Background: Asthma and chronic obstructive lung disease (COPD) together constitute a huge burden on healthcare all around the world. Treatment of these patients is largely dependent on the way the inhalation devices are used. This study aimed at measuring the impact of rectification of inhalation technique on quality of life and severity of obstruction in patients with asthma and COPD. Materials and Methods: A total of 45 asthma (partly controlled) and 38 patients with COPD (categories B and C) were enrolled after applying optimal exclusion criteria. These patients underwent Asthma Control Test (ACT)/COPD Assessment Test (CAT) questionnaire as a measure of quality of life and forced expiratory volume in one second (FEV1) as a measure of severity of obstruction at 0 and 4 weeks, respectively. Results: In asthmatics, the mean FEV1 improved from 2.0 to 2.15 L after 4 weeks of technique correction (P < 0.001). In addition, the mean ACT scores improved from 18.0 to 20.75 (P < 0.001). In patients with COPD, the mean FEV1 improved slightly from 1.54 to 1.56 L after 4 weeks of technique correction (P = 0.28). In addition, the mean CAT scores improved from 21.86 to 19.83 (P < 0.001). Conclusion: Demonstration of correct inhalation technique should be an indispensible part of the treatment prescription of patients with obstructive airway disease. This simple and important task can be undertaken at the level of primary care physicians in a community-based setting to improve patient compliance.
