Abstract

Purpose

Low-dose steroids may reduce the mortality of severely ill patients with septic shock. We sought to determine whether exposure to stress-dose steroids during and/or after cardiopulmonary resuscitation is associated with reduced risk of death due to postresuscitation septic shock.

Methods

We analyzed pooled, individual patient data from two prior, randomized clinical trials (RCTs). RCTs evaluated vasopressin, steroids, and epinephrine (VSE) during resuscitation and stress-dose steroids after resuscitation in vasopressor-requiring, in-hospital cardiac arrest. In the second RCT, 15 control group patients received open-label, stress-dose steroids. Patients with postresuscitation shock were assigned to a Steroids (n = 118) or No Steroids (n = 73) group according to an “as-treated” principle. We used cumulative incidence competing risks Cox regression to determine cause-specific hazard ratios (CSHRs) for pre-specified predictors of lethal septic shock (primary outcome). In sensitivity analyses, data were analyzed according to the intention-to-treat (ITT) principle (VSE group, n = 103; control group, n = 88).

Results

Lethal septic shock was less likely in Steroids versus No Steroids group, CSHR, 0.40, 95% confidence interval (CI), 0.20–0.82; p = 0.012. ITT analysis yielded similar results: VSE versus Control, CSHR, 0.44, 95% CI, 0.23–0.87; p = 0.019. Adjustment for significant, between-group baseline differences in composite cardiac arrest causes such as “hypotension and/or myocardial ischemia” did not appreciably affect the aforementioned CSHRs.

Conclusions

In this reanalysis, exposure to stress-dose steroids (primarily in the context of a combined VSE intervention) was associated with lower risk of postresuscitation lethal septic shock.
