An Evaluation of Treatment Patterns for Osteoporosis and Outcomes After a Fragility Fracture in a Real-World Setting

Objectives:Treatment initiation and persistence after a fragility fracture are critical to reduce the risk of subsequent fractures. The authors evaluated osteoporosis management and outcomes after index fracture.Methods:This retrospective cohort study used real-world data for patients (>= 50 years), including pharmacy claims linked to commercial and Medicare medical claims from Symphony Health Patient Source. Osteoporosis management was evaluated for at least 12 months after the first case-qualifying fracture during the identification period and continued until a second fracture or March 31, 2020 (depending on data availability). Secondary fracture incidence was evaluated overall and for subgroups at very high risk.Results:Of 755,312 eligible patients, the proportion with a claim for bone mineral density testing at 12 months after index fracture was low [64,932 (8.6%)], and 75.3% of those tested were >= 65 years of age. Most patients (88.6%) remained untreated at any time after fracture. Among those treated, most (64.9%) were initially treated with bisphosphonates (oral, 93.7%; IV, 6.3%). Treatment duration and persistence were low for all treatments ranging from 6.5 months with 19.6% persistent for abaloparatide to 11.3 months with 45.0% persistent for denosumab. During follow-up, 13.6% of patients had a secondary fracture at any site, with higher incidence in subgroups considered to be at high risk for fracture than in the overall population.Conclusions:Low rates of osteoporosis testing and treatment initiation and high secondary fracture rates (particularly among patients at very high risk) highlight the need for better management of patients after a fracture.
