Conclusions
The findings of this randomized clinical trial suggest that clinician-created educational videos could present a low-cost approach to augment patient-centered cardiovascular care. In this study, short clinician-created, patient-targeted educational videos offered weekly via email improved AF knowledge at 3 months after routine outpatient care. Highly engaged patients were more likely to correctly answer AF knowledge questions. An effect on medication adherence was not identified in this trial but should be investigated in larger studies. This study did not measure any cardiovascular outcomes, but this could be a logical progression of the concept.
