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.

When parenteral nutrition is the answer: The case of pediatric intestinal rehabilitation

In pediatric patients with intestinal failure, parenteral nutrition is lifesaving but also has several associated risks. The goals of intestinal rehabilitation include promoting growth, minimizing complications associated with intestinal failure, and reaching enteral autonomy, if possible. Pediatric intestinal rehabilitation programs are interdisciplinary teams that strive to provide optimal care for children dependent on parenteral nutrition. The provision of parenteral nutrition requires close monitoring of patients' growth, nutrition concerns, clinical status, and laboratory parameters. Recent advances in the field of intestinal rehabilitation include new lipid emulsions, considerations regarding enteral feeding, advances in micronutrient provision, and central venous catheter preservation techniques. Challenges in the field remain, including improving overall quality of life with home parenteral nutrition administration and preventing recently recognized complications such as chronic intestinal inflammation.

Nutritional Support Best Practices in Pediatric Blood and Marrow Transplant Patients: An Integrative Review

Nutrition is vital to the long-term survival of children undergoing blood and marrow transplantation (BMT), but there is no standardization on how to optimize the nutritional status of these patients. A literature search was performed to evaluate nutritional support approaches currently in practice for pediatric patients who are undergoing BMT. CINAHL, Embase, and Cochrane databases were searched for peer-reviewed articles evaluating nutritional interventions for BMT recipients aged 20 or younger. Nine articles published between 2019 and 2023 were found and reviewed. The nutritional support varied between enteral nutrition, parenteral nutrition, a combination of both, and prophylactic feeding tube placement. The post-transplant outcomes identified as associated with alterations in nutritional regimens included length of stay, date of platelet engraftment, incidence of acute graft-versus-host disease, infection rate, and overall survival. The use of any amount of enteral nutrition compared to parenteral alone was beneficial. Complications during BMT can potentially be decreased via prioritizing enteral nutrition over parenteral. The paucity of literature on this topic highlights an unmet need in the field. Future research should focus on ways to optimize the nutritional support of transplant recipients, including increasing the likelihood of enteral feeding tube placement and utilization.

Using Quality Improvement to Improve Identification and Documentation of Malnutrition in Hospitalized Pediatric Patients

Recent publications have highlighted the importance and impact of recognizing malnutrition in hospitalized children. After noting that patients with malnutrition frequently went unrecognized in our facility, we implemented an interprofessional intervention comprising hospital medicine physicians, dietitians, and the clinical documentation improvement team to improve recognition and documentation of malnutrition in these patients, thereby facilitating earlier intervention.

Comparison of three different nutrition screening tools for pediatric inpatients

BACKGROUND

Early detection of children at risk of developing malnutrition during hospitalization prevents the development of complications. This study aims to determine the malnutrition risk of pediatric inpatients by using three different nutrition screening tools and to evaluate the reliability/sensitivity of the screening tools.

METHODS

This cross-sectional study included 176 children who were 1-16 years of age and were admitted to the pediatrics service of a second-line hospital. Body weight and height were used to evaluate the nutrition status of children. Age- and sex-specific z-score values for height for age (HFA), weight for age (WFA), and body mass index for age (BFA) were indicators of malnutrition. The Screening Tool for Risk of Impaired Nutritional Status and Growth (STRONGkids), Pediatric Yorkhill Malnutrition Score (PYMS), and Pediatric Nutrition Screening Tool (PNST) were used under the responsibility of pediatricians and dietitians to evaluate the risk of malnutrition in children.

RESULTS

At admission, according to the HFA, BFA, and WFA SD scores (SDSs), the incidence of malnutrition in children was 8.5%, 14.8%, and 6.3%, respectively. Three screening tools determined that WFA SDSs were significantly higher in children without malnutrition risk than in those at risk of malnutrition (P < 0.05). PYMS revealed a relatively higher sensitivity of 90.9% and 84.6% for WFA and BFA, respectively, and PNST revealed a relatively higher sensitivity of 88.9% for HFA.

CONCLUSIONS

PYMS and PNST are suitable for use in malnutrition risk assessment in pediatric inpatients because of the screening tools' high sensitivity.

Academy of Nutrition and Dietetics and American Society for Parenteral and Enteral Nutrition: Revised 2021 Standards of Practice and Standards of Professional Performance for Registered Dietitian Nutritionists (Competent, Proficient, and Expert) in Nutrition Support

Nutrition support is a therapy that crosses all ages, diseases, and conditions as health care practitioners strive to meet the nutritional requirements of individuals who are unable to meet nutritional and/or hydration needs with oral intake alone. Registered dietitian nutritionists (RDNs), as integral members of the nutrition support team provide needed information, such as identification of malnutrition risk, macro- and micronutrient requirements, and type of nutrition support therapy (eg, enteral or parenteral), including the route (eg, nasogastric vs nasojejunal or tunneled catheter vs port). The Dietitians in Nutrition Support Dietetic Practice Group, American Society for Parenteral and Enteral Nutrition, along with the Academy of Nutrition and Dietetics Quality Management Committee, have updated the Standards of Practice (SOP) and Standards of Professional Performance (SOPP) for RDNs working in nutrition support. The SOP and SOPP for RDNs in Nutrition Support provide indicators that describe the following 3 levels of practice: competent, proficient, and expert. The SOP uses the Nutrition Care Process and clinical workflow elements for delivering patient/client care. The SOPP describes the 6 domains that focus on professional performance. Specific indicators outlined in the SOP and SOPP depict how these standards apply to practice. The SOP and SOPP are complementary resources for RDNs and are intended to be used as a self-evaluation tool for assuring competent practice in nutrition support and for determining potential education and training needs for advancement to a higher practice level in a variety of settings.

Development of a clinical practice guideline for weaning and discontinuing parenteral nutrition in hospitalized children as part of a central line-associated bloodstream infection-focused quality improvement initiative

BACKGROUND

Overprescribing of parenteral nutrition (PN) increases costs and risks to patients, including from central line-associated bloodstream infection (CLABSI). With CLABSI reduction in mind, our children's hospital began an iterative quality improvement effort to decrease PN utilization by first ensuring appropriate initiation and then defining and ensuring appropriate discontinuation.

METHODS

Education was launched along with audits to evaluate for appropriate PN indications. Next, a literature review was conducted to guide the development of an algorithm to appropriately wean and discontinue PN. Lastly, all PN discontinuations were audited for agreement with the new guideline. Retrospectively, monthly PN utilization index (orders per patient-day) was plotted on a statistical process control chart to assess change over time. The presence of PN as a risk factor for CLABSI events and the overall hospital CLABSI rate were trended.

RESULTS

Mean PN utilization index fell from 0.156 (July 2018 to January 2019) to 0.12 (February 2019 to August 2020) (P < .01). For 18 months, no PN utilization index reached the baseline lower control limit of 0.144, demonstrating special-cause variation and sustained change. PN as a risk factor for hospital CLABSI cases decreased from most prevalent (49% of cases) to fifth most prevalent (29%) as the CLABSI rate trended down.

CONCLUSION

Engaging frontline staff in the development of a clinical practice guideline and increased accountability to reduce potential patient harm led to a significant and sustained reduction in PN utilization, as well as decreased prevalence of PN as a risk factor in hospital CLABSI cases.

Nutrition risk profile of 62 408 inpatients based on electronic health records in a tertiary children's hospital

OBJECTIVES

This study aimed to evaluate the nutrition risk profile of hospitalized children with electronic health record-based nutrition risk screening. Additionally, this study analyzed the association between high nutrition risk and clinical outcomes.

METHODS

Children discharged from Shanghai Children's Medical Center between 2017 and 2018 were enrolled and nutritionally screened. Nutrition risk scores using the Screening Tool for Assessment of Malnutrition in Pediatrics (STAMP), length of stay (LOS), and costs of hospitalization were recorded. Enrolled patients were categorized into two groups: the low and medium nutrition risk (LMNR) group, with scores ranging from 0 to 3, and the high nutrition risk (HNR) group, with scores ≥4.

RESULTS

Out of 62 408 subjects, 17.4% were at HNR. Patients with congenital heart diseases (83.9%), hematology-oncology diseases (26.0%) and gastroenterological diseases (21.4%) were affected most. Infants had the highest HNR rates (35.5%) of any age group. Surgical patients (20.7%) had a higher rate of HNR than non-surgical patients (9.5%). The HNR group had longer LOS (10.0 d versus 3.0 d, P < 0.001), higher total hospital costs (53 680.1 Chinese yuan [CNY] versus 8810.1 CNY, P < 0.001), and higher costs of antibiotics (441.0 CNY versus 0.0 CNY, P < 0.001) compared to the LMNR group. As STAMP score values increased, growing LOS and costs of hospitalization, medications, and antibiotics were observed.

CONCLUSIONS

A high prevalence of HNR was found in patients of Shanghai Children's Medical Center. Surgeries, specific disease, and infancy were important HNR risk factors. HNR scores using STAMP might predict prolonged LOS and higher medical costs.

CONSTRUCTION AND VALIDATION OF THE NEONATAL NUTRITIONAL RISK SCREENING TOOL

Objective:

To develop and validate both the content and reliability of the Neonatal Nutritional Risk Screening Tool (FARNNeo).

Methods:

Methodological study, convergent care. The instrument was built prior to the literature review and was analyzed by eight judges, during three cycles of the Delphi technique. The judges assessed their relevance and clarity with responses on the Likert scale with three levels, in addition to suggestions. The validation of the instrument was calculated using the agreement rate and content validity index (CVI). After content validation, the instrument was applied by four assisting nutritionists to verify reliability, using Cronbach`s alpha coefficient and the agreement between the evaluators by the Kappa coefficient.

Results:

All items of the instrument`s content reached the minimum agreement rate (90%) and/or CVI (0.9), except for item three, which in the first cycle obtained CVI 0.77 and 40% of agreement and, in the second cycle, CVI 0.75 and 38% agreement. At the end of the third cycle, all items had CVI values above 0.9. In the instrument application, alpha of 0.96 and Kappa of 0.74 were obtained, which reflect adequate values of internal consistency and agreement between the evaluators.

Conclusions:

FARNNeo proved to be reliable, clear, relevant, and reproducible for tracking early nutritional risk, systematizing the care of Brazilian newborns admitted to an intensive care unit.

Validity and reliability of the Turkish version of three screening tools (PYMS, STAMP, and STRONG-kids) in hospitalized children

BACKGROUND

There are different malnutrition screening tools developed in the English language, but limited data available on the validity of their versions translated into other languages. The aim of this study is to construct a Turkish version of PYMS, STRONG-kids, and STAMP and to determine their validity and reliability in a pediatric population.

METHODS

The present study was conducted at two stages. First, the process of translating PYMS, STRONG-kids, and STAMP into the Turkish language was performed. In the second stage, the validity and reliability were evaluated in the new version of the tools. The anthropometric assessment was used as the reference standard in evaluating the validity of criteria. The reliability was observed through inter-rater and intra-rater agreement.

RESULTS

202 children in total were involved in the present study, 42 of whom took part in the reliability phase. The inter-rater agreement between one dietitian and one nurse was kappa (κ) = 0.955 (95% CI 0.904-1.000) for PYMS, 0.901 (95% CI 0.828-0.974) for STRONG-kids, and 0.963 (95% CI 0.912-1.000) for STAMP (almost perfect agreement). Sensitivity of the PYMS, STRONG-kids, and STAMP were 96.8%, 87.1%, and 77.4%, respectively. Specificity of the PYMS, STRONG-kids, and STAMP was found to be 65.0%, 30%, and 60.0%, respectively.

CONCLUSION

The inter-rater and intra-rater reliability of the three tools were determined to be good. While PYMS was found to be more sensitive in detecting the malnutrition risk when compared to the other tools, STRONG-kids had the lowest specificity according to the agreement between tool results and anthropometric assessment.

STRONGkids: Predictive Validation in Brazilian Children

OBJECTIVES

The aim of the study is to assess STRONGkids as a tool for predicting weight loss and length of hospital stay in children and to determine whether the anthropometric diagnosis of nutritional status at the time of admission was associated with weight loss and length of hospital stay.

METHODS

A methodological study recruiting 245 children age between 1 and 10 years of age admitted to a tertiary hospital. The participants were weighed daily until discharge. Validation of the STRONGkids tool for the identification of patients sustaining weight loss at the end of hospitalization involved the calculation of sensitivity, specificity, and positive and negative predictive values, and anthropometric assessment.

RESULTS

A total of 129 (52.7%) children lost weight at the end of hospitalization. Of these, 73 (56.6%) lost over 2% of their weight on admission. The tool had a sensitivity of 55.8%, a specificity of 38.8% and a positive predictive value of 50.3% in identifying children who lost weight. The anthropometric assessment had a sensitivity of 26.5%, a specificity of 75.9%, and a positive predictive value of 49.1%.

CONCLUSIONS

The model used to develop the STRONGkids tool incorporated clinical evaluation to a greater extent than the assessment of nutritional status. The tool, however, had a low sensitivity and a high percentage of false positives. Therefore, it should be considered as a preliminary evaluation tool and its use should be complemented with clinical data.

Evaluation of malnutrition development risk in hospitalized children

OBJECTIVES

Many screening methods, such as the Screening Tool Risk on Nutritional Status and Growth (STRONGkids) and the Pediatric Yorkhill Malnutrition Score (PYMS), have been developed to detect malnutrition in pediatric patients. We aimed to explore the prevalence of malnutrition risk in hospitalized children via symptoms and identification of contributing factors, and to examine the efficacy of malnutrition screening tools for hospitalized children.

METHODS

STRONGkids and PYMS were applied to 1513 inpatients at 37 hospitals in 26 cities from different regions of Turkey. Physical measurements were collected at hospital admission and at discharge. z-Scores of height-for-age, weight-for-age, weight-for-height, and body mass index-for-age were calculated.

RESULTS

Overall, 1513 patients were included in the study. A body mass index standard deviation score of less than -2 was present in 9.5% of the study population at hospital admission, whereas 11.2% of the participants had a weight-for-length/height score of less than -2 at hospital admission. According to STRONGkids results, the proportion of the patients with an underlying chronic disease was higher for the patients at high risk of malnutrition than for the patients at medium or low risk (91% compared with 47% or 45%, respectively). PYMS results indicated that patients at high risk of malnutrition have more chronic diseases (75%) than the patients at medium or low risk of malnutrition (55% and 44%, respectively).

CONCLUSIONS

Use of anthropometric measurements in addition to screening tools to identify hospital malnutrition (such as PYMS, STRONGkids) will prevent some nutritional risk patients from being overlooked.

Reproducibility and Inter-rater Reliability of 2 Paediatric Nutritional Screening Tools

OBJECTIVES

The aim of the present study was to assess reproducibility and inter-rater reliability of 2 nutritional screening tools (NST): Screening Tool for Risk on Nutritional Status and Growth (STRONGkids) and Screening Tool for the Assessment of Malnutrition in Paediatrics (STAMP).

METHODS

Prospective observational multicentre study. Patients ages 1 month or older admitted to paediatric or surgical wards were tested within 24 hours of admission by 2 independent observers: experts specialized in paediatric nutrition (physicians or dieticians) and clinical staff nonexpert in nutrition. Diagnosis on admission, underlying diseases, and length of stay were registered.

STATISTICAL ANALYSIS

Kappa index (κ) to evaluate agreement between observers.

RESULTS

A total of 223 patients were included (53.4% boys), with mean age of 5.59 (95% confidence interval 4.94-6.22) years. Experts classified 9.9% of patients at high risk with STRONGkids and 19.7% using STAMP, whereas nonexpert staff assigned 6.7% of patients to the high-risk category with STRONGkids and 21.9% with STAMP. Agreement between expert and nonexpert staff was good: 94.78% for STRONGkids (κ 0.72 [P < 0.001]); 92.55% for STAMP (κ 0.74 [P < 0.001]). The rate of malnutrition was significantly higher among high-risk patients with both NST, independent of examiner experience. After adjusting for age, both STRONGkids and STAMP high-risk scores predicted longer length of stay, whether assessed by experts or nonexperts, although differences were higher with STRONGkids.

CONCLUSIONS

Agreement between experts and nonexpert staff in nutrition was good, producing a similar high-risk patient profile. Our results demonstrate that these NSTs are appropriate for nutritional screening in settings in which users have no previous experience in the field.

When Is Parenteral Nutrition Appropriate?

Parenteral nutrition (PN) represents one of the most notable achievements of modern medicine, serving as a therapeutic modality for all age groups across the healthcare continuum. PN offers a life-sustaining option when intestinal failure prevents adequate oral or enteral nutrition. However, providing nutrients by vein is an expensive form of nutrition support, and serious adverse events can occur. In an effort to provide clinical guidance regarding PN therapy, the Board of Directors of the American Society for Parenteral and Enteral Nutrition (ASPEN) convened a task force to develop consensus recommendations regarding appropriate PN use. The recommendations contained in this document aim to delineate appropriate PN use and promote clinical benefits while minimizing the risks associated with the therapy. These consensus recommendations build on previous ASPEN clinical guidelines and consensus recommendations for PN safety. They are intended to guide evidence-based decisions regarding appropriate PN use for organizations and individual professionals, including physicians, nurses, dietitians, pharmacists, and other clinicians involved in providing PN. They not only support decisions related to initiating and managing PN but also serve as a guide for developing quality monitoring tools for PN and for identifying areas for further research. Finally, the recommendations contained within the document are also designed to inform decisions made by additional stakeholders, such as policy makers and third-party payers, by providing current perspectives regarding the use of PN in a variety of healthcare settings.

Enteral Nutrition in the PICU: Current Status and Ongoing Challenges

Malnutrition in the critically ill or injured child is associated with increased morbidities and mortality in the pediatric intensive care unit (PICU), whether present upon admission or acquired during the PICU stay. Particular subpopulations such as those with congenital heart disease or severe thermal injury are at highest risk for malnutrition which can worsen with illness progression. A growing body of evidence suggests the presence of a positive association between nutrition support during critical illness and patient outcomes. Enteral nutrition (EN), the preferred route of nutrient delivery, may be a crucial component of care provided in the PICU which modifies the response to critical illness or injury, resulting in improved outcomes. Numerous challenges exist in the delivery of the EN goal in critically ill children. These include accurate assessment of nutrient requirements, hemodynamic instability, feeding intolerance, feeding interruptions, and the lack of a standardized approach to nutrition support. This article describes the current state of the science and challenges related to EN prescription and delivery in the critically ill child. Suggestions for improving EN practice are then presented, in addition to a platform for further research inquiry.

Cost-effectiveness analysis of an enteral nutrition protocol for children with common gastrointestinal diseases in China: good start but still a long way to go

BACKGROUND

A standard nutrition screening and enteral nutrition (EN) protocol was implemented in January 2012 in a tertiary children's center in China. The aims of the present study were to evaluate the cost-effectiveness of a standard EN protocol in hospitalized patients.

METHODS

A retrospective chart review was performed in the gastroenterology inpatient unit. We included all inpatient children requiring EN from January 1, 2010, to December 31, 2013, with common gastrointestinal (GI) diseases. Children from January 1, 2012, to December 31, 2013, served as the standard EN treatment group, and those from January 1, 2010, to December 31, 2011, were the control EN group. Pertinent patient information was collected. We also analyzed the length of hospital stay, cost of care, and in-hospital infection rates.

RESULTS

The standard EN treatment group received more nasojejunal tube feedings. There was a tendency for the standard EN treatment group to receive more elemental and hydrolyzed protein formulas. Implementation of a standard EN protocol significantly reduced the time to initiate EN (32.38 ± 24.50 hours vs 18.76 ± 13.53 hours; P = .011) and the time to reach a targeted calorie goal (7.42 ± 3.98 days vs 5.06 ± 3.55 days; P = .023); length of hospital stay was shortened by 3.2 days after implementation of the standard EN protocol but did not reach statistical significance. However, the shortened length of hospital stay contributed to a significant reduction in the total cost of hospital care (13,164.12 ± 6722.95 Chinese yuan [CNY] vs 9814.96 ± 4592.91 CNY; P < .032).

CONCLUSIONS

Implementation of a standard EN protocol resulted in early initiation of EN, shortened length of stay, and significantly reduced total cost of care in hospitalized children with common GI diseases.

Validity of nutritional screening tools for hospitalized children

Background. Malnutrition in hospitalized children can be prevented if children with risk of malnutrition are identified. Every hospital is recommended to have a standard nutritional screening tool. Numerous simple screening tools have been developed, namely Paediatric Yorkhill Malnutrition Score (PYMS), Screening Tool for the Assessment of Malnutrition in Paediatrics (STAMP), and Screening Tool for Risk on Nutritional Status and Growth (STRONG-kids). None has been accepted as a universal tool. Our study aims to determine the best screening tools compared to Subjective Global Nutrition Assessment (SGNA), an assessment tool which is more complex as our gold standard. Methods. This diagnostic study involved 116 patients aged 1–15 years. Three screening tools and SGNA were examined to each subject. Statistical analysis was used to determine sensitivity, specificity, and likelihood ratio (LR) by results from screening tools divided into low and moderate-high risk of malnutrition compared to results from SGNA divided into no and moderate-severe malnutrition. Results. PYMS showed superior agreement to SGNA resulting in sensitivity 95.32%, specificity 76.92%, positive LR 4.13, and negative LR 0.061. STAMP resulted in sensitivity, specificity, positive LR, and negative LR, respectively, as 100%, 11.54%, 1.13, and 0 and STRONG-kids resulted in 100%, 7.7%, 1.083, and 0. Conclusion. PYMS was the most reliable screening tool.
