Abstract

GOLD 2022 recommends using blood eosinophils counts threshold as 300 cells/µL to be a criterion to initiate inhaled corticosteroids treatments for chronic obstructive pulmonary disease (COPD) patients to improve clinical outcomes. This cross-sectional study on 200 COPD patients was to determine the rate of high blood eosinophils counts in COPD patients with the cut-off 300 cells/µL and identify related factors. Overall, there are 41.5% COPD patients with high blood eosinophils counts. Factors related to high blood eosinophils counts are previous hospitalized exacerbations with OR = 1.93 (95% CI: 1.06 - 3.51), obesity with OR = 3.25 (95% CI: 1.32 - 8.02) and currently smoking with OR = 2.23 (95% CI: 1.23 - 4.05).
