Abstract

Blenderized tube feeding formulas (BTFF) are increasingly recognized as a viable alternative to conventional commercial tube feeding formulas (CTFF) for pediatric patients requiring enteral nutrition. This cross-sectional, exploratory study aimed to assess the experiences, attitudes, and perceived clinical benefits of BTFF use among Registered Dietitian Nutritionists (RDNs) working with gastrostomy-tube-dependent pediatric populations in the United States. A total of 146 RDNs completed a 45-item online survey, which gathered quantitative and qualitative data on BTFF familiarity, feasibility, clinical outcomes, caregiver factors, and institutional barriers. Findings revealed that while BTFF use remains variable across clinical settings, 55.8% of RDNs reported increased utilization over the past three to five years. Respondents identified key clinical benefits of BTFF, including improved gastrointestinal tolerance (53.7%), reduced symptoms (48.3%), and enhanced nutritional satisfaction (38.8%). Despite this, concerns related to food safety, nutrient adequacy, and preparation burden persist. RDNs with specialized training or certifications demonstrated significantly higher self-efficacy in BTFF-related knowledge, particularly in areas of preparation, delivery, and patient tolerance. Familiarity and comfort levels were notably higher among outpatient practitioners compared to those in hospital settings. Barriers to BTFF implementation were primarily practical in nature, with preparation time (71.2%), lack of caregiver knowledge (57.5%), and financial/resource constraints (53.4%) cited as top concerns. Most RDNs (65.3%) agreed that professional education programs could improve BTFF adoption, and over half (53.1%) supported interdisciplinary training for broader healthcare teams. The study also highlighted the need for standardized BTFF resources, such as food safety guidance and recipe protocols, to support safe and effective implementation. This research underscores the importance of comprehensive RDN training, institutional support, and family-centered education in optimizing BTFF use. Findings contribute to the growing evidence base that may inform future clinical guidelines, policy development, and research on the integration of whole-food enteral nutrition in pediatric care.
