BackgroundDisability and death following hip fracture is becoming more common as the population ages. Previous reports have focused on the selection of internal fixation methods and the analysis of the perioperative therapeutic results in the Chinese population. Few studies have focused on factors influencing medium and long term survival after surgery for hip fracture. We conducted a retrospective study on the factors influencing survival one year after hip fracture surgery in our elderly Chinese population to provide a reference for improved treatment and to enhance efficacy.MethodsRecords from patients undergoing treatment for hip fracture at our hospital from October 2009 through June 2011 were retrospectively reviewed. Through telephone follow-up, the health condition of each patient was surveyed, and the 1-year postoperative mortality was analyzed. The patients' age, gender, fracture type, pre-injury health condition, mobility, complications, surgical timing, surgical types, methods of anesthesia, and postoperative complications were analyzed. Univariate and multivariate regression analysis was performed on relevant influencing factors.ResultsA total of 184 patients had complete data and were followed-up for 12-23 months (average, 16.5 months). There were 30 deaths (16.3%) at one-year. Univariate analysis revealed that factors such as age, gender, fracture-type, number of co-existing diseases, complications such as chronic obstructive pulmonary disease or sequelae of stroke, American society of Anesthesiology (ASA) scores, anesthesia methods, pre-injury activity, and post-operative complications were significantly different between survival versus mortality groups (P < 0.05). Multivariate regression analysis revealed that age, ASA score, pre-injury mobility and combined chronic obstructive pulmonary disease were independent risk factors for death.ConclusionFull consideration of medium-/long-term risk factors in the treatment of hip fracture in the elderly, selection of appropriate anesthesia and treatment methods, and improved pre-surgical health conditions would reduce postoperative mortality and enhance surgical efficacy.
