Data on the Retrospective Bronchoscopic Intubation Cohort Study

Two external raters blinded to group and assessment number scored all 160 video recordings with a global rating scale (GRS, 8 to 40; primary outcome) and a 10-item checklist. Mixed-effects models with assessment as a categorical factor estimated between-group differences at each assessment (Holm-adjusted). Secondary outcomes were the checklist, intubation time, NASA Task Load Index (NASA-TLX), success, and safety.

Analyses were exploratory. Adding a JIT mannequin rehearsal to conventional training was associated with earlier attainment of higher blinded-rated technical quality, without detectable differences in intubation time, workload, or safety. Because the JIT group also received more practice, timing cannot be isolated; a randomized trial with a dose-matched comparator is warranted.</p>
