Design outcomes

Primary

MeasureTime frame
Main Objective: Objectives: To collect data on effect size for, and determine the feasibility of, a full scale multicentre RCT (Randomized Controlled Trial) that 1. compares the efficacy and safety of NOACs with VKA treatment according to Dutch standards, in VKA-experienced patients with currently well controlled VKA therapy, in the Dutch real-life setting 2. compares differences in treatment satisfaction, compliance and quality of life between NOACs and VKA treatment.;Primary end point(s): Main study parameters/endpoints: · Primary: net clinical benefit (stroke, major bleeds, systemic embolism, myocardial infarction, vascular death);Secondary Objective: Secondary: safety (major bleeds, clinically relevant non-major bleeds, all-cause mortality), efficacy (ischemic/unspecified stroke, systemic embolism, myocardial infarction, vascular death), burden of complications,;Timepoint(s) of evaluation of this end point: 12 months
