OBJECTIVE: An economic evaluation of therapeutic massage, exercise, and lessons in the Alexander technique for treating persistent back pain. DESIGN: Cost consequences study and cost effectiveness analysis at 12 month follow-up of a factorial randomised controlled trial. PARTICIPANTS: 579 patients with chronic or recurrent low back pain recruited from primary care. INTERVENTIONS: Normal care (control), massage, and six or 24 lessons in the Alexander technique. Half of each group were randomised to a prescription for exercise from a doctor plus behavioural counselling from a nurse. MAIN OUTCOME MEASURES: Costs to the NHS and to participants. Comparison of costs with Roland-Morris disability score (number of activities impaired by pain), days in pain, and quality adjusted life years (QALYs). Comparison of NHS costs with QALY gain, using incremental cost effectiveness ratios and cost effectiveness acceptability curves. RESULTS: Intervention costs ranged from Great British Pounds 30 for exercise prescription to Great British Pounds 596 for 24 lessons in Alexander technique plus exercise. Cost of health services ranged from Great British Pounds 50 for 24 lessons in Alexander technique to Great British Pounds 124 for exercise. Incremental cost effectiveness analysis of single therapies showed that exercise offered best value (Great British Pounds 61 per point on disability score, Great British Pounds 9 per additional pain-free day, Great British Pounds 2,847 per QALY gain). For two-stage therapy, six lessons in Alexander technique combined with exercise was the best value (additional Great British Pounds 64 per point on disability score, Great British Pounds 43 per additional pain-free day, Great British Pounds 5,332 per QALY gain). CONCLUSIONS: An exercise prescription and six lessons in Alexander technique alone were both more than 85% likely to be cost effective at values above Great British Pounds 20,000 per QALY, but the Alexander technique performed better than exercise on the full range of outcomes. A combination of six lessons in Alexander technique lessons followed by exercise was the most effective and cost effective option.
