Subsequent hip fractures in patients identified by a Fracture Liaison Service (FLS) in England and Wales – linkage of the national FLS and Hip Fracture databases

Abstract

AbstractFracture Liaison Services (FLSs) are recommended healthcare models to deliver secondary fracture prevention and reduce the risk of subsequent fractures. Several studies have demonstrated the cost and clinical effectiveness of FLSs, but there is little real-world data on the impact of FLSs on subsequent hip fracture rates.A cohort of 50,214 patients from the national FLS database with an index fracture of the hip, spine, or other in 2017 was linked to the National Hip Fracture Database from 2017 to 2020 to identify those patients who went on to have a subsequent hip fracture.One in twenty (5.1%) of the 9,888 people in whom the index fracture was at the hip went on to suffer a second hip fracture within 3-4 years, despite receiving the support of an FLS. The risk of hip fracture was similar (4.7%) if the index fracture was at the spine, but lower at other sites (2.8%, p<0.001) and the interval shortest after an index hip fracture (1.1 years (0.4,2.0) p<0.001). The proportion of patients with a subsequent hip fracture was not lower by types of anti-osteoporotic medication.This work highlights the need for alternative anti-osteoporotic management strategies to rapidly decrease the risk of subsequent hip fractures for people seen by an FLS setting with levels of risk that are even higher for patients in areas which are still not served by an FLS.
