Blood Eosinophil Guided Versus Usual Care In The Management Of Mild To Moderate Asthma at Primary Care (BEAM)
Trial Parameters
Brief Summary
The aim of this study is to evaluate usual care versus biomarker-directed care (using blood eosinophil counts) for the management of asthma patients in primary care setting. The study hypothesizes that BEC is a valuable biomarker that can guide asthma treatment, and result in reduction in asthma exacerbations, better symptom control and improvement in quality of life compared to usual arm in mild to moderate asthma patients in the primary care setting. Researchers would compare using blood eosinophil count guided to usual care to see if biomarker-directed asthma treatment and management
