Role of the neonatal registered dietitian nutritionist in Canada: A description of staffing and a comparison to practices in the United States.

BACKGROUND: Neonatal registered dietitian nutritionists (RDNs) are critical members of the neonatal intensive care unit (NICU) team. Ideal RDN staffing levels are unknown. Current staffing levels of neonatal RDNs in Canadian NICUs have not been recently reported. The objective of this study was to describe neonatal RDN staffing and responsibilities in Canada and contrast these findings with those of neonatal RDNs in the United States. METHODS: An online cross-sectional neonatal RDN survey was performed in the Fall of 2021 to collect hospital-level and individual-RDN-level data. Descriptive statistics were performed to summarize Canadian neonatal RDN staffing levels and responsibilities and compared with US findings. RESULTS: Canadian RDNs reported a median staffing ratio of 25.3 NICU beds per RDN full-time equivalent, with neonatal RDNs reporting a desired 31% increase in staffing. The majority of Canadian NICUs (n = 20/24) reported having a dedicated space to prepare infant feeds away from bedside. Canadian neonatal RDNs reported wanting to expand their responsibilities in research, administration, and education. Canadian neonatal RDNs reported a higher rate of order writing privileges as compared with that of US neonatal RDNs. CONCLUSION: Canadian neonatal RDNs reported a desired increase in their staffing levels. Neonatal RDNs have the potential to expand their professional role but require additional staffing, dedicated time, and compensation to support this. Further research determining the optimal neonatal RDN staffing ratio to maximize patient outcomes is required.

US neonatal intensive care unit registered dietitian nutritionists salary description and correlates: results of a survey.

BACKGROUND: This survey described the compensation of neonatal intensive care unit (NICU) registered dietitian nutritionists (RDNs) in the United States and examined correlates of higher salaries within this group. METHODS: A cross-sectional online survey was completed in 2021 by 143 NICU RDNs from 127 US hospitals who reported hourly wage in US dollars (USD). We used initial bivariate analyses to assess the relationship of selected institution-level and individual-level variables to hourly wage; the rank-sum test for binary variables; bivariate regression and Pearson correlation coefficients for continuous variables; the Kruskal-Wallis test for categorical variables. Variables with a compelling relationship to the hourly wage outcome were considered in model creation. Final model selection was based on comparisons of model fit. RESULTS: Median hourly compensation was USD 33.24 (interquartile range [IQR] 29.81, 38.49). Seven variables had a compelling bivariate relationship with hourly wage: cost of living, employer facility with a paediatric residency, employer facility with a neonatal fellowship, NICU bed: full-time equivalents (FTE) RDN ratio, years in neonatal nutrition, having a certification and order writing privileges. In the final adjusted model (R2 = 0.42), three variables remained associated with increased hourly wage: higher cost of living, longer length of career in neonatal nutrition and fewer NICU beds per NICU RDN FTE. CONCLUSIONS: US NICU RDNs earn similar or slightly higher wages than other US paediatric RDNs; they earn substantially less than other NICU healthcare team members. Employers need to improve compensation for NICU RDNs to incentivise their retention and recognise their additional non-clinical responsibilities.

Expected and Desirable Preterm and Small Infant Growth Patterns.

Adequate nutrition is necessary for achieving optimal growth and neurodevelopment. Growth is a natural and expected process that happens concomitantly with rapid advancements in neurodevelopment. Serial weight, length, and head circumference growth measures are essential for monitoring development, although identifying pathological deviations from normal growth can pose challenges. Appropriate growth assessments require considerations that a range of sizes for length, head circumference, and weight are expected and appropriate. Because of genetic differences and morbidities, there is a considerable overlap between the growth of healthy infants and those with growth alterations. Parents tend to be over-concerned about children who plot low on growth charts and often need reassurance. Thus, the use of terms such as "poor" growth or growth "failure" are discouraged when growth is approximately parallel to growth chart curves even if their size is smaller than specific percentiles. No specific percentile should be set as a growth goal; individual variability should be expected. An infant's size at birth is important information that goes beyond the common use of prognostic predictions of appropriate compared with small or large for gestational age. The lower the birthweight, the lower the nutrient stores and the more important the need for nutrition support. Compared to term infants, preterm infants at term-equivalent age have a higher percentage of body fat, but this diminishes over the next months. Current research findings support expert recommendations that preterm infants should grow, after early postnatal weight loss, similar to the fetus and then term-born infants, which translates to growth approximately parallel to growth chart curves. There is no need for a trade-off between optimum cognition and optimum future health. Each high-risk infant needs individualized nutrition and growth assessments. This review aims to examine infant growth expectations and messaging for parents of preterm and term-born infants within the broader causal framework.

The Role of the Neonatal Registered Dietitian Nutritionist: Past, Present, and Future.

Neonatal registered dietitian nutritionists (RDNs) are critical members of the neonatal intensive care unit (NICU) team due to their unique skillset of growth assessment, nutrition evaluation, and implementation of nutrition best practices. There is a paucity of data on appropriate staffing of neonatal RDNs in NICUs to promote improved patient outcomes. Here, the authors describe current neonatal RDN staffing and responsibilities in the US NICUs.

Targeted fortification with human milk analysis: An opportunity for innovation.

Human milk's variable macronutrient composition is a necessary consideration when caring for very low birthweight infants. Targeted fortification is the practice of fortifying human milk using its known composition from human milk analysis, rather than its assumed macronutrient values. Utilization of human milk analyzers to measure the protein, fat, lactose, and energy composition within human milk samples has allowed the translation of this practice into the clinical setting. This review discusses the rationale of why targeted fortification is an important practice, what barriers exist in its implementation in the clinical setting, and what research gaps remain to be addressed.

Effect of parenteral nutrition duration on patterns of growth and body composition in very low-birth-weight premature infants.

BACKGROUND: Parenteral nutrition (PN) is essential to support premature infants' growth and varies with enteral nutrition (EN) advancement rates. Data on PN duration's impact on premature infants' growth are limited. The aim of this multicenter observational study was to determine the effect of early PN duration on body composition at term corrected gestational age (CGA) in very low-birth-weight (VLBW) premature infants. METHODS: VLBW infants exposed to PN in the first week of life and exposed to significantly different EN regimens were divided into two groups on the basis of early PN duration. Infants with a birth weight (BW) <1000 g and PN duration <28 days and infants with a BW 1000-1500 g and PN duration <14 days were assigned to the "short-PN" group. Infants receiving PN for longer durations were assigned to the "long-PN" group. Body composition was assessed via air displacement plethysmography at term CGA or before discharge. RESULTS: Sixty-two and 53 infants were assigned to the short-PN and long-PN groups, respectively. The two groups were significantly different in BW and GA, so a nested case-control study was conducted after matching 36 infant pairs. Infants in the long-PN group had significantly lower fat-free mass (FFM) z-scores, but both groups had comparable fat mass (FM) z-scores. Long PN was a significant negative predictor of FFM z-score in the multivariate regression analysis. CONCLUSION: In VLBW premature infants, PN duration is negatively associated with FFM z-scores at term CGA without affecting FM z-scores.

Exploring Innovations in Human Milk Analysis in the Neonatal Intensive Care Unit: A Survey of the United States.

Introduction: Human milk (HM) is the ideal enteral feeding for nearly all infants and offers unique benefits to the very low birthweight (VLBW) infant population. It is a challenge to meet the high nutrient requirements of VLBW infants due to the known variability of HM composition. Human milk analysis (HMA) assesses the composition of HM and allows for individualized fortification. Due to recent U.S. Food and Drug Administration (FDA) approval, it has relatively recent availability for clinical use in the US. Aim: To identify current practices of HMA and individualized fortification in neonatal intensive care units (NICUs) across the United States (US) and to inform future translational research efforts implementing this nutrition management method. Methods: An institutional review board (IRB) approved survey was created and collected data on the following subjects such as NICU demographics, feeding practices, HM usage, HM fortification practices, and HMA practices. It was distributed from 10/30-12/21/2020 via online pediatric nutrition groups and listservs selected to reach the intended audience of NICU dietitians and other clinical staff. Each response was assessed prior to inclusion, and descriptive analysis was performed. Results: About 225 survey responses were recorded during the survey period with 119 entries included in the analysis. This represented 36 states and Washington D.C., primarily from level III and IV NICUs. HMA was reported in 11.8% of responding NICUs. The most commonly owned technology for HMA is the Creamatocrit Plus TM (EKF Diagnostics), followed by the HM Analyzer by Miris (Uppsala, Sweden). In NICUs practicing HMA, 84.6% are doing so clinically. Discussion: Feeding guidelines and fortification of HM remain standard of care, and interest in HMA was common in this survey. Despite the interest, very few NICUs are performing HMA and individualized fortification. Barriers identified include determining who should receive individualized fortification and how often, collecting a representative sample, and the cost and personnel required. Conclusions: Human milk analysis and individualized fortification are emerging practices within NICUs in the US. Few are using it in the clinical setting with large variation in execution among respondents and many logistical concerns regarding implementation. Future research may be beneficial to evaluate how practices change as HMA and individualized fortification gain popularity and become more commonly used in the clinical setting.

Infant body composition assessment in the neonatal intensive care unit (NICU) using air displacement plethysmography: Strategies for implementation into clinical workflow.

Nutritional management is integral to infant care in the neonatal intensive care unit (NICU). Recent research on body composition that specifically evaluated fat and fat-free mass has improved our understanding of infant growth and nutritional requirements. The need for body composition monitoring in infants is increasingly recognized as changes in fat mass and fat-free mass associated with early growth can impact clinical outcomes. With the availability of air displacement plethysmography (ADP) as a noninvasive method for assessing infant body composition and published normative gestational age- and sex-specific body composition curves, it is justifiable to integrate this innovation into routine clinical care. Here we describe our experiences in implementing body composition measurement using ADP in routine clinical care in different NICU settings.

Donor Breast Milk for the Preterm Infant: Your Questions Answered!

Expressed breast milk (EBM) is the gold standard of infant nutrition, but is not always available for use for preterm infants in the NICU setting. Donor breast milk (DBM) is often a preferred alternative for preterm and very low birth weight (VLBW) infants when maternal milk is not available. This article discusses the composition of DBM, reviews its advantages compared to formula, discusses challenges related to its long-term use, and identifies strategies to utilize DBM in the context of total nutritional management of preterm and VLBW infants. We will use a framework of WHO, WHAT, WHERE, WHEN, and WHY to answer the questions: who gets DBM, why use DBM, where does DBM come from, what is in DBM, and when may DBM use be challenged.
