Although several patient education materials on colonoscopy preparation exist, few studies have evaluated or compared them; hence, there is no professional consensus on recommended content or media to use.
This study aims to address this need by developing and evaluating a new video on colonoscopy preparation.
We developed a new video explaining split-dose bowel preparation for colonoscopy. Of similar content videos on the internet (n=20), the most favorably reviewed video among patient and physician advisers was used as the comparator for the study. A total of 232 individuals attending gastroenterology or urology clinics reviewed the new and comparator videos. The order of administration of the new and comparator videos was randomly counterbalanced to assess the impact of presentation order. Respondents rated each video on the following dimensions: information amount, clarity, trustworthiness, understandability, new or familiar information, reassurance, information learned, understanding from the patient's point of view, appeal, and the likelihood of recommending the video to others.
Overall, 71.6% (166/232) of the participants preferred the new video, 25.0% (58/232) preferred the comparator video, and 3.4% (8/232) were not sure. Furthermore, 64.0% (71/111) of those who viewed the new video first preferred it, whereas 77.7% (94/121) of the participants who viewed the new video second preferred it. Multivariable logistic regression analysis also demonstrated that participants were more likely to prefer the new video if they had viewed it second. Participants who preferred the new video rated it as clearer and more trustworthy than those who preferred the comparator video.
This study developed and assessed the strengths of a newly developed colonoscopy educational video.
尽管有几种关于结肠镜检查准备的患者教育材料，但很少有研究对其进行评估或比较；因此，对于推荐的内容或使用的媒介，尚无专业共识。
本研究旨在通过制作和评估一部关于结肠镜检查准备的新视频来满足这一需求。
我们制作了一部新视频，解释结肠镜检查的分剂量肠道准备。在互联网上搜索到的内容相似的视频（n = 20）中，患者和医生顾问评价最高的视频被用作本研究的对照视频。共有232名到胃肠病科或泌尿科诊所就诊的患者观看了新视频和对照视频。新视频和对照视频的播放顺序进行随机平衡，以评估播放顺序的影响。受访者从以下几个维度对每个视频进行评分：信息量、清晰度、可信度、可理解性、新信息或熟悉信息、安心程度、学到的信息、从患者角度的理解、吸引力以及向他人推荐该视频的可能性。
总体而言，71.6%（166/232）的参与者更喜欢新视频，25.0%（58/232）更喜欢对照视频，3.4%（8/232）不确定。此外，先观看新视频的参与者中有64.0%（71/111）更喜欢它，而第二次观看新视频的参与者中有77.7%（94/121）更喜欢它。多变量逻辑回归分析还表明，第二次观看新视频的参与者更有可能更喜欢它。与更喜欢对照视频的参与者相比，更喜欢新视频的参与者认为它更清晰、更可信。
本研究制作并评估了一部新的结肠镜检查教育视频的优点。
