Abstract

Objective
To examine the relationships between inhaler satisfaction, treatment compliance and health status in patients with chronic obstructive pulmonary disease (COPD).

Methods
In a large, multinational, cross-sectional, real-world survey, respiratory specialists and primary care physicians provided information on six consecutive patients with COPD, who were then asked to complete a questionnaire. Physician-assessed compliance was scored (5-point Likert scale) and patients rated overall satisfaction with their maintenance inhaler (7-point Likert scale). Health status assessments included frequency of exacerbations and hospitalizations due to exacerbations in the past 12 months.

Results
The analysis included 1443 patients (71.8% male; mean age 65.2 years). Patients’ overall satisfaction with their inhaler was significantly associated with treatment compliance (χ2–df = 89.7; p < 0.001). Male gender (χ2–df = 2.9; p < 0.05) and fewer maintenance drugs (χ2–df = 17.7; p < 0.001) were also associated with compliance; age and breathlessness severity were not. Attributes influencing inhaler satisfaction mainly related to durability, ergonomics and ease of use. Small but statistically significant associations were observed between increasing treatment compliance and fewer exacerbations (R2 = 0.037; p < 0.001) and fewer hospitalizations due to exacerbations (R2 = 0.025; p < 0.001). There was a direct association between inhaler satisfaction and fewer exacerbations (R2 = 0.03; p < 0.001).

Conclusions
Treatment compliance appears to be modestly associated with inhaler satisfaction, better health status and less frequent COPD exacerbations, although other factors are also likely to be involved. Durability, ergonomics and ease-of-use are inhaler attributes that influence patient satisfaction.
