PURPOSE During the coronavirus disease 2019 (COVID-19) pandemic, the number of abdominal hysterectomy procedures decreased in Indonesia. The existing commercial abdominal hysterectomy simulation model is expensive and difficult to reuse. This study compared residents' abdominal hysterectomy skills after simulation-based training using the Surabaya hysterectomy mannequin following a video demonstration. METHODS We randomized 3rd- and 4th-year obstetrics and gynecology residents to a video-based group (group 1), a simulation-based group (group 2), and a combination group (group 3). Abdominal hysterectomy skills were compared between before and after the educational intervention. The pre- and post-tests were scored by blinded experts using the validated Objective Structured Assessment of Technical Skills (OSATS) and Global Rating Scale (GRS). RESULTS A total of 33 residents were included in the pre- and post-tests. The OSATS and GRS mean differences after the intervention were higher in group 3 than in groups 1 and 2 (OSATS: 4.64 [95% CI, 2.90-6.37] vs. 2.55 [95% CI, 2.19-2.90] vs. 3.82 [95% CI, 2.41-5.22], P=0.047; GRS: 10.00 [95% CI, 7.01-12.99] vs. 5.18 [95% CI, 3.99-6.38] vs. 7.18 [95% CI, 6.11-8.26], P=0.006). The 3rd-year residents in group 3 had greater mean differences in OSATS and GRS scores than the 4th-year residents (OSATS: 5.67 [95% CI, 2.88-8.46]; GRS: 12.83 [95% CI, 8.61-17.05] vs. OSATS: 3.40 [95% CI, 0.83-5.97]; GRS: 5.67 [95% CI, 2.80-8.54]). CONCLUSION Simulation-based training using the Surabaya hysterectomy mannequin following video demonstration can be a bridge to learning about abdominal hysterectomy for residents who had less surgical experience during the COVID-19 pandemic.

在印度尼西亚 COVID-19 大流行期间，使用新型泗水子宫切除术模型进行基于模拟的培训，以提高产科和妇科住院医师的腹部子宫切除术技能：干预前和干预后研究。

目的 在 2019 年冠状病毒病 (COVID-19) 大流行期间，印度尼西亚腹部子宫切除术的数量有所减少。现有的商业腹部子宫切除术模拟模型价格昂贵且难以重复使用。本研究在视频演示后使用泗水子宫切除术人体模型进行了基于模拟的培训，比较了住院医师的腹部子宫切除术技能。方法 我们将第 3 年和第 4 年的妇产科住院医师随机分为基于视频的组（第 1 组）、基于模拟的组（第 2 组）和组合组（第 3 组）。比较了教育干预前后的腹部子宫切除术技能。前测和后测由盲法专家使用经过验证的技术技能客观结构化评估 (OSATS) 和全球评分量表 (GRS) 进行评分。结果共有33名居民参加了前测和后测。干预后第 3 组的 OSATS 和 GRS 平均差异高于第 1 组和第 2 组（OSATS：4.64 [95% CI, 2.90-6.37] vs. 2.55 [95% CI, 2.19-2.90] vs. 3.82 [95 % CI, 2.41-5.22], P=0.047; GRS: 10.00 [95% CI, 7.01-12.99] vs. 5.18 [95% CI, 3.99-6.38] vs. 7.18 [95% CI, 6.11-8.26], P =0.006)。第 3 组中的第 3 年居民在 OSATS 和 GRS 评分上的平均差异大于第 4 年居民（OSATS：5.67 [95% CI，2.88-8.46]；GRS：12.83 [95% CI，8.61-17.05] vs . OSATS：3.40 [95% CI，0.83-5.97]；GRS：5.67 [95% CI，2.80-8.54]）。
