Mohs Micrographic Surgery: Key Pharmacologic Considerations.

Abstract

To describe Mohs micrographic surgery and evaluate whether direct oral anticoagulants should be withheld in patients with atrial fibrillation (Afib) prior to the procedure and to consider what type of antibiotic prophylaxis should be used. A community setting in which an elderly patient is living independently at home. Academic-affiliated internal medicine clinic that cares for adult patients of all ages, including elderly patients living independently in their own home. The practice occasionally consults with geriatric specialty pharmacists to obtain drug information regarding drug therapy. Identify and assess literature regarding therapeutic issues regarding patients with Afib, whether direct oral anticoagulants should be withheld prior to dermatologic surgery, and what type of antibiotic prophylaxis should be provided prior to the procedure. Highlight literature that assesses surgical bleeding risk if direct oral anticoagulants are continued, and alternatively, the risk of a thromboembolic event if discontinued; and address antibiotic prophylaxis prior to Mohs micrographic surgery in a patient with Afib. In an elderly patient with Afib, a pharmacist should evaluate bleeding risk if direct oral anticoagulants are continued, risk for stroke if anticoagulants are discontinued, and determine appropriate antibiotic prophylaxis prior to Mohs micrographic surgery. In patients with Afib treated with direct oral anticoagulants who will have dermatologic surgery, the bleeding risk is usually low, whereas risk of a possible thromboembolic event is high, and antibiotic prophylaxis should be done to prevent infection.
