- A randomized, controlled fall-prevention study including 199 patients operated on for femoral neck fracture reduced inpatient falls and injuries. No statistically significant effects of the intervention program could be detected after discharge. It seems that fall-prevention must be part of everyday life in fall-prone old people. Introduction This study evaluates whether a postoperative multidisciplinary, multifactorial fall-prevention program performed by a geriatric team that reduced inpatient falls and injuries had any continuing effect after discharge. The intervention consisted of staff education, systematic assessment and treatment of fall risk factors and vitamin D and calcium supplementation. Methods The randomized, controlled trial with a one-year follow-up at Umea University Hospital, Sweden, included 199 patients operated on for femoral neck fracture, aged >= 70 years. Results After one year 44 participants had fallen 138 times in the intervention group compared with 55 participants and 191 falls in the control group. The crude postoperative fall incidence was 4.16/1,000 days in the intervention group vs. 6.43/1,000 days in the control group. The incidence rate ratio was 0.64 (95% CI: 0.40-1.02, p = 0.063). Seven new fractures occurred in the intervention group and 11 in the control group. Conclusion A team applying comprehensive geriatric assessment and rehabilitation, including prevention and treatment of fall-risk factors, reduced inpatient falls and injuries, but no statistically significant effects of the program could be detected after discharge. It seems that fall-prevention must be part of everyday life in fall-prone elderly.

- Summary: In a study of a 12-year population-based injury register, Umeå, Sweden, we analyzed the fracture mechanisms and fracture pattern in men and women 50 years and older. Low-energy trauma was responsible for the major and costliest part of the fracture panorama, but the pattern differs between age groups. Introduction: Osteoporosis-related fracture is a major health problem: the number of hip fractures is expected to double to 2030. While osteoporosis is one of many risk factors, trauma is almost always involved. Therefore, we analyzed injury mechanisms in patients aged over 50. Methods: We registered injury mechanism, cause, diagnosis in all trauma patients at Umeå University hospital, Sweden. This population-based register (1993–2004) comprises a total of 113,668 injuries (29,189 fractures). Patients ≥50 years contributed to 13,279 fractures. Results: Low-energy trauma (fall <1 m) caused 53% of all fractures ≥50 years and older. In those over 75 low-energy trauma caused >80%. The seasonal variation of fractures was maximally 25%. With increasing age, proximal fractures became more common, in both upper and lower extremities. Proximal locations predominate in older age groups. Conclusions: Low-energy trauma was responsible for the largest and costliest part of the fracture panorama. In fact, almost all fractures in middle-aged and old people were caused by low-energy mechanisms; thus, most fractures in these patients have a fragility component, and the contribution of osteoporosis-related fractures is more important than previously thought. A better understanding of injury mechanisms also in low-energy trauma is a prerequisite for preventive interventions.

- 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.
