To investigate whether a video tutorial, highlighting important aspects of keratoconus provided prior to a scheduled follow-up consultation, has a specific effect on patients' knowledge after the consultation.
Single center, randomized controlled trial registered on ISRCTN registry (number ISCTN75317089, https://doi.org/10.1186/ISRCTN75317089). Consenting eligible keratoconus patients were randomly assigned to either receive a conventional face-to-face consultation (control group) or to an additional video tutorial (interventional group) on definition, risk factors and treatment options provided prior to the consultation. The main outcome measure was the difference of knowledge assessed by a questionnaire after the consultation. Of each participant, clinical characteristics, highest educational level and medical background were obtained. We also performed a meta-analysis of published reports assessing knowledge improvement by video-based patient education.
We assigned 22 patients to the interventional and 21 patients to the control group. Mean age was 29.0 years (SD 11.6), 8/43 (18.6%) were female and median disease duration was 2.5 years (interquartile range: 2-5years). Compared to the control group, knowledge was 12.0% (95%CI: 5.8%-18.2%; p<0.001) higher in the interventional group. Subjects with a university degree scored 6.8% (95%CI: 3.8%-13.3%; p=0.038) higher. There was no interaction between video information and university degree. Other parameters were not associated with patient knowledge. The meta-analysis of 566 subjects enrolled in 6 studies revealed a standardized mean difference in favor of video-based education of 0.47 (95% CI: 0.30-0.64; p<0.004).
The results suggest that supplementary video information embedded in the clinical management of keratoconus, helps conveying relevant disease knowledge.
探讨在预定的随访咨询前提供的强调圆锥角膜重要方面的视频教程，在咨询后对患者知识水平是否有特定影响。
在ISRCTN注册中心注册的单中心随机对照试验（编号ISCTN75317089，https://doi.org/10.1186/ISRCTN75317089）。同意参与的合格圆锥角膜患者被随机分配，要么接受传统的面对面咨询（对照组），要么在咨询前接受关于圆锥角膜定义、风险因素和治疗选择的额外视频教程（干预组）。主要结局指标是咨询后通过问卷评估的知识差异。获取了每位参与者的临床特征、最高教育水平和医学背景。我们还对已发表的评估基于视频的患者教育对知识改善情况的报告进行了荟萃分析。
我们将22名患者分配到干预组，21名患者分配到对照组。平均年龄为29.0岁（标准差11.6），8/43（18.6%）为女性，疾病持续时间中位数为2.5年（四分位间距：2 - 5年）。与对照组相比，干预组的知识水平高12.0%（95%置信区间：5.8% - 18.2%；p<0.001）。拥有大学学位的受试者得分高6.8%（95%置信区间：3.8% - 13.3%；p = 0.038）。视频信息与大学学位之间没有交互作用。其他参数与患者知识无关。对6项研究中纳入的566名受试者进行的荟萃分析显示，支持基于视频教育的标准化平均差异为0.47（95%置信区间：0.30 - 0.64；p<0.004）。
结果表明，纳入圆锥角膜临床管理中的补充视频信息有助于传达相关疾病知识。
