Real‐World Effectiveness of Osteoporosis Medications in France: A Nationwide Cohort Study

Description
Summary:Although drugs for osteoporosis have been demonstrated to be effective in reducing fracture risk in placebo‐controlled clinical trials, data on effectiveness in real‐world practice is limited. Data from the French national health insurance claims database (SNDS) were used to follow five cohorts of women aged ≥55 years after initiating treatment for ≥6 months with either denosumab, zoledronic acid, oral bisphosphonates, raloxifene, or teriparatide in 2014–2016. Fracture incidence was compared within each cohort between the 3 months following initiation (baseline fracture risk) and the 12month, 18month, and 24 month postinitiation periods. Data are presented as incidence rate ratios (IRRs) with their 95% confidence intervals (CIs)s. Overall, 67,046 women were included in the denosumab cohort, 52,914 in the oral bisphosphonate cohort, 41,700 in the zoledronic acid cohort, 11,600 in the raloxifene cohort, and 7510 in the teriparatide cohort. The baseline vertebral fracture rate ranged from 1.74 per 1000 person years (‰PY) in the raloxifene cohort to 34.75‰PY in the teriparatide cohort, and the baseline hip fracture rate from 0.70‰PY in the raloxifene cohort to 10.52‰PY in the zoledronic acid cohort. Compared with the baseline fracture rate, vertebral fractures involving hospitalization were significantly reduced in the 3–24–month postinitiation period with denosumab (IRR 0.6; 95% CI, 0.5–0.7), zoledronic acid (IRR 0.4; 95% CI, 0.3–0.4), teriparatide (IRR 0.3; 95% CI, 0.2–0.5), and oral bisphosphonates (IRR 0.6; 95% CI, 0.4–0.8). Hip fracture incidence was reduced with denosumab (IRR 0.8; 95% CI, 0.6–0.9), but higher for oral bisphosphonates (IRR 1.7; 95% CI, 1.2–2.3); no significant change in hip fracture rate was observed for zoledronic acid, teriparatide, or raloxifene. A reduction in nonvertebral, non‐hip fracture incidence was observed only in the denosumab cohort (IRR 0.8; 95% CI, 0.7–0.9). These findings indicate that treatment with osteoporosis drugs is effective in the real‐world setting. © 2023 The Authors.
