Hip fracture contributes to long-, short-term excess mortality
Among elderly patients, hip fracture was considered a significant risk factor and contributed the most to long- and short-term excess mortality after comprehensive adjustment, according to study results.
Researchers recruited 217 elderly patients with hip fractures and 215 age- and sex-matched patients without fractures. D data on 55 covariates, including baseline details about health, function and bone mineral density, were recorded.
Using multivariate Cox proportional hazards model, the researchers analyzed hazard ratios of short- and long-term excess mortality for each covariate and calculated the population attributable risk proportion (PARP). Mean follow-up was 46.1 months.
Compared with non-fractured patients, a higher short-term mortality was seen in patients with hip fractures, and long-term excess mortality remained high. Hip fracture, comorbidities and lower Mini Mental State Examination were significant risk factors for short-term mortality, with PARP of 44.7% for hip fracture, 38.1% for comorbidities and 34.3% for lower Mini Mental State Examination.
The researchers also found hip fracture, lower T-score, lower body mass index, comorbidities, difficulty in activities of daily living and smoking were significant risk factors for long-term mortality.
