BACKGROUND: To evaluate the efficacy of a simulation-based mastery curriculum to train clinicians with limited-to-no sonography experience how to use ultrasound (US) to assess neonatal endotracheal tube (ETT) positioning.
METHODS: In a single-centered, prospective, educational study, 29 neonatology clinicians participated in a simulation-based mastery curriculum composed of a didactic lecture, followed by a one-on-one simulation session using a newly designed, three-dimensional (3D) printed US phantom model of the neonatal trachea and aorta. After mastery training, clinicians were evaluated with a performance checklist on their skills obtaining US images and assessing ETT positioning in the US phantom model. They also completed pre- and postcurriculum knowledge assessment tests and self-assessment surveys. The data were analyzed using Wilcoxon signed rank tests and repeated measures analysis of variance.
RESULTS: The mean checklist score improved significantly during three attempts (mean difference: 2.6552; 95% confidence interval [CI]: 2.2578-3.0525; P < 0.0001). The mean time to perform US decreased significantly from the first to third attempt (mean difference: -1.8276 min; 95% CI: -3.3391 to - 0.3161; P = 0.0196). In addition, there was a significant improvement in median knowledge assessment scores (50% vs. 80%; P < 0.0001) and survey ratings on knowledge and self-efficacy (P < 0.0001).
CONCLUSION: Clinicians with limited-to-no sonography experience demonstrated improved knowledge and skill acquisition in using US to assess ETT positioning through simulation-based mastery training. The use of 3D modeling enhances simulation experiences and optimizes the quality of training during limited opportunities to achieve procedural competency in a controlled environment before further application into the clinical setting.
