The chronic rhinosinusitis with nasal polyp patient journey in the United States and Europe

In this letter to the editor, we present questionnaire-based data assessing the patient journey of adults with moderate–severe Chronic Rhinosinusitis with Nasal Polyps (CRSwNP) in the USA and five European countries. These data highlight how long and difficult the patient journey with CRSwNP can be and how improved disease awareness among physicians could lead to more timely diagnosis and treatment, and hence improved management of patients.
