The effect of long-term antithrombotic therapies on perioperative morbidity and mortality in elderly patients undergoing hip fracture surgery

Abstract

ABSTRACT Objective: Ischemic complications or massive bleeding are important perioperative complications in elderly patients using antithrombotic drugs. The need for blood product replacement, transfusion-related complications, prolonged stay in hospital and intensive care unit, and high mortality in the perioperative period can be seen. The aim of this study was to investigate the effects of long-term different antithrombotic therapies on morbidity and mortality in elderly patients undergoing surgery for hip fracture. Materials and Methods: This retrospective cohort study included patients aged 65 years and older who underwent surgery for hip fracture between 2015 and 2018. Patients with no antithrombotic treatment (Group NonAT), warfarin (Group Warfarin), novel oral anticoagulants (Group NOACs), or dual antiplatelet therapy (Group DAPT) were compared in terms of major bleeding, deep venous thrombosis (DVT) and pulmonary thromboembolism (PTE) complications, length of hospital stay (LOS), ICU admission, and 30-day mortality. Results: The study included 668 patients; demographic data in Group NonAT (n=442), Group Warfarin (n=59), Group NOACs (n=30) and Group DAPT(n=137) were similar. Major bleeding and red blood cell transfusion did not differ statistically between all groups. (p>0.05) The preoperative and postoperative Hb values of the patients were not statistically different between the groups (p>0.05). Mortality, only there was statistically significantly higher in the dual antiplatelet group than the non user group. (p0.05) However survival was statistically significant different (p
