Cost-effectiveness of a combined physical exercise and psychosocial training intervention for children with cancer: Results from the quality of life in motion study.

This study was performed to estimate the cost-effectiveness of a combined physical exercise and psychosocial intervention for children with cancer compared with usual care. Sixty-eight children, aged 8-18 years old, during or within the first year post-cancer treatment were randomised to the intervention (n = 30) and control group (n = 38). Health outcomes included fitness, muscle strength and quality adjusted life years; all administered at baseline, 4- and 12-month follow-up. Costs were gathered by 1 monthly cost questionnaires over 12 months, supplemented by medication data obtained from pharmacies. Results showed no significant differences in costs and effects between the intervention and control group at 12-month follow-up. On average, societal costs were €299 higher in the intervention group than in the control group, but this difference was not significant. Cost-effectiveness acceptability curves indicated that the intervention needs large societal investments to reach reasonable probabilities of cost-effectiveness for quality of life and lower body muscle strength. Based on the results of this study, the intervention is not cost-effective in comparison with usual care.
