ABSTRACT: Study Design. Multi-centred randomized controlled trial with quality of life and resource use data collected.Objective. The objective of this study is to evaluate the cost-effectiveness of yoga intervention plus usual care compared with usual care alone for chronic or recurrent low back pain.Summary of Background Data. Yoga has been shown as an effective intervention for treating chronic or recurrent low back pain. However, there is little evidence on its cost-effectiveness. The data is extracted from a pragmatic, multi-centred, randomized controlled trial which has been conducted to evaluate the effectiveness and cost effectiveness of a 12-week progressive programme of yoga plus usual care in patients with chronic or recurrent low back pain.Methods. With this trial data, a cost-effectiveness analysis over the time period of 12 months from both perspectives of the UK National Health Service and the societal is presented. Main outcome measure is an incremental cost per quality adjusted life year. Results: From the perspective of the NHS, yoga intervention yields an incremental cost effectiveness ratio of £13,606 per QALY. Given a willingness to pay for an additional QALY of £20,000, the probability of yoga intervention being cost effective is 72%. From the perspective of the society, yoga intervention is a dominant treatment over usual care alone. This result is surrounded by fewer uncertainties - the probability of yoga being cost effective reaches 95% at a willingness to pay for an additional QALY of £20,000. Sensitive Analyses suggest the same results that yoga intervention is likely to be cost-effective in both perspectives.Conclusion. Based on this trial 12 weekly group classes of specialised yoga is likely to be a cost-effective intervention for treating patients with chronic or recurrent low back pain.
