Background Suboptimal inhaler technique is an important reason of poor health outcomes in asthma & COPD patients. Various educational interventions to improve inhaler technique have been developed, yet the key characteristics of successful interventions have not been identified.
Aims We aimed to systematically review RCTs of educational inhalation technique interventions to assess overall effectiveness and key success factors.
Methods The MEDLINE, EMBASE and CINAHL databases were searched for RCTs on educational interventions to improve inhaler technique in asthma and COPD patients. Inclusion eligibility and quality appraisal (Cochrane Collaboration's risk of bias tool) were performed by two independent reviewers. Characteristics of the education (e.g. setting, provider, group size and time), study population, inhaler type, and outcomes were systematically extracted. Regression analyses were performed to identify key characteristics contributing to inhaler technique improvement.
Conclusion This study suggests that educational interventions to improve inhaler technique are generally effective, especially in patients with poor initial technique. However, they should be reinforced over time.
