Management of Elevated INR (2.09) Before EGD

For a patient with an INR of 2.09 who needs an EGD tomorrow morning, no intervention is necessary as this INR is within the therapeutic range and acceptable for a low-risk endoscopic procedure. 1

Risk Assessment

  • EGD (esophagogastroduodenoscopy) is considered a low-risk endoscopic procedure when performed for diagnostic purposes with or without biopsy sampling 1
  • An INR of 2.09 falls within the therapeutic range (2.0-3.0) for most anticoagulation indications 1, 2
  • For low-risk endoscopic procedures, guidelines recommend proceeding with the procedure if the INR is within the therapeutic range 1

Management Recommendations

  • No need to withhold warfarin before the procedure as the INR is within therapeutic range 1
  • No vitamin K administration is necessary as the INR is not supratherapeutic 3, 4
  • The procedure can proceed as scheduled without delay 1

Special Considerations

  • If the EGD is planned for therapeutic intervention (such as polypectomy, EMR, or treatment of varices), it would be considered a high-risk procedure, and different management might be needed 1
  • For high-risk endoscopic procedures, an INR <1.5 is typically recommended, which would require temporary discontinuation of warfarin 1
  • The patient's thromboembolic risk should be considered when making decisions about anticoagulation management 1

Post-Procedure Management

  • Continue warfarin at the usual maintenance dose after the procedure 1, 2
  • Monitor for any signs of bleeding after the procedure 1, 2
  • If any bleeding occurs during or after the procedure, management should include local hemostatic measures 1

Common Pitfalls to Avoid

  • Unnecessarily withholding warfarin before low-risk procedures increases thromboembolic risk 1, 3
  • Administering vitamin K when not necessary can lead to warfarin resistance and difficulty re-establishing therapeutic anticoagulation 3, 4
  • Delaying necessary endoscopic procedures due to therapeutic INR levels is not supported by evidence 1, 5

Follow-up

  • Check INR within one week after the procedure to ensure it remains in the therapeutic range 1, 2
  • Identify and address any factors that may have contributed to the elevated INR (medication interactions, dietary changes, illness) 3, 2
