Assessment of regular drug use and inhaler technique skills in asthmatic children

This study aimed to assess the regular use of long-term asthma-control medication and to determine inhaler techniques in asthmatic children.

The study was conducted on asthmatic children aged 6-18 years. Information on rescue and controller medications was given and the proper inhalation technique was demonstrated. One month later, patients and parents were asked to answer a questionnaire on drug use and to demonstrate their inhaler techniques.

One hundred children and/or their parents were interviewed for the study. All of the patients identified long-term asthma-control medications while quick-relief asthma medications were identified by 93% of the patients. Of the patients, 34% described the dose of their quick-relief medication correctly. All steps in the inhalation technique were correctly carried out by 60.6% of patients using a metered-dose inhaler (MDI), 80% of patients using a Turbuhaler, and 58% of patients using a capsule-based dry-powder inhaler (DPI). Of the participants, 73% reported regular use of long-term asthma-control medications. While the mean age of the patients regularly using long-term asthma medications was 9.05±2.5 years, that of patients not compliant with the regular treatment was 10.29±3.26 years (p=0.04). The most common reason for irregular drug use was forgetting to take the drug.

Adherence to long-term asthma-control medications tends to be better in younger patients. Since the most common cause of irregular drug use is forgetting to take the drug, repeated training is necessary to ensure asthma control and the successful treatment of asthmatic children.
