Abstract
Background: Chronic obstructive pulmonary disease (COPD) is a global burden because of its prevalence, high treatment costs, and gradual progression to disability. Inhaler is one of the essential factors contributing to the successful treatment of chronic obstructive pulmonary disease.This study was carried out to determine the proportion of good inhaler technique and the associated factors in this group of subjects.
Methods: Among the patients who applied to the respiratory department between October 2020 and May 2021, 101 patients with COPD were recruited who met the criteria of the study. The cross-sectional study evaluated the inhaler technique using a checklist adapted for each device model used by COPD patients by analyzing 147 video - recorded demonstrations.
Results: Overall, 21.8% of patients did not make any critical errors with all device models. In which the correct usage rate of pMDI, pMDI combined chamber, Respimat®, Respimat® combined chamber, Turbuhaler®, Breezhaler®, Accuhaler® was 15.2%, 62.5%, 34.8%, 33.3%, 18.2%, 21.7% and 100%, respectively. When evaluating in detail, “breathe out all the way” and “hold breath within 5 seconds” were steps that were often taken wrong. Low mMRC score (OR = 5.04, CI 95% 1.19 - 1.30), guided within 3 last months (OR = 3.87, CI 95% 1.13 - 13.22) and used to be guided by medical staff (OR = 6.3, CI 95% 1.77 - 22.53) were the factors associated with correct inhaler technique.
Conclusions: In summary, the proportion of the COPD inpatients with the good inhaler technique was relatively modest. Therefore, it is crutial to pay more attention to the process of using the inhaler, notably at each follow - up visit to optimize treatment
