[Process for the Implementation of Evidence-Based Parenteral Nutrition in German Perinatal Centres - Outcomes of a Multidisciplinary Network]

INTRODUCTION

Parenteral nutrition, usually indicated for preterm infants with a birthweight<1500 g and sick newborns, enables the supply with critical nutrients. As a high degree of therapy safety is required, a European guideline provides recommendations for safe therapy procedures. The present project aimed to evaluate the implementation of the European guideline in German perinatal centers and to identify possible barriers that impede its implementation. A further goal was to develop solution approaches to overcome possible barriers.

METHODS AND RESULTS

A multidisciplinary cooperation conducted an online survey questioning the current implementation procedures of the European guideline among pediatricians and hospital pharmacists. Results show barriers in the provisioning process of parenteral nutrition that hinder a guideline-compliant implementation in practice. Based on results of this survey, an expert network developed an interactive toolkit with simplified guideline recommendations, guideline-compliant advice for practice, best-practice examples, forms, and handouts. It seeks to encourage critical reflection of routine processes and provides concrete solutions to overcome barriers in practice.

CONCLUSION

The current procedures related to parenteral nutrition deviate from guideline recommendations. The developed toolkit provides practice-oriented support aiming to enhance the guideline-compliant implementation of parenteral nutrition in perinatal centers.

Parenterale Ernährung in deutschen Perinatalzentren

Hintergrund

Die Leitlinien der „European Society for Paediatric Gastroenterology, Hepatology and Nutrition“ (ESPGHAN) liefern evidenzbasierte Empfehlungen zu parenteraler Ernährung (PE) von Frühgeborenen und kranken Neugeborenen. Im Jahr 2013 wurde gezeigt, dass sie in Westeuropa nur teilweise angewendet werden und ihre klinische Implementierung verbessert werden sollte.

Ziel der Arbeit

Ziel dieser Arbeit ist, die derzeitige Anwendung der ESPGHAN-Leitlinien in Deutschland sowie Barrieren, die die Umsetzung verhindern, abzubilden.

Material und Methoden

Zusammen mit einer Expertengruppe und Institutionen aus dem deutschsprachigen Raum hat die „European Foundation for the Care of Newborn Infants“ (EFCNI) eine Befragung durchgeführt. Mit einem Online-Fragebogen wurden Pädiaterinnen/Pädiater (PÄD) und Krankenhausapothekerinnen/Krankenhausapotheker (KHA) aus deutschen Perinatalzentren und Krankenhausapotheken bezüglich der Umsetzung der Leitlinien befragt. Die Ergebnisse wurden qualitativ und quantitativ ausgewertet.

Ergebnisse und Diskussion

Von 558 angeschriebenen Kontakten wurden 196 gültige Umfragen ausgewertet. Nach Eigenangaben wenden 77 % der PÄD und 48 % der KHA die ESPGHAN-Leitlinien an. Barrieren wurden innerhalb der klinischen Anwendung identifiziert und waren teilweise struktureller und/oder organisatorischer Natur. Verbesserungsbedarf wurde in der Bereitstellung von parenteralen Standardlösungen, insbesondere am Wochenende, und elektronischen Verordnungssystemen, der Verabreichung von Lipiden bereits am 1. Lebenstag und der regelmäßigen Beurteilung aller Laborparameter beobachtet.

Ernährungsmanagement bei mangelernährten Kindern in der häuslichen Pflege - Empfehlungen aus einer settingspezifischen Leitlinie

Nutritional management in malnourished children and adolescents in home care - recommendations from a setting-specific evidence-based guideline Abstract. Background: Malnutrition in children is an underestimated phenomenon that is frequently unrecognized and therefore not adequately treated. If the treatment is inadequate, malnutrition can lead to a variety of negative consequences for the childrens' development. Corresponding guidelines for malnutrition for pediatric nursing in home care settings are lacking. Aim: The aim of this paper is to present the nutritional management of malnourished children, which was elaborated in the course of developing a setting-specific guideline for pediatric home care. Methods: The developed guideline is based on the approach described by the Scientific Medical Societies Working Group. This approach encompasses a) forming a group of experts, b) defining clinical questions, c) searching the literature, d) evaluating and synthesizing the literature, and d) formulating recommendations. Parents were included to rate the relevance of the recommendations. Results: The nutrition management involves a detailed nutritional assessment, subsequent oral, enteral or parenteral interventions, weight monitoring and a re-assessment of the child's nutritional status. Nurses, as well as parents/legal guardians, play essential roles in planning and implementing nutrition management in the home care setting. Conclusions: The use of the guideline may contribute to the early detection of causes for malnutrition and adequate multidisciplinary treatment of children with suspected or identified malnutrition in the home care setting.

An exclusive human milk diet for very low birth weight newborns-A cost-effectiveness and EVPI study for Germany

OBJECTIVES

Human milk-based fortifiers have shown a protective effect on major complications for very low birth weight newborns. The current study aimed to estimate the cost-effectiveness of an exclusive human milk diet (EHMD) compared to the current approach using cow's milk-based fortifiers in very low birth weight newborns.

METHODS

A decision tree model using the health states of necrotising enterocolitis (NEC), sepsis, NEC + sepsis and no complication was used to calculate the cost-effectiveness of an EHMD. For each health state, bronchopulmonary dysplasia (BPD), retinopathy of prematurity (RoP) and neurodevelopmental problems were included as possible complications; additionally, short-bowel syndrome (SBS) was included as a complication for surgical treatment of NEC. The model was stratified into birth weight categories. Costs for inpatient treatment and long-term consequences were considered from a third party payer perspective for the reference year 2017. Deterministic and probabilistic sensitivity analyses were performed, including a societal perspective, discounting rate and all input parameter-values.

RESULTS

In the base case, the EHMD was estimated to be cost-effective compared to the current nutrition for very low birth weight newborns with an incremental cost-effectiveness ratio (ICER) of €28,325 per Life-Year-Gained (LYG). From a societal perspective, the ICER is €27,494/LYG using a friction cost approach and €16,112/LYG using a human capital approach. Deterministic sensitivity analyses demonstrated that the estimate was robust against changes in the input parameters and probabilistic sensitivity analysis suggested that the probability EHMD was cost-effective at a threshold of €45,790/LYG was 94.8 percent.

CONCLUSION

Adopting EHMD as the standard approach to nutrition is a cost-effective intervention for very low birth weight newborns in Germany.

A porcine animal model to mimic the restart of enteral nutrition (refeeding-model)

With the aim towards establishing an animal model of total parenteral nutrition (TPN), 12 piglets aged 9 weeks (mean body weight 21 kg) were surgically provided with central venous catheters. Six piglets were nourished parenterally with the objective to reach a 14-d period of TPN; the other six piglets served as control and were fed normally. Only one animal from each group could be monitored over the whole period. Nine piglets were euthanised on d 13 and one on d 12. No animal showed fever or signs of septicaemia during the study. The levels of Ca, Mg, Na and P in the blood were within the normal range as were those for blood glucose and plasma creatinine. Symptoms of the TPN included: transient diarrhoea, occasional appearance of faecal blood and occasional absence of defecation. A reduced small intestine length and altered mucosal morphology and function were observed. One animal showed bile stasis at the end of the study. All TPN animals showed a remarkably high level of blood urea early in the morning. The intestinal symptoms observed may resemble the human situation during TPN. However, due to the fast growth rate, pigs aged 9 weeks have higher nutrient requirements per kg body weight. Consequently, the osmolality of the nutrient solution was necessarily high. Whether the significantly higher blood urea observed in the TPN group reflected a catabolic metabolism during the starving period at night-time could not be conclusively shown. Alternatively, it could reflect a slower growth rate and a resulting quantitative excess of amino acids (AA), or could have been the consequence of a suboptimal AA composition. A permanent infusion would be favourable in order not to overcharge the capacity for glucose uptake and amino acid metabolism during the infusion.

Incidence and Severity of Prescribing Errors in Parenteral Nutrition for Pediatric Inpatients at a Neonatal and Pediatric Intensive Care Unit

OBJECTIVES

Pediatric inpatients are particularly vulnerable to medication errors (MEs), especially in highly individualized preparations like parenteral nutrition (PN). Aside from prescribing via a computerized physician order entry system (CPOE), we evaluated the effect of cross-checking by a clinical pharmacist to prevent harm from PN order errors in a neonatal and pediatric intensive care unit (NICU/PICU).

METHODS

The incidence of prescribing errors in PN in a tertiary level NICU/PICU was surveyed prospectively between March 2012 and July 2013 (n = 3,012 orders). A pharmacist cross-checked all PN orders prior to preparation. Errors were assigned to seven different error-type categories. Three independent experts from different academic tertiary level NICUs judged the severity of each error according to the National Coordinating Council for Medication Error Reporting and Prevention (NCC MERP) Index (categories A-I).

RESULTS

The error rate was 3.9% for all 3,012 orders (118 prescribing errors in 111 orders). 77 (6.0%, 1,277 orders) errors occurred in the category concentration range, all concerning a relative overdose of calcium gluconate for peripheral infusion. The majority of all events (60%) were assigned to categories C and D (without major harmful consequences) while 28% could not be assigned due to missing majority decision. Potential harmful consequences requiring interventions (category E) could have occurred in 12% of assessments.

CONCLUSION

Next to systematic application of clinical guidelines and prescribing via CPOE, order review by a clinical pharmacist is still required to effectively reduce MEs and thus to prevent minor and major adverse drug events with the aim to enhance medication safety.
