Video animations are used increasingly as patient information tools; however, we do not know their value compared to other formats of delivery, such as printed materials, verbal consultations or static images.
This review compares the effectiveness of video animations as information tools vs. other formats of delivery on patient knowledge, attitudes and cognitions, and behaviours. Included studies had the following features: controlled design with random or quasi-random allocation; patients being informed about any health condition or members of the public being informed about a public health topic; comparing video animation with another delivery format. Multiple digital databases were searched from 1996-June 2021. We also undertook citation searching. We used dual, independent decision-making for inclusion assessment, data extraction and quality appraisal. Included studies were appraised using the Cochrane ROB2 tool. Findings were reported using narrative synthesis.
We included 38 trials, focussed on: explaining medical or surgical procedures ( = 17); management of long-term conditions ( = 11); public health, health-promotion or illness-prevention ( = 10). Studies evaluated cartoon animations ( = 29), 3D animations ( = 6), or 2D animations, "white-board" animations or avatars ( = 1 each). Knowledge was assessed in 30 studies, showing greater knowledge from animations in 19 studies, compared to a range of comparators. Attitudes and cognitions were assessed in 21 studies, and animations resulted in positive outcomes in six studies, null effects in 14 studies, and less positive outcomes than standard care in one study. Patient behaviours were assessed in nine studies, with animations resulting in positive outcomes in four and null effects in the remainder. Overall risk of bias was "high" ( = 18), "some concerns" ( = 16) or "low" ( = 4). Common reasons for increased risk of bias were randomisation processes, small sample size or lack of sample size calculation, missing outcome data, and lack of protocol publication.
The overall evidence base is highly variable, with mostly small trials. Video animations show promise as patient information tools, particularly for effects on knowledge, but further evaluation is needed in higher quality studies.

视频动画越来越多地被用作患者信息工具；然而，与其他传递形式（如印刷材料、口头咨询或静态图像）相比，我们并不清楚其价值。
本综述比较了视频动画作为信息工具与其他传递形式在患者知识、态度、认知及行为方面的有效性。纳入的研究具有以下特点：采用随机或准随机分配的对照设计；患者了解任何健康状况或公众了解公共卫生主题；将视频动画与另一种传递形式进行比较。检索了1996年至2021年6月的多个数字数据库。我们还进行了引文检索。我们采用双重独立决策进行纳入评估、数据提取和质量评估。使用Cochrane ROB2工具对纳入的研究进行评估。研究结果采用叙述性综合报告。
我们纳入了38项试验，重点关注：解释医疗或外科手术（17项）；慢性病管理（11项）；公共卫生、健康促进或疾病预防（10项）。研究评估了卡通动画（29项）、3D动画（6项）或2D动画、“白板”动画或虚拟化身（各1项）。30项研究评估了知识，与一系列对照相比，19项研究显示动画能带来更多知识。21项研究评估了态度和认知，6项研究中动画产生了积极结果，14项研究中无效果，1项研究中动画产生的积极结果少于标准护理。9项研究评估了患者行为，4项研究中动画产生了积极结果，其余研究中无效果。总体偏倚风险为“高”（18项）、“有些担忧”（16项）或“低”（4项）。偏倚风险增加的常见原因是随机化过程、样本量小或缺乏样本量计算、结局数据缺失以及缺乏方案发表。
总体证据基础差异很大，大多是小型试验。视频动画作为患者信息工具显示出前景，尤其是对知识的影响，但需要在更高质量的研究中进行进一步评估。
