  • Inhaler Research Workgroup study


    Inhaled medication is the cornerstone of the pharmacological treatment of patients with asthma and COPD. According to the Global Initiative for Asthma (GINA) 70 to 80% of patients have a poor inhaler technique. This leads to poor disease control, hence poor disease outcomes and costs. Even with clear inhalation instructions and regular monitoring by health caregivers, the amount of patients who suffer from serious technique errors remains high. We developed a study design that will lead to answering our main research question: can we improve inhaler technique by a didactic-based teaching method to transfer clear inhaler instructions to patients?


    The workgroup consists of scientists and healthcare professionals from various disciplines and the aim of this workgroup is to find ways to improve inhaler technique in patient with asthma and COPD. We want to evaluate this problem from an interdisciplinary perspective and develop recommendations to improve inhaler technique. 


    1) What is the best instruction method according to the literature to teach complicated (medical) handlings?
    2) What are the experiences and opinions of patients and instructors with inhaler instruction?
    3) What is the effectiveness of our newly developed instruction method?


    1) literature research regarding educational (inhaler) techniques
    2) patient/instructor interviews regarding inhaler technique instructions
    3) formulate a new teaching method for inhaler techniques based on the findings of 1 and 2.
    4) a cluster randomized trial in several countries with different inhaler technique training methods to compare their effectiveness.
