Blended tube feeding prevalence, efficacy, and safety: What does the literature say?

The Effect of Hospital-Based Liquid Diet and Commercial Formulas on Laboratory Parameters and Postoperative Complications in Patients with Head and Neck Cancer

Background: Patients with head and neck cancer (HNC) are at high risk of malnutrition. The aim of this study was to compare the effect of polymeric formulas available commercially and a high-protein liquid diet prepared in the hospital on laboratory parameters and postoperative complications in patients undergoing surgery for HNC. Methods: This single-center retrospective study included 149 patients who underwent surgery for HNC between 2008 and 2017. The following data were collected: patient and tumor characteristics, postoperative complications, and laboratory parameters measured at baseline and after surgery, including creatinine, alanine transaminase (ALT), aspartate transaminase (AST), and blood glucose levels. Correlations between the duration of enteral nutrition and blood parameters were assessed. Results: After surgery, patients receiving commercial formulas had lower creatinine and blood glucose levels and higher ALT and ASP levels than those on the hospital-based diet. The longer duration of feeding with commercial formulas before surgery was associated with enhanced preoperative levels of ALT and ASP and with lower postoperative blood glucose. Patients on the hospital-based diet had a higher rate of postoperative complications than those receiving commercial formulas (16.1% vs. 3.3%). Conclusions: There were no clinically important differences in blood parameters among patients with HNC depending on the type of preparations used for enteral feeding. However, increased levels of liver enzymes in patients fed with commercial formulas were notable. The early initiation of enteral nutrition before surgery helped achieve normal blood glucose levels after surgery. The use of commercial preparations contributed to reducing the number and incidence of postoperative complications.

Blenderized food tube feeding in very young pediatric patients with special healthcare needs

BACKGROUND

Up to 85% of children with severe developmental disabilities have feeding disorders and require enteral tube feeding. Many caregivers desire blenderized tube feeding (BTF) instead of commercial formula (CF) for their child, citing a desire for a more physiologic feeding, to reduce gastrointestinal (GI) symptoms and/or promote oral intake.

METHODS

In this retrospective, single-center study, medical records (n = 34) of very young children (aged ≤36 months) with severe developmental disabilities were reviewed. Comparisons of growth parameters, GI symptoms, oral feeding, and GI medication use were made between the initial introduction of BTF and again at the last patient encounter when the children aged out of the program.

RESULTS

Of the 34 charts reviewed (16 male and 18 female patients), comparisons between baseline BTF introduction and the last patient encounter indicated reductions in adverse GI symptoms, significant GI medication reduction (P = 0.000), increased oral food intake, and nonsignificant improvements in growth parameters. These positive outcomes were realized whether children received full or partial BTF or type of BTF formulation.

CONCLUSION

Consistent with similar research studies, transitioning very young children with significant special healthcare needs from CF to BTF resulted in improvement in GI symptoms, reduced need for GI medications, supported growth goals, and contributed to improved oral feeding.

Experiences and perceptions of multidisciplinary paediatric teams of blended tube feeding in children

Background: Blended tube feeding (BTF) is the administration of pureed whole foods via gastric feeding tubes. There is some evidence to suggest that BTF may have clinical and psychosocial benefits when compared to commercial formula, but further investigation of how BTF is understood and recommended by health professionals is needed. This study aims to investigate awareness and knowledge of BTF among multi-disciplinary paediatric staff in Ireland. Methods: A cross-sectional observational study was conducted among paediatric staff in Children's Health Ireland (CHI). The 16-item anonymous online survey gathered information on awareness of BTF, willingness to recommend BTF, confidence in BTF knowledge, and self-assessed competence in managing BTF. Results: Of the 207 responses, doctors (n68), nurses (n66), and dietitians (n32) provided 80.3% of responses. Two-thirds (n136, 66%) of the total group were aware of BTF. Of these, 68.1% had cared for a child on BTF and 70% (n = 63/90) were willing to recommend BTF. Three in five (n = 39/63, 61.9%) stated they were somewhat confident in their BTF knowledge and one in five (n = 12/56, 21.4%) were not yet competent in managing children on BTF. The most common reasons for recommending BTF were parental desire (n17, 39.5%) and commercial formula intolerance (n15, 34.9%). The most common barrier to recommending BTF was family logistics (n18, 41.9%). The most valuable sources of information on BTF for two-thirds (68.3%) of participants were other healthcare professionals (HCPs) and patients/caregivers. Conclusion: Healthcare settings should provide evidence-based training to HCPs on BTF to optimise the treatment and safety of children under their care.

Blenderized tube feedings: Practice recommendations from the American Society for Parenteral and Enteral Nutrition

Prior to the 1970s, blending food and liquids and putting them through an enteral access device (EAD) was the most common form of enteral nutrition (EN). However, in the 1970s, blenderized tube feedings (BTFs) became less popular due to the emergence of modern commercial enteral formulas (CEFs). Recently, a cultural shift toward consuming a natural diet, consisting of whole foods, has led to a resurgence in the use of BTF. The increasing use of BTF in a variety of patient care settings identifies a need for practice recommendations that provide guidance for nutrition professionals and patients. Members of the American Society for Parental and Enteral Nutrition (ASPEN) Enteral Nutrition Committee identified salient clinical questions concerning BTF, conducted a comprehensive literature search, and subsequently developed practice recommendations pertaining to the use of BTF. This paper was approved by the ASPEN 2022-2023 Board of Directors.

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.

Blenderised Tube Feeds vs. Commercial Formula: Which Is Better for Gastrostomy-Fed Children?

Blenderised tube feeds (BTF) have become a popular alternative to commercial formula (CF) for enterally fed children. This study sought to compare gastrointestinal (GI) symptoms, GI inflammation, and stool microbiome composition between children receiving BTF or CF. This prospective cohort study involved 41 gastrostomy-fed children, aged 2–18 years, receiving either BTF (n = 21) or CF (n = 20). The Paediatric Quality of Life Inventory Gastrointestinal Symptoms Scale (GI-PedsQL) was used to compare GI symptoms between the groups. Anthropometric data, nutritional intake, nutritional blood markers, faecal calprotectin levels, stool microbiota, and parental satisfaction with feeding regimen were also assessed. Caregivers of children on BTF reported greater GI-PedsQL scores indicating significantly fewer GI symptoms (74.7 vs. 50.125, p = 0.004). Faecal calprotectin levels were significantly lower for children receiving BTF compared to children on CF (33.3 mg/kg vs. 72.3 mg/kg, p = 0.043) and the BTF group had healthier, more diverse gut microbiota. Subgroup analysis found that 25% of caloric intake from BTF was sufficient to improve GI symptoms. The CF group had better body mass index (BMI) z-scores (−0.7 vs. 0.5, p = 0.040). Although growth was poorer in children receiving only BTF in comparison to the CF group, this was not seen in children receiving partial BTF. A combination of BTF and CF use may minimise symptoms of tube feeding whilst supporting growth.

MICROBIOLOGICAL QUALITY OF ENTERAL FORMULATIONS HANDLED AT HOME: A SYSTEMATIC REVIEW

BACKGROUND

Studies have shown an increase in the number of patients who use enteral nutrition at home, and the benefits of this type of nutritional care. However, little is known about the risk of bacterial contamination of enteral formulations prepared at home. Therefore, the aim of the study was to assess the microbiological quality of home-prepared enteral formulations.

METHODS

This study is a systematic review, registered in PROSPERO. The search for articles was carried out in databases and gray literature. Eligible studies which microbiologically analyzed homemade enteral preparations (HEP), blended enteral preparations (BEP), and commercial enteral formulas (CEF) that were prepared at home were selected. The types and quantities of microorganisms, sources of contamination in the handling area, and the consequences of contamination (signs and symptoms) were the subjects extracted from the studies.

RESULTS

Five studies evaluated 217 enteral formulations. It was found that 72.81% of the enteral formulations exceeded the acceptable bacterial count in the case of at least one of the analyzed microorganisms. This result corresponded to 93.58% (n=73) of the HEP; 81.96% (n=50) of the BEP; and 44.87% (n=35) of the CEF. The presence of ten different microorganisms was identified in the enteral formulations, and total coliforms and mesophilic aerobics were the microorganisms found in the greatest quantity in the samples.

CONCLUSION

The three types of home-prepared enteral formulations showed unsatisfactory microbiological quality, indicating poor hygiene conditions during food handling. This article is protected by copyright. All rights reserved.

Low risk for microbial contamination of syringe and tube feeding bag surfaces after multiple reuses with home blenderized tube feeding

BACKGROUND

Guidelines for the reuse of enteral tube feeding (ETF) equipment guidelines are limited to manufacturer recommendations. ETF equipment reuse studies are needed as the enteral population has increased, along with blenderized tube feeding (BTF).

METHODS

This experiment tested microbial contamination of a reusable gravity feeding bag and syringe after 15 BTF reuses and cleanings. Eight bags and syringes were filled with the BTF, held at room temperature for 20 min, and then emptied, washed, and air dried. After the last air drying, the inner surfaces of the bag and syringe were swabbed, and aerobic microbial counts were performed using serial dilutions and plate counts.

RESULTS

The microbial counts for all syringes and six bags were <1 colony-forming unit (CFU)/cm² ; one bag was <5 CFU/cm² and one bag was 12.5 CFU/cm² . No legal guidelines for surface cleanliness exist for the food sector. Several studies propose a safe microbial level to be <2.5 CFU/cm² , and the European Commission recommended <10 CFU/cm² . Based on these proposed guidelines, microbial counts of all syringes and seven bags were within the proposed guidelines, except for one bag just above 10 CFU/cm² .

CONCLUSION

The feeding bag used in this study may be used multiple times for BTF with a reduced risk of microbial contamination when manufacturer's cleaning guidelines are followed. Although bolus tube feeding is an off-label use for syringes, they are frequently used for BTF, and in this study the cleaning after 15 uses over 5 days was effective to reduce microbial counts.

Blenderized tube feeding for children: an integrative review

OBJECTIVE

To analyze scientific evidence on the use of blenderized tube feeding in children regarding nutritional composition, family satisfaction, and health outcomes.

DATA SOURCE

Survey was conducted in the PubMed, Scopus, Embase, and Virtual Health Library (VHL) databases using the following search terms: blenderized tube feeding OR blended tube feeding OR homemade OR pureed AND enteral nutrition AND enteral tube. The methodological quality of the selected articles was evaluated using the Critical Appraisal Skill Programme and Hierarchical Classification of Evidence.

DATA SYNTHESIS

After analysis, 11 articles were included in the present review. Most studies demonstrated improvements in health outcomes and greater family satisfaction after replacing the commercial enteral feeding with blenderized tube feeding.

CONCLUSIONS

When guided and monitored by the healthcare team, a blenderized tube feeding ensures an adequate nutritional composition. The use of this method is also associated with positive health outcomes such as reductions in gastrointestinal symptoms and hospitalizations. Moreover, a high frequency of family satisfaction was verified.

Blenderized food tube feeding in patients with head and neck cancer

Background

Patients with headand neck cancer (HNC) are at high risk for malnutrition before and during chemoradiation treatment. Many will also require tube feeding to address declines in energy intake, weight, and quality of life (QOL) caused by the impact of treatment on gastrointestinal (GI) symptoms. Blenderized tube feeding (BTF) may ameliorate these adverse conditions.

Methods

In this open‐label, prospective pilot study, 30 patients with HNC who required feeding tube placement were recruited to switch from standard commercial formula after 2 weeks to a commercially prepared BTF formula. Weight, body mass index (BMI), GI symptoms, and QOL scores were tracked for 6 weeks from the first week of feeding tube placement.

Results

Of the 16 patients who completed the 6‐week assessment period, weights and BMI scores for 15 patients trended upward. For most patients, QOL and oral intake increased and GI symptoms decreased over the 6‐week period, particularly during weeks 3 and 4, when the impact of treatment is particularly exacting on patients with HNC.

Conclusion

BTF effectively mitigated weight loss, GI symptoms, QOL scores, and total energy intake in this group of patients with HNC who received tube feeding for 6 weeks.

Parents and health professionals' experiences and perceptions of blended feeding in tube-fed children: a qualitative systematic review protocol

OBJECTIVE

The objective of this review is to identify and synthesize the best available evidence on parents' and health professionals' experiences and perceptions of blended feeding in tube-fed children in order to promote effective decision-making on its use.

INTRODUCTION

Blended feeding is not a new concept, despite the fact that commercial formulas have displaced its use in recent years. As feeding is viewed as an intimate experience between a parent and child, the choice of individualized blended feeds is something to be considered; however, professionals find there is a lack of evidence and discussion to support the use of blended feeding in practice. Therefore, the findings of this review may be beneficial, especially for professionals, and inform or promote more effective decision-making on the use of blended feeding.

INCLUSION CRITERIA

This review will consider studies that investigate parents and/or health professionals' experiences and perceptions of total or partial blended feeding in tube-fed children. Studies published in English that focus on qualitative data will be considered. There will be no restrictions on year or publication.

METHODS

The key information sources to be searched are: CINAHL Complete, MEDLINE, PsycINFO, Embase, Web of Science, WHO Library Database (GIM), and Google Scholar, along with several sources of gray literature. Two reviewers will independently screen titles and abstracts against the inclusion criteria, and will retrieve full text studies, assess methodological quality, and extract data. Findings will be pooled using meta aggregation, and a ConQual Summary of Findings will be presented.

Exploring Clinical Outcomes and Feasibility of Blended Tube Feeds in Children

Commercially produced complete nutritional formulas (CFs) are commonly delivered to children requiring enteral nutrition via gastrostomy. However, a cultural shift toward consuming a more natural diet consisting of whole foods has caused the use of blenderized tube feeds (BTFs) to grow in popularity among parents and carers in recent years. There are advantages and disadvantages of both BTF and CF use. There is evidence that suggests that BTFs can significantly improve tube-feeding tolerance and reduce gastrointestinal symptoms associated with tube feeding, such as gagging, retching, and constipation, thereby resulting in an improved quality of life (QoL) for enterally fed children and their caregivers. BTFs have also been implicated in increasing the diversity of the gut microbiota in enterally fed children. However, concerns have been raised that BTFs may be inferior to CFs in energy and nutrition sufficiency. Issues such as microbial contamination, tube blockages, and difficulties in preparation and administration may also complicate the use of BTFs. Additionally, like CFs, BTFs can vary significantly in nutrition composition, and dietitian involvement with BTF use is crucial. The current literature on the clinical outcomes of BTF use is limited, and further research is needed before recommendations can be made on BTF use in children. A literature review was conducted to compare clinical outcomes between BTFs and CFs and evaluate the feasibility of BTF use in children.

Attitudes and Perceptions of Blenderized Tube Feed Use Among Physicians and Advanced Practice Providers

BACKGROUND

Blenderized tube feeds (BTFs) have increased in popularity among enteral patients and their caregivers as an alternative to commercial formula. Motivations include ingredient flexibility, increased tolerance, and inclusion in family meals. Research has explored the attitudes and perceptions of patients, caregivers, and registered dietitian nutritionists but not those of physicians and advanced practice providers (APPs). The purpose of this study was to evaluate their attitudes and perceptions of BTFs.

METHODS

A survey created via Research Electronic Data Capture tools was distributed to physicians and APPs to evaluate clinical practice characteristics, experience, knowledge, and perceptions of BTFs.

RESULTS

Survey response rate was 17.3% (n = 206). Half of respondents reported familiarity with BTFs, but 95% of respondents had received no formal training regarding BTFs. Physicians reported higher levels of confidence in BTF knowledge than APPs. However, the overall level of confidence in BTF knowledge was poor, with a majority of respondents (73.3% [n = 151]) reporting either "not very confident" or "not confident at all." The most perceived benefits included tailoring diet to better fit the patients' needs (70.9% [146]) and psychological benefits (59.2% [122]). Barriers that most concerned respondents included tube occlusions (59.7% [123]) and nutrition inadequacy (47.6% [98]). χ² Analysis revealed no relationship between type of provider and perceived benefits or barriers.

CONCLUSION

A majority of physicians and APPs are willing to support BTF use but lack education or guidance, resulting in poor confidence. Increased familiarity with BTF use and awareness of available education materials are required to help physicians and APPs support patients utilizing BTFs.

The Microbial Quality and Safety of Blenderised Enteral Nutrition Formula: A Systematic Review

The use of blenderised enteral nutrition formula (ENF) is on the increase globally. However, concerns remain regarding the microbial quality and safety of blenderised ENF compared with standard recommendations and commercial ENF.

AIM

This was a systematic review which sought to compare the microbial quality of blenderised ENF and commercial ENF and to evaluate the effect of storage time on blenderised ENF.

METHOD

Four databases (Pubmed, EMBASE, PSYCInfo and Google scholar) were searched for relevant articles based on the Population, Intervention, Comparator, Outcomes framework.

RESULTS

Eleven studies which met the criteria were included in the systematic review. Two major areas were identified; Microbial Quality of Blenderised ENF versus Commercial ENF; and The Effect of Storage Time on Microbial Quality of Blenderised ENF. Overall, 72.7% of the studies showed microbial contamination in blenderised ENF compared with 57.1% of commercial ENF, and the storage time was another important factor in the rates of contamination. The extent of handling or manipulation of the enteral formula was critical in determining the level of contamination.

CONCLUSION

Preparation techniques for blenderised ENF need to be established and caregivers taught how to prepare and administer it appropriately in order to reduce contamination. Further, well-designed studies are required, which compare the microbial quality of blenderised ENF using adequate handling techniques and commercial ENF.

Home-Prepared Enteral Tube Feeding: Evaluation of Microbiological Contamination, Hygiene, and the Profile of the Food Handler

BACKGROUND

Little is known about the risk to patients' health when using home-prepared enteral tube feeding. The objective of this study was to explore the differences in hygiene conditions and microbial load of different types of home-prepared enteral tube feeding and explore associations between those differences and food handlers' characteristics.

METHODS

We evaluated 96 enteral formulations, considering 3 types used by adult patients: homemade enteral preparations (HEPs), blended enteral preparations (BEPs), and commercial enteral formulas (CEFs). Enteral formulations were collected from homes and microbiologically analyzed. Hygiene criteria were assessed using a checklist, applied during the handling stages. The profile of the food handler was reviewed using a questionnaire.

RESULTS

82.3% (79/96) exceeded acceptable bacterial counts, which was 10³ colony-forming units per gram for aerobic mesophilic microorganisms and for total coliforms (35 °C), Escherichia coli, Staphylococcus sp, and Staphylococcus coagulase-positive, if present in the enteral formulations. The number of inadequate samples was higher in HEPs and BEPs than in CEFs. Considering the hygiene criteria, the home-prepared enteral tube feedings did not differ significantly. There was a significant difference among hygiene conditions considering the variables "monthly family income" and "food training."

CONCLUSION

Regardless of the type of enteral formulations used by patients, when handled at home, there was a risk of contamination. However, contaminants present in enteral formulations can be easily controlled with improvements in hygiene measures as well as with greater guidance and control during the handling stages.

An Evaluation of the Nutritional Value and Physical Properties of Blenderised Enteral Nutrition Formula: A Systematic Review and Meta-Analysis

Background: Although there are merits in using commercial “enteral nutrition formula” (ENF) compared with blended ENF, there is a growing preference for the use of blended ENF in many countries globally. However, the nutritional value and physical properties of blended ENF compared with commercial ENF may be limiting its use. We have not found any evidence of a meta-analysis on the nutritional value of blended diets in the adult population. Aim: The aim of this review was to compare the nutritional value, physical properties, and clinical outcomes of blended ENF with commercial ENF. Methods: The preferred reporting items for systematic reviews and meta-analyses were used for this review. The search strategy was based on a Population, Intervention, Comparator, Outcome framework. The following databases; Pubmed, EMBASE, PSYCInfo, and Google scholar were searched for articles of interest using keywords, Medical Subject Heading (MeSH) and Boolean operators (AND/OR) from the inception of each database until 23 February 2020. The articles were evaluated for quality. Results: Based on the systematic review and meta-analysis, four distinct themes were identified; Nutritional value, Physical properties, Clinical outcomes; and Adverse events. The findings of this review showed inconsistencies in the macronutrient and micronutrient values of the blenderised ENF compared with the commercial ENF. The results of the meta-analysis demonstrated that there were no significant differences (p > 0.05) between the blenderised ENF and the commercial ENF in relation to the fat and protein contents of the diets. However, the blenderised ENF was significantly lower (p < 0.05) than the commercial ENF regarding the energy content of the diets, with an overall mean difference of −29.17 Kcal/100 mL (95% CI, −51.12, −7.22) and carbohydrate content with an overall mean difference of -5.32 g/100 mL (95% CI, −7.64, −3.00). In terms of sodium, potassium, and vitamin A, there were no significant differences (p > 0.05) between the blenderised and commercial ENF, although significant differences (p < 0.05) were observed between the two diets with respect to calcium, phosphorus, magnesium, zinc, iron, and vitamin C contents. Furthermore, the blenderised ENF showed significantly higher levels (p < 0.05) of viscosity and osmolality than the commercial ENF. The significantly lower levels of some of the macro-nutrients and micro-nutrients in the blenderised ENF compared with the commercial ENF and the difference in the expected nutritional values may be due to the fact blenderised ENF is produced from common foods. Thus, the type of foodstuffs, cooking, and processing methods may lead to loss of nutrients and energy density. The deficits in the energy content and some of the macro- and micro-nutrients in the blenderised ENF compared with commercial ENF may have implications for patients’ health and clinical outcomes. The clinical implications of the underdelivering of nutrients may include increased risk of undernutrition, including energy malnutrition, which could have a negative effect on body composition and anthropometric parameters, morbidity, mortality, length of hospital stay, and costs. For outpatient care, this could increase the risk of hospital re-admission and homecare costs. Additionally, the higher viscosity and osmolality of the blenderised ENF compared with the commercial ENF can increase the risk of complications, including tube blockage, and impaired delivery of feed, water, and medications, with significant implications for patients’ nutritional status and health outcomes. Conclusion: The results of this systematic review and meta-analysis identified significant variability in the nutritional value of blenderised ENF compared with commercial ENF. Furthermore, the nutritional values of the blenderised ENF do not meet the expected recommended levels compared with commercial ENF and these may have implications for patients’ nutritional status and health outcomes, including the effect on body composition, morbidity, mortality, hospital re-admission, and costs. Further studies are needed to elucidate the nutritional value of blenderised ENF on patients’ clinical outcomes.

Reduction in Healthcare Utilization With Transition to Peptide-Based Diets in Intolerant Home Enteral Nutrition Patients

BACKGROUND

Since the introduction of percutaneous endoscopic gastrostomy in the 1980s, the prevalence of home enteral nutrition (HEN) support has increased significantly. Despite these increases, many patients are unable to tolerate standard polymeric formulas (SPFs), resulting in significant healthcare resource utilization. Peptide-based diets (PBDs) have emerged as a viable option in SPF-intolerant patients; however, data in the HEN population are lacking.

METHODS

Retrospective review of our prospectively maintained HEN database was conducted to assess tolerance, efficacy, and impact on healthcare utilization in patients on PBDs.

RESULTS

From January 1, 2016, to May 1, 2018, 95 patients were placed on PBDs, with 53 patients being started directly and 42 patients being transitioned from SPFs. In patients transitioned to PBDs, symptoms of nausea and vomiting, diarrhea, abdominal pain, and distention improved significantly. Healthcare utilization also declined significantly, including mean number of phone calls (1.8 ± 1.6 to 1.1 ± 0.9, P = 0.006), mean number of emergency room visits (0.3 ± 0.6 to 0.09 ± 0.3, P = 0.015), and mean number of provider visits (1.3 ± 1.3 to 0.3 ± 0.5, P < 0.0001).

CONCLUSIONS

Overall, PBDs were well tolerated and resulted in significant improvements in symptoms of gastrointestinal distress and healthcare utilization in patients intolerant to SPFs.
