Summary

Introduction: Chronic Rhinosinusitis (CRS) is defined as inflammation of the nose and the paranasal sinuses. It is a very common disorder increasing in both incidence and prevalence with significant impact on quality of life and substantial health care costs. In this study we evaluate the prevalence of CRS in Denmark and there is a need for consensus about diagnosing this disease. Different questionnaires and different tests used for examination are evaluated together with the patients compliance and days lost through illness.

Methods: As part of Ga2len (Global Asthma and Allergy European Network) a questionnaire on CRS was posted to 5000 residents on Funen. From the completed and returned questionnaires self reported CRS was evaluated. Respondents were invited for clinical examination including spirometry, skin prick test, bloodsample and an ENT examination including nasal endoscopy, acoustic rhinometry, peak nasal inspiratory flow and smell test. Questionnaire on quality of life (EQ-5D) and symptom severity (SNOT-22) was completed. Medical diagnosed CRS was diagnosed according to the definition on CRS stated by EPOS (European Position Paper on Rhinosinusitis and Nasal Polyps 2007). CRS is defined as inflammation in the nose and paranasal sinus and should be characterized by two or more symptoms one of which should be either nasal blockage/obstruction/congestion or nasal discharge, +/- facial pain/pressure, +/- reduction or loss of smell. Endoscopic signs should be present and symptoms must have been present \> 12 weeks. Patients diagnosed with CRS were invited for a 1 year and 2 year follow up where examination and questionnaires were repeated and treatment compliance and days lost through illness were evaluated.
