Background: Correct inhaler use is essential for symptom control in chronic obstructive pulmonary disease (COPD); however, incorrect technique remains common and may reduce treatment effectiveness. Aims: To evaluate nurse-led inhaler education’s effects on technique, dyspnoea and severity in COPD. Methods: A randomised controlled trial included 90 COPD outpatients recruited between December 2022 and May 2023, assigned to an intervention group ( n = 45) receiving nurse-led inhaler training or a control group ( n = 45) receiving routine care. Inhaler technique, dyspnoea (modified Medical Research Council Dyspnoea Scale) and disease severity (COPD Assessment Test, CAT) were assessed at baseline and 4 weeks later. Data were analysed using independent-samples t ‑tests, repeated‑measures analysis of variance, Pearson correlation and chi‑square tests. Results: Baseline characteristics were comparable between groups ( p > 0.05). The intervention group showed significantly greater improvement in inhaler technique ( F = 62.416, p < 0.001), lower dyspnoea scores ( F = 38.029, p < 0.001) and reduced CAT scores ( p < 0.001) than controls. Conclusions: Structured nurse-led inhaler education improves inhaler technique and clinical outcomes in COPD. Findings support nursing theories of patient education and self‑management, underscoring nurses’ role in chronic disease care. Policies embedding standardised, competency‑based inhaler education into respiratory nursing practice are recommended to strengthen COPD management.
