Critical Errors in Inhaler Technique Among Patients With Asthma and COPD: A Cross-Sectional Study in a Real-World Setting

Background

The correct use of inhalation devices is essential for achieving adequate control of asthma and COPD; however, critical errors in inhalation technique are frequent and substantially reduce treatment effectiveness. This study's objective was to evaluate the prevalence of inadequate inhalation technique among patients with asthma and COPD and to identify the most common critical errors and the factors associated with incorrect use.
