Validation of the POGO Score for Classification of Videolaryngoscopy in Children - Post-hoc Analysis of the PeDiAC Study

External Validation of the POGO Score for Classification of Videolaryngoscopic Intubation in Children and Comparison With the Quality of the Glottic View Rated on Visual Analogue Scales - Post-hoc Analysis of the Prospective PeDiAC Study

It has been assumed that the percentage of glottic opening (POGO) score might enhance the classification of videolaryngoscopic tracheal intubation by offering a more objective rating of glottic exposure but studies in children are lacking. This post hoc analysis of the prospective observational PeDiAC study aims to investigate, if classifying difficult videolaryngoscopic tracheal intubation with the POGO score is superior to a subjective rating of the quality of the glottic view on visual analogue scales (VAS). Post hoc video analysis will be performed by multiple independent raters. A secondary aim is to determine the diagnostic performance of the POGO and VAS for the prediction of relevant user- and patient-centered outcomes and to assess the inter-rater reliability of the POGO score.
