190 Patient Compliance with Aspirin and Rivaroxaban Post Elective Joint Replacement Surgery: A Quality Assurance Initiative

Introduction: Aspirin is a common, over the counter (OTC) medication. In conjunction with a five-day lead-in of Rivaroxaban, it is effective VTE prophylaxis for total knee (TKA) and hip (THA) arthroplasty (EPCAT II study). Aspirin may be thought of as a benign medication by patients given its non-prescriptive nature. Considering its role in VTE prophylaxis, it is important to ensure patient adherence to the full treatment regime [5 days Rivaroxaban then Aspirin 81 mg x 9 days (TKA) or x 30 days (THA)].
