Abstract 14379: Implementation of Pharmacist-led Antithrombotic Medication Management for Elective Endoscopic Procedures

Introduction: Mismanagement of antithrombotic medications often leads to cancelled elective procedures. Pharmacist-led anticoagulation management prior to elective procedures is not well studied. Methods: We implemented a best practice advisory (BPA) that offered referral to a pharmacist-led medication management service prior to elective outpatient gastrointestinal endoscopies. Eligible patients were taking warfarin, a direct oral anticoagulant, and/or a P2Y12 inhibitor for management of atrial fibrillation (AF), venous thromboembolism (VTE), coronary artery disease (CAD), peripheral arterial disease (PAD), and/or mechanical heart valve. Patients referred to the antithrombotic service were compared to those managed by the ordering provider. Outcomes assessed included documentation of a medication management plan, guideline-appropriateness of drug cessation prior to endoscopy, and guideline-appropriate rates of enoxaparin bridging for high risk warfarin patients. Results: Seventy-four percent of patients (448/645) were referred to the antithrombotic service. These patients were more likely to have had VTE (33.0% vs. 18.2%), less likely to have CAD (31.9% vs. 40.9%; p=0.009 for indication category), and more likely to be prescribed warfarin (32.8% vs 20.9%, p Conclusion: Pre-procedural antithrombotic medication management by a pharmacist-led team for elective endoscopies was associated with more guideline-adherent management and better documentation of the medication plans.
