Study description

The research question is to assess the one-year and two-year benefit-risk of rivaroxaban for stroke prevention in atrial fibrillation (SPAF) compared to vitamin K antagonists (VKA) and dabigatran among new anticoagulant users. The main objective is to compare the one-year and two-year risk of the following individual outcomes: stroke and systemic embolism (SSE), major bleeding and death, between new users of anticoagulant for SPAF during drug exposure: rivaroxaban versus VKA, and rivaroxaban versus dabigatran (standard and reduced doses). Secondary outcomes were clinically relevant bleeding (CRB), acute coronary syndrome (ACS) and a composite criterion of SSE, major bleeding or death. This is a cohort study in the French national healthcare claims and hospitalisation database (SNDS, Système National des Données de Santé) including new users of rivaroxaban, dabigatran, or VKA for SPAF with a follow-up for at least one year and up to two years per subject, and three-year history. The index date will be that of the first dispensation of rivaroxaban, dabigatran, or VKA in 2013 or 2014. Data will be extracted from 2010 to 2015. Outcomes analysis will be performed during drug exposure for matched patients on high-dimensional propensity score (hdPS), and all patients with hdPS adjustment.
