Thromboembolism Prophylaxis Efficacy in a Practice-Based Registry

Thromboembolism prophylaxis is both an important and vexing consideration for the arthroplasty surgeon. The American College of Chest Physicians (ACCP) guidelines led many surgeons to alter their previous strategy. Recently, the American Academy of Orthopaedic Surgeons (AAOS) work group published an alternate set of guidelines that incorporates assessment of risk. The AAHKS 2007 Rand Award Paper documented the efficacy of aspirin in the Medicare population (Bozic et al., AAHKS 2007). This is an observational cohort study examining the efficacy of thromboembolism prophylaxis in a dedicated arthroplasty practice.
