Perioperative Anticoagulant Use for Surgery Evaluation -2 (PAUSE-2) Study Patients Receiving a Direct Oral Anticoagulant (DOACs-Dabigatran, Rivaroxaban, Apixaban or Edoxaban) and Needing Elective High-Bleed-Risk Surgery or an Invasive Procedure
Recruiting now NCT06957366
Run by McMaster University · for 18 and older · All sexes
What this study is about
PAUSE 2 study is a prospective, open-label, blinded-endpoint non-inferiority RCT of PAUSE vs. ASRA management in DOAC treated high risk patients with AF/VTE who need elective high bleed risk surgery/procedure and/or any procedure involving neuraxial anesthesia. The purpose of the PAUSE 2 study is to show that PAUSE management will be as safe (i.e., non-inferior) as ASRA management, with 95% of patients having low/undetectable pre-operative DOAC levels \<30 ng/mL in each group., at the time of surgery/neuraxial.
Who can join (things the study team will check)
✅ You may be able to join if…
- Adults, age 18 years of age or greater, with AF/flutter (permanent, persistent or paroxysmal) or VTE (leg deep vein thrombosis or pulmonary embolism) that require a full (therapeutic)-dose DOAC regimen, appropriate for age and renal function, comprising one of (a) apixaban 2.5 mg or 5 mg bid; (b) dabigatran 110 mg or 150 mg bid; (c) edoxaban 30 mg or 60 mg daily; or (d) rivaroxaban 15 mg or 20 mg daily
- High-risk patient having an elective high-bleed-risk surgery or any elective surgery with neuraxial anesthesia (epidural, spinal, regional) or any deep nerve root block.
🚫 You may not be able to join if…
- Indication for anticoagulation is unusual site thrombosis (e.g. splanchnic, cerebral, sinus, arm)
- Receiving a low-dose DOAC regimen used for secondary VTE prevention (e.g. rivaroxaban 10 mg daily, apixaban 2.5 mg bid) or another low-dose DOAC regimen (e.g. rivaroxaban 2.5 mg bid)
- CrCL<25mL/min (if on apixaban, edoxaban, rivaroxaban) or <30 mL/min (if on dabigatran)
- cognitive impairment or psychiatric illness that precludes reliable contact during follow up.
