Özet
Objectives: Inhaled therapy is the treatment of choice for obstructive lung diseases such as asthma and chronic obstructive pulmonary disease (COPD). However, the maximum benefit from such therapy depends on the correct use of inhaler devices. In this study, our primary aim was to evaluate inhaler techniques in patients with asthma and COPD in order to identify common errors. In addition, we investigated the effect of various parameters on the rate of inhaler misuse. Methods: We enrolled a total of 300 asthma/COPD patients, who presented at the Chest Diseases and Family Medicine Outpatient Clinics of a tertiary hospital located in Ankara, Turkey. We used a face-to-face survey that included questions about sociodemographic features and inhaler therapy. Subsequently, we requested patients to demonstrate how they use their inhalers and assessed their inhalation technique according to checklists. Results: Of the 300 patients, 70.2% used their inhaler drugs incorrectly. The rate of misuse among metered dose inhaler (MDI) users was significantly higher than those using dry powder inhalers (DPIs) (77.6% vs 64%; p = 0.002). When DPI devices were analyzed, the rates of misuse were significantly higher in Handihaler users (p = 0.012) and Diskus inhaler users (p = 0.009) when compared to Sanohaler users. Gender, type of disease (asthma/COPD), duration of inhaler use, and duration of illness had no impact on the rate of misuse. However, an advanced age (>60 years old), a level of education lower than high school, and the use of MDI were all identified as factors associated with misuse. The most common mistake was ‘failing to breath out before inhalation’ for all types of devices (for MDI: 66.7%, and for DPI: 71.1–82.8%). Conclusions: The rate of inhaler drug misuse was high. The identification of factors associated with misuse could provide information to implement appropriate actions to reduce the rates of misuse.
