Abstract
Introduction:
Mortality after a hip fracture increases compared to the general population. The main objective of this study is to examine the incidence, trends, and factors associated with mortality in patients with osteoporotic hip fractures.
Methods:
This is a retrospective cohort study from a South American hospital. Patients older than 65 years with osteoporotic hip fracture between 2015 and 2018 were identified. Demographic data and comorbidities were obtained. The incidence rate, standardized mortality rate, trend (Poisson regression), and risk (hazard ratio) were calculated.
Results:
A total of 304 patients admitted for osteoporotic hip fracture were found, 240 (79%) were women with a mean age of 81.3 years (SD 8.45) and 64 (22.1%) were men with a mean age of 85. .42 years (SD 10.08). The cumulative incidence of mortality was 72.5%. The annual mortality rate was 75.6/1000 patients/year (54.8 in men and 20.8 in women). The 1-year mortality rate increased significantly by 2% per year (HR 1.05, 95% CI 1.002–1.08). Median overall survival was 854 days (95%CI 802-906). The mortality probability density was 18% for women and 27% for men (first 90 days).
Conclusions:
A more significant increase in mortality was observed in men than in women. Institutionalization combined with comorbidities are associated with higher mortality.
