Co-Design and Evaluation Protocol for the RECOVER Model of Care After Childhood Cancer Treatment

Background: Advances in diagnosis and treatment have significantly increased survival rates for childhood cancer, leading to a growing population of long-term survivors. However, these survivors face substantial physical and psychological sequelae that affect both the child and their family. We developed the RECOVER model of care to support childhood cancer survivors as they transition from the end of their planned treatment to survivorship, addressing the broader health and wellness needs beyond medical surveillance. The primary objectives are to assess the feasibility and acceptability of the RECOVER model of care in routine paediatric oncology practice. Secondary objectives include evaluating preliminary efficacy outcomes and identifying factors that influence the successful adoption and integration of the model. Methods: The study comprises a Type 2 Hybrid Implementation/Effectiveness non-randomised controlled trial to compare historical and prospective data. Quantitative data will assess feasibility, reach, effectiveness, adoption, maintenance, and implementation. The qualitative component will assess end-user acceptability and appropriateness through focus groups, surveys, and interviews. Quantitative and qualitative results will be integrated during the interpretation phase to provide complementary insights into the interconnected contextual factors that facilitate the model uptake. Discussion: The RECOVER model of care aims to offer a robust approach to survivorship care, facilitating the continuous monitoring and management of long-term and late effects in childhood cancer survivors. This model has the potential to significantly improve the quality of life and health outcomes for this vulnerable population by addressing their comprehensive needs in a timely and systematic manner.
