Background |
To assess the level of asthma control achieved with budesonide/formoterol in Chinese patients with asthma, based on the Global Initiative for Asthma (GINA) definition and Asthma Control Test (ACT) score.
Methods |
This multicenter, cross-sectional study (NCT01785901) evaluated asthma control levels in Chinese patients receiving physician-prescribed budesonide/formoterol treatment. Adults with a diagnosis of asthma ≥6 months and receiving budesonide/formoterol treatment ≥3 months before screening were consecutively enrolled. Data including medical and medication history were collected using face-to-face questionnaires and physical examinations during a single visit.
Results |
A total of 1483 asthma out-patients from 27 medical centers were enrolled; 217 (14.6%) were treated with budesonide/formoterol using a fixed-dose strategy and 1266 (85.4%) with the SMART (Symbicort® Maintenance And Reliever Therapy) strategy. According to GINA criteria, asthma was controlled in 58.6% (95% CI: 56.1%–61.1%) of patients and was either controlled or partly controlled in 94.1% (95% CI: 92.8%–95.3%) of patients. According to ACT score, asthma was completely controlled in 22.4% (95% CI: 20.3%–24.6%) of patients and was either completely or well controlled in 83.3% (95% CI: 81.4%–85.2%) of patients. Multivariate logistic regression analysis revealed that a >5-year history of asthma and an age of >50 years were factors associated with lower levels of asthma control.
Conclusions |
This study demonstrated high levels of asthma control (GINA: controlled and partly controlled and ACT: completely and well controlled) in Chinese patients with asthma treated with budesonide/formoterol. Greater age and a longer disease history were associated with lower levels of asthma control.
