Background: Several family-based efficacious pediatric weight management interventions (PWMIs) have been developed to reduce child weight status. These programs are typically based in larger cities delivered by an interdisciplinary team in a hospital or medical center. The degree to which these efficacious PWMIs have been translated to, and are feasible in, rural or micropolitan areas is unclear. This study protocol describes a pilot Type III hybrid effectiveness-implementation (T3HEI) trial testing a multilevel strategy that focuses on the adoption, implementation, and sustainability of a PWMI online training program and resource package designed for implementation in micropolitan and rural areas. Methods: The trial design employed the Reach, Effectiveness, Adoption, Implementation and Maintenance (RE-AIM) framework to evaluate outcomes and the Promoting Action on Research Implementation in Health Services framework to specify potential mechanisms of adoption, implementation, and sustainability. The study will test the feasibility of a fund and contract dissemination strategy in the adoption of a PWMI in four to eight rural communities, compare a learning collaborative implementation strategy including embedded training and sustainability action planning with communities who receive the PWMI online program and resources alone, and determine whether the PWMI reach, effectiveness, and maintenance are of magnitude similar to previous effectiveness trials. The dissemination and implementation process focused on an integrated research-practice partnership process model that includes a systems-based approach with multiple sectors and vertical decision-making representation. Conclusions: Our pilot T3HEI study has the potential to inform how best to move and sustain evidence-based PWMIs into practice. The findings will inform larger scale dissemination, implementation, and sustainability efforts in medically underserved areas across the country. Trial registration: This protocol is registered with clinicaltrials.gov (NCT04719442).
