Effect of a Rivaroxaban Patient Assistance Kit (R-PAK) for Patients Discharged With Rivaroxaban: A Randomized Controlled Trial

Abstract

Background: The combination of poor health literacy and a complex dosing regimen/transition for rivaroxaban in venous thromboembolism (VTE) treatment may increase the likelihood of negative clinical outcomes secondary to nonadherence. Objective: The aim was to determine if a Rivaroxaban Patient Assistance Kit (R-PAK) given at hospital discharge increases proper dose transition and overall patient adherence. Methods: This prospective, randomized, controlled trial was conducted at an 859-bed academic medical center. Patients were randomized into 2 groups. In the treatment group, patients received the R-PAK with counseling at discharge, whereas patients in the control group received discharge counseling alone. In addition, patients were contacted after 21 days of therapy to assess dose transition, adherence, satisfaction, and safety. The primary outcome was percentage of patients who properly transitioned to rivaroxaban once daily on day 22. Results: Twenty-five patients were enrolled; 12 received an R-PAK, whereas 13 comprised the control group. No difference in the baseline assessment of health literacy status was noted (P = 1.00). Proper transition to daily administration on day 22 was no different between the groups (P = .891). Adherence was reported in 99.8% of R-PAK patients and 97.65% of control patients (P = .074). Side effects were rarely reported. Conclusions: The use of an R-PAK for the treatment of VTE was not associated with an improvement in transition to daily administration; however, both groups had high rates of overall adherence. Pharmacist counseling/education was provided in both groups and is an important component to include in any patient discharge, especially for medications with dose transitions.
