Risk Factorsfor 1-Year Mortality in Elderly Patients after Hip Fracture Surgery

Abstract：Objective To observe the 1-year mortality after hip fracture surgery and summarize the death-associated risk factors .Methods 270 men and 549 women aged from 60 to 96 (mean ,76 .25 ± 7 .08) years old were followed up . The data of 819 elder patients who were over 60 years old with hip fracture and underwent surgical treatment in the af -filiated hospital of xuzhou medical university form January 2013 to December 2014 were collected and retrospectivelys-tudied .1-year mortality of patients was calculated .Death-associated risk factors were analyzed including age ,gender , number of preoperative systemic complications ,ASA grade ,surgical methodsand several indexes of hemotology .Univa-riate and binary logistic regression analysis were performed on relevant influencing factors .Results The 1-year mortali-ty of the 819 patients was 16 .97％ .Univariate analysis showed that the risk factorsof mortalitywere including age ,gen-der ,number of preoperative systemic complications ,ASA grade ,white blood cell count ,neutrophil-to-lymphocyte ratio , red cell distribution width ,platelet count ,total protein ,serum urea and serum creatinine on admission .Logistic regres-sion analysis revealed that the independent risk factorseffecting the mortality included age [P = 0 .000 ,OR = 1 .067 ,95％CI(1 .033 ～ 1 .102)] ,gender [P = 0 .046 ,OR = 0 .630 ,95％ CI(0 .390 ～ 1 .017)] ,number of preoperative systemic compli-cations [P = 0 .009 ,OR = 4 .757 ,95％ CI(1 .476 ～ 15 .350)] ,ASA grade [P = 0 .001 ,OR = 6 .127 ,95％ CI(2 .166 ～ 17 . 320)] ,red cell distribution widthat admission [P = 0 .017 ,OR = 1 .186 ,95％ CI(1 .031 ～ 1 .364)] ,serum ureaat admission [P = 0 .001 ,OR = 1 .175 ,95％ CI(1 .072 ～ 1 .288)] .Conclusion A number of factors was associated with mortality of hip fracture .age ,gender ,number of preoperative systemic complications ,ASA grade ,red cell distribution width and serum urea at admission were independent risk factors of 1-year mortality of elderly hip fracture .
