We evaluated the validity and efficacy of a pediatric airway foreign body simulation for otolaryngology resident training.
We created a course using a high-fidelity toddler mannequin designed to instruct and evaluate otolaryngology residents in pediatric airway foreign body management. Seven junior and 5 senior residents participated. Their performance was evaluated by 2 observers using an Objective Structured Assessment of Technical Skills (OSATS) instrument.
By the third trial, all junior and senior residents scored a proficiency level of "independent without errors" or "independent and efficient," and the performance of the junior residents was not different from that of the senior residents. After completing the course, the junior residents self-rated their abilities as commensurate with those of a senior resident, and senior residents rated themselves capable of performing foreign body extraction without supervision. All participants felt that the course and simulator had good overall realism and a realistic feel, demonstrating face validity. Perhaps most importantly, the residents' highest ratings were for "facilitated management of complications" and "facilitated working with the operating room team"--areas difficult to teach during live surgical procedures.
This pediatric airway foreign body course using a high-fidelity simulator has face and construct validity, and results in statistically improved performance and self-evaluation of all participants.
我们评估了用于耳鼻咽喉科住院医师培训的小儿气道异物模拟的有效性和效能。
我们使用一个高保真幼儿人体模型创建了一门课程，旨在指导和评估耳鼻咽喉科住院医师对小儿气道异物的处理。7名初级住院医师和5名高级住院医师参与其中。由2名观察员使用客观结构化技能评估（OSATS）工具对他们的表现进行评估。
到第三次试验时，所有初级和高级住院医师的熟练程度均达到“独立无差错”或“独立且高效”水平，初级住院医师的表现与高级住院医师无异。完成课程后，初级住院医师自我评估其能力与高级住院医师相当，高级住院医师则认为自己能够在无监督的情况下进行异物取出操作。所有参与者都认为该课程和模拟器具有良好的整体逼真度和真实感，显示出表面效度。也许最重要的是，住院医师对“便于并发症处理”和“便于与手术室团队合作”的评价最高，而这些是在实际手术过程中难以教授的领域。
这门使用高保真模拟器的小儿气道异物课程具有表面效度和结构效度，并在统计学上提高了所有参与者的表现和自我评估。
