Dose adherence was predominantly influenced by COPD health literacy, mMRC grading, duration of COPD, utilisation of support and marital status. Inhalation technical standardisation was substantially limited by age, mMRC grading, social support, mode of residence, number of acute exacerbations in the past year and literacy.
