BackgroundAn increasing number of elderly patients are managed with long-term antiplatelet therapy. Such patients often present with hip fracture requiring surgical intervention and may be at increased risk of perioperative bleeding and complications. The aim of this study was to ascertain whether it is necessary to stop clopidogrel preoperatively to avoid postoperative complications following hip hemiarthroplasty surgery in patients with intracapsular hip fracture.Materials And MethodsA retrospective review of 102 patients with intracapsular hip fracture with either perioperative clopidogrel therapy [clopidogrel group (CG)] or no previous clopidogrel exposure [no clopidogrel group (NCG)] who underwent hip hemiarthroplasty surgery was undertaken. Statistical comparison on pre- and postoperative haemoglobin, American Society of Anesthesiologists (ASA) grade, comorbidities, operative time, transfusion requirements, hospital length of stay (LOS), wound infection, haematoma and reoperation rate between the two groups was undertaken. Regression analysis was undertaken to ascertain the risk ratios (RR) of complications and transfusion associated with clopidogrel.ResultsThere was no difference with respect to ASA grade, comorbidities (except cardiac comorbidities), pre- and postoperative haemoglobin levels, operation time, age or gender between the two groups. Four and two patients, respectively, required transfusion postoperatively in the CG and NCG (p = 0.37). There was no difference with respect to LOS, wound infection, haematoma or reoperation rate between the two groups postoperatively. The covariate-adjusted RR for complications and transfusion while being on clopidogrel were 0.43 [95% confidence interval (CI) 0.07-2.60] and 3.96 (95% CI 0.40-39.68), respectively.ConclusionContinuing clopidogrel therapy throughout the perioperative period in patients with intracapsular hip fracture is not associated with an increased risk of complications following hip hemiarthroplasty surgery.
