Educational Effects of Simulation and Non-Simulation Training in Airway Management according to Levels of the Kirkpatrick Model: A Systematic Review and Network Meta-Analysis

There is insufficient validation of the effectiveness of simulation-based training (Sim) or non-simulation-based training (non-Sim) for teaching airway management to healthcare professionals within the literature. We thus conducted a network meta-analysis comparing the effectiveness of Sim, non-Sim, and no educational intervention (NI) for airway management. The primary endpoints were knowledge scores (KnS) and behavioral performance scores (BpS) corresponding to assessments at levels 2 and 3 of the Kirkpatrick model, respectively. Effect sizes were expressed as standardized mean differences (Std. MD) and 95% credible intervals (CrIs). Regarding KnS, the educational effects of Sim and non-Sim were significantly improved compared to those of NI (Std. MD [95% CI]: 1.110 [0.903–1.316] and 0.819 [0.209–1.429], respectively); there was no significant difference between Sim and non-Sim. The educational effect of Sim in BpS was significantly improved compared to that of non-Sim and NI (0.850 [0.015–1.691] and 0.660 [0.241–1.076]); there were no differences between non-Sim and NI. Surface under the cumulative rank curve values demonstrated that Sim ranked highest in efficacy for KnS and BpS. This study provides valuable information regarding the educational efficacy of Sim and non-Sim in airway management. Larger randomized controlled trials are needed to confirm these findings.
