BACKGROUND: Childhood cancer survivors face high risks of adverse late health effects. Long-term follow-up care for childhood cancer survivors is crucial to improve their health and quality of life. However, implementation remains a challenge. To support implementation of high-quality long-term follow-up care, we explored expected barriers and facilitators for establishing this follow-up care among healthcare providers from four European clinics. METHODS: A qualitative study was conducted using four focus groups comprising 30 healthcare providers in total. The semi-structured interview guide was developed based on the Grol and Wensing framework. Data was analyzed following a thematic analysis, combining both inductive and deductive approaches to identify barriers and facilitators across the six levels of Grol and Wensing: innovation, professional, patient, social, organizational and economic and political. RESULTS: Most barriers were identified on the organizational level, including insufficient staff, time, capacity and psychosocial support. Other main barriers included limited knowledge of late effects among healthcare providers outside the long-term follow-up care team, inability of some survivors to complete the survivor questionnaire and financial resources. Main facilitators included motivated healthcare providers and survivors, a skilled hospital team, collaborations with important stakeholders like general practitioners, and psychosocial care facilities, utilization of the international collaboration and reporting long-term follow-up care results to convince hospital managers. CONCLUSION: This study identified several factors for successful implementation of long-term follow-up care for childhood cancer survivors. Our findings showed that specific attention should be given to knowledge, capacity, and financial issues, along with addressing psychosocial issues of survivors.

INTRODUCTION: Long-term survival after childhood cancer often comes at the expense of late, adverse health conditions. However, survivorship care is frequently not available for adult survivors in Europe. The PanCareFollowUp Consortium therefore developed the PanCareFollowUp Care Intervention, an innovative person-centred survivorship care model based on experiences in the Netherlands. This paper describes the protocol of the prospective cohort study (Care Study) to evaluate the feasibility and the health economic, clinical and patient-reported outcomes of implementing PanCareFollowUp Care as usual care in four European countries. METHODS AND ANALYSIS: In this prospective, longitudinal cohort study with at least 6 months of follow-up, 800 childhood cancer survivors will receive the PanCareFollowUp Care Intervention across four study sites in Belgium, Czech Republic, Italy and Sweden, representing different healthcare systems. The PanCareFollowUp Care Intervention will be evaluated according to the Reach, Effectiveness, Adoption, Implementation and Maintenance framework. Clinical and research data are collected through questionnaires, a clinic visit for multiple medical assessments and a follow-up call. The primary outcome is empowerment, assessed with the Health Education Impact Questionnaire. A central data centre will perform quality checks, data cleaning and data validation, and provide support in data analysis. Multilevel models will be used for repeated outcome measures, with subgroup analysis, for example, by study site, attained age, sex or diagnosis. ETHICS AND DISSEMINATION: This study will be conducted in accordance with the guidelines of Good Clinical Practice and the Declaration of Helsinki. The study protocol has been reviewed and approved by all relevant ethics committees. The evidence and insights gained by this study will be summarised in a Replication Manual, also including the tools required to implement the PanCareFollowUp Care Intervention in other countries. This Replication Manual will become freely available through PanCare and will be disseminated through policy and press releases.
