Among patients with negative inhospital duplex screening after total hip arthroplasty, only 1.5% developed symptomatic venous thromboembolic disease over 12 months without post-discharge prophylaxis.

Does inhospital duplex ultrasonography screening followed by no posthospitalization prophylaxis in negative patients safely prevent symptomatic venous thromboembolic disease in patients undergoing primary hybrid total hip arthroplasty?
Inhospital duplex ultrasonography screening after total hip arthroplasty identifies patients needing anticoagulation, while allowing the vast majority with negative screens to safely avoid posthospitalization prophylaxis.
Postoperative duplex ultrasonography screening after total hip arthroplasty has been shown to identify patients who may require treatment or additional monitoring for venous thromboembolic disease. The potential for manifestation of venous thromboembolic disease subsequent to screening remains a concern. The objective of this study was to determine the prevalence of symptomatic venous thromboembolic disease after total hip arthroplasty and after inhospital prophylaxis, inhospital screening with negative results for proximal deep venous thrombosis, and no posthospitalization venous thromboembolic disease prophylaxis. One hundred fifty patients undergoing primary hybrid total hip arthroplasty and using pneumatic compression stockings and aspirin as prophylaxis against venous thromboembolic disease were screened for deep venous thrombosis with duplex ultrasonography on the fourth day after surgery. Duplex ultrasonography screening revealed 17 (11.3%) patients with asymptomatic proximal deep venous thrombosis. In response to duplex ultrasonography screening, these patients with proximal deep venous thrombosis received therapeutic anticoagulation. Of 133 patients with a duplex screen with negative results for proximal deep venous thrombosis, 131 (98.5%) continued to have no symptoms of venous thromboembolic disease and two (1.5%) began to have symptoms for venous thromboembolic disease (one with proximal deep venous thrombosis, one with nonfatal pulmonary embolism) during 12 months of clinical followup after total hip arthroplasty. The overall prevalence of venous thromboembolic disease requiring anticoagulation was 19 of 150 (12.6%) patients. The remaining 131 (87.4%) were not exposed to the risks of postoperative anticoagulation and did not have subsequent symptomatic venous thromboembolic disease.
Beuhler et al. (1999) conducted a cohort in Venous thromboembolic disease after total hip arthroplasty (n=150). Inhospital duplex ultrasonography screening and no posthospitalization prophylaxis was evaluated on Symptomatic venous thromboembolic disease after negative duplex screening. Among patients with negative inhospital duplex screening after total hip arthroplasty, only 1.5% developed symptomatic venous thromboembolic disease over 12 months without post-discharge prophylaxis.
