Data_Sheet_10_Development and evaluation of a “simulator-based” ultrasound training program for university teaching in obstetrics and gynecology–the prospective GynSim study.PDF

IntroductionThis study addresses the challenges of ultrasound education in obstetrics and gynecology, focusing on the potential benefits of simulation techniques in medical training. Aiming to evaluate the impact of a structured simulator-based training program, this prospective, randomized, interventional study examines its effects on educational outcomes for 5th year medical students.
MethodsA total of 153 medical students were randomized into two groups: one receiving both theoretical instruction and hands-on ultrasound simulator training (study group), and the other receiving only theoretical instruction (control group). The study assessed theoretical knowledge and practical skills at two time points: upon enrollment and at the end of the course. The practical skills were specifically evaluated using a dedicated test on the ultrasound simulator.
ResultsOut of 153 students, 113 completed the study (study group n=59, control group n=54). The students in the study group demonstrated a greater improvement in theoretical test scores. They also achieved better results at the practical test, with regard to image quality, accuracy, and efficiency. Both groups showed an increase in self-confidence and competency in performing ultrasound examinations independently. Students expressed high satisfaction with the course and a positive attitude toward simulator-based training.
DiscussionSimulator-based training presents a valuable supplement to traditional clinical education methods in obstetrics and gynecology. This approach is particularly effective in overcoming the challenges posed by the sensitive nature of gynecological examinations in medical student training. The study highlights the benefits of integrating simulator-based methods into medical curricula, improving both theoretical and practical ultrasound skills among students.

引言：本研究针对妇产科学超声教学所面临的挑战，聚焦模拟技术在医学培训中的潜在应用价值。本前瞻性随机对照干预研究旨在评估结构化模拟器培训项目的教学效果，考察其对五年级医学生教学成果的影响。
方法：共计153名医学生被随机分为两组：试验组（study group）同时接受理论授课与实操超声模拟器（ultrasound simulator）培训，对照组（control group）仅接受理论授课。研究分别在入组时与课程结束时两个时间点，对受试者的理论知识与实操技能进行评估。其中实操技能评估采用专用超声模拟器测试完成。
结果：153名学生中共有113名完成本研究（试验组n=59，对照组n=54）。试验组学生的理论测试成绩提升更为显著；在实操测试中，其在图像质量、操作准确性与效率方面均取得更优表现。两组学生独立完成超声检查的自信心与专业胜任力均有所提升。参与学生对本课程满意度较高，且对模拟器培训持积极认可态度。
讨论：模拟器培训可作为妇产科学传统临床教学方法的有益补充，尤其能有效解决妇科检查敏感性给医学生培训带来的实操难题。本研究凸显了将模拟器培训整合入医学课程的显著优势，可同时提升学生的超声理论知识与实操技能。
