What the result means
- Scale
- 22 items, each 0 to 5, over the past two weeks. Total 0 to 110. Higher is worse.
- Below 8
- No named band. The source defines nothing under 8 and calls it no clinically significant symptoms. NOT mild.
- 8 to 20
- Mild.
- Above 20 to 50
- Moderate.
- Above 50
- Severe.
- Provenance
- The questionnaire itself defines NO bands. These come from a separate 2016 study of 65 patients.
- MCID
- 8.9 applies to the DIFFERENCE between two scores from one patient, not to a single total.
- Not scored
- The form's "most important items" selection is a descriptor. Never summed or weighted.
- Scope
- Patient-reported symptom burden. Does not diagnose rhinosinusitis; not an indication for surgery.
