Background: Proper inhaler technique is crucial for effective asthma management. Incorrect usage may lead to suboptimal drug delivery, increased exacerbations, and poor disease control. This study evaluates the impact of inhaler technique on clinical outcomes in asthma patients. Materials and Methods: A total of 200 asthma patients were enrolled in this prospective observational study. Participants were divided into two groups based on their inhaler technique: correct (n=100) and incorrect (n=100). Inhaler technique was assessed using a standardized checklist. Clinical outcomes, including symptom control (measured by the Asthma Control Test, ACT), exacerbation rate, and peak expiratory flow rate (PEFR), were recorded over a six-month follow-up period. Data were analyzed using SPSS software, with a significance level set at p<0.05. Results: Patients with correct inhaler technique demonstrated significantly better asthma control, with a mean ACT score of 21.3 ± 3.2 compared to 16.7 ± 3.8 in the incorrect technique group (p<0.001). The exacerbation rate was lower in the correct technique group (1.2 ± 0.5 per patient per year) than in the incorrect technique group (2.8 ± 0.7, p<0.01). Additionally, PEFR values were significantly higher in patients with proper inhaler use (310 ± 45 L/min vs. 265 ± 40 L/min, p=0.002). Conclusion: Inhaler technique significantly influences asthma control and clinical outcomes. Patients with correct technique exhibit better symptom control, fewer exacerbations, and improved lung function. Educational interventions to enhance inhaler technique should be incorporated into routine asthma management.
