BACKGROUND: Little is known about the utilization of rivaroxaban in real life treatment settings in France.
AIMS: Objectives of this study were to describe the conditions of use and treatment persistence in patients with atrial fibrillation and treated with rivaroxaban for stroke prevention (SP-AF).
METHODS: A cohort study was performed using a representative sample of the French nationwide database. All adults who initiated rivaroxaban for SP-AF between 01/08/2012 and 31/12/2014 were included and followed for one year. Inappropriate use of rivaroxaban's was defined as use inconsistent with the summary of product characteristics.
RESULTS: In this study, 1278 patients were included, 687 (53.8%) were men and the mean age was 73.4years; 123 patients (9.6%) had a stroke and 78 (6.1%) a major bleeding event in the three years before rivaroxaban initiation. At treatment initiation 236 (18.5%) had chronic congestive heart failure, 991 (77.5%) hypertension, 247 (19.3%) diabetes and 9 (0.7%) HIV, hepatitis B or C infection. No anticoagulant had been administered in the six previous months for 777 patients (60.8%); 160 patients (12.5%) had an inappropriate use of rivaroxaban in SP-AF. At 6 and 12 months after the first delivery with rivaroxaban, 62.8%, and 51.7% (68.5% and 60.5% in sensitivity analyses) of the patients were still treated with rivaroxaban. The proportion of patients with a continuous medication availability above 80% was 96.1%.
CONCLUSION: The characteristics of patients in this study are similar to patients treated with this drug in other observational studies. Adherence and persistence with rivaroxaban can be considered good.
