Nudging people with Type 2 diabetes towards sustained adherence to self-management: a cluster randomized controlled trial

- The study aims to evaluate the effects of a personalized behavioral intervention (‘FEEDBACK’) developed to improve self-management behavior in adults with type 2 diabetes. FEEDBACK is a resource-minimizing intervention designed to be delivered by general practitioners (GPs) in routine primary care settings. The study is a cluster randomized controlled trial (RCT) with six months follow-up.- In Japan, where the implementation of primary care policy has just begun, it is necessary to introduce evidence-based, person-centered diabetic care into the practice of GPs nationwide. If we could link our FEEDBACK intervention with improved patient outcomes and delivery in primary care, this would provide further justification for stronger primary care services and investment in primary care in Japan.2022:- After numerous study implementation challenges and delays encountered in 2020 and 2021 due to the COVID-19 pandemic, we have now managed to make good progress in the recruitment process. Eighteen GP practices have been recruited so far, which is close to our initial sample size objective (n=20). We would like to recruit a few more practices to ensure that our pre-registered minimum effect size of interest can be detectable.- As we made good process on the recruitment process, we submitted the study protocol for publication in an international peer-reviewed journal in January 2023. The manuscript has been accepted for publication in the journal 'Trials'.
