BackgroundDiagnostic criteria for emergence agitation are sensitive but not specific; they misclassify patients who are angry or upset as having emergence delirium.AimsThe aim of this three-phase study was to determine expert agreement on the behaviors that differentiate children with emergence delirium from those without.MethodsIn the first phase of this observational study, pediatric dental patients were video recorded while awakening from anesthesia. In the second phase, salient 10 s segments of the recordings showing patient activity were shown to an expert audience of pediatric dentists, anesthesiologists and Post Anesthetic Care nurses, who scored the recordings as showing or not showing "true emergence delirium." In phase 3, the video segments were assessed by three research assistants using a behavior checklist for features that discriminate between those scored "true emergence delirium" and those scored "NOT true emergence delirium" by the experts.ResultsOne hundred and fifty-four pediatric dental patients were included. Subsequently, an expert audience consisting of 10 anesthesiologists, 12 anesthesiology residents, 3 pediatric dentists, and 4 experienced Post Anesthesia Care Unit nurses rated each 10-second video segment. This resulted in three groups of patients: a group for whom all experts agreed was "True emergence delirium" (n = 33; CI 21 to 45), a group for whom all agreed was "Not True emergence delirium" (n = 120; CI 107 to 133), and a group where experts disagreed (n = 11; CI 4 to 18). Three research assistants then completed a behavior checklist for each of the 33 "True emergence delirium" video segments and matched "Not True" controls. Twenty-four behaviors were identified as significantly different between videos scored True emergence delirium and those scored Not True emergence delirium. Research assistants reached almost perfect agreement (0.81-1.00) on one behavior, and substantial agreement (0.61-0.80) on seven behaviors that characterized "True emergence delirium."ConclusionsEight behaviors that differentiate pediatric dental patients with emergence delirium from those without were found. These discriminators may be used to develop a scale that will lead to better diagnosis and treatment of emergence delirium.© 2023 John Wiley & Sons Ltd.
