How predictive is the Sino-Nasal Outcome Test (SNOT-22) patient-reported outcome measure regarding elective endoscopic sinus surgery (ESS) for chronic rhinosinusitis (CRS)?
Background: CRS patients must often decide to either continue with repeated medical therapy options or undergo surgery. In the absence of adequate understanding of the potential outcomes from either option, CRS patients often defer to the physician. This analysis was undertaken to determine if the SNOT-22 has the same predictive value in the U.S. and U.K. populations.
