Discordance of chronic rhinosinusitis disease control between EPOS guidelines and patient perspectives identifies utility of patient-rated control assessment

The objective of this study was to determine concordance of patient-reported chronic rhinosinusitis (CRS) disease control with CRS disease control assessed according to European Position Paper on Rhinosinusitis and Nasal Polyps (EPOS) criteria.In 421 participants, CRS disease control was determined using EPOS criteria which include the burden of 5 symptoms measured on a binary scale, use of rescue medications in the prior 6 months and presence of diseased mucosa on nasal endoscopy. Symptom severity was also assessed using a visual analogue scale (VAS). Participants rated their CRS disease control as "controlled","partly controlled" or "uncontrolled".Patient-reported and EPOS-based CRS disease control ratings agreed for 49.6% of participants. Amongst cases of disagreement, EPOS guidelines assessed worse CRS disease control relative to 92.9% of patients. Facial pain/pressure and impaired sense of smell distinctly associated with patient agreement with EPOS guidelines on having "uncontrolled" CRS. Higher VAS symptom scores were associated with worse patient-reported CRS disease control (i.e., agreeing with EPOS guidelines). Removal of the nasal endoscopy criterion improved agreement between patients' and EPOS control assessments, and replacement of this criterion with patient-reported control further aligned EPOS guidelines with patient perspectives.EPOS guidelines regularly assess worse CRS control than assessed by patients. The lack of more gradated symptom severity criteria and inclusion of nasal endoscopy may contribute to discordance of EPOS guidelines with patient-reported CRS control. Replacement of nasal endoscopy findings with a measure of patient-reported CRS disease control better aligns EPOS CRS disease control guidelines with patients' perspectives.
