Demographic and COPD-related characteristics were collected in baseline.Results: In baseline, after adjusting for age, dust exposure duration positively correlated with number of acute exacerbation (AE) frequency in the last year. There were close associations among COPD Assessment Tool (CAT) score, modified Medical Research Council Dyspnea Scale (mMRC) grade, number of AE, and pre-FEV1 value. Of 296 participants originally recruited, 213 participants finished the 2-year follow-up for adherence. 122 (57.28%) were non-adherent to inhaled therapy. The most common reason for non-adherence was “relief of symptoms after short-term controller medication use” (53.28%). Patients who were non-adherent reported higher body mass index (BMI), less AE events in the last year, higher pre-FEV1 value, higher post-FEV1 value and low CAT, mMRC scores compared to adherent in baseline. High pre-FEV1 value (OR = 1.04, CI = 1.018– 1.064) and low mMRC scores (OR = 0.406, CI = 0.214– 0.771) were risk factors found associated with non-adherence.Conclusion: A majority of pneumoconiosis patients complicated with COPD have suboptimal inhaled therapy adherence. Evidence-based, adherence-enhancing interventions should be targeted on less severe subjects.Keywords: adherence, inhaled therapy, pneumoconiosis, COPD |
