Interrater and Intrarater Reliability of Philpott-Javer and Kupferberg Staging following Sinus Surgery Based on Training

Objectives:The Philpott-Javer and Kupferberg endoscopic mucosal staging systems for allergic fungal rhinosinusitis have previously demonstrated acceptable inter-rater reliability among rhinologists. There are, however, numerous learners involved in patient care at tertiary centers. This study aims to 1) Analyze the inter-rater and intra-rater reliability of the Philpott-Javer and Kupferberg scoring systems among otorhinolaryngology learners at different stages in training; 2) Analyze whether the Philpott-Javer scoring system can be used reliably by learners compared to an experienced rhinologist.Methods:This retrospective study examined the endoscopic photographs of patients who had undergone post-surgical endoscopy at a tertiary sinus center in January 2013. 150 Images (3 images randomly selected from 50 patients) were played twice, one week apart, in a randomized loop and scored according to Philpott-Javer and Kupferberg criteria by a staff rhinologist, a rhinology fellow, a senior otorhinolaryngology r...
