Supplemental Table: Video breakdown of 1,895 NeuroByte user satisfaction survey responses

Objective To determine whether NeuroBytes is a helpful e-Learning tool in neurology through usage, viewer type, estimated time and cost of development, and post-course survey responses. Background A sustainable continuing professional development (CPD) system is vital in neurology due to the field’s expanding therapeutic options and vulnerable patient populations. In an effort to offer concise, evidence based updates to a wide range of neurology professionals, the AAN launched NeuroBytes in 2018. NeuroBytes are brief (<5 min) videos that provide high-yield updates to AAN members. Methods NeuroBytes was beta tested from August–December 2018 and launched for pilot circulation from January–April 2019. Usage was assessed by quantifying course enrollment and completion rates; feasibility by cost and time required to design and release a module; appeal by user satisfaction; and impact by self-reported change in practice. Results A total of 5,130 NeuroBytes enrollments (1,026±551/month) occurred from January 11–May 28, 2019 with a median of 588 enrollments per module (interquartile range, 194-922) and 37% course completion. The majority of viewers were neurologists (54%), neurologists in training (26%), and students (8%). NeuroBytes took 59 hours to develop at an estimated $77.94/hour. Of the 1,895 users who completed the survey, 82% were “extremely” or “very likely” to recommend NeuroBytes to a colleague and 60% agreed that the depth of educational content was “just right.” Conclusions NeuroBytes is a user-friendly, easily accessible CPD product that delivers concise updates to a broad range of neurology practitioners and trainees. Future efforts will explore models where NeuroBytes combines with other CPD programs to impact quality of training and clinical practice.一、研究目的：本研究旨在通过使用情况、受众类型、开发预估时长与成本，以及课后问卷反馈，评估NeuroBytes是否为一款实用的神经病学电子学习（e-Learning）工具。 二、研究背景：鉴于神经病学领域治疗手段不断拓展且患者群体较为脆弱，可持续的继续职业发展（Continuing Professional Development，以下简称CPD）体系对于该领域而言至关重要。为向广大神经病学专业人员提供简洁且基于证据的学科进展更新，美国神经病学学会（American Academy of Neurology，简称AAN）于2018年推出了NeuroBytes。NeuroBytes为时长不足5分钟的短视频，可为AAN会员提供高价值的学科进展资讯。 三、研究方法：NeuroBytes于2018年8月至12月完成β测试，并于2019年1月至4月启动试点推广。本研究通过量化课程注册与完成率评估其使用情况；以模块设计与发布所需的成本与时长评估其可行性；以用户满意度评估其受欢迎程度；以受试者自我报告的临床实践变化评估其应用影响。 四、研究结果：2019年1月11日至5月28日期间，NeuroBytes累计注册量达5130人次，月均注册量为1026±551人次；单模块注册量中位数为588人次（四分位距194~922），课程完成率为37%。受众群体中占比最高的为神经科医师（54%）、受训神经科医师（26%）以及医学生（8%）。开发单条NeuroBytes模块共计耗时59小时，预估每小时成本为77.94美元。在完成问卷的1895名用户中，82%的受访者表示"极其有可能"或"非常有可能"向同行推荐NeuroBytes，另有60%的受访者认为其教育内容的深度"恰到好处"。 五、研究结论：NeuroBytes是一款操作便捷、易于获取的CPD产品，可为广大神经病学从业者与受训人员提供简洁实用的学科进展资讯。未来研究将探索将NeuroBytes与其他CPD项目相结合的模式，以提升培训质量与临床实践水平。
