Abstract
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 < 10 g/dL, arthroplasty and external fixator groups, ASA grade ≥ 3, delaying the surgery more than 4 days, longer hospitalization time, lower albumin levels and advanced age were found to be statistically significant factors for 3-month mortality (p values were; 0.01, 0.02, 0.01, 0.01, 0.047, 0.01, 0.02, 0.002, < 0.001, 0.002 and 0.01, respectively). Male gender, hypertension-neurologic-cardiac diseases, preoperative hemoglobin level < 10 g/dL, delaying the surgery more than 4 days, longer hospitalization time, lower lymphocyte percentage, lower albumin levels and advanced age were found to be statistically significant factors for 12-month mortality (p values were; < 0.001, 0.01, 0.01, 0.01, 0.03, 0.01, < 0.001, 0.01, 0.004 and < 0.001, respectively). CONCLUSION: COP, advanced age, and heart disease were the most important factors in 3-month mortality. Long hospitalization time, male gender and advanced age were the most important factors affecting the 12-month mortality.Level of Evidence Prognostic level IV.
