Improvement in Inhaler Techniques After Training and Counseling in Patients With Chronic Obstructive Pulmonary Disease or Asthma.

Background Chronic respiratory diseases such as chronic obstructive pulmonary disease (COPD) and asthma significantly impair quality of life and impose a substantial burden on healthcare systems. Proper inhalation technique is important for effective management of these diseases, yet remains poorly performed by many patients. This study evaluated the impact of structured counseling and training sessions on inhaler use among patients with COPD and asthma, aiming to enhance technique correctness and disease control. Methodology This cross-sectional study analyzed 150 patients with asthma and COPD who fulfilled the inclusion criteria for inhalation techniques. Patients were counseled regarding the proper seven-step inhalation technique for each inhaler type [metered-dose inhaler (MDI), MDI with spacer, and dry powder inhaler (DPI)] through practical demonstration at baseline visits. Correct use of inhalers was assessed by a predefined checklist for each inhaler device at the baseline visit and after three months. The correctness of the inhalation technique was evaluated by scoring each of the seven steps. The disease control assessment was done using the COPD assessment test (CAT) and asthma control test (ACT) at the baseline visit and after three months. Results In this study of 150 patients, there were 97 (64.7%) males and 53 (35.3%) females. In total, 67 (44.7%) were diagnosed with asthma and 83 (55.3%) with COPD. The mean age was 45.33 ± 12.62 years. Post-counseling improvements in inhaler technique were marked, with MDI users enhancing their technique score from an average of 4.4 to 6.1, MDI with spacer from 4.56 to 6.26, and DPI from 4.92 to 6.24 (p < 0.001 for all). Disease control also showed significant gains; CAT scores decreased for MDI users from 23.4 to 20.5, MDI with spacer from 23.92 to 20.96, and DPI from 24.89 to 21.96. Concurrently, ACT scores increased for MDI users from 16.4 to 18.0 (p = 0.002), MDI with spacer from 17.29 to 19.04, and DPI from 16.42 to 18.37 (p < 0.001 for both), reflecting substantive advances in managing COPD and asthma symptoms. Furthermore, patients with primary education exhibited a significant boost in technique mastery post-counseling (p < 0.001), underscoring the potential of well-crafted counseling to transcend educational barriers in promoting effective inhaler use. Conclusions Post-counseling, inhaler technique improved significantly across all types, with MDI with spacer users demonstrating the most progress. Technique scores increased notably (p < 0.001), and disease control scores for COPD and asthma, measured by CAT and ACT, also showed significant improvements (p < 0.001). Remarkably, primary education level participants exhibited substantial technique gains post-intervention, emphasizing the effectiveness of counseling irrespective of initial educational status in enhancing inhaler use and disease management.
