Basic Bronchoscopy Competence Achieved by a Nationwide One-day Simulation-based Training

In 2020, a mandatory, nationwide 1-day bronchoscopy simulation-based training (SBT) course was implemented for novice pulmonology residents in the Netherlands. This pretest-posttest study was the first to evaluate the effectiveness of such a nationwide course in improving residents' simulated basic bronchoscopy skills.

After passing a theoretical test, residents followed a 1-day SBT course, available in 7 centers, where they practiced their bronchoscopy skills step-by-step on a virtual reality simulator under pulmonologist supervision. Residents practiced scope handling efficiency (task 1) and navigational skills combined with lung anatomy knowledge (task 2). Task 1 outcome measures were navigational skill simulator metrics: percentage of time at mid-lumen, percentage of time with scope-wall contact, procedure time (PT), number of wall contacts and number of wall contacts per minute of PT. Task 2 outcome measures were PT, observational assessment scores of a validated tool with a 5-point scale (1 representing the worst and 5 the best competence) and blinded dexterity assessments.

The study included 100 residents. All outcome measures of task 1 improved significantly (P<0.001), except for the number of wall contacts per minute of PT (4.3 [IQR 3.0 to 6.2] pre vs. 3.5 [IQR 2.6 to 5.3] post, P=0.07). For task 2, PT was reduced by 54% (10.3±2.7 minutes pre vs. 4.7±0.9 minutes post, P<0.001) with an improvement in overall-competence scores (2.0 [IQR 1.0 to 2.0] pre vs. 4.0 [IQR 4.0 to 5.0] post, P<0.001) and all dexterity parameters (P<0.001).

Nationwide implementation of a SBT course led to rapid improvement of residents' basic bronchoscopy skills while halving PT.
