Abstract<\/h2>\n
Direct oral anticoagulants (DOACs) are increasingly being used due to their improved efficacy\/safety ratio and lower clinical and economic burden when compared to vitamin K antagonists. However, bleeding is still the most frequent complication associated with DOACs, and although rare, bleeding episodes can be life-threatening or critical. The impact of DOAC anticoagulation activity during a bleeding event must be evaluated according to patient clinical assessment, dosage and time from last intake, the presence of comorbidities (especially kidney and liver dysfunction), and, whenever possible, coagulation tests. Unfortunately, DOACs\u2019 anticoagulation activity is not easily or usually detectable in routine common coagulation testing. Specific DOAC tests allow for specific drug monitoring, but they are too time consuming, and are usually unavailable in routine emergency practice. If a clinically relevant DOAC plasma concentration is assumed or proven in a severe bleeding scenario, DOAC reversal is needed to restore hemostasis. This experts\u2019 consensus provides a narrative review about DOAC reversal and practical life-threatening bleeding management in several scenarios (trauma, intracranial hemorrhage and gastrointestinal bleeding), focusing on the selection of patients to whom specific reversal agents should be given.<\/div>\n

Key Points<\/strong><\/p><\/blockquote>\n

    \n
  1. DOACs Overview<\/strong>: Include FXa inhibitors (e.g., apixaban, rivaroxaban) and thrombin inhibitors (e.g., dabigatran), offering predictable anticoagulation effects and reduced routine monitoring needs.<\/li>\n
  2. Bleeding Risk<\/strong>: Life-threatening bleeding events remain a significant risk, with intracranial hemorrhage, gastrointestinal bleeding, and trauma-related bleeds being the most common.<\/li>\n
  3. Reversal Necessity<\/strong>: Urgent reversal is crucial in cases of critical bleeding, uncontrolled bleeding, or emergency surgeries.<\/li>\n
  4. Reversal Agents<\/strong>:\u00a0Idarucizumab<\/strong>: Reverses dabigatran rapidly and effectively.\u00a0Andexanet Alfa<\/strong>: Targets FXa inhibitors but is linked to thromboembolic risks.\u00a0Prothrombin Complex Concentrates (PCCs)<\/strong>: Used as nonspecific alternatives when specific agents are unavailable.<\/li>\n
  5. Pharmacokinetics<\/strong>: The effectiveness of reversal depends on the drug\u2019s half-life and renal clearance; impaired kidney function can prolong DOAC activity.<\/li>\n
  6. Diagnostic Tools<\/strong>: Tests like anti-FXa activity, DOAC-specific assays, and point-of-care (POC) DOAC dipstick tests are essential for evaluating anticoagulation levels.<\/li>\n
  7. Adverse Effects<\/strong>: Reversal agents carry risks, including thromboembolic events and potential drug rebound effects, requiring careful monitoring.<\/li>\n
  8. Guideline Recommendations<\/strong>: Specific reversal agents are preferred for critical bleeds, supported by major guidelines, while PCCs are recommended in their absence.<\/li>\n
  9. Algorithm for Management<\/strong>: A systematic approach involves stopping DOACs, supportive care, diagnostic assessments, and administering reversal agents based on the bleeding severity and agent availability.<\/li>\n
  10. Future Directions<\/strong>: Need for more randomized controlled trials to optimize reversal strategies and validate protocols in diverse clinical settings.<\/li>\n<\/ol>\n
