The long-term goals of asthma treatment are to achieve well control of symptoms and to minimize the future risk of asthma exacerbations (AEs). Asthma is a heterogeneous disease with various responses to treatment and clinical outcomes. AEs are a prominent feature of severe asthmatics; however, frequent AEs have also been reported in mild asthmatics.~This is a prospectively designed observational study to identify predictors for patients with frequent AEs among adult asthmatics by analyzing medical big data of electronic medical records (EMR), which will provide an insight in the long-term management of adult asthmatics in real-world practice.
This study is a single-center, retrospective, cross-sectional study. It plan to investigate the predictors for asthma exacerbation in long term follow up real world management with analyzing big data of electronic medical records (EMR).
