<p>Exacerbations and health care resource use among patients with COPD in relation to blood eosinophil counts</p>

Abstract

Blood EOS ≥150/μL cells were associated with increased HCRU and higher exacerbation rates compared with EOS <150 cells/μL, irrespective of MITT use. COPD phenotyping using blood EOS could help identify candidates for additional therapies that target eosinophilic inflammatory pathways.
