Comparison of correct technique and preference for Spiromax®, Easyhaler® and Turbuhaler®: a single-site, single-visit, crossover study in inhaler-naïve adult volunteers
Background: Many patients do not use inhalers correctly. Inhalers associated with good technique have the potential to improve symptom control and are often preferred by patients. Methods: Inhaler-naïve, adult volunteers were randomized to use empty Spiromax®, Easyhaler®, and Turbuhaler® dry powder...

| description | Background: Many patients do not use inhalers correctly. Inhalers associated with good technique have the potential to improve symptom control and are often preferred by patients. Methods: Inhaler-naïve, adult volunteers were randomized to use empty Spiromax®, Easyhaler®, and Turbuhaler® dry powder inhalers (DPIs) in one of six possible sequences in this single-site, single-visit, crossover study conducted in Sweden. Randomization was stratified by age and gender. Participants attempted to use each device intuitively (no instructions) and after reading the instructions for use from the patient information leaflet. Device preference was surveyed after using all devices. Mastery of device handling (i.e. dose preparation) or inhalation was defined as having no healthcare-professional-observed errors. The primary endpoint was mastery of device handling after reading the instructions. Results: More participants mastered device handling with Spiromax vs Easyhaler or Turbuhaler, both intuitively (44%, 0%, and 10%, respectively) and after reading the instructions (99%, 56%, and 81%, respectively). Fewer participants had ≥1 device-handling error with Spiromax than with the other devices. The percentage of participants still showing inhalation errors after reading the instructions ranged between 21% for Spiromax and 40% for Easyhaler. After reading instructions, mastery of handling and inhalation was numerically lower among older (aged >60 years) vs younger participants across all devices. Most participants preferred Spiromax for device handling (59%) and intuitiveness/ease of use (61%). Conclusion: These findings highlight that important differences exist between DPI devices, which could have implications for disease control when selecting a device for a patient. |
