Abstract
Osteoporosis medications are recommended for elderly patients after a fragility fracture. However, we found substantial under-treatment in the post-fracture year, especially among patients who had not previously received such medications. Improved treatment of elderly patients experiencing fragility fractures is needed. INTRODUCTION: Osteoporosis medications are recommended for elderly patients after a fragility fracture, but under-treatment is common. We determined osteoporosis medication use after fragility fractures and examined associated factors. METHODS: Our cohort included elderly (age ≥66 years) Medicare-enrolled patients who sustained fragility fractures January 1, 2008-December 31, 2011. Osteoporosis medication prescriptions were determined in the 12 months after the index fracture. Using multivariate logistic models, we examined the association between post-fracture osteoporosis medication use and predictors. RESULTS: Of 145,185 patients with fragility fractures (mean age 80.9 ± 7.8 years; 91.2 % white; 81.3 % female), 29.9 % sustained hip, 31.8 % vertebral, and 38.4 % non-hip-non-vertebral fractures. Overall, 30.4 % of the cohort received an osteoporosis medication in the 12-month post-fracture period. Of patients not receiving an osteoporosis medication in the pre-index period (n = 108,344), 14.9 % of all patients, 16.3 % of women, and 10.3 % of men received one in the post-fracture period. Corresponding values for patients receiving an osteoporosis medication in the pre-index period (n = 36,841) were 76.2, 76.5, and 72.2 %. Odds of post-fracture osteoporosis medication use were 68 % higher for women than for men. Osteoporosis diagnosis (odds ratio, 1.55; P < 0.0001) and bone-mineral-density tests before an index fracture (odds ratio, 1.24; P < 0.001) were associated with post-fracture osteoporosis medication use. CONCLUSIONS: Less than one third of our cohort received an osteoporosis medication in the post-fracture year, when risk of a second fragility fracture is highest. In those not already previously treated with an osteoporosis medication, only about 1 in 7 patients received treatment.
