目的：去处方是有计划和监督的剂量减少或停止用药的过程。很少有临床指南可以帮助医疗保健专业人员做出有关开处方的决定。Bruyère去处方指南小组制定了一系列基于证据的药物类别特定的去处方指南，为了扩大覆盖范围和吸收，将它们作为白板视频在YouTube上发布。本文报道了创作，质子泵抑制剂（PPI）视频的分享和评估，抗高血糖（AHG），抗精神病药（AP）和苯二氮卓受体激动剂（BZRA）处方指南。
方法：白板视频描绘了在白板上绘制的动画，而叙述者阅读脚本。在每个视频中，取消处方算法适用于模拟患者病例。这些视频在YouTube上分享，并通过Twitter和其他基于网络的工具进行推广。评估方法包括YouTube分析和经过验证的信息评估方法（IAM）问卷。
结果：四个视频在发布后的大约50个月内总共有26387次观看。观众平均观看34-40%的视频运行时间。PPI和AHG取消处方的视频在第一年在97个国家被观看了4318次。IAM受访者认为PPI，AHG和AP视频内容要相关，对学习有用，适用于病人护理。
结论：使用YouTube上的白板视频来解释开处方指南是一种成功的知识动员方法。评估方法具有创新性，因为它结合了在线学习视频的典型成功因素（例如，估计观看时间)，并对经过验证的信息评估工具做出回应。
OBJECTIVE: Deprescribing is the planned and supervised process of dose reduction or stopping medication. Few clinical
guidelines exist to help health care professionals in making decisions about deprescribing. The Bruyère Deprescribing
Guidelines Team developed a series of evidence-based medication-class specific deprescribing
guidelines and, to extend reach and uptake, disseminated them as whiteboard videos published on YouTube. This paper reports on the creation, sharing and evaluation of videos on proton pump inhibitor (PPI), antihyperglycemic (AHG), antipsychotic (AP) and benzodiazepine receptor agonist (BZRA) deprescribing
guidelines.
METHODS: Whiteboard videos depict an animator drawing on a whiteboard, while the narrator reads the script. In each video, the deprescribing algorithm is applied to mock patient cases. The videos were shared on YouTube and promoted via Twitter and other web-based tools. Evaluation methods included YouTube analytics and the validated Information Assessment Method (IAM) questionnaire.
RESULTS: The four videos have a combined total of 26 387 views over the approximately 50 months since publishing, with viewers watching 34-40% of the videos\' runtimes on average. The PPI and AHG deprescribing videos were viewed 4318 times in 97 countries during the first year. IAM respondents perceived the PPI, AHG and AP video content to be relevant, useful to learning and applicable to patient care.
CONCLUSIONS: Using whiteboard videos on YouTube to explain deprescribing
guidelines was a successful approach to knowledge mobilization. The evaluation approach is innovative as it combines typical success factors for online learning videos (e.g. views, estimated minutes watched) with responses to a validated information assessment tool.
