- The aim of this population-based prospective study was to determine the incidence of limb fracture by site and gender in different regions of Europe. Men and women aged 50-79 years were recruited from population registers in 31 European centers. Subjects were invited to attend for an interviewer-administered questionnaire and lateral spinal radiographs. Subjects were subsequently followed up using an annual postal questionnaire which included questions concerning the occurrence of new fractures. Self-reported fractures were confirmed where possible by radiograph, attending physician or subject interview. There were 6451 men and 6936 women followed for a median of 3.0 years. During this time there were 140 incident limb fractures in men and 391 in women. The age-adjusted incidence of any limb fracture was 7,3/1000 person-years [pyrs] in men and 19 per 1000 pyrs in women, equivalent to a 2,5 times excess in women. Among women, the incidence of hip, humerus and distal forearm fracture, though not 'other' limb fracture, increased with age, while in men only the incidence of hip and humerus fracture increased with age. Among women, there was evidence of significant variation in the occurrence of hip, distal forearm and humerus fractures across Europe, with incidence rates higher in Scandinavia than in other European regions. though for distal forearm fracture the incidence in east Europe was similar to that observed in Scandinavia. Among men, there was no evidence of significant geographic variation in the occurrence of these fractures. This is the first large population-based study to characterize the incidence of limb fracture in men and women over 50 years of age across Europe. There are substantial differences in the descriptive epidemiology of limb fracture by region and gender.

Journal article (peer-reviewed)abstract
- Background: The Multiple Outcomes of Raloxifene Evaluation (MORE) study showed that treatment with raloxifene reduces the risk of vertebral fracture and breast cancer in postmenopausal women with osteoporosis. Objective: Based on the MORE study the aim of the present study was to assess the cost effectiveness of raloxifene (compared with no treatment) for the treatment of osteoporosis in postmenopausal women in Sweden. Design: A revised version of a previously developed computer simulation model was used. The impact of the risk-reducing effect of raloxifene on vertebral fractures and breast cancer on cost effectiveness was analysed using a clinical and a morphometric definition of vertebral fracture. Benefits of raloxifene treatment were measured in quality-adjusted life-years (QALYs) and life-years gained. The study estimated the cost effectiveness mainly from a healthcare perspective but the cost effectiveness taking a societal perspective was also analysed. Results: Intervention costs (in Swedish kronor [SEK] and euros [E], year 2001 values) in postmenopausal women with a relative risk of vertebral fracture of 2 were SEK372 000 (E40 000) SEK303 000 (E33 000) and SEK263 000 (E28 000) per QALY for women aged 60, 70 and 80 years, at start of treatment, respectively, when the clinical vertebral definition was used. The cost effectiveness using a clinical morphometric vertebral fracture definition was similar to the cost effectiveness using a clinical vertebral fracture definition. Conclusions: In relation to accepted threshold values for cost per QALY in Sweden, this model indicates, with its underlying assumptions and data that raloxifene (compared with no treatment) is cost effective for the treatment of postmenopausal women at an increased risk of vertebral fracture. from the Swedish healthcare and societal perspectives.

The cost-effectiveness of risedronate in the treatment of osteoporosis: an international perspective
- 2006
-
In: Osteoporosis International. - : Springer Science and Business Media LLC. - 1433-2965 .- 0937-941X. ; 17:7, s. 996-1007

Journal article (peer-reviewed)abstract
- Introduction: Risedronate, a bisphosphonate for treatment and prevention of osteoporosis, has been shown in several clinical trials to reduce the risk of fractures in postmenopausal women with osteoporosis. The cost-effectiveness of risedronate treatment has previously been evaluated within different country settings using different model and analysis approaches. The objective of this study was to assess the cost-effectiveness of risedronate in postmenopausal women in four European countries-Sweden, Finland, Spain, and Belgium-by making use of the same modelling framework and analysis setup. Methods: A previously developed Markov cohort model for the evaluation of osteoporosis treatments was used to estimate the cost-effectiveness of risedronate treatment. For each country, the model was populated with local mortality, fracture incidence, and cost data. Hip fractures, clinical vertebral fractures, and wrist fractures were included in the model. Results: The incremental cost per quality-adjusted life years (QALY) gained from a 5-year intervention with risedronate compared to "no intervention" in 70-year-old women at the threshold of osteoporosis [T-score = -2.5 based on National Health and Nutrition Examination Survey (NHANES) III data] and previous vertebral fracture was estimated to be E860, E19,532, E11,782, and E32,515 in Sweden, Finland, Belgium, and Spain, respectively. Among 70-year-old women at the threshold of osteoporosis without previous fracture the estimated cost per QALY gained ranged from E21,148 (Sweden) to E80,100 (Spain). The differences in cost-effectiveness between countries are mainly explained by different costs (fracture and treatment costs), fracture risks, and discount rates. Based on cost per QALY gained threshold values found in the literature, the study results indicated risedronate to be cost effective in the treatment of elderly women with established osteoporosis in all the included countries. Conclusions: At a hypothetical threshold value of E40,000 per QALY gained, the results in this study indicate that risedronate is a cost-effective treatment in elderly women at the threshold of osteoporosis (i.e., a T-score of -2.5) with prevalent vertebral fractures in Sweden, Finland, Belgium, and Spain.

Optimal age for preventing osteoporosis after menopause depends on effects of stopping treatment
- 2002
-
In: Bone. - 1873-2763. ; 30:5, s. 754-758
-
Journal article (peer-reviewed)abstract
- The aim of this study was to model the effect of short (3 year) treatments for osteoporosis at different times after menopause on the risk of osteoporotic fracture and to assess the impact of strategies to target high-risk individuals. Treatment efficacy for hip, proximal forearm, shoulder, and spine fracture were computed from the relationship between bone mineral density (BMD) and fracture in women from Sweden. Treatment that increased hip bone mineral density by 6% over untreated women saved 126 vertebral, hip, proximal humerus, and forearm fractures per 1000 women at the age of 50 years, provided that the effects of treatment persisted. Targeting women with osteoporosis at this age would save an additional 50% of fractures. With age, the number of fractures saved decreased moderately. At the age of 70 years, 133 fractures would be saved in women with osteoporosis compared to 198 in women with osteoporosis at the age of 50 years. Where the effect of treatment was assumed to wear off over 20 years after stopping treatment, the efficacy of treatment was reduced at all ages, but most markedly at the age of 50 years. Where all women aged 50 years were treated, the number of fractures saved per 1000 women decreased from 127 to 15 and, in the case of targeting women with osteoporosis, decreased from 198 to 27 per 1000 women. By contrast, with a persisting effect of treatment, the number of fractures saved increased markedly with advancing age. If all women were targeted at the age of 50 years, 15 fractures would be saved, whereas this increased to 55 per 1000 women at the age of 70 years. When treatment effects wore off more rapidly with an offset half-time of 2.5 years only 5 fractures were saved per 1000 women at the age of 50 years. This figure rose to 23 per 1000 at the age of 70 years. We conclude that, although uncertainty exists concerning the offset of effect of treatments, treatments should be optimally given to women without prior fractures in later life.

Health-related quality of life and radiographic vertebral fracture
- 2004
-
In: Osteoporosis International. - : Springer Science and Business Media LLC. - 1433-2965 .- 0937-941X. ; 15:2, s. 113-119
-
Journal article (peer-reviewed)abstract
- Background: Vertebral fractures are associated with back pain and disability; however, relatively little is known about the impact of radiographic vertebral fractures on quality of life in population samples. The aim of this study was to determine the impact of a recent radiographic vertebral fracture on health-related quality of life (HRQoL). Methods: Men and women aged 50 years and over were recruited from population registers in 12 European centers. Subjects completed an interviewer-administered questionnaire and had lateral spine radiographs performed. Subjects in these centers were followed prospectively and had repeat spinal radiographs performed a mean of 3.8 years later. Prevalent deformities were defined using established morphometric criteria, and incident vertebral fractures by both morphometric criteria and qualitative assessment. For each incident fracture case, three controls matched for age, gender, and center were selected: one with a prevalent deformity (at baseline) and two without prevalent deformities. All subjects were interviewed or completed a postal questionnaire instrument which included Short Form 12 (SF-12), the EQ-5D (former EuroQol), and the quality of life questionnaire of the International Osteoporosis Foundation (QUALEFFO). The median time from the second spinal radiograph until the quality of life survey was 1.9 years. Comparison between cases and their matched controls was undertaken using the signed rank test. Results: 73 subjects with incident vertebral fracture (cases), mean age 64.8 years (of whom 23 had a baseline deformity), and 196 controls, mean age 63.9 years (of whom 60 had a baseline deformity), were studied. There were strong correlations between the domain scores for each of the three instruments. There was no statistically significant difference in any of the domain scores between cases and those controls with a prevalent deformity. However, compared with the controls without a prevalent deformity the cases had significantly impaired quality of life as determined using the total QUALEFFO score (38.2 vs 33.7), the physical component score of the SF-12 (39.9 vs 43.7) and the health status score of the EQ-5D (62.3 vs 69.9). When the analysis was repeated after stratification of the cases by baseline deformity status (i.e., cases with and without a prevalent deformity at baseline), cases with a prevalent deformity had impaired quality of life compared with their matched controls, both with and without a prevalent deformity. In contrast there was no significant difference in quality of life among the cases without a prevalent deformity and either control group. Conclusion: In this population-based study a recent vertebral fracture was associated with impairment in quality of life, though this was mainly among those who had sustained a previous vertebral deformity.

Journal article (peer-reviewed)abstract
- 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.

Cost-effectiveness of risedronate for the treatment of osteoporosis and prevention of fractures in postmenopausal women
- 2004
-
In: Osteoporosis International. - : Springer Science and Business Media LLC. - 1433-2965 .- 0937-941X. ; 15:11, s. 862-871
-
Journal article (peer-reviewed)abstract
- Randomized, double-blind, controlled studies have shown that treatment with risedronate reduces the risk of vertebral fracture in postmenopausal women with established vertebral osteoporosis. They also show that the drug decreases the risk of non-vertebral fractures in women with osteoporosis. The aim of this study was to investigate the cost-effectiveness of risedronate in postmenopausal women with osteoporosis. A Markov model was applied to a UK setting. Treatment effects were computed by meta-analysis of randomized, controlled trials and given over 5 years to subjects aged between 60 and 80 years. Quality-adjusted life years (QALYs) and life years gained were used as outcome measures. Intervention with risedronate was cost-effective in women aged 60 years and older. Cost savings were also found for postmenopausal women aged 70 years and older with established vertebral osteoporosis (a prior spine fracture and BMD T-score less than or equal to-2.5 SD). This treatment was cost-effective for women aged 65 years and older who had a prior vertebral fracture and a BMD T-score at the threshold of osteoporosis (T-score=-2.5 SD), and in women with a T-scoreless than or equal to-2.5 SD, but without a prior vertebral fracture. In women aged 60-80 years and at the threshold of osteoporosis (T-score=-2.5 SD) but without a prior vertebral fracture, treatment exceeded the threshold for cost-effectiveness. However, if an additional, independent risk factor was assumed (e.g., corticosteroid use) treatment became cost-effective.

Journal article (peer-reviewed)abstract
- Raloxifene reduces vertebral fracture risk in postmenopausal women with osteoporosis and established osteoporosis, but its efficacy in women with osteopenia has not been studied. The objective of this study was to evaluate the effect of raloxifene hydrochloride on the risk of vertebral fractures in postmenopausal women with osteopenia and to compare this effect with that in women with osteoporosis as defined by the bone mineral density (BMD) T-score at the hip. We studied the 3204 postmenopausal women with osteopenia or osteoporosis without vertebral fractures at baseline in the Multiple Outcomes of Raloxifene Evaluation trial. Compared with placebo, 60 mg/day raloxifene reduced the risk of new vertebral fractures at 3 years independent of baseline total hip BMD. The relative risk for new vertebral fractures for the raloxifene group compared with placebo was 0.53 (95% CI, 0.32-0.88) for those with osteopenia and 0.31 (0.06-0.71) for those with osteoporosis. In raloxifene-treated women the rate of vertebral fracture was similar in women with osteoporosis (2%) to that in women with osteopenia (1.9%). For clinically apparent vertebral fractures, the relative risk of fracture in the osteopenia group for raloxifene was 0.25 (0.04-0.63) compared with placebo. There were no new clinical vertebral fractures in women with osteoporosis receiving raloxifene, whereas four occurred in the placebo group. We conclude that treatment with 60 mg/day raloxifene significantly decreases the risk of new vertebral fractures and new clinical vertebral fractures in postmenopausal women without baseline vertebral fracture who have osteopenia or osteoporosis.
