Study description

The research question is to assess the baseline short-term, medium-term and long-term benefit-risk of vitamin K antagonists (VKA) for new users in the indication of atrial fibrillation (AF). The main objective is to estimate the 6-month, 1-year, and 3-year risk of major bleeding, arterial thrombotic events (stroke, systemic embolism), myocardial infarction (MI) and death during VKA exposure. This is a cohort study in a national healthcare claims and hospitalisations database including new users of VKA for AF between 01/01/2007 and 31/12/2011 with a follow-up until 31/12/2012, and 2 years history. VKA exposure will start at the date of first VKA dispensation (index date) and end at the date of VKA stop or at the end of follow-up. AF population will be defined as patients with full coverage for AF, hospitalisation or probabilistic AF information in the database, and without other probable cause of VKA prescription. Outcomes will be defined by primary diagnosis ICD-10 codes of hospital-discharge summary and date of death. The cumulative incidence of outcomes will be estimated using Kaplan-Meier estimate and 95% confidence interval.
