Abstract

Objective: To compare the efficacy of a three-dimensional (3D) haptic interface to a two-dimensional (2D) mouse interface for a screen-based simulation (SBS) neonatal intubation (NI) training intervention. Primary hypothesis: a haptic interface is more effective than a mouse interface for SBS training intervention for NI. Secondary hypothesis: SBS training, regardless of interface, will result in improved NI performance on a neonatal airway simulator.

Methods: 45 participants were randomised to either a haptics or a mouse interface to complete an identical SBS training intervention for NI over a five-month period. Participants completed pre- and post-training surveys to assess demographics, experience, knowledge and attitudes. The primary outcome of participants' NI skills performance was assessed on a neonatal manikin simulator. Skills were measured pre- and post- training by number of attempts and time to successfully intubate, and airway visualization.

Results: The demographics, training and experience were similar between groups. There was no difference in the improvement in skills, knowledge, attitudes or satisfaction ratings pre- and post-training between the groups. There was a significant decrease in number of attempts to intubate a neonatal airway simulator (2.89 vs 1.96, p<0.05) and improvement in the percent of subjects intubating in <30 seconds (22% vs 27%, p=0.02) from pre- to post-training in the study population overall.

Conclusion: Using a haptic interface did not have an advantage over a mouse interface in improving NI skills, knowledge, attitudes, or satisfaction. Overall, a SBS training intervention for NI improved skills measured on a neonatal airway simulator.
