Patient's retention and recall of material discussed in a medical consultation is often inadequate.
To assess patient's knowledge, anxiety, and understanding of Mohs surgery after viewing a brief educational video.
A prospective, investigator-blinded, randomized controlled trial of 120 consecutive patients before the first Mohs surgery procedure. Sixty subjects viewed an instructional video and 60 subjects did not. A survey was administered to both groups, measuring knowledge, anxiety, and understanding of Mohs surgery.
The video group scored higher than the control group on the knowledge portion of the survey (median score 78% vs 56%, p < .01), but there were no differences in anxiety or understanding scores between groups. The percentage of subjects who answered each knowledge question correctly was greater in the video group than in the control group. In the subgroup of patients who had not previously had a consultation with a Mohs surgeon, the video group had higher median knowledge scores (67% vs 44%, p < .01), higher median understanding scores (8 vs 6, p = .05), and lower median visual analogue anxiety scores (4 vs 6, p = .01) compared with the control group.
A brief educational video increases patient's knowledge of Mohs surgery. For patients who have not yet had a consultation with a Mohs surgeon, the video may also reduce anxiety.
患者在医疗咨询中对所讨论内容的保留和回忆往往不足。
评估患者在观看简短的教育视频后对 Mohs 手术的知识、焦虑和理解程度。
这是一项针对 120 例首次 Mohs 手术前连续患者的前瞻性、研究者盲法、随机对照试验。60 例患者观看教学视频，60 例患者不观看。对两组患者进行问卷调查，测量对 Mohs 手术的知识、焦虑和理解程度。
观看视频组在调查的知识部分的得分高于对照组（中位数为 78%比 56%，p <.01），但两组在焦虑或理解评分方面没有差异。在视频组中，回答每个知识问题的患者比例高于对照组。在从未与 Mohs 外科医生进行过咨询的亚组患者中，观看视频组的知识评分中位数较高（67%比 44%，p <.01），理解评分中位数较高（8 比 6，p =.05），视觉模拟焦虑评分中位数较低（4 比 6，p =.01）与对照组相比。
简短的教育视频增加了患者对 Mohs 手术的知识。对于尚未与 Mohs 外科医生进行咨询的患者，视频还可能减轻焦虑。
