Guideline for Holding DOACs Prior to Surgery
For elective surgery, stop DOACs 1 day before low-to-moderate bleeding risk procedures and 2 days before high bleeding risk procedures in patients with normal renal function, with no DOAC taken on the day of surgery. 1
Preoperative Management by Bleeding Risk
Low-to-Moderate Bleeding Risk Procedures
- Stop all DOACs (apixaban, rivaroxaban, edoxaban) 1 day before surgery (skip 2-3 doses depending on dosing frequency) 1
- Stop dabigatran 1-2 days before surgery if creatinine clearance (CrCl) ≥50 mL/min 1
- Examples include: cholecystectomy, inguinal hernia repair, colonoscopy with biopsy, arthroscopy 1, 2
- No DOAC should be taken on the day of surgery 1
High Bleeding Risk Procedures
- Stop apixaban, rivaroxaban, and edoxaban 2 days before surgery (skip 4-5 doses) 1, 3
- Stop dabigatran 2 days before surgery if CrCl ≥50 mL/min 1
- Examples include: cardiac surgery, intracranial/spinal surgery, major abdominal surgery, major cancer surgery, joint replacement 1, 4, 2
Very High Bleeding Risk Procedures
- For intracranial neurosurgery or neuraxial anesthesia/puncture, extend interruption up to 5 days for all DOACs in patients without renal failure 1
- Consider biological monitoring of DOAC levels if needed 1
Special Considerations for Renal Impairment
Dabigatran (80% renal clearance)
- CrCl 30-50 mL/min: Stop 3-4 days before high bleeding risk surgery 1, 5
- CrCl <30 mL/min: Stop 4-5 days before surgery 1, 5
- Dabigatran requires the longest interruption due to predominant renal elimination 1
Factor Xa Inhibitors (Apixaban, Rivaroxaban, Edoxaban)
- CrCl ≥50 mL/min: Standard interruption times apply 1
- CrCl 30-50 mL/min: Consider extending interruption by 1 additional day 1
- Apixaban has only 25% renal clearance, making it less dependent on kidney function 4, 2
Additional Risk Factors Requiring Longer Interruption
Extend DOAC interruption in patients with: 1
- Severely impaired renal function (CrCl <30 mL/min)
- Severely impaired hepatic function
- Concomitant use of P-glycoprotein inhibitors (affects all DOACs)
- Concomitant use of CYP3A4 inhibitors (affects apixaban, rivaroxaban, edoxaban)
- Age >80 years (particularly for dabigatran) 1
Bridging Anticoagulation
Preoperative bridging with heparin or low-molecular-weight heparin is NOT recommended for routine DOAC interruption 1, 2
- The rapid offset of DOACs eliminates the need for bridging 4
- Bridging may only be considered in very high thrombotic risk patients 1
Postoperative Resumption
Low-to-Moderate Bleeding Risk
- Resume DOACs 1 day after surgery (24 hours postoperatively) at usual dose 1
- Ensure adequate hemostasis before resumption 1, 3
High Bleeding Risk
- Resume DOACs 2-3 days after surgery (48-72 hours postoperatively) 1, 4, 2
- Consider reduced dose (e.g., apixaban 2.5 mg twice daily) for first 2-3 days in high thrombotic risk patients 4, 2
- May use prophylactic LMWH starting 6 hours postoperatively until therapeutic DOAC resumed 1
Laboratory Monitoring
Routine coagulation testing (INR, aPTT) is NOT required when recommended interruption periods are followed 1
Consider DOAC-specific testing in urgent surgery (<24 hours): 1, 4
- DOAC-calibrated anti-factor Xa levels for apixaban, rivaroxaban, edoxaban
- Dilute thrombin time or ecarin clotting time for dabigatran
- Standard PT/aPTT may be insensitive to residual DOAC effect 1, 4
Critical Pitfalls to Avoid
- Never perform neuraxial anesthesia with possible residual DOAC concentration, especially in dabigatran patients >80 years or with renal impairment 1
- Do not double the dose to make up for a missed preoperative dose 3, 5
- Verify recent creatinine clearance before determining interruption timing, as renal function affects clearance 1
- Check for drug interactions with P-glycoprotein or CYP3A4 inhibitors that may prolong DOAC effect 1
- Ensure at least 6 hours elapsed before any postoperative DOAC resumption 1
