Summary

Completing cancer treatment is a major milestone for adolescents and their families —bringing relief, happiness and hope, but also uncertainty and psychosocial challenges. This transition has received limited research attention, and evidence-based interventions for follow-up care is lacking.

This thesis comprises three studies and employ qualitative methods throughout, utilising reflexive thematic analysis inspired by Braun and Clarke to identify patterns in the collected data. Study I explored healthcare professionals’ experiences with transitioning adolescents off cancer treatment. Study II aimed to investigate the transition experiences of adolescents and their parents, focusing on their support and information needs. Study III build on findings from Studies I and II, were we identified needs for clearer information, better preparation, and stronger psychosocial support in the transition phase. To address these gaps, we co-created a nurse-led transition intervention with adolescents, parents, and healthcare professionals.

The intervention included two nurse consultations—one before and one after treatment completion—and a digital meeting with the family’s local network. The nurse-consultations aimed to provide tailored information, emotional support, and strategies for self-management, using tools to help adolescents express their needs. The digital meeting connected the family and hospital staff with key local contacts (e.g., GPs, school nurses, teachers) to ensure continuity of care. The nurse-led transition intervention was tested in a clinical out-patient setting with ten adolescents and their parents and assessed the feasibility and acceptability of the intervention through participant interviews. The increased involvement of nurses in the transition phase, through offering nurse consultations and network meetings, was positively evaluated by all parties involved, without requiring major changes.
