Knowledge and clinical practice of ASPEN registered dietitian nutritionist members regarding blenderized tube feedings

Background: Blenderized tube feedings (BTFs) are used by patients/caregivers who report improvements in gastrointestinal tolerance compared with standard commercial feedings. Despite positive outcomes, registered dietitian nutritionists or international equivalents (RDN/Is) hesitate to recommend BTFs. We aimed to determine if an association exists between dietitian characteristics and willingness to recommend BTFs. Methods: A BTF-specific survey (N = 157) assessed for validity and reliability was administered to the American Society for Parenteral and Enteral Nutrition (ASPEN) RDN/I members. Binary logistic regression analyses examined the association between age, years of clinical practice, BTF training/education, patient population served, and willingness to recommend BTFs. Results: The response rate was 4.3% of ASPEN RDN/I members. Most respondents were White females with a median age of 39.0 years and 12 years of clinical experience. Although 98.7% of respondents expressed a willingness to support and 73% to recommend BTFs, 60% were not using BTFs in clinical practice. For 94.8% of RDN/Is, the primary reason for BTF use was patient/caregiver requests. After adjustment for age and years of clinical practice, RDN/Is who served pediatric populations (odds ratio [OR] = 4.28; 95% CI, 1.52–12.09) or used three or more professional resources (OR = 2.49; 95% CI, 1.12–5.57), industry-sponsored resources (OR = 3.15; 95% CI, 1.39–7.15), or one or more experiential learning resources (OR = 3.14; 95% CI, 1.38–7.17) were more likely to recommend BTFs whereas those serving adults were less likely to recommend BTFs (OR = 0.33; 95% CI, 0.12–0.95). Conclusion: Pediatric RDN/Is and individuals with BTF-specific education/training were more inclined to recommend BTFs.
