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

Plain-language summary

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.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion Criteria: * 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. Exclusion Criteria: * 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. * Unable or unwilling to provide consent * Previous participation in PAUSE 2

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
