ObjectiveTo study the effect of anti‐osteoporosis therapies on mortality after hip fracture.MethodsThis retrospective study was carried out in the Second Affiliated Hospital of Fujian Medical University and enrolled 690 patients 50 years of age and older who were admitted with hip fractures between 2010 and 2015. The patients were followed in 2017: 690 patients aged was from 50 to 103 years. There were 456 women and 234 men. There were 335 patients with fractures of the femoral neck and 355 patients with intertrochanteric fractures of the femur. There were 444 (64.35%) patients who also had internal diseases. The Charlson comorbidity index was 0–6. The anti‐osteoporosis medications were classified into no anti‐osteoporosis medication, calcium + vitamin D supplementations, non‐bisphosphonate medication, and bisphosphonate medication. The physicians followed the patients or family members by personal visit and telephone. Multivariable Cox regression analyses were done with known risk factors for mortality of hip fracture, such as gender, age, number of combined internal diseases, fracture type, place of residence, and Charlson comorbidity index, to show which anti‐osteoporosis medications had significant effects on mortality after adjustment for these variables.ResultsOut of 690 patients with hip fractures, 149 patients received no anti‐osteoporosis medication, 63 patients received calcium +vitamin D supplementations, 398 patients received non‐bisphosphonate medication, and 80 patients received bisphosphonate medication. The patients were followed between 7 months and 52 months, with the average of 28.53 ± 9.75 months. A total of 166 patients died during the follow‐up period. Of 166 deaths, 43 occurred within 3 months, 65 within 6 months, and 99 within 1 year after the hip fracture. In this study, fracture type, place of residence, and Charlson comorbidity index were not associated with the mortality, and the male gender, age > 75 years, and ≥ 2 combined internal diseases were the independent factors for deaths post‐hip fracture. The cumulative mortality was 36.24% in the patients receiving no anti‐osteoporosis medication. The hazard ratio for mortality after hip fracture with bisphosphonate medication, non‐bisphosphonate medication, and calcium/vitamin D supplementation was 0.355 (95% CI, 0.194–0.648), 0.492 (95% CI, 0.347–0.699) and 0.616 (95% CI, 0.341–1.114), respectively, as compared with no anti‐osteoporosis group. Bisphosphonate and non‐bisphosphonate medications for osteoporosis were significantly associated with the reduction of cumulative mortality post‐hip fracture (P < 0.01).ConclusionsBisphosphonate and non‐bisphosphonate medications for osteoporosis were significantly associated with decreased mortality after fragility hip fracture.
