Blended diets for tube-fed children and young people: a rapid review update

A study of professional practices, attitudes and barriers to blended tube feeding in Australia and New Zealand

AIMS

This study investigates the utilisation of blended tube feeding by health professionals in Australia and New Zealand, assessing factors influencing its implementation following the Australasian Society of Parenteral and Enteral Nutrition blended tube feeding consensus statement.

METHODS

A cross-sectional survey was conducted targeting health professionals across Australia and New Zealand. The survey comprised 35-questions including multiple choice, Likert scales and open-ended responses, to gain insights into blended tube feeding practices and perspectives. The effect of the health professional factors on outcomes was explored in pairs with a series of Chi-squared tests. Odds ratios (ORs) were calculated using standard univariate logistic regression. An exploratory content analysis was used to code the open-ended text responses to the survey questions which were then categorised and further synthesised into overarching themes.

RESULTS

Out of 89 health professionals who completed the survey, the majority were dietitians, 63% reported managing fewer than five patients using blended tube feeding within their services. Parental request was the leading reason for adoption. Notable barriers included clinician time constraints, resource limitations and a lack of formal guidelines. Some health professionals considered the primary risk associated with blended tube feeding to be poor growth and/or weight loss. Professional development was pivotal in increasing confidence and advocating for blended tube feeding, with significant correlations observed between blended tube feeding training and clinical practice.

CONCLUSIONS

This study emphasises the essential role of education, resource availability and institutional policy in promoting blended tube feeding practices for health professionals. Findings suggest that focusing on professional development and standardised resources could significantly enhance knowledge, confidence and competence of health professionals in blended tube feeding application. The outcomes point towards the need for a coordinated approach to support evidence-based blended tube feeding practices, aligning with the Australasian Society of Parenteral and Enteral Nutrition blended tube feeding resources and recommendations.

The effect of blended tube feeding compared to conventional formula on clinical outcomes in adults: A systematic review

AIM

To explore the effect of blended tube feeding compared to conventional formulas on nutritional status, quality of life, anthropometry, diarrhoea and tube blockages in adults receiving tube feeding.

METHODS

The protocol was registered (PROSPERO CRD42022372443). Five databases (MEDLINE, EMBASE, CINAHL, Scopus, CENTRAL) were searched from commencement of database to 14th June 2023 to identify studies comparing blended tube feeding to conventional formulas in adults receiving tube feeding. Certainty assessment was conducted using the Cochrane Risk of Bias Tools and the Grading of Recommendations, Assessment, Development and Evaluations framework, and a narrative synthesis of results is provided.

RESULTS

From 4227 studies screened, eight were included (total n = 763 patients, 9-215 patients). Three studies were hospital-based and five were home-based with duration from 8 days-8 months. Blended tube feeding and conventional formulas were nutritionally equivalent in only three studies; energy and protein concentration of formulas ranged from 1.7-7.1 kJ/mL and 21-68.5 g/L for the blended tube feeding groups, and 4.2-6.7 kJ/mL and 39-100 g/L for the conventional groups. No studies assessed nutrition status or quality of life using validated measures. Blended tube feeding was associated with a clinically relevant reduction in diarrhoea with a low level of certainty. For remaining outcomes, there were inconclusive findings and an overall very low certainty of evidence for each.

CONCLUSION

The effect of blended tube feeding compared to conventional formulas on all outcomes remains uncertain. Blended tube feeding may reduce the incidence of diarrhoea. Future research using nutritionally equivalent comparisons and validated outcome measures is required.

Blended diets for children and young people: applying the evidence to nursing practice

Enteral tube feeding is commonly used for children and young people with complex health and care needs. Blended diets are becoming more widely used and there is increasing evidence to show the benefits of a blended diet for children, young people and their families. This article aims to collate recent evidence on blended diets and describe the implications for nursing practice. Studies exploring blended diets have identified benefits such as improved gastrointestinal symptoms, positive engagement with families around food and mealtimes and the normalisation of enteral tube feeding. Research has also explored the nutritional and microbial content of food blends as well as the viscosity and risk of tube blockage. These are key considerations when supporting families to make informed decisions and use blended diets safely. Nurses play an important role in supporting the safe and effective use of blended diets as part of a wider multidisciplinary team. It is necessary that they have an understanding of the evidence underpinning nursing practice in this area.

An exploration of the experiences and attitudes of healthcare professionals towards enteral tube feeding for adults living in the community following stroke

BACKGROUND

Guidelines recommend enteral feeding via gastrostomy should be considered for adult survivors of stroke with dysphagia who cannot eat or drink sufficiently for >4 weeks. Many people continue long-term tube-feeding via this route in the community where healthcare professionals contribute to their care and nutritional management, although little is known about their experiences of or attitudes towards enteral feeding in this situation. The present study aimed to explore the experiences and attitudes of healthcare professionals working with this patient group.

METHODS

Healthcare professionals were invited to complete a questionnaire devised for the study which comprised closed and open questions about tube-feeding including their patients' participation in feeding processes and mealtimes and how these might be improved. Responses to closed questions were analysed descriptively and free-text responses analysed using thematic analysis.

RESULTS

Fifty-seven participants met the inclusion criteria. They identified patients' quality of life (77% of respondents) and nutritional support (75%) as the most important aspects of tube-feeding. Good communication and training with healthcare teams and carers were considered important. Their patients' participation in tube-feed administration and mealtime involvement were described as variable and potentially beneficial, but both were related to patients' choice and health impairment. Blended tube-feeding was considered an option by 89% provided practical and safety conditions were met.

CONCLUSIONS

Participants' experiences of and attitudes towards tube feeding in adults living with stroke in the community in the sample in the present study are varied and focussed on individual patients' needs, safety and professional standards.
