Diabetes management using a clinical guideline versus usual practice: a feasibility trial-based qualitative study among Ayurvedic practitioners and patients in Nepal

Background: Type 2 diabetes mellitus (T2DM) is common in Nepal, where many people seek primary care through Ayurveda, a widely practiced traditional medical system. However, concerns remain about variability in clinical practice and the quality of care provided by Ayurvedic practitioners. No evidence-based clinical practice guideline (EB-CPG) currently exists for managing T2DM in Ayurveda. To address this, an EB-CPG was developed, and a feasibility trial was conducted to inform a future definitive cluster randomized controlled trial evaluating whether the EB-CPG improves T2DM management compared to usual clinical practice. Objectives: To explore the experiences and perspectives of Ayurvedic practitioners and patients regarding the two treatment groups (EB-CPG-based care versus usual clinical practice) and participation in the feasibility trial. Design: Constructivist qualitative study. Methods: Semi-structured interviews were conducted with Ayurvedic practitioners and patients. Data were analyzed thematically using an inductive approach and the Framework Method. Results: A total of 41 Ayurvedic practitioners and patients were interviewed. Common themes identified across both groups included facilitators and challenges in the trial patient recruitment, challenges in usual clinical care, experiences with EB-CPG-based care (predominantly positive), ease and difficulties of monthly follow-ups, and pros and cons of patient diaries for assessing medication compliance. Practitioner-specific themes included the diverse populations they serve; patients' motivations for choosing Ayurveda over Western medicine; their motivations for trial participation; balancing clinical duties with the trial demands; confusion about trial roles and responsibilities; and other trial-related issues such as understanding processes and documentation, support and communication, coordination with data collectors, and finances and other resources. Conclusion: The EB-CPG-based approach for managing T2DM by Ayurvedic practitioners in Nepal was well-received and perceived as more beneficial than usual clinical practice. Trial experiences and perspectives were largely positive; however, several challenges related to trial conduct should be addressed in future studies, including the definitive cluster trial.
