Development and Evaluation of the Advanced Joint Airway Management System for Educational Utility in Endotracheal...

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.

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.

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.

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.
