The Sino-Nasal Outcome Test-22 as a tool to identify chronic rhinosinusitis in adults with cystic fibrosis.

Background: Chronic rhinosinusitis (CRS) is becoming increasingly prevalent in adults with cystic fibrosis (CF), as the median age of survival rises for these individuals. Delayed identification of CRS may contribute to worsening health-related quality of life and increased treatment burden. Our objective was to investigate the utility of the 22-item Sino-Nasal Outcome Test (SNOT-22) as a tool to identify CRS in adults with CF.
