Mental practice exercises are based on repeated visualization of motor actions without physically performing them, thereby promoting the learning of skills. We aimed to evaluate whether a teaching intervention including mental practice exercise modules for the acquisition of bronchoscopy skills improves fiberoptic intubation performance of novice learners.METHODS: In this prospective cohort study, 24 pediatric intensive care trainees and respiratory therapists participating in a bronchoscopy learning curriculum in 2016–2017 attended a theoretical lecture followed by self-guided learning. Subsequently, the learners were randomly assigned to either participating in a teaching intervention including mental practice exercises or not (control group). The primary outcome was time to complete their first bronchoscopic intubation using a virtual reality simulator. Secondary outcomes were the occurrence of “red outs” (ie, the anatomy could no longer be visualized) or collisions with the airway wall. Bayesian Poisson Mixture models were used to estimate the effect of the intervention on outcomes. Furthermore, participation in the teaching intervention was examined in short interviews and with descriptive thematic analysis.RESULTS: Subjects in the intervention group completed the bronchoscopy on average 1.2 times faster (rate ratio 1.2 [95% credible intervals 1.1–1.3]). The posterior probability that the teaching intervention reduced the occurrence of “red outs” by more than half was 86%. No differences were found regarding the odds of colliding with the airway wall. Everyone except 1 trainee in the mental practice group engaged with and found the mental practice modules helpful.CONCLUSIONS: A teaching intervention including mental practice exercises represents a valuable additional learning strategy promoting the performance and complex skill acquisition of novice learners in the initial stages of learning bronchoscopy procedures.
