Tranexamic acid for reducing blood transfusions in arthroplasty interventions: a cost-effective practice.

Background: Tranexamic acid (TXA) administered during arthroplasty intervention can prevent blood loss and blood transfusions. The purpose of the present study is to evaluate the benefit of TXA administration on blood transfusion rates in patients undergoing joint arthroplasty, and to perform cost-benefit analysis.

Methods: The study population included 100 patients admitted for arthroplasty intervention between 1st June 2008 and 31st October 2008 who did not receive TXA, and 98 patients admitted between 1st June 2009 and 31st October 2009 receiving TXA during the intervention.
