Objectives: The purpose of this study was to investigate the mortality rate and other associated risk factors a year after diagnosis of osteoporotic hip fracture.
Methods: A prospective cohort study was carried out in 120 patients who were at least 50 years of age who presented with a hip fracture caused by a simple fall and were admitted to Police General Hospital in 2013. Background data, mortality rate and associated risk factors were collected and evaluated.
Results: There were 88 females (73.33%) and 32 males (26.67%). The average age was 79.4 years. Eleven patients were deceased by the end of this study. The mortality rate was about 3.3 times higher when compared to the general population in the same age range (9.2% vs 2.28%). The survival rates for both sexes at 6 weeks, 6 months and 12 months after fracture were 94.2%, 93.3% and 90.8%, respectively. Higher mortality was associated with non-operative treatment only. Patients who were treated non-operatively had a 3.93 times higher mortality risk when compared to those who were treated operatively (23.8% vs 6.1%).
Conclusions: This study shows that the one-year mortality rate of osteoporotic hip fracture patients who were 50 years or older was 9%. However, the rate increased after an osteoporotic hip fracture, especially within the first year post-fracture. Higher mortality was associated with non-operative treatment only while the other variables were not.
