Abstract
BackgroundThe implementation of simulation-based training (SBT) to teach flexible bronchoscopy (FB) skills to novice trainees has increased during the last decade. However, it is unknown whether SBT is effective to teach FB to novices and which instructional features contribute to training effectiveness.Research QuestionHow effective is FB SBT and which instructional features contribute to training effectiveness?Study Design and MethodsWe searched Embase, PubMed, Scopus, and Web of Science for articles on FB SBT for novice trainees until November 10, 2022. We assessed methodologic quality of included studies using a modified version of the Medical Education Research Study Quality Instrument, evaluated risk of bias with relevant tools depending on study design, assessed instructional features, and intended to correlate instructional features to outcome measures.ResultsWe identified 14 studies from an initial pool of 544 studies. Eleven studies reported positive effects of FB SBT on most of their outcome measures. However, risk of bias was moderate or high in eight studies, and only six studies were of high quality (modified Medical Education Research Study Quality Instrument score ≥ 12.5). Moreover, instructional features and outcome measures varied highly across studies, and only four studies evaluated intervention effects on behavioral outcome measures in the patient setting. Simulation training programs in studies with the highest methodologic quality and most relevant outcome measures all included curriculum integration and range in task difficulty.InterpretationAlthough most studies reported positive effects of simulation training programs on their outcome measures, definitive conclusions regarding training effectiveness on actual bronchoscopy performance in patients could not be made because of heterogeneity of training features and the sparse evidence of training effectiveness on validated behavioral outcome measures in a patient setting.Trial RegistrationPROSPERO; No.: CRD42021262853; URL: https://www.crd.york.ac.uk/prospero/ The implementation of simulation-based training (SBT) to teach flexible bronchoscopy (FB) skills to novice trainees has increased during the last decade.

However, the effects of simulation training on skill performance of novices in a patient setting are less clear because of a lack of studies using homogeneous validated outcome measures. Integrating bronchoscopy simulation training programs in the curriculum and increasing task difficulty appear to contribute to training effectiveness.Interpretation: To further improve our knowledge of the effectiveness of bronchoscopy simulation-based training and how to optimize these training programs, we advocate that future studies use more homogeneous validated outcome measures, preferably in a patient setting.

Use of simulation in health professions education has increased significantly over the past two decades.1Ryall T. Judd B.K. Gordon C.J.
