Response shift in quality of life after endoscopic sinus surgery for chronic rhinosinusitis.

ABSTRACT:

Importance

Patient-reported measures are designed to detect a true change in outcome, but they are also subject to change from biases inherent to self-reporting: changing internal standards, changing priorities, and changing interpretations of a given instrument. These biases are collectively known as "response shifts" and can obscure true change after medical interventions.

Objective

To determine the presence of response shifts in patients with chronic rhinosinusitis (CRS) after endoscopic sinus surgery.

Design, setting, and participants

Multisite, prospective, observational cohort study conducted at academic tertiary care centers between February 2011 and May 2013. Study participants comprised a population-based sample of 514 adults (age ≥18 years) with CRS, who ele
