OBJECTIVE: To evaluate the impact of a rivaroxaban discharge initiative on the efficacy and safety of acute venous thromboembolism treatment in emergency department patients.
PRACTICE INNOVATION: Patients discharged on rivaroxaban from the emergency department were provided extensive counseling along with a commercially-available medication dose pack by the ED pharmacist. Patients were contacted by phone until they had obtained outpatient follow-up and remained adherent to anticoagulation beyond the initial first month of treatment.
METHODS: In this retrospective chart review over a thirteen month period, efficacy and safety outcomes were compared between patients with intervention versus those who received usual care. Efficacy was defined by reduced 90-day readmission rates due to nonadherence or treatment failure, and improved medication adherence beyond the first month from discharge. Safety was determined by comparing 90-day readmission rates due to bleeding or adverse event.
RESULTS: 41 patients received intervention with rivaroxaban, and 34 patients received usual care, with 76% prescribed rivaroxaban and remaining patients started on enoxaparin alone (6%) or enoxaparin plus warfarin (18%). Improved treatment efficacy in the intervention group was not found to be statistically significant. Safety outcomes were similar between the two groups.
CONCLUSION: Home treatment of acute VTE, facilitated by medication dose pack, is a promising tactic to ensure both immediate and long-term treatment efficacy and safety. Further studies are warranted to demonstrate clinical superiority of this intervention.
