INTRODUCTION AND OBJECTIVES: Stable chronic obstructive pulmonary disease (COPD) caused by biomass smoke (B-COPD) has some differences from tobacco-induced-COPD (T-COPD), but acute exacerbations (AECOPD) have not been well characterized in B-COPD. OBJECTIVE: To compare the incidence, characteristics and outcomes of AECOPD in B-COPD with those of T-COPD. METHODS: A retrospective observational study that included consecutive patients seen at a specialized COPD clinic (2008–2021). The incidence of severe AECOPD that required hospital admission was studied. For the first AECOPD, the following variables were recorded: fever, coexistence of pneumonia, purulent sputum, eosinophil count, neutrophil to lymphocyte ratio, hypercapnia, and respiratory acidosis. Outcome variables were intensive care unit (ICU) admission, length of hospital stay, and mortality within 1 month of hospital admission. RESULTS: Of 1060 subjects, 195 (18.4%) belonged to the B-COPD group and 865 (81.6%) to the T-COPD group. During a follow-up of 67.9 (37.8–98.8) months, 75 (38.4%) patients in the B-COPD group and 319 (36.8%) in the T-COPD group suffered at least one severe AECOPD. The only difference between groups was in a higher risk of ICU admission for the T-COPD group. The incidence, characteristics, and the rest of the outcomes of AECOPD were similar for both groups. CONCLUSION: AECOPD are similar events for B-COPD and T-COPD and should be managed similarly.
