Official title

IMplementation of a Randomized Controlled Trial (RCT) to imProve Treatment With Oral AntiCoagulanTs in Patients With Atrial Fibrillation

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The purpose of this study is to use a decentralized claims database to determine whether education on stroke prevention in atrial fibrillation (AF) among AF patients and their providers can result in increased use of oral anticoagulants (OAC) for stroke prevention among those AF patients with guideline-based indications for oral anticoagulation (CHA₂DS₂-VASc score of 2 or greater). Specifically, the investigators will conduct a prospective, randomized, open-label education intervention trial to evaluate the effect of the early patient and provider education interventions on the proportion of patients with evidence of at least one OAC prescription fill (defined as one OAC dispensing or 4 international normalized ratio \[INR tests\] over the course of the follow-up through the date on which at least 80% of eligible study participants have at least 12 months of follow-up time). A total of approximately 80,000 patients will be enrolled within multiple major health plans across the United States. The randomization will be performed by the central coordinating center, and the health plans will mail the educational intervention materials to their members and providers.
