Patient-Reported Treatment Experience with Oral Rivaroxaban: Results from the Noninterventional XALIA Study of Deep-Vein Thrombosis.

For venous thromboembolism (VTE) treatment, patient satisfaction was shown to improve with rivaroxaban versus standard anticoagulation in the phase III EINSTEIN DVT and EINSTEIN PE trials. This substudy of the prospective, noninterventional XALIA study of rivaroxaban for deep-vein thrombosis treatment assessed if this was also observed in routine clinical practice. Patients enrolled in XALIA who received rivaroxaban or standard anticoagulation treatment were eligible for inclusion in this substudy. Treatment decisions were at the physician's discretion. Patients completed the 17-item Anti-Clot Treatment Scale (ACTS, comprising a 12-item Burdens subscale, a 3-item Benefits subscale and one global item per subscale) during follow-up. The propensity score-matched set (PMS) was used for the main analysis; the adjusted safety analysis (ASAF) set was used for confirmatory purposes. Analyses by follow-up visit and subgroup, including age, sex, and previous VTE, were also conducted. The PMS-ACTS analysis included 458 rivaroxaban-treated and 434 standard anticoagulation-treated patients. Baseline demographic and clinical characteristics were generally similar across treatment arms. ACTS Burdens scores significantly improved with rivaroxaban versus standard anticoagulation (least-squares mean difference of 2.4 ± 0.4 points;
