A Survey of Corticosteroid Dosing for Exacerbations of Chronic Obstructive Pulmonary Disease Requiring Assisted Ventilation

Abstract

Background: For over 40 years, systemic corticosteroids have been a mainstay of treatment for patients with exacerbations of chronic obstructive pulmonary disease (COPD). Surprisingly, the optimal dosage of corticosteroids is unknown in critically ill patients requiring assisted ventilation, a group with high morbidity and mortality. Methods: We surveyed 39 academic physicians within the United States Critical Illness and Injury Trials Group (USCIITG) and the Prevention and Early Treatment of Acute Lung Injury Trials Network (PETAL) to determine the range of corticosteroid dosages used to treat patients with COPD exacerbations requiring assisted ventilation. We also asked if these physicians believe that a clinical trial is needed to determine the optimal dosage of corticosteroids in this population. Results: Thirty-two physicians (82%) responded to the survey. Usual practice was to start intravenous methylprednisolone at a median dose of 120mg/day (range 40-500mg/day). In the context of a clinical trial, 78% of physicians were comfortable initiating methylprednisolone at a dose as low as 40mg/day. In contrast, physicians were split on the highest acceptable methylprednisolone dose, with 44% comfortable initiating doses as high as 500mg/day, 44% at 240mg/day, and 12% at doses less than 240mg/day. Ninety-four percent of respondents believed that a randomized controlled trial is needed to determine the optimal corticosteroid dose to treat patients with COPD exacerbations requiring assisted ventilation. Conclusions: These results demonstrate sufficient clinical equipoise to support the conduct of a clinical trial to identify the optimal dose of systemic corticosteroids for patients with COPD exacerbations requiring assisted ventilation.
