Adverse events related to oral anticoagulants were the top reason for emergency room visits in the United States from 2013 to 2014. Most of these visits were associated with warfarin (85.7%), although apixaban, dabigatran, and rivaroxaban were implicated as well [1]. Internationally, rivaroxaban demonstrated a major and nonmajor bleeding rate of 1.5 and 10.7%, therefore patient education of adverse events is essential [2]. To improve education on anticoagulants, a toolkit was released by the Institute of Safe Medicine Practices in 2017. The toolkit contains 23 recommendations surrounding patient education, including ensuring an appropriate reading level for materials (6th grade) and specific recommendations on educational content. The toolkit mentions the use of supplemental tools, such as videos and handouts [3]. Video education has shown efficacy for many topics, including breast self-examinations, prostate cancer screening, and treatment adherence [4]. It can increase patients’ knowledge and satisfaction while decreasing health professionals time spent providing education [5]. In addition to videos, pictograms have been shown to improve medication comprehension, and are often used together [6]. Currently, a small number of studies have assessed warfarin educational videos [7–9]. One study evaluated knowledge gain in 15 patients after watching a warfarin education video. Patients’ knowledge of warfarin improved on a 12-question quiz from a score of 57.5% pre-video to 70% post-video, and 87% of patients were satisfied with the video [7]. In a study of warfarin education presented on an iPad, there was a 47% increase in knowledge from the preto post-test. There was no difference in satisfaction between healthcare provider and video education [8]. Currently there are no validated studies with publicly available rivaroxaban educational videos. Therefore, the purpose of this study was to evaluate the impact of rivaroxaban videos on improving patient knowledge and provide the videos for the public’s use.
