Trends in anti-osteoporotic medication utilization following fragility fracture in the USA from 2011 to 2019

Summary: The purpose of this study was to determine whether there has been any change in osteoporosis treatment following primary fragility fractures and what agents were being given. The study found an overall low utilization rate with no difference in treatment utilization from 2011 to 2019. Purpose: The aim of this study is to describe trends in the utilization of anti-osteoporotic medication after fragility fracture, including changes in the specific types of medications prescribed. Methods: Patients older than 65 with fragility fractures sustained from 2011 to 2019 were identified in the PearlDiver Patient Records Database. Osteoporosis treatment rate was defined as the rate at which patients were prescribed any of the fourteen most used anti-osteoporotic medications within 1 year of fragility fracture. Fragility fractures were subcategorized by type. Treatment of fragility fractures was further stratified by patient demographics (age and gender) and medication type. Results: This study showed an overall osteoporosis treatment rate of 8.01%, with treatment rates of 6.87% following hip fractures, 6.71% following upper extremity fractures, and 14.38% following vertebral compression fractures (VCF). From 2011 to 2018, there was no change in the overall fragility fracture treatment rate (p = 0.32). Of the three fracture categories analyzed, only the treatment rate for VCFs increased (p = 0.048). Osteoporosis treatment in patients with VCF increased among patients 65–74 years old (p < 0.05) and male patients (p = 0.013). Treatment in patients with upper extremity fractures increased among patients 70–74 years old (p = 0.038). Bisphosphonates were the most frequently prescribed class of medications. Bisphosphonates and denosumab increased in utilization (p = 0.049 and p < 0.001 respectively) while calcitonin utilization decreased (p < 0.001). Conclusion: Besides the overall low utilization rate of osteoporosis treatment in patients following fragility fractures, there has been no change in the treatment utilization rate within the past decade. More resources and interventions need to be enforced for all providers managing these patients if we are ever to address the osteoporosis epidemic.
