Perioperative Management of Anticoagulation
Margaret C. Fang, MD, MPH
Current estimates indicate that 2 to 3 million Americans take anticoagulants for prevention of thromboembolism from venous thromboembolism, atrial fibrillation, or prosthetic heart valves. Invasive procedures are performed in as many as 250 000 patients taking anticoagulants on an annual basis in the United States. Consequently, management of anticoagulants in the perioperative period is a common and vexing challenge for physicians. Because not all patients are at the same risk of thromboembolism and not all procedures are associated with the same risk of bleeding, it is important for hospitalists to know how to weigh these risks in their patients. The purpose of this module is to review risk stratification for thromboembolism and bleeding associated with different thromboembolic disorders and invasive procedures.
To provide hospitalists with current evidence on recommended management of anticoagulants in the periprocedural period.
This activity is designed for hospitalists.
After completing the module, the participant should be able to:
- Assess the risk of venous thromboembolism (VTE) associated with interruption of anticoagulation in patients with a history of VTE, deep venous thrombosis, or pulmonary embolism.
- Assess the risk of arterial thromboembolism (ATE) associated with interruption of anticoagulation in patients with atrial fibrillation.
- Assess the risk of ATE associated with interruption of anticoagulation in patients with mechanical heart valves.
- Formulate a plan for preoperative management of patients taking warfarin that accounts for bleeding and thrombotic risk.
- Propose a plan for postoperative management of anticoagulation taking into account bleeding and thrombotic risk.
- Develop a perioperative management plan for patients taking a target-specific oral anticoagulant.
This activity has been planned and implemented in accordance with the accreditation requirements and policies of the Accreditation Council for Continuing Medical Education (ACCME) through the joint providership of University of Virginia School of Medicine, ASiM, and the Society of Hospital Medicine. The University of Virginia School of Medicine is accredited by the ACCME to provide continuing medical education for physicians.
The University of Virginia School of Medicine designates this enduring material, journal-based CME activity, test item writing activity for a maximum of 2.0 AMA PRA Category 1 Credits.TM Physicians should claim only the credit commensurate with the extent of their participation in the activity.
