PURPOSE: We aimed to compare the clinical characteristics and treatment outcomes in patients with eosinophilic and neutrophilic chronic obstructive pulmonary disease (COPD) exacerbations requiring hospital admission.

METHODS: This was a retrospective and multicenter study between Jan 2010 and Dec 2014. In all, 729 COPD patients with severe COPD exacerbations requiring hospital admission were enrolled in the study via the outpatient clinics or emergency department at 6 university hospitals. Patients were grouped according to the complete blood count: eosinophilic group, >2% peripheral blood eosinophil; neutrophilic group, >65% peripheral blood neutrophil or >10,000 leukocytes. Patients with radiographic evidence of pneumonia, those having lung cancers or admitted due to other medical problems were excluded.
