Abstract Background Peer support interventions in oncology have shown potential benefits for patients, including reduced psychological distress, improved empowerment, and enhanced care experience. However, the integration of Accompanying Patients (APs), trained individuals with personal experience of cancer into clinical teams remains variable, and the mechanisms underlying their impact are not fully understood. In France, although peer support initiatives are emerging, they often lack structure, evaluation, and coordination. Building on the PAROLE-Onco model developed in Quebec, this study aims to adapt, implement, and evaluate a structured peer-support program within the French healthcare system. Methods This study will use a mixed-methods, multiple-case design across ten oncology units with four organizational contexts. Quantitative data will be collected through validated questionnaires administered at baseline, 1 month, and 6 months for patients, or at inclusion, 1 month and 30 months for APs and healthcare professionals. Outcomes include quality of life (EORTC QLQ-C30), psychological well-being (HADS), empowerment (CASE-Cancer), care experience (PPE-15), patient-professional relationship (CADICEE), and professional perceptions of APs integration. Qualitative data will be gathered through semi-structured interviews, non-participant observations of meetings, and document analysis. This will explore the experiences of patients, APs, and professionals; the organizational adaptations and, the ethical and professional considerations associated with the program. Implementation fidelity, contextual adaptations, and stakeholders’ engagement will be systematically assessed. Discussion This study will provide an in-depth understanding of the integration processes and impacts of peer-support interventions in oncology care. By examining both patient-centered outcomes and organizational dynamics, it aims to identify key factors that facilitate sustainable integration of APs into clinical practice. Findings will inform strategies for scaling up and adapting peer-to-peer support programs across diverse healthcare settings, contributing to the strengthening of patient partnership and participatory approaches in cancer care. Trial registration Trial is registered under Clinical Trails Registry – France (NCT06817655), registered on 10th February 2025. |
