The SNOT-22 is a well-established validated instrument, designed to evaluate the rhinosinusitis-specific health status and health-related QOL, however makes only one broad reference to productivity. The objective of this paper is to evaluate a modified SNOT-25 created to better assess productivity with the addition of three questions:
“23) Difficulty performing regular job or household tasks; 24) Reduced time spent on job or household tasks; and 25) Limitations in type of job or household tasks performed”.
The authors were able to demonstrate construct validity, internal consistency, concurrent validity test-retest reliability and sensitivity to clinical change after assessing 120 patients with CRS at three-month intervals with the updated questionnaire. This may well prove to be a useful tool in future to allow us to demonstrate the burden of CRS and potential benefits of treatment options.
