Information from a new large study has increased our confidence that five days of oral corticosteroids is likely to be sufficient for treatment of adults with acute exacerbations of COPD, and this review suggests that the likelihood is low that shorter courses of systemic corticosteroids (of around five days) lead to worse outcomes than are seen with longer (10 to 14 days) courses. We graded most available evidence as moderate in quality because of imprecision; further research may have an important impact on our confidence in the estimates of effect or may change the estimates. The studies in this review did not include people with mild or moderate COPD; further studies comparing short-duration systemic corticosteroid versus conventional longer-duration systemic corticosteroid for treatment of adults with acute exacerbations of COPD are required.
We based assessment of the efficacy of short (seven days or less) compared to longer duration (more than seven days) systemic corticosteroid therapy for acute exacerbations of COPD in this review on four of the seven included studies for which data were available. Two studies were fully published and two were published as conference abstracts but trialists were able to supply data requested for the review.The finding in this review that there is no significant increase in treatment failure with shorter systemic corticosteroid treatment for seven days or less for acute exacerbations of COPD, does not give conclusive evidence to recommend change in clinical practice due to a wide confidence interval around the estimate of effect. The four studies which contributed to the meta-analysis were of relatively low quality and five of the seven studies were not published as full articles. Thus there are insufficient data to allow firm conclusions concerning the optimal duration of corticosteroid therapy of acute exacerbations of COPD to be drawn.

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.
