Description
Summary:Introduction: stridor is the most common presenting symptom of pediatric airway obstruction, yet its value in clinical diagnosis is undetermined. The purpose of this study was to determine what diagnostic information was available to clinicians based entirely on listening to infantile stridor. Method: ten taped samples of stridor and corresponding clinical summaries were independently scored by Pediatric Otolaryngologists and their trainees. Respondents were asked to score the ‘perceived’ severity of the stridor based on their aural perception. Participants were recruited by an advertisement on the Internet Pediatric Otolaryngology forum. Thirty-eight consultants and 22 trainees responded. The responses were compared to known outcomes in the ten patients presented. Results: listening to stridor in isolation resulted in respondents performing at the level of chance when their score of ‘perceived’ severity was compared to the known clinical outcome. When the clinical summaries (of the same patients) were scored, the level of performance significantly improved ( P
