Abstract

Objectives: Inhalation technique plays a very important role in asthma treatment and is related to disease control. The study aimed to determine the proportion of asthmatic patients using the Turbuhaler device (AstraZeneca) improperly and to find the relationship between asthma symptom control and improper steps of using Turbuhaler. Subjects and methods: Cross-sectional study on 200 outpatient asthma patients using Turbuhaler. All patients were assessed for asthma control according to GINA 2021 and ACT scores. Turbuhaler usage is evaluated according to a 9-step checklist and whistle device. Results: The rate of incorrect use of the Turbuhaler was 74.0% and the rate of incorrect at least one essential step was 37.5%. Improper use of Turbuhaler increased the risk of poor asthma symptom control according to GINA (adjusted OR=3.30; 95% CI 1.50-7.30; p=0.003) and the ACT scale (adjusted OR =1.43; 95% CI 1.11-1.84; p=0.006). Failure to hold breath for at least 5 seconds after inhalation was the only error independently associated with poorer asthma symptom control according to GINA (adjusted OR=2.24; 95% CI 1.10-4.58; p= 0.027). Conclusion: The incorrect technique of using Turbuhaler in asthmatic patients accounts for a high proportion and is independently associated with poor asthma symptom control.
