Evaluation of inhaler technique among patients with asthma and COPD in Yemen

OBJECTIVES: This study aimed to evaluate metered-dose inhaler (MDI) technique among Yemeni patients with asthma and chronic obstructive pulmonary disease (COPD), and to investigate factors that affect correct use of MDIs. METHODS: A cross-sectional study was conducted in five pharmacies in the Yemeni capital city of Sana'a to evaluate MDI technique among adult patients with asthma and COPD and to investigate factors that influence proper application of MDI techniques. RESULTS: Of 49 patients, 47 (95.9%) were males and two (4.1%) were females. The mean age of the patients was 52.90 ± 6 years (range: 43–64 years). This study showed that only nine patients (18.4%) demonstrated good knowledge of MDI techniques; two patients (4.1%) demonstrated moderate knowledge; the majority of patients (77.6%) showed poor knowledge regarding correct MDI technique. Previous training regarding MDI technique was the only factor that affected appropriate use of MDIs. CONCLUSION: The majority of patients in this study could not use their MDI appropriately. Thus, patients should be educated regarding correct MDI technique upon dispensing of inhaler medications. Training and educational intervention programs may contribute to improved MDI technique among patients.
