q3 i? Although high-fidelity VR simulators such as ORSIM show the strongest predictive-validity evidence, their educational superiority over simpler low-fidelity models has not been demonstrated. → McCarthy Roisin 2026

McCarthy Roisin, Maher Liam, O'Dea Angela. (2026). Validation status of definitive airway management simulators: a systematic review. BJA: British Journal of Anaesthesia. https://doi.org/10.1016/j.bja.2026.01.027

q3 · i? · review · r3

Narrative synthesis in the review's discussion of fibreoptic intubation simulators, comparing high-fidelity VR models with low-fidelity bench models such as the 'choose-the-hole' model, which also demonstrated predictive validity in an RCT.

"Overall, although high-fidelity VR simulators such as ORSIM® demonstrate the strongest evidence for predictive validity, their educational superiority over simpler models has not yet been demonstrated."
