Physical Activity in Cancer Patients in an Oncology Day Clinic - Implementing a Person-centered Program Led by Nurses

Background: Physical activity has demonstrated benefits in alleviating side effects and improving well-being in people with cancer. However, activity levels remain low during systemic treatment. Nurses are optimally positioned to lead interventions fostering an activity-friendly culture. Objective: This study aims to evaluate the feasibility and potential effects of the nurse-led, interprofessionally developed physical activity concept OncoMoveNurse in an outpatient oncology setting. Methods: Using a mixed-methods design over 15 months (10/2024-12/2025), the study includes implementation and evaluation phases. Quantitative data (n=50 patients, collected from 06/2025-09/2025) will assess primary (physical activity behavior) and secondary outcomes (self-efficacy, well-being, mood) via validated PROMs. Qualitative insights will be gathered through digital storytelling (n=2 patients, n=2 nurses) and one focus group (n=8 interprofessional team members). Inclusion criteria for patients include age ≥18, cancer diagnosis, at least three treatments in the day clinic, and sufficient German language skills. Intervention: OncoMoveNurse comprises five adaptable components: modular activity structure, safety framework, communication strategy, a team approach, and person-centered orientation. Supporting materials (e.g., posters, videos, exercise tools) and tailored implementation strategies were co-developed in alignment with core values. Analysis: Quantitative data will be analyzed using SPSS (paired t-tests, p\<.05); qualitative data via content analysis in MAXQDA. A mixed-methods synthesis will integrate findings. Ethics \& Data Protection: Patient data collection will commence following ethics approval. All data are anonymized, stored securely, and handled in accordance with Swiss data protection laws. Conclusion: This study will provide insights into the feasibility of nurse-led physical activity promotion in outpatient oncology and inform future outcome evaluations.
