Purpose: To evaluate clinical outcomes and costs of inhaled corticosteroid (ICS) and systemic corticosteroid combination therapy versus systemic corticosteroid monotherapy for treatment of acute exacerbations of chronic obstructive pulmonary disease (AECOPD). Methods: Hospitalized patients aged 41 to 85 years old who received ≥40 mg/day of systemic prednisone equivalents between April 3, 2017 to July 31, 2017 and April 3, 2018 to July 31, 2018 with a primary discharge diagnosis of AECOPD. Two cohorts were identified: those who received >2 doses of ICS (combination therapy) and those who received ≤2 doses of ICS (monotherapy) while on systemic corticosteroid therapy. Primary outcomes were progression of respiratory support or ≥20% increase in daily dose of systemic corticosteroids. Secondary outcomes were hospital length of stay (LOS), COPD 30-day readmissions, in-hospital mortality, and nebulized budesonide costs. Results: One hundred twenty-eight patients met inclusion criteria. Daily corticosteroid dose increases were similar between the combination and monotherapy cohorts (4% vs. 5%, P = 0.76) as was progression in ventilatory support (12% vs. 8%, P = 0.53). In-hospital mortality (4% vs. 1%, P = 0.36) and COPD 30-day readmissions (16% vs. 9%, P = 0.22) were not significantly different, however, patients in the combination arm had longer lengths of stay (4.8 days vs. 3.9 days, P = 0.04). Total nebulized budesonide costs were $1857 with a mean of $37 per patient stay for combination therapy cohort. Conclusion: Outcomes showed no clinical difference between combination therapy and monotherapy. This study suggests monotherapy may be more cost-effective while providing similar outcomes for the treatment of hospitalized patients with AECOPD.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
