Risk Factors for Recurrent Fractures in Hip Fracture Patients: A Big Data Analysis of Demographic, Clinical, and...

Background/Objectives: Individuals who have sustained a hip fracture are at an increased risk of experiencing a recurrent fracture. The issue of recurrent fractures in post-acute settings has been scarcely studied. Our aim was to identify independent predictors associated with fracture recurrence. Methods: Data were extracted from the Clalit Health Services Research Data Sharing Platform, powered by MDClone. Chi-square and t-tests compared categorical and continuous variables between the two patient groups. Logistic regression analysis was used to identify independent predictors of recurrent fractures following hip fracture. Results: The study population comprised 40,391 Clalit Health Services insured patients aged ≥ 65 years who had sustained a hip fracture between the years 2016 and 2023; 23,027 (57%) sustained a single hip fracture during the study period; 17,364 (43%) experienced a recurrent fracture. Independent predictors of recurrent fractures included a documented diagnosis of osteoporosis at the time of the first fracture and a history of cerebrovascular disease, depression, and female gender. Conclusions: These findings underscore the multifactorial nature of recurrent fracture risk in older adults following an initial hip fracture. Proactive identification of patients with these risk factors and the implementation of targeted secondary prevention strategies may reduce the incidence of subsequent fractures.
