Abstract
ABSTRACT: Venous thromboembolism (VTE) is a leading cause of mortality during the perioperative period, with individuals who have undergone hip and knee arthroplasty at the highest risk for VTE. The American College of Chest Physicians recommends 35 days of postoperative thromboprophylaxis and the use of intermittent pneumatic compression (IPC) therapy for mechanical compression after major orthopedic surgery. However, little research has described adherence to these recommendations during recovery at home. The purpose of this cross-sectional descriptive study was to describe thromboprophylaxis prescription, use, and education among patients discharged home after major orthopedic surgery. We surveyed patients within 2 years of major orthopedic surgery. A total of 388 subjects completed the survey. More than three-quarters of respondents reported a thromboprophylaxis duration <35 days. Most (93.8%) respondents were prescribed a pharmacologic agent, while 55.9% were prescribed mechanical compression therapy. Of the respondents who were prescribed mechanical compression therapy, 13.4% were prescribed IPC. Adherence to mechanical compression therapy was moderate, with 63% of respondents wearing mechanical compression therapy >=75% of the time. The results of this study suggest a need for increased duration of thromboprophylaxis and increased use of IPC in the outpatient setting. Additional research describing prescribers' perceptions of thromboprophylaxis is also needed.
