Inhaler devices for asthma: do we follow the guidelines?

Area of Science:

• Pediatric Respiratory Medicine
• Public Health
• Pharmacology

Background:

• National asthma treatment guidelines exist, yet many children experience persistent symptoms.
• Inappropriate inhaler device use is a potential contributor to uncontrolled childhood asthma.
• Effective asthma management requires adherence to established treatment protocols.

Purpose of the Study:

• To evaluate the prevalence of inappropriate inhaler device use in children with asthma.
• To determine the contribution of incorrect inhaler selection to symptom burden.
• To identify factors influencing appropriate inhaler device utilization.

Main Methods:

• A large-scale questionnaire survey distributed to schoolchildren identified children using asthma inhalers.
• Inhaler devices were classified as age-appropriate or inappropriate based on national guidelines.
• Comparison data were obtained from children attending a hospital asthma clinic.

Main Results:

• 35% of children in schools and 4% in clinics used inappropriate inhaler devices.
• Metered-dose inhalers were frequently used without a spacer, particularly in younger children.
• Both children and parents overestimated the child's ability to correctly use their inhaler.

Conclusions:

• A significant proportion of children receive inhaler devices they are unable to use effectively.
• Prescriptions must align with a child's age and demonstrated ability to use the device.
• Improved communication between primary and secondary care is essential for optimizing childhood asthma management and driving necessary changes in practice.
