To assess the effectiveness of an instructional DVD on the anatomy and repair of anal sphincter lacerations to improve postgraduate trainees' understanding.
A total of 71 obstetrics and gynecology trainees completed a pretest of third- and fourth-degree lacerations to assess baseline knowledge and perceptions. Question categories included anatomy, antibiotics, anesthesia, repair methods, complications, postoperative care, and risk factors. After 1 year of clinical experience, 67 trainees (94%) were randomly assigned into DVD (intervention) and non-DVD (control) groups. A post-test was administered 4 weeks later.
In the DVD group (n=34), mean scores on the pretest versus the post-test were 65% vs 74% for postgraduate year (PGY)-1 (P=0.09); 72% vs 83% for PGY-2 (P=0.06); 67% vs 83% for PGY-3 (P=0.01); and 75% vs 87% for PGY-4 (P<0.001). In the non-DVD group (n=33), mean scores did not change significantly for any year level. The increase in score from pretest to post-test was significantly different between the 2 groups, independent of year (P<0.001). DVD group scores improved significantly over non-DVD group scores in anatomy (P=0.005) and repair methods (P=0.042) subscales.
An educational video is an effective tool for improving understanding of third- and fourth-degree lacerations for physicians-in-training.
评估解剖和修复肛门括约肌裂伤教学 DVD 对提高研究生理解能力的有效性。
共有 71 名妇产科学员完成了第三和第四度裂伤的前测，以评估基线知识和认知。问题类别包括解剖、抗生素、麻醉、修复方法、并发症、术后护理和危险因素。在 1 年的临床经验后，67 名学员（94%）被随机分为 DVD（干预）和非 DVD（对照）组。4 周后进行后测。
在 DVD 组（n=34），研究生第 1 年（PGY-1）的前测与后测平均分数分别为 65%对 74%（P=0.09）；PGY-2 为 72%对 83%（P=0.06）；PGY-3 为 67%对 83%（P=0.01）；PGY-4 为 75%对 87%（P<0.001）。在非 DVD 组（n=33），各年级的平均分数均无显著变化。两组之间从前测到后测的分数增加差异显著，与年级无关（P<0.001）。DVD 组在解剖（P=0.005）和修复方法（P=0.042）分量表上的分数提高明显优于非 DVD 组。
教育视频是提高受训医师对第三和第四度裂伤理解的有效工具。
