Evaluation of Systemic Corticosteroids in Patients With an Acute Exacerbation of COPD and a Diagnosis of Pneumonia

Background: Chronic obstructive pulmonary disease (COPD) and pneumonia are leading causes of morbidity and mortality and are frequently comorbid. Studies of systemic corticosteroids in pneumonia have shown conflicting outcomes, whereas studies in acute exacerbations of COPD (AECOPD) have shown significant benefits. No studies have evaluated systemic corticosteroids in patients with both an AECOPD and pneumonia. Purpose: To evaluate the use of systemic corticosteroids in patients with both an AECOPD and pneumonia. Patients and Methods: Patients with a diagnosis of both COPD or obstructive chronic bronchitis with exacerbation and pneumonia admitted to the University of Colorado Hospital between July 1, 2012 and May 20, 2016 were retrospectively evaluated. Patients who received systemic corticosteroids were compared to those that did not. The primary outcome was length of hospital stay (LOHS). Secondary outcomes were in-hospital treatment failure, a composite of intensive care unit (ICU) admission, ventilation, and escalation of steroid therapy, 30-day AECOPD or pneumonia readmission, and 30-day mortality. Results: A total of 138 patients were included-89 in the steroid group and 49 in the non-steroid group. No significant differences in baseline characteristic were noted. No difference was seen in mean LOHS (4.7 +/- 3.2 versus 4.2 +/- 2.1 days, p=0.27), in-hospital treatment failure (7% versus 4%, p=0.72), 30-day readmission or 30-day mortality between the steroid and non-steroid groups, respectively. There was a difference in mean LOHS for patients with severe pneumonia between the steroid and non-steroid groups (6.0 +/- 4.0 versus 4.3 +/- 1.8; p=0.03). Conclusions: This study suggests that systemic corticosteroids may not provide a clinical benefit to patients with an AECOPD and pneumonia.
