Details and patient eligibility

About

Mechanisms by which to reduce exposure to allogeneic blood are of financial and clinical benefit in the hip fracture population. Tranexamic acid (TXA) is an inexpensive medication with low complication risk. Its use in the hip fracture population is unproven. The purpose of this study is to evaluate the efficacy and safety of topical tranexamic acid in reduction of peri-operative blood loss in hip fracture surgery.

Full description

The results of this study may dramatically alter the manner in which surgeons manage hip fracture patients in Canada. The use of topical TXA in operatively-treated hip fracture patients has the potential to reduce perioperative blood loss and consequently reduce exposure to allogeneic blood transfusion. This will positively influence post-operative morbidity and mortality, while at the same time substantially reduce hospital length of stay and overall health care costs. The proposed study is felt to have minimal risk, and is a relatively inexpensive study.

Update: An interim analysis was completed in January 2018. The Data Safety Monitoring Committee reviewed the results and recommend the trial continue as planned.

The final data analysis is in process. The abstract will be uploaded upon completion.
