Barriers and Facilitators of Implementing an Online Weight Loss Program and App with Patients: A Qualitative Study of Registered Dietitian Nutritionists' Perspectives.

BACKGROUND: Registered dietitian nutritionists (RDNs) play a pivotal role in providing dietary education to patients seeking weight loss. Technology such as apps and online education may support RDNs and patients by providing platforms for enhanced communication and tracking. OBJECTIVE: To explore RDNs' perceptions of using an online weight management program and app in dietetic practice, including perceived barriers and facilitators to implementation. DESIGN: Qualitative study using semi-structured individual interviews. PARTICIPANTS: Participants (n=22) were credentialed RDNs currently working in weight loss practice with at least one year of experience. RDNs were purposively recruited to represent a range of years in practice, regions of the United States, and employer types INTERVENTION: Participant RDNs completed an eight-week study reviewing a newly developed online weight management program and companion web application. Activities included reviewing online educational sessions and testing the web application from patient and professional perspectives before participating in interviews. DATA ANALYSIS: Interview data were analyzed using reflexive thematic analysis within a constructivist research paradigm. Atlas.ti (Version 9.1.4) software was used to support data organization, coding, and management. RESULTS: Perceived barriers included patients' lack of time, self-motivation, and lower education level. Institutional barriers included a lack of insurance coverage and rigid workplace processes. Facilitators included patient preference for digital tools and improved accountability and self-monitoring. RDNs also described potential time savings by providing these materials to patients. CONCLUSIONS: Broader integration of digital platforms into nutrition care may benefit from streamlined workflows, institutional support, and reimbursement structures that facilitate technology-assisted practice. As demand for weight management services increases, RDNs are well positioned to lead implementation of evidence-based digital interventions that expand access, support long-term adherence, and promote equitable nutrition care.
