The Impact of Educational Intervention on Patients of Chronic Obstructive Pulmonary Disease Undergoing Exercise and Medication

Introduction Chronic obstructive pulmonary disease (COPD) is a progressive lung disease marked by airflow limitation, impairing functional capacity and quality of life. Education, exercise, and medication are key components of COPD management, yet evidence on their combined impact remains limited. This study aimed to evaluate the impact of an educational intervention, alongside exercise and medication, on respiratory symptoms, exercise capacity, lung function, and quality of life in COPD patients. Method A quasi-experimental study was conducted at Dhaka Medical College Hospital from December 1, 2022, to September 30, 2023. A total of 52 COPD patients aged 40-80 years with mild to moderate disease were enrolled in this study. Patients were purposively allocated into two groups: group A received education, exercise, and medication; and group B received exercise and medication alone. Outcomes measured included dyspnea (mMRC), health status (CCQ), exercise capacity (six-minute walk test (6MWT)), oxygen saturation (SpO₂), and lung function (forced expiratory volume (FEV)₁/forced vital capacity (FVC)). Pre-post changes were analyzed using paired t-tests, and between-group comparisons were made using independent t-tests. Results Both groups showed significant improvements from baseline; however, group A demonstrated consistently superior outcomes. After 24 weeks, group A had significantly lower dyspnea scores (1.59 ± 0.50 vs 2.24 ± 0.83; p = 0.001) and better CCQ scores (3.04 ± 0.32 vs 3.31 ± 0.36; p = 0.006). Functional capacity improved more in group A (6MWT: 551.7 ± 32.7 m vs 526.8 ± 37 m; p = 0.01). Oxygen saturation was higher (97.2 ± 0.56% vs 96.2 ± 0.91%; p < 0.001), and pulmonary function improved more notably (FEV₁/FVC: 65.97 ± 2.65 vs 61.78 ± 4.17; p < 0.001) in group A compared to group B. Conclusion Educational intervention combined with exercise and medication significantly improved symptoms, functional capacity, oxygenation, and lung function in COPD patients. Structured education programs are recommended as an integral part of COPD management to enhance patient outcomes.
