Impact of a Brief Educational Intervention Inhaler Technique Study

Introduction: Incorrect inhaler technique is a common cause of poor disease control in asthma and COPD patients, leading to reduced drug delivery and increased morbidity. Brief educational interventions may improve technique and clinical outcomes. Materials and Methods: A pre–post interventional study was conducted on 60 asthma/COPD patients using metered-dose inhalers (MDI) or dry powder inhalers (DPI) at Shri BM Patil Medical College Vijayapura. Baseline inhaler technique was assessed using standardized checklists. A brief educational intervention including demonstration, video, and leaflet was provided. Reassessment was done after 7 days. Statistical analysis included paired t-test and Wilcoxon test. Result: Baseline correct technique was observed in only 35–40% of patients. Post-intervention, inhaler technique scores improved significantly (MDI: 4.1 ± 1.5 to 7.1 ± 0.9; DPI: 3.2 ± 1.2 to 5.4 ± 0.6; p < 0.05), with 80–85% achieving correct technique. Symptom scores also improved significantly, with ACT increasing (16 ± 3 to 21 ± 2) and CAT decreasing (22 ± 5 to 16 ± 4) (p < 0.01). Conclusion: A brief educational intervention significantly improves inhaler technique and symptom control in asthma and COPD patients and should be incorporated into routine clinical practice.
