Virtual management of anticoagulant therapy for patients needing elective surgery

Official title: Perioperative Anticoagulant Use for Surgery Evaluation -Virtual Visit (PAUSE-Virtual), a Simple Perioperative Anticoagulant Management Approach, Replacing a Resource-intensive In-person Doctor-patient Consultation, With a Simple Virtual Care Model That Will Provide a New Standard of Care for Patients on a Direct Oral Anticoagulant or Warfarin and Require Elective Surgery/Procedure.

Run by McMaster University · NCT06844227 · Data updated 2026-11-12

This study is testing if virtual visits can safely manage blood thinner therapy for patients with atrial fibrillation who need elective surgery, instead of having them come in for in-person appointments.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older with atrial fibrillation who are on anticoagulant therapy and require elective surgery.

Probably not a fit

Patients whose anticoagulation is indicated for conditions other than atrial fibrillation or those with cognitive impairments may not benefit from this study.

What this trial studies

The PAUSE-Virtual study aims to evaluate the safety and effectiveness of managing anticoagulant therapy for patients with atrial fibrillation who require elective surgery through virtual visits instead of traditional in-person consultations. This observational study will assess whether virtual appointments can provide the same level of care and safety in terms of stroke and bleeding risks as in-person visits. Participants will receive guidance on when to stop and restart their blood thinners and instructions on self-administering short-acting anticoagulants if necessary. The study is particularly relevant in the context of changes in healthcare delivery due to the COVID-19 pandemic.

Why it matters

Potential benefit: If successful, this approach could streamline pre-surgery management for patients on blood thinners, making it more accessible and convenient.

How similar studies have gone: Previous studies have indicated that virtual care can be effective in managing various health conditions, suggesting potential success for this novel approach in anticoagulant management.

Inclusion Criteria:

* Age 18 years of age or older with AF/flutter (chronic, persistent, paroxysmal) that requires anticoagulation
* Receiving warfarin, with a target international normalized ratio (INR) range of 2.0-3.0, or a DOAC, comprising one of the following regimens: apixaban, 2.5 mg or 5 mg bid; edoxaban, 30 mg or 60 mg daily; dabigatran, 110 mg or 150 mg bid; or rivaroxaban, 15 mg or 20 mg daily
* Require an elective (planned, non-urgent) surgery or invasive medical or surgical procedure

Exclusion Criteria:

* Indication for anticoagulation is not AF/flutter (e.g., mechanical heart valve, VTE, other)
* Non-standard anticoagulant regimen used (e.g., warfarin INR 3-4, rivaroxaban 2.5 mg bid)
* In DOAC users only: creatinine clearance \<25 mL/min (that preclude DOAC use)
* Cognitive impairment or psychiatric illness (that precludes reliable contact during follow-up)
* Unable or unwilling to provide consent for virtual care (in-person care will be provided)
