[Objective] To analyze risk factors for death within one year after operation in elderly patients with femoral intertrochanteric fractures in two hospitals in southern Jiangsu. [Methods] A total of 864 femoral intertrochanteric fracture patients from August 2014 to January 2021 were retrospectively analyzed in two hospitals. The age, gender, hypertension, diabetes, stroke, cardiac diseases (including arrhythmia, coronary heart disease, etc.), pulmonary diseases (including pulmonary infection, COPD, asthma, etc.), time from injury to operation, length of stay, ASA grading, hemoglobin, albumin and total protein were analyzed to find risk factors for one year mortality after femoral intertrochanteric fracture surgery. [Results] Among the 864 patients, 144 died within one year after operation, and the mortality was 16.7%. The main cause of death was pulmonary infection. Cox regression analysis showed that age (HR = 4.587, P < 0.001), albumin (HR = 3.111, P = 0.017), lung disease (HR = 2.341, P = 0.042), length of hospital stay (HR = 3.436, P < 0.001) and ASA rating (HR = 3.377, P < 0.001) were the independent risk factors for one year mortality after femoral intertrochanteric fracture surgery in elderly patients. The best cut-off point of age for predicting the risk of death from the receiver operating characteristic (ROC) curve was 83.5 years (sensitivity 69.4%, specificity 82.8%). The best cut-off points of albumin level and hospital stay were 35.3g/L (sensitivity 88.9%, specificity 48.9%) and 18.5 days (sensitivity 72.2%, specificity 90.0%) by ROC curve analysis, respectively. [Conclusion] Old age, hypoalbuminemia, underlying lung diseases, prolonged hospital stay, and high ASA score (III, IV) are independent risk factors for death within one year after surgery for intertrochanteric fractures in the elderly over 65 years old in southern Jiangsu.
