Interventions to improve inhaler technique for people with asthma

Area of Science:

• Respiratory Medicine
• Clinical Trials
• Public Health

Background:

• Asthma is a prevalent chronic respiratory condition globally.
• Inhalers are crucial for asthma management, yet incorrect usage is common.
• Evaluating interventions for inhaler technique is vital for improving patient outcomes.

Purpose of the Study:

• To assess the effectiveness and safety of interventions designed to improve inhaler technique in individuals with asthma.
• To determine the impact of these interventions on clinical outcomes.

Main Methods:

• A systematic review and meta-analysis of randomized controlled trials (RCTs) was conducted.
• Searches included major databases and trial registries up to November 2016.
• Studies compared inhaler technique interventions against control or alternative interventions.

Main Results:

• Twenty-nine RCTs involving 2210 participants were included, with evidence quality rated as low to moderate.
• Enhanced education and multimedia training improved inhaler technique in adults, but benefits for children were less clear.
• While some improvements in asthma control and quality of life were observed, consistent and significant clinical benefits were not demonstrated.

Conclusions:

• Interventions to improve inhaler technique show potential but are hampered by varied methods and limited reporting of clinical outcomes.
• Current evidence does not consistently support significant clinical improvements from inhaler technique interventions.
• Further research is needed to identify optimal intervention strategies and their impact on clinical outcomes in asthma management.
