Asthma patients prefer Respimat Soft Mist Inhaler to Turbuhaler.
Device satisfaction and preference are important patient-reported outcomes to consider when choosing inhaled therapy. A subset of adults (n = 153) with moderate or severe asthma participating in a randomized parallel-group, double-dummy trial that compared the efficacy and safety of 12 weeks' treatment with budesonide delivered via Respimat Soft Mist Inhaler (SMI) (200 or 400 microg bd) or Turbuhaler dry powder inhaler (400 microg bd), completed a questionnaire on patient device preference and satisfaction (PASAPQ) as part of a psychometric validation. As the study used a double-dummy design to maintain blinding, patients used and assessed both devices, rating their satisfaction with, preference for, and willingness to continue using each device. The mean age of patients was 41 years, 69% were female and the mean duration of disease was 16 years. Total PASAPQ satisfaction scores were 85.5 and 76.9 for Respimat SMI and Turbuhaler respectively (p < 0.0001); 112 patients (74%) preferred Respimat SMI and 26 (17%) preferred Turbuhaler. Fourteen subjects (9%) indicated no preference for either inhaler. Willingness to continue using Respimat SMI was higher than that for Turbuhaler (mean scores: 80/100 and 62/100, respectively). Respimat SMI was preferred to Turbuhaler by adult asthma patients who used both devices in a clinical trial setting.
