Understanding pelvic anatomy is an important part of education during obstetrics and gynecology residency. Traditional teaching methods to learn pelvic anatomy have obstacles and are often costly.
We provide a self-constructed clay pelvic model to aid in the mastery of pelvic anatomy for obstetrics and gynecology residents and to estimate whether building a clay pelvic model would increase residents' confidence and knowledge in pelvic anatomy.
Each resident constructed a clay pelvic model on a bony pelvis, along with the traditional didactic on pelvic anatomy. Demographics of the participants were obtained, followed by a knowledge test and confidence level and satisfaction surveys. Descriptive analysis and Wilcoxon signed-rank test were used for data analysis. Nine residents (three postgraduate year [PGY]-1, one PGY-2, two PGY-3, three PGY-4) completed the knowledge and confidence questions before and after the simulation, along with the satisfaction survey. The median score from the 10 multiple-choice knowledge questions was 50% (30-70%) on the pretest and 70% (40-100%) on the posttest (P=not significant). Although most residents scored higher on the posttest, two residents scored 10% lower. Overall, 66.7% of residents improved their knowledge scores up to 30% after the simulation session. Self-assessed confidence level scores improved from 2-3 to 4 (1, lowest; 5, highest) for all questions asked (P=.010 to approximately .019). A majority of residents responded with 4 or 5 to the satisfaction statements.
A low-budget clay pelvic model is easy to build and did increase residents' confidence in pelvic anatomy knowledge and satisfaction. Self-constructing a clay pelvic model would provide an excellent way of reviewing the major landmarks of pelvic anatomy.
了解骨盆解剖学是妇产科住院医师培训的重要组成部分。学习骨盆解剖学的传统教学方法存在障碍，且往往成本高昂。
我们提供了一个自行构建的粘土骨盆模型，以帮助妇产科住院医师掌握骨盆解剖学，并评估构建粘土骨盆模型是否会增加住院医师对骨盆解剖学的信心和知识。
每位住院医师都在骨盆骨上构建了一个粘土骨盆模型，并结合传统的骨盆解剖学教学。我们获得了参与者的人口统计学数据，随后进行了知识测试以及信心水平和满意度调查。采用描述性分析和 Wilcoxon 符号秩检验进行数据分析。九名住院医师（3 名 PGY-1、1 名 PGY-2、2 名 PGY-3、3 名 PGY-4）在模拟前后完成了知识和信心问题以及满意度调查。10 个多项选择题的知识问题的中位数分数在预测试中为 50%（30-70%），在后测试中为 70%（40-100%）（P=无显著差异）。尽管大多数住院医师在后测中的得分较高，但有两名住院医师的得分低了 10%。总体而言，66.7%的住院医师在模拟课程后知识得分提高了 30%。所有问题的自我评估信心水平得分从 2-3 提高到 4（1 分最低，5 分最高）（P=.010 到大约.019）。大多数住院医师对满意度陈述的回答为 4 或 5。
一个低成本的粘土骨盆模型易于构建，确实增加了住院医师对骨盆解剖学知识的信心和满意度。自行构建粘土骨盆模型将提供一种极好的复习骨盆解剖学主要标志的方法。
