Development and Evaluation of the Advanced Joint Airway Management System for Educational Utility in Endotracheal Intubation, as Assessed by Expert Paramedic Instructors.

ABSTRACT

INTRODUCTION: Between 2011 and 2014, The Combat Casualty Training Consortium research study sought to evaluate all aspects of combat casualty care, including mortality, with a special focus on the incidence and causes of potentially preventable deaths among U.S. combat fatalities. This study identified a major training gap in critical airway management. To address this gap, the Advanced Joint Airway Management System (AJAMS) was designed and assessed for physical fidelity and educational utility in a population of paramedic instructors. MATERIALS AND METHODS: Paramedic instructors served as participants in this prospective observational pilot study (n = 12). Participants interacted with three airway management trainers The AJAMS trainer, the Laerdal Airway Management Trainer, and the TruCorp AirSim Advance Bronchi X Trainer. Participants then completed an evaluation of the trainer using a purpose-built data collection instrument that queried the trainer's realism and educational utility. Within-group differences were analyzed via a 1-way repeated measures ANOVA, with a Bonferroni post hoc analysis. Rank data were analyzed via non-parametric Freidman's test, and Wilcoxon signed-rank test post hoc analysis, corrected using the Bonferroni correction. RESULTS: The AJAMS trainer conveys significantly more physical fidelity (visual P < .001, ηp2 = 0.977; tactile P < .001, ηp2 = 0.983; and behavioral P = .001, ηp2 = 0.971) and overall educational utility (χ2(2) = 15.273, P < .001) than the two commercially available skill trainers. CONCLUSIONS: These data suggest that physical fidelity is an important attribute in the design of simulators for health care, as perceived by expert instructors. These data illustrate that the AJAMS-integrated simulator demonstrates unparalleled physical fidelity, relative to commercially available airway management skill trainers.
