Four-Factor Prothrombin Complex Concentrate for the Reversal of Direct Oral Anticoagulants

Background: The prevalence of direct oral anticoagulants (DOACs) has increased with continued evidence of their efficacy and ease of use. However, the rise in their utilization also surfaced a concern regarding their reversal in patients actively bleeding and/or those requiring invasive procedures. Up until 2018, there were several reversal options available including 4-factor prothrombin complex concentrate (4-factor PCC), activated charcoal, desmopressin, and tranexamic acid. Then, in 2018, andexanet alpha, a recombinant factor Xa, was approved for the reversal of apixaban and rivaroxaban in patients with life-threatening or uncontrolled bleeding. Nonetheless, because 4-factor PCC is more easily attainable and cost-effective, it continues to be the more favorable option for many health-care professionals. Methods: This retrospective chart review was conducted at NYU Winthrop Hospital in patients who received 4-factor PCC for the reversal of DOACs from January 2018 to July 2018. Patient charts were reviewed and relevant data was collected (admitting diagnosis, dose of 4-factor PCC utilized, etc). Results: Fifty-three patients were evaluated with 85% experiencing a positive response and complete recovery following the administration of 4-factor PCC; 8 (15%) patients died after receiving 4-factor PCC, none as a result of its administration; 3 patients died secondary to other underlying comorbidities, 4 patients died due to an intracranial hemorrhage, and 1 died due to hematoma of the tongue. Conclusion: Based on the results thus far, the use of 4-factor PCC may be a good treatment option in patients requiring DOAC reversal.
