The questionnaire responses and medications prescribed to the simulated patients by the doctors in the different groups were analyzed and compared.Results: (1) This study surveyed 109 doctors who made prescription decisions for 872 simulated COPD patients. (2) The results of the questionnaire revealed that the percentages of LAMA, LAMA/LABA and triple therapies that could be prescribed in community health care centers were 40.6%, 25%, and 34.4%, respectively. More than 60% of the physicians in the CHC and SH groups prescribed ICS/LABA as an initial regimen for maintenance therapy. (3) Triple therapy accounted for the highest proportion of prescriptions at 49%, followed by dual bronchodilator therapy (29.6%), whereas LAMA monotherapy represented the smallest share, with only 4.9% of prescriptions. Notably, ICS/LABA combination therapy represented a clinically relevant proportion of prescriptions (14.3%). A total of 58.9% of the 170 simulated COPD patients without asthma in the current study were prescribed triple therapy by their physicians. Approximately 60% of the COPD patients in Groups A and B were prescribed triple therapy as an initial treatment regimen, despite blood EOS counts of 100– 300 cells/μL in both groups.Conclusion: Although most respiratory physicians follow guidelines for the choice of initial therapy for COPD, there are still irregularities in the use of triple therapy. A clinically relevant percentage of physicians, especially community physicians, selected ICS+LABA as the initial treatment choice. These practice irregularities should be the focus of future guidelines for promotion and education.Keywords: COPD, treatment, cross-sectional survey, multivariate discrete choice modeling
