I read with great interest the cross-sectional study data reported by Patil et al1 about generalizable estimates, admission characteristics, and risk factors for in-hospital mortality in patients admitted for acute exacerbation of chronic obstructive pulmonary disease (COPD). The authors comment that age, sex, median income, comorbid illnesses, nonroutine admissions, and insurance status have a bearing on mortality during hospitalization. The relationship between long-term use of inhaled corticosteroids (ICSs) and systemic corticosteroids on in-hospital mortality was not studied.
