Rhinosinusitis Task Force Symptoms versus the Sinonasal Outcomes Test in Patients Evaluated for Chronic Rhinosinusitis

Abstract

The aim of this study was to compare Rhinosinusitis Task Force (RSTF) symptom scores with Sinonasal Outcome Test 20 (SNOT-20) in patients with chronic rhinosinusitis (CRS) and controls. An analysis was performed of prospectively collected data in patients with CRS (n=201) and controls (n=100). The severity of individual RSTF major and minor symptom scores graded on a visual analog scale and total symptom scores were compared between the two groups. Correlation of the RSTF symptoms with the SNOT-20 was performed using data collected from the CRS group at baseline and at 1 year postoperatively. CRS patients had higher RSTF symptom scores compared with control patients when asked to rate the severity of nasal obstruction, facial pain/pressure, facial congestion, alteration of smell, nasal discharge, postnasal drip, headache, halitosis, fatigue, cough, and ear pain (p < 0.005). No statistically significant difference was seen for the symptoms of dental pain and fever. Total RSTF scores were 54.5 +/- 1.9 in CRS patients versus 23.4 +/- 3.0 in controls. Total SNOT-20 scores were 28.7 +/- 0.8 in CRS patients versus 15.2 +/- 0.6 in controls. In CRS patients, total RSTF scores correlated with total SNOT-20 scores at baseline (r = 0.36; p < 0.0001) and 1-year postoperatively (r = 0.37; p < 0.0001). Total RSTF symptom scores are significantly different in patients with chronic rhinosinusitis compared with those without this disease. The total RSTF symptom scores also correlate with a validated outcome measures instrument.
