Prospective study reveals superior reliability for duration-based surveys in chronic sinusitis, indicating an effective tool for tracking quality of life.
Accurate assessment of patient outcome after sinus surgery requires the collection of valid and reliable data. Symptom‐based surveys were administered in a prospective manner to 104 patients with chronic sinusitis, Test‐retest reliability for the Chronic Sinusitis Survey based on duration of symptoms (0.86, P <.0001) was superior to that for a similar survey based on severity of symptoms (0.57, P <.0001). Results of the Chronic Sinusitis Survey also correlated significantly with subscales of a general health assessment in the extent to which chronic sinusitis limits physical activity (0.40, P <.01), interferes with work or other activities (0.36, P <.01), and affects patient perception of bodily pain (0.46, P <.001). The Chronic Sinusitis Survey is an efficient and reliable method to follow health status and health‐related quality of life outcomes in patients with chronic sinusitis.
