Blended diet in enteral feeding: current guidance.

The practice of administering blended food via enteral feeding tubes has been growing in popularity in recent years. Concerns have been raised as this practice was perceived to increase risk of gastrointestinal intolerance, allergic reactions, nutritional insufficiency, tube blockages, and infection compared with using commercial enteral feed (CEF), the gold standard, as well as risk of litigation against the professional due to their support of practice that is not evidence-based. However, research has shown that the physical, social and emotional benefits from receiving blended diet may outweigh the previously suggested risks. Guidance has been updated to encourage discussions around blended diet while informing the tube-fed individuals, families and carers of potential risks, potential benefits, barriers, considerations for training, safety and contraindications.

A systematic review examining the impact of blended diets on the gastrointestinal symptoms of people who are enterally fed.

BACKGROUND: Adults and children who are enterally tube-fed can experience adverse gastrointestinal symptoms (GIS). Observational data suggests that blended diets (BD) could mitigate such symptoms, with potential to improve quality of life and clinical outcomes. We present a novel systematic review examining the impact of BD, compared to commercial feeds, on GIS of adults and children who are tube-fed. METHODS: The protocol was registered with PROSPERO (CRD42021261147). Four electronic databases were searched from inception to August 2021. Search terms included 'tube-fed', 'blended diet' and 'formula'. Inclusion criteria were intervention studies comparing blended and commercial feeds using quantitative measures of GIS. Heterogeneity of outcome measures precluded meta-analysis; therefore, a narrative synthesis was conducted. RESULTS: Six papers (n = 219), including two randomised control trials (RCT) and four single arm pre-post studies, were identified. Equal numbers studied in- and out-patients, adults and children. Risk of bias was notable for all studies. Equivocal and insufficient evidence prevented consensus on outcomes of vomiting, gagging, oral intake, bloating and constipation. However, one RCT and two single arm pre-post studies suggest that diarrhoea symptoms may be improved on BD. CONCLUSIONS: Diarrhoea is prevalent in tube-fed populations and associated with adverse outcomes. Improvements in diarrhoea symptoms attributed to BD may be clinically important. Our findings are congruous with the wider observational evidence base, and support recommendations of the British Dietetic Association. BD may pose a viable alternative to commercial formula, and may mitigate symptoms of diarrhoea for adults and children who are tube-fed.

Blended diet for enteral tube feeding in young people: A systematic review of the benefits and complications.

BACKGROUND: Interest and use of blended diets (BD) for young people who are tube fed has significantly increased in the last decade, driven primarily by the desires of motivated caregivers. This review identified, appraised and synthesised the available evidence on the benefits and complications of BD versus commercial feeds. METHODS: A systematic review following PRISMA guidance and registered with PROSPERO was conducted across PubMed, Embase, CINAHL, Scopus and Cochrane up to August 2022. INCLUSION CRITERIA: English language studies including (1) children, (2) original research (interventional and observational) and (3) examination of BD outcomes. Exclusion criteria were (1) unoriginal research or case reports, (2) focus on feeding management, preparations or attitudes and (3) comparing commercial blends only. Data were synthesised using an established narrative synthesis approach using the Mixed Methods Appraisal Tool. RESULTS: Eight hundred and six database results were identified and 61 were sought for retrieval. A full-text article review revealed seven eligible studies, involving 267 participants (age range 9 months to 26 years). Studies reported differences in gastrointestinal symptoms (n = 222), medication use (n = 119), growth (n = 189) and complications or adverse events (n = 91). The results indicate positive outcomes, particularly in gastrointestinal symptom control, with few reports of mild adverse events in the included studies. CONCLUSIONS: There is a paucity of data in this area and much heterogeneity in the included studies, but the available literature points towards positive outcomes. This is an important and highly relevant topic, and more primary research, ideally using standardised reporting, is required to answer the key questions.

Introduction of blended diet for enteral tube feeding in paediatrics: A case report.

Background: Advances in medical technology have resulted in changes to enteral tube feeding (ETF). Standard practice in the UK is to use commercial formula for ETF via the stomach or small intestine; however, blended diets are becoming increasingly popular. Emerging evidence shows benefits of a blended diet although evidence informing clinical guidance is sparse. Consequently, there is disparity in practice, and it remains unclear which patient groups may benefit most from a blended diet. Aim: To demonstrate the initiation of a blended diet in clinical practice. Methods: This case report features a 2-year-old child requiring ETF in the context of hypotonia, developmental delay and faltering growth. Results: In this instance, a blended diet resulted in improved gastrointestinal symptoms and adequate growth. Conclusion: This case demonstrates the successful implementation of a blended diet and associated benefits. Blended diets may benefit others requiring ETF and should be considered on an individualised basis.

A multidisciplinary approach to providing blended diet within the acute setting.

BACKGROUND: Due to advances in medical care, including nutrition and hydration, children with neurological impairment are surviving longer. Many of these children are fed using a commercial formula via an enteral feeding tube. However, families are now becoming more interested in administering blended diet via their child's gastrostomy in a bid to reduce often significant gastrointestinal symptoms including reflux, constipation, gagging and retching post fundoplication. AIMS: To describe the process undertaken by the authors' short-life working group to create safe, robust pathways to enable children to have access to blended diet while in the acute hospital setting. METHODS: A multidisciplinary team short-life working group was established, which consisted of representatives from nursing, dietetics and catering. Following this a scoping exercise was undertaken to assess what practices were carried out in other health boards, prior to the creation of documentation. CONCLUSION: In conjunction with senior management and the Central Legal Office, the authors' short life working group has created safe, robust documentation and pathways to enable children in a large tertiary paediatric centre to access blended diet while in the acute setting. Due to the recent COVID-19 pandemic the pilot study to trial these documents within the neurology ward was delayed, however this work is ongoing. Furthermore, the authors will be looking to train nursing staff within ward areas to administer blended diet within the ward setting.

The parental experience and perceptions of blenderized tube feeding for children with medical complexity.

OBJECTIVES: Parents of children with medical complexity are often expected to implement complicated plans of care, such as enteral tube feeding, to support the health of their child. Enteral feeding can have psychosocial implications for the parent, child, and family. Blenderized tube feeding (BTF) refers to the administration of pureed food and drinks through a feeding tube. Little is known regarding parents' experiences with BTF. Therefore, the purpose of this qualitative study was to understand the lived experience of BTF from the parent's perspective. METHODS: This qualitative study was a grounded theory analysis utilizing semi-structured interviews of parents who provided at least 50% of their child's diet through BTF. Participants were recruited using purposive sampling from the Complex Care Program at a tertiary care paediatric centre. Interviews were conducted until thematic saturation was achieved. Themes were identified using constant comparative analysis of transcribed interviews. RESULTS: Parents (n=10) felt that BTF positively affected the experience of tube feeding and enhanced their child's health and wellbeing. Parents described BTF as a means of self-empowerment and a mechanism to normalize feeding and care for the entire family. Despite reporting BTF as more time consuming than formula feeding, all parents were satisfied with having made the change, and planned on continuing the diet. CONCLUSION: BTFs can improve the experience of tube feeding and positively address some of the negative psychosocial implications of enteral tube feeding, providing a sense of normalcy and control for parents caring for a child with medical complexity.

Patient and carer experience of blended diet via gastrostomy: a qualitative study.

BACKGROUND: Home enteral feeding is becoming increasingly prevalent within the UK. The use of commercial prescription formula is considered best practice; however, increasingly, patients are choosing to use blended diet via gastrostomy. There is anecdotal evidence suggesting both physical and social benefits, although there are concerns regarding the safety and efficacy of this method of feeding. The present study explores the experiences of patients who are currently using or have used this method of feeding in the past. METHODS: Patients currently using or having previously used blended diet via gastrostomy were identified. Patients and their carers, where applicable, were invited to participate in a semi-structured interview. The data were transcribed and themes were identified. RESULTS: Thematic analysis of the data collected showed that patients had an overall positive experience of blended diet with few or no identified disadvantages. Participants reported improvements in gastrointestinal symptoms, as well as general wellbeing, in addition to the social benefits of their family member being included in family mealtimes. Reference was made to the lack of support for this method of feeding and the desire for blended diet to be offered as an alternative to commercial enteral feed. CONCLUSIONS: This research highlights the benefits of blended diet via gastrostomy as an alternative to commercial formula. More research is needed to develop evidence-based guidelines for patients and the healthcare professionals supporting them.

Blended diets for gastrostomy fed children and young people: a scoping review.

BACKGROUND: The present review aimed to identify what is known about the use of blended diets in gastrostomy fed children and young people (i.e. children and young people refers to those who are aged up to 25 years with special educational needs or a disability in accordance with Part 3 of the Children and Family Act 2014; within the review, the word children is used for simplicity but encompasses young people too) and to identify gaps in the literature on this topic to inform future research and policy. METHODS: A scoping review methodology was used searching the online databases PUBMED, PsychINFO, CINAHL, SCOPUS and AMED, EMBASE for articles that addressed issues pertaining to blended diets. The review identified a broad range of literature, regardless of study design, and described and evaluated the quality, range and nature of research activity related to the use of blenderised diets. RESULTS: Forty-three studies were included in the review. The studies focused on nutrition, equipment, the views of carers and patients, and the views of professionals. Several studies described the lack of evidence regarding pros and cons of blended diets and highlighted the need for further research into the field. CONCLUSIONS: There were gaps in the evidence base regarding the impact of blended diets on the health and well-being of the children who receive them and upon the carers who feed the children. The nutritional impact of blended diets is not fully understood and the knowledge and views of professionals involved in the care of those receiving blended diets varies.

Determinants in parents' decision to use blended diets with gastrostomy-fed children and young people: A mixed methods study.

BACKGROUND: Children fed via a gastrostomy are provided with commercial produced formula feeds. They are not offered blended diet (BD) as an alternative, and it is not formally supported in the UK due to concerns regarding nutritional content, contamination and tube blockages. Despite this increasing numbers of families are opting to use BD. OBJECTIVE: To discover why parents opt to use of BD with their children and young people who are fed via gastrostomy. METHOD: This mixed methods study comprised a qualitative phase of 18 in-depth interviews with parents who were using BD with their child. The quantitative phase comprised a survey of 208 parents, 140 of whom used BD and 68 did not use BD. RESULTS: The in-depth interviews identified four overarching themes that influenced parents' decision to use BD; loss, conflict, empowerment and quality of life. Responses from the survey revealed differences between those who did and did not use BD in levels of self-efficacy, views about formula feeds, rating of their child's health and stools. CONCLUSION: Concerns about formula feeds and less perceived need for it are key determiners in parents' decision to use BD. These views are influenced by social constructs and individual beliefs and circumstances. Those using BD were more likely to rate their child's stools as being normal and rated their child's health more highly than those not using BD.

An observational investigation of the faical microbiota and metabonome of gastrostomy fed children, on blended and formula diets.

Gastrostomy fed children traditionally have a Formulae diet (FD), which fulfills nutritional requirements; however, many families are adopting Blended diets (BD), which are what the whole family would eat. We undertook an observational investigation of the colonic microbiota and metabonome in a small group of gastrostomy fed children, who were either on an FD or BD, and compared, where possible to their siblings (17 FD, 28 BD, 19 HS). There was no increase in complications in tube blockage or infection rates, but a significant improvement in the prevalence of bowel problems, a reduction in medication and an increase in quality of life. Metataxonomic analysis showed that the FD group was significantly different to the Sibling group, and that families did not cluster together. Whole sample metabonomics showed no differences between groups; however, univariate analysis of biologically important metabolites did differ. Changing to a BD resulted in no increase in complications or risks, but improved the overall quality of life for the children and families.

Monitor gastrointestinal tolerance in children who have switched to an "enteral formula with food-derived ingredients": A national, multicenter retrospective chart review (RICIMIX study).

BACKGROUND: Enteral tube feeding intolerances, such as diarrhea, are commonly reported in children. In the pediatric population, interest is growing in the use of blended diets for the management of enteral feeding intolerances. Fiber within a blended diet stimulates the growth of beneficial gut bacteria, which in turn produce short-chain fatty acids, which are utilized as energy substrates for enterocytes. Enteral formula manufacturers have responded to this trend towards "real-food" blended diets and developed an enteral formula with food-derived ingredients. The aim of this study was to collect data relating to feed tolerance in children who had switched to an "enteral formula with food-derived ingredients." METHODS: A national multicenter retrospective study. RESULTS: Dietitians collected data from 43 medically unwell children between March 2021 and July 2021. Significant improvements were reported in children who had switched to an "enteral formula with food-derived ingredients" in retching 17 of 18 children (95%), flatulence 6 of 8 children (85%), loose stools 10 of 11 children (90%), and constipation 10 of 11 children (90%). These improvements in gastrointestinal symptoms were reflected in weight change during the one month period measurements were collected (baseline, 19.5 kg [SD, 9]; 1 month, 20.1 kg [SD, 9]; P = 0.002). CONCLUSION: We have observed beneficial outcomes in medically complex children who have switched to an "enteral formula with food-derived ingredients." Our data should motivate healthcare professionals to implement more research to better evaluate the clinical impact and mechanisms of action of blended diets and enteral formulas with food-derived ingredients.

Nutritional Feeding Strategies in Pediatric Intestinal Failure.

Intestinal failure is defined as a critical reduction of the gut mass or function, below the minimum needed to absorb nutrients and fluids. The ultimate goal in intestinal failure is to promote bowel adaptation and reach enteral autonomy while a healthy growth and development is maintained. The condition is heterogeneous and complex. Therefore, recommendations for the type and duration of parenteral, enteral, and oral nutrition are variable, with the child's age as an additional key factor. The aim of this review is to provide an overview of nutritional feeding strategies in this heterogeneous population. Different perspectives on nutritional management, nutrition and adaptation, and microbiome and nutrition will be discussed.

Efficacy and Tolerance of Blended Diets in Children Receiving Gastrostomy Feeds.

BACKGROUND: To determine the prevalence of gastrointestinal (GI) symptoms in children receiving a blended diet via a gastrostomy tube. METHODS: This is a single-center, retrospective study of children ages 1-18 years that received a blended diet. We reviewed demographics, anthropometrics, clinical characteristics, and rationale for switching to blended diet. Fixed-effects logistic regression analysis was used to evaluate the changes in patient symptoms over the 12-month follow-up period, and fixed-effects regression was employed to test for changes in anthropometrics. RESULTS: Twenty-three patients (8 female, 15 male) were identified, and data from 89 outpatient visits were analyzed. The most common underlying diagnosis was neurological disorder. Thirty-five percent of patients received commercial whole cow milk formulas, 30% received hydrolysate formulas, and 35% received amino acid-based formulas. After formula switches were made, 65% received homemade blended diets, 17.5% received commercial blended diets, and 17.5% received a combination of both. Median duration of time on a blended diet was 17 months. Ninety-five percent of patients who were previously experiencing upper GI symptoms improved within the first 3 months after blended diet initiation. Twenty-one percent of patients developed mild constipation on the diet, which was managed with increased water intake and/or polyethylene glycol. Only 2 patients discontinued the blended diet, because of inadequate weight gain and worsening of upper GI symptoms. CONCLUSIONS: In our study population, blended diets were well tolerated in gastrostomy-fed children and were associated with clinical improvement of upper GI symptoms.

Blended foods for tube-fed children: a safe and realistic option? A rapid review of the evidence.

With the growing number of children and young people with complex care needs or life-limiting conditions, alternative routes for nutrition have been established (such as gastrostomy feeding). The conditions of children and young people who require such feeding are diverse but could relate to problems with swallowing (dysphagia), digestive disorders or neurological/muscular disorders. However, the use of a blended diet as an alternative to prescribed formula feeds for children fed via a gastrostomy is a contentious issue for clinicians and researchers. From a rapid review of the literature, we identify that current evidence falls into three categories: (1) those who feel that the use of a blended diet is unsafe and substandard; (2) those who see benefits of such a diet as an alternative in particular circumstances (eg, to reduce constipation) and (3) those who see merit in the blended diet but are cautious to proclaim potential benefits due to the lack of clinical research. There may be some benefits to using blended diets, although concerns around safety, nutrition and practical issues remain.

Multi-agency practice for developing a blended diet for children fed via gastrostomy.

The administration of a blended diet via a gastrostomy tube to children with complex needs is an evolving area of practice. Healthcare professionals must provide guidance, promote best practice and optimise patient safety where patients and families choose a blended diet in preference to the prescribed commercial feed. The Aneurin Bevan Health University Health Board in Newport, Wales, took a collaborative approach, by working with parents as equal partners, to enable a child with complex needs to receive a blended diet at school. The development of a protocol and risk-assessed approach enabled the delivery of bespoke flexible care that met the holistic needs of the child and family and improved the child's quality of life. The initiative also led to positive outcomes for the school and wider community.
