Abstract

Objectives: This study aims to investigate the incidence and risk factors for blood transfusion in patients undergoing simultaneous bilateral total hip arthroplasty (SimBTHA).

Patients and methods: Between January 2011 and June 2021, a total of 341 patients (289 males, 52 females; median age: 53 years; range, 43 to 66 years) who underwent SimBTHA were retrospectively analyzed. The patients were divided into two groups as those who did and did not require allogeneic blood transfusion. Univariate and multivariate logistic regression models were used to identify independent risk factors for transfusion.

Results: The incidence of transfusion in SimBTHA was 12.9%. We found that a higher preoperative hemoglobin level (odds ratio [OR]: 0.91; 95% confidence interval [CI]: 0.86-0.96), tranexamic acid (TXA) use (OR: 0.25; 95% CI: 0.09-0.58), and intraoperative autologous blood transfusion from a closed suction drainage system (OR: 0.30; 95% CI: 0.09-0.80) were protective against the need for transfusion in patients after SimBTHA. In addition, drainage use (OR: 3.52; 95% CI: 1.49-8.32) and intraoperative blood loss (OR: 1.17; 95% CI: 1.04-1.33) were the independent risk factors for blood transfusion.

Conclusion: The risk factors for transfusion after SimBTHA should be evaluated to establish specific, personalized transfusion risk assessments for each individual patient. For SimBTHA, the main risk factors include intraoperative bleeding and the use of drainage tube, while higher preoperative hemoglobin levels, TXA use, and autologous blood transfusion from a closed suction drainage system may reduce transfusion risk.
