进行了一项随机对照试验，以确定由医生录制的演示是否比由同一医生使用相同脚本的面对面讨论更有效地传达信息。201名接受结肠镜检查的患者参加了这项研究。患者被随机分配到三组中的一组：视频+讨论组、单独视频组和单独讨论组。所有患者都接受了有效的13个项目的知识测试和状态-特质焦虑问卷。视频+讨论的平均正确答案数为11.04；视频+讨论的平均正确答案数为10.70；单独讨论的平均正确答案数为9.61。方差分析和计划的正交比较显示，两个视频组的患者得分显著高于仅讨论组的患者(p<；0.001)。两个视频组之间没有差异(p=0.32)。焦虑并没有随着对结肠镜检查风险和益处的了解的增加而增加。这种方法可能也适用于其他侵入性医疗程序，可以节省医生的时间，同时为更个性化的讨论奠定基础。
A randomized controlled trial was conducted to determine if a videotaped presentation by a physician conveys information more effectively than an in-person discussion by the same physician using the identical script. Two hundred one patients undergoing colonoscopy were enrolled in the study. Patients were randomly assigned to one of three groups: video plus discussion, video alone, and discussion alone. A validated, 13-item knowledge test and the State-Trait Anxiety Inventory were administered to all patients. Mean number of correct test answers for video plus discussion was 11.04; for video alone, 10.70; and for discussion alone, 9.61. ANOVA with planned orthogonal comparisons showed that the patients in the two video groups had significantly better scores (p < 0.001) than those in the discussion-only group. No difference was noted between the two video groups (p = 0.32). Anxiety did not increase with increased understanding of the risks and benefits of colonoscopy. This approach may work as well for other invasive medical procedures and could save physician time while laying a foundation for a more personalized discussion.
