Key clinical point: Late initiation of antiosteoporosis medications (AOMs) is associated with a significantly increased risk of subsequent osteoporotic fracture-related hospitalizations compared with early initiation after an index hip fracture.
Major finding: Late initiation of AOMs (after 252 days) was associated with an increased risk of subsequent osteoporotic fracture-related hospitalization compared with early initiation (on or before 14 days) (hazard ratio [HR], 1.93; P = .001). Among patients with high adherence to AOMs, late initiation was associated with a significantly higher risk of fracture-related hospitalization compared with early initiation (HR, 2.56; P = .002).
Study details: A nationwide cohort study included 9,986 patients who were admitted to the hospital for hip fracture and were prescribed AOMs within 1 year of cohort entry date.
