RATIONALE: Nebulizers are an alternative to handheld devices for inhaled therapies in chronic obstructive pulmonary disease (COPD). Understanding nebulizer utilization patterns is essential to developing therapy guidelines.
OBJECTIVES: We aimed to describe characteristics of nebulizer users versus nonusers and factors associated with baseline nebulizer use and longitudinal uptake.
METHODS: We analyzed the Subpopulations and Intermediate Outcome Measures in COPD Study, a prospective cohort of 2973 participants with or without tobacco use and/or COPD. We used cross-sectional multivariable logistic regression and interval-censored proportional hazard models to analyze factors associated with nebulizer use and uptake among tobacco-exposed participants with preserved spirometry (TEPS) and COPD from enrollment (Visit 1) through 4–7 years of follow-up (Visit 5).
RESULTS: Nebulizer utilization was highest in advanced COPD, 49% of Global initiative for chronic Obstructive Lung Disease (GOLD) Group D participants at baseline. Nebulizer treatments were primarily as-needed short-acting bronchodilators. Baseline nebulizer use was associated with respiratory exacerbations in the prior year (1, odds ratio [OR] 1.81, 95% confidence interval [CI] [1.24, 2.64]; 2, OR 1.86, 95% CI [1.07, 3.22]; 3 or more, OR 1.87, 95% CI [1.07, 3.28]), lower forced expiratory volume in 1 second (FEV1) (OR 2.81 per liter decrease, 95% CI [2.09, 3.77]), COPD Assessment Test (CAT) score >10 (OR 1.89, 95% CI [1.17, 3.03]), 6-minute walk distance (6MWD) (OR 1.03 per 10 meter lower 6MWD, 95% CI [1.02, 1.05]), and a history of asthma (OR 2.41, 95% CI [1.76, 3.30]). Longitudinal uptake was similarly associated with exacerbations, lower FEV1, CAT score >10, and asthma. Patterns were consistent between TEPS and COPD.
CONCLUSION: Nebulizers were predominantly used by participants with frequent exacerbations, high symptom burden, and advanced COPD, and long-acting nebulized medications were underutilized. Randomized controlled trials are needed to compare nebulizers with hand-held devices.
