Analysis of Factors Affecting the Third- and Twelfth-Month Mortality in Patients with Hip Fractures Aged 80 Years and Older

Background The purpose of this study was to evaluate the possible risk factors that are related with mortality at third and twelfth months after hip fractures in a large population of patients aged 80 years and older. Methods 605 patients were evaluated in terms of the localization of the fracture, gender, age, side of the fracture, the type of applied procedure, anesthesia type, hospitalization time, time to operation, comorbidities, ASA score, the values of preoperative hemoglobin, lymphocyte and neutrophil percentage, white blood cell, albumin, sodium levels. The state mortality system was used to investigate whether patients are alive or died. Statistical analysis was performed to evaluate the important factors on third- and twelfth-month mortality. Results Male gender, neurologic–cardiac–chronic obstructive pulmonary (COP) diseases, preoperative hemoglobin level
