Conditions for adherence to videoconference-based programs promoting adapted physical activity in cancer patients: a realist evaluation.

BACKGROUND: Although moderate physical activity (PA) during cancer treatment has been associated with improved quality of life, reduced side effects, and even lower mortality, many barriers to successful implementation remain. Digital technology has been perceived as an effective lever for overcoming access and motivational issues but few studies have been performed to confirm this assumption. The "VISIO-AJUST" study explored the factors affecting the conditions of adherence to video-conference-based PA programs in patients undergoing cancer treatment. METHODS: The VISIO-AJUST study was based on a qualitative successive case approach, guided by the principles of the realist evaluation, and applied to two French programs of PA, following three main steps: (1) Identification of factors likely to influence conditions of patients' adherence; (2) Elaboration and testing of explanatory "Context-Mechanism-Outcome (CMO)" configurations; (3) Refinement of CMO configurations, in order to understand what, how, for whom, and under what circumstances video-conference-based PA programs work. RESULTS: Five main CMO configurations were found to be associated with adherence to video-conferencing-based PA programs, promoting (i) accessibility and a supportive environment for adapted physical activity, (ii) a setting conducive to sociability despite distance, (iii) Confidence and security of practice, (iv) a combination of several motivational levers in favor of continuity of effort and progress, (v) regularity of the sessions, progressiveness in the effort and evaluation of progress as a basis for the adoption of a regular physical practice. CONCLUSION: This study provides original insights into the use of videoconferencing to enable patients to improve their PA during cancer treatment. Future research with long-term follow-up would allow for a better understanding of the key conditions promoting sustainable behavior change.

Delivering adapted physical activity by videoconference to patients with fatigue under immune checkpoint inhibitors: Lessons learned from the PACTIMe-FEAS feasibility study.

INTRODUCTION: Fatigue is one of the most frequent symptoms in anti-cancer immune therapy. Physical activity has been proven effective in reducing fatigue, but unmet needs remain regarding the provision and access to adapted programmes, which efficiently addresses the main barriers to PA. METHODS: The PACTIMe-FEAS study primarily aimed at primarily to evaluate the feasibility and the acceptability of a videoconference-based 6-month programme promoting physical activity, and secondarily to assess its potential post-immediate and short-term effectiveness in reducing fatigue in cancer patients under immune therapy. Numeric self-reported questionnaires (Visual Analogue Scale-fatigue, Multidimensional Fatigue Inventory, International Physical Activity Questionnaire, Échelle de Motivation envers l'Activité Physique en contexte de Santé, Medical Outcomes Study 36-Item Short Form Health Survey, Hospital Anxiety and Depression Scale and Insomnia Severity Index) were completed by participants through an online secure platform at three time points: just before (T1), and after (T2) the programme, and 3 months later (T3). RESULTS: Sixteen participants (50% male, 50% female, mean age 54 years, 69% melanoma, 31% overweight), with moderate-to-severe fatigue, entered the internet-delivered intervention; 14 completed it, with an average completion rate of physical activity supervised sessions of 75%. Satisfaction was high, confirming a demand for group format, personalised approach, professional guidance and home-based device, to support the practice of regular physical activity. A decrease in fatigue was observed at the end of the programme. DISCUSSION: The recruitment process did prove to be challenging, with a relatively small eligible population, and will need to be reconsidered to envision a larger scale trial. But here and now, this feasibility study provides the first promising foundations to develop further research on the effectiveness of an original remote programme.
