Abstract
BACKGROUND: Patients with chronic rhinosinusitis (CRS) often have comorbid asthma. Prior studies have not examined the impact of CRS or endoscopic sinus surgery (ESS) upon asthma quality-of-life (QOL) and asthma control using validated outcome metrics.
METHODS: Patients with CRS, both with and without polyps, and comorbid asthma completed the Mini-Asthma QOL Questionnaire (miniAQLQ) and Asthma Control Test (ACT) at baseline and 6 months postoperatively as part of a multi-institutional, prospective study.
RESULTS: Baseline metrics were available on 86 patients. Patients undergoing ESS reported improved miniAQLQ (0.5 [SD±1.1], 95%CI: 0.2-0.7; p=0.002) and ACT scores (1.3 [±4.1], 95%CI: 0.2-2.4; p=0.025). Uncontrolled baseline asthma (ACT<20) was present in 51% of patients undergoing ESS. In uncontrolled patients, ESS resulted in a minimal clinically important difference 57% of the time for miniAQLQ scores (>0.5 points) and 50% of the time for ACT scores (>3.0 points). After adjustment with linear regression, baseline miniAQLQ scores were worse in patients with comorbid allergy (p=0.045) and chronic obstructive pulmonary disease (COPD; p=0.015). Adjusted baseline ACT scores were worse in patients with COPD (p=0.004). Covariates associated with changes in miniAQLQ scores after ESS were preoperative corticosteroid dependency (p=0.011) and change in total SNOT-22 score (p=0.010). Covariate associated with significantly less improvement in ACT scores was obstructive sleep apnea (p=0.016).
CONCLUSIONS: Patients with CRS often present with uncontrolled asthma, and ESS improves both miniAQLQ and ACT. Approximately half of patients with uncontrolled asthma improve after ESS, yet there are few CRS-specific factors associated with asthma QOL or control or ESS outcomes.
