare nutrition and infection outcomes in critically ill children receiving intermittent or continuous EN.

METHODS

International, multi-center prospective observational study of mechanically ventilated children, 1 month to 18 years of age, receiving EN. Percent energy or protein adequacy (energy or protein delivered/prescribed × 100) and acquired infection rates were compared between intermittent and continuous EN groups using adjusted-multivariable and 4:1 propensity-score matched (PSM) analyses. Sensitivity analyses were performed after excluding patients who crossed over between intermittent and continuous EN.

RESULTS

1375 eligible patients from 66 PICUs were included. Patients receiving continuous EN (N = 1093) had a higher prevalence of respiratory illness and obesity, and lower prevalence of neurologic illness and underweight status on admission, compared to those on intermittent EN (N = 282). Percent energy or protein adequacy, proportion of patients who achieved 60% of energy or protein adequacy in the first 7 days of admission, and rates of acquired infection were not different between the 2 groups in adjusted-multivariable and propensity score matching analyses (P > 0.05).

CONCLUSION

Intermittent versus continuous EN strategy is not associated with differences in energy or protein adequacy, or acquired infections, in mechanically ventilated, critically ill children. Until further evidence is available, an individualized feeding strategy rather than a universal approach may be appropriate.
