Cost-effectiveness of raloxifene in the UK: an economic evaluation based on the MORE study

Raloxifene treatment has been shown to reduce the risk of vertebral fractures and breast cancer in postmenopausal women. The long-term economic implications of treatment with raloxifene have not yet been investigated. The aim of this study was to assess the cost-effectiveness of treating postmenopausal women in the UK with raloxifene. A previously developed computer simulation model was used to estimate the cost-effectiveness of osteoporotic treatments with extra skeletal benefits. The model was populated with epidemiological data and cost data relevant for a UK female population. Data on the effect of treatment were taken from the Multiple Outcomes of Raloxifene (MORE) study., which recruited women with low bone mineral density or with a prior vertebral fracture. Cost-effectiveness was estimated using Quality Adjusted Life Years (QALYs) and life years gained as primary outcome measures. The cost per QALY gained of treating post menopausal women without prior vertebral fractures was pound18,000, pound23,000, pound18,000 and pound21,000 at 50. 60, 70 and SO years of age. Corresponding estimates for women with prior vertebral fractures were pound10,000, pound24,000, pound18,000 and pound20,000. In relation to threshold values that are recommended in the UK. the analysis suggests that raloxifene is cost-effective in the treatment of postmenopausal women at an increased risk of vertebral fractures.
