The objective was to evaluate the performance of two different obstetric ultrasound simulators in assessing the practical skills of trainees compared to the standard method of practical assessment conducted on pregnant women volunteers.
We performed a prospective observational study. Two simulators were compared: the Simbionix simulator which uses a mannequin and heteroevaluation and the OPUS simulator which uses optical positioning technology with automatic assessment. All trainees who underwent the practical exam of the French national diploma in Ultrasound in Obstetrics and Gynecology in our center were recruited and assessed both on a volunteer pregnant woman and on simulator. We compared the results obtained by the trainees on the simulator with those obtained on pregnant women through correlation analysis of the scores and success rates.
Overall, 207 trainees took the practical exam and were also evaluated on the simulator: 103 on the Simbionix and 104 on the OPUS. The success rates were the following: 84.1 % (174/207) for the practical exam on pregnant woman, 81.2 % (168/207) across both simulators, 79.6 % (82/103) on Simbionix and 82.7 % (86/104) on the OPUS. There was a good correlation between the success rate of the examination using a Simbionix simulator and with pregnant women (ρ = 0.69; p < 0.001), but no correlation was observed between the OPUS simulator and pregnant women (ρ = 0.11; p = 0.23).
These data indicate that the Simbionix simulator outperforms the OPUS in assessing trainees. It could serve as a tool for screening trainees during practical assessments.
目的是评估两种不同的产科超声模拟器在评估学员实践技能方面的表现，并与对孕妇志愿者进行的标准实践评估方法进行比较。
我们进行了一项前瞻性观察研究。比较了两种模拟器：使用人体模型和他人评估的Simbionix模拟器，以及使用光学定位技术和自动评估的OPUS模拟器。招募了在我们中心参加法国国家妇产科超声文凭实践考试的所有学员，并在一名孕妇志愿者和模拟器上对他们进行评估。我们通过对分数和成功率的相关分析，比较了学员在模拟器上获得的结果与在孕妇身上获得的结果。
总体而言，207名学员参加了实践考试，并在模拟器上接受了评估：103名在Simbionix模拟器上，104名在OPUS模拟器上。成功率如下：孕妇实践考试的成功率为84.1%（174/207），两种模拟器的总体成功率为81.2%（168/207），Simbionix模拟器上的成功率为79.6%（82/103），OPUS模拟器上的成功率为82.7%（86/104）。使用Simbionix模拟器进行的考试成功率与对孕妇进行的考试成功率之间存在良好的相关性（ρ = 0.69；p < 0.001），但未观察到OPUS模拟器与孕妇之间存在相关性（ρ = 0.11；p = 0.23）。
这些数据表明，在评估学员方面，Simbionix模拟器优于OPUS模拟器。它可作为实践评估期间筛选学员的工具。
