The effect of early goal-directed therapy for treatment of severe sepsis or septic shock: A systemic review and meta-analysis

Abstract

Purpose: To assess the effects of early goal-directed therapy (EGDT) on reducing mortality compared with conventional management of severe sepsis or septic shock. Materials and methods: We included a systemic review, using the Medline and EMBASE. Seventeen randomized trials with 5765 patients comparing EGDT with usual care were included. Results: There were no significant differences in mortality between EGDT and control groups (relative risk [RR], 0.89; 95% confidence interval [CI], 0.79-1.00), with moderate heterogeneity (I-2 = 56%). The EGDT was associated with lower mortality rates when the mortality rate of the usual care group was greater than 30% (12 trials; RR, 0.83; 95% CI, 0.72-0.96), but not when the mortality rate in the usual care group was less than 30% (5 trials; RR, 1.03; 95% CI, 0.92-1.16). The mortality benefit was seen only in subgroup of population analyzed between publication of the 2004 and 2012 Surviving Sepsis Campaign guidelines, but not before and after these publications. Conclusion: This meta-analysis was heavily influenced by the recent addition of the trio of trials published after 2014. The results of the recent trio of trials may be biased due to methodological issues. This includes lack of blinding by incorporating similar diagnostic and therapeutic interventions as the original EGDT trial. (C) 2016 Elsevier Inc. All rights reserved.
