What this Trial Is About
This research aims to evaluate spirometry results in patients with severe asthma who have undergone bronchial thermoplasty. The study is retrospective and will review existing medical records from two medical centers to analyze lung function changes after the procedure. The main goal is to assess improvements in lung function, specifically in forced expiratory volume (FEV1) and forced vital capacity (FVC), one year after treatment. The study focuses on patients who have completed the bronchial thermoplasty procedure, which involves three separate sessions following recommended protocols. Data collected will include age, height, sex, weight, medical and smoking history, as well as spirometric measurements taken before and after the thermoplasty and bronchodilator use. The data comes from records at OU Medical Center and St. Francis Hospital. Participants in this study will not be actively enrolled since it is a retrospective review. Researchers will analyze available spirometry data and other clinical information from past patients. The primary outcome measured is the change in prebronchodilator FEV1 and FVC one year after thermoplasty. Secondary outcomes include changes in postbronchodilator lung function and responsiveness to bronchodilators. No new treatments or visits are required as all data is collected from past records.
