ABSTRACT
Background: Chronic obstructive pulmonary disease (COPD) is a common respiratory condition associated with high morbidity and mortality. A correct diagnosis of COPD can decrease symptoms, reduce frequency and severity of exacerbations, improve health status, improve exercise capacity, and prolong survival. Inhaler devices are mainstay in management of chronic obstructive pulmonary disease and their proper usage requires continuous training. A thorough literature search has shown limited data on the outcome of various techniques and devices used in COPD; hence this study is being done to study the outcome of use of inhalers in patients with COPD following training. Methods: This prospective, observational study was conducted on patients suffering from COPD as per Global Initiative for Chronic Obstructive Lung Disease (GOLD) criteria. The patients were given instructions and training correctly all patients were called after one month and spirometry parameters were assessed after one month. Spirometry and St. George Respiratory Questionnaire was administered to all participants. Results: A total of 60 patients were enrolled in study with the mean age of 49.37±17.65 years. 19 patient suffering from COPD also had concurrent diseases associated. Revolizer was used by 60% of patients. There was a significant (p<0.05) improvement in FEV1 and PEF after 1 month of proper use of inhalation technique. All patients showed a statistically significant (p<0.05) improvement in symptoms score in SGRQ. Conclusion: A significant improvement in FEV1, Ratio of FEV1/FVC and PEF was observed after 1 month, there was also improvement in Quality of life of patients.
