Abstract

Background: Ideal management of chronic rhinosinusitis (CRS) requires ongoing monitoring of disease and its control. Existing control instruments are limited in their correlation to patient reported outcomes, the need for endoscopy, or lack of validation from a multidisciplinary group. The goal of this study was to develop a patient-based Sinus Control Test (SCT) for determining CRS control. Methods: A systematic literature review and focus groups consisting of 20 patients and 11 medical experts in CRS from various medical specialties were used to generate items. A draft 13-item questionnaire was administered to 50 patients with CRS in a prospective fashion. Patients were evaluated using the 22-item Sino-Nasal Outcome Test (SNOT-22) instrument, Lund-Mackay computed tomography (CT) score, and Lund-Kennedy endoscopy score. A rhinologist blinded to the questionnaire results also provided an overall control of the disease for each patient. A regression model was generated to identify which subset of items showed the greatest discriminate ability in relation to specialist's and patient's global rating of disease control. Results: Four questions were included in the final questionnaire (p <0.05), each with a scale of 0 to 4, with an overall total score ranging from 0 to 16. Optimal classification resulted in patients with a score from 1 to 3 (well controlled), 4 to 11 (partially controlled), and 12 to 16 (uncontrolled). SCT scores correctly classified control levels 72% of the time when compared to physician's assessment. Conclusion: The SCT is a simple, patient generated questionnaire that can measure the control of CRS without requirement of endoscopy or CT evaluation.
