Risk factors related to mortality at one year after surgery for intertrochanteric fracture in the elderly

Abstract

Objective To analyse risk factors related to mortality at one year after surgery for intertrochanteric fracture in the elderly. Methods Records of patients undergoing surgery at our hospital between January 2015 andJanuary2017 were retrospectively reviewed. By telephone follow up, the health condition of each patient was surveyed, and one year postoperative mortality was analyzed. The age, gender, fracture type, presence of chronic diseases at admission, time between fracture and surgery, and preoperative laboratory examination results were analyzed. Univariateand multivariate regression analyses were performed on relevant influencing factors. Results Complete data were available for a total of 161 patients who were followed up for 12-24 months (age≥60 years). There were 20 deaths (12.4%) at one year. Univariate analysis revealed that factors such as fracture type, chronic obstructive pulmonary disease, diabetes, number of preoperative diseases, preoperative albumin, and preoperative alanine amino transferase differed significantly between survival and death groups (P<0.05). Multivariate regression analysis revealed that chronic obstructive pulmonary disease, diabetes, and preoperative albumin were independent risk factors for death (P<0.05). Conclusions Taking full consideration of risk factors in the treatment of intertrochanteric fracture in the elderly, selecting appropriate anesthesia and treatment methods, improving preoperative health conditions may reduce the one-year mortality and facilitate functional recovery after surgery.
