The Video Classification of Intubation (VCI) score for videolaryngoscopy: a multicentre international feasibility study
Authors' conclusion
The VCI score exhibits high inter-rater reliability across a wide range of clinical settings and patient populations, among airway-competent clinical staff of diverse experience and backgrounds.
