Low-Cost Model Versus Airway Part-Task Trainer for Flexible Bronchoscope-Guided Tracheal Intubation Training

This study evaluates the effectiveness of a low-cost, locally designed simulation model (RAN) for flexible bronchoscope-guided tracheal intubation (FBTI) training, compared to a commercial airway part-task trainer. It aims to assess residents' skill acquisition, retention, and proficiency, promoting affordable simulation-based training. The study follows a three-phase design: Delphi Phase: Experts develop a standardized Global Rating Scale (GRS) for assessing FBTI skills through consensus. Intermediate Phase: Piloting the tool with advanced trainees to ensure reliability and validity. Main RCT Phase: PGY 1 and 2 residents, with no prior FBTI experience, are recruited from eight medical centers in Lebanon. Participants are randomly assigned to either the experimental (RAN model) or control (commercial trainer) group. Their FBTI skills are evaluated after training, and again at 3- and 6-month follow-ups, using the GRS on a high-fidelity airway simulator. Data collection focuses on skill performance, with statistical models analyzing changes over time and between groups. The study aims to improve training accessibility while maintaining educational effectiveness.

Phase 1: Expert committee Intermediate phase: Postgraduate fellows and residents from pulmonology and ENT, along with senior anesthesia residents Phase 2: Inclusion criteria include PGY 1 and 2 levels with no previous experience with FBTI and belonging to one of the eight prespecified medical centers. Any resident with prior exposure and experience with FBTI will be excluded.
