Virtual management of anticoagulant therapy for patients needing elective surgery

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.

Observational McMaster University · NCT06844227

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.

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.

Who should consider this trial

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

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.

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 performed: 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.

Eligibility criteria

Show full inclusion / exclusion criteria
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)
* Previous participation in this study for an elective surgery/procedure
