How Robust are the Evidences that Formulate Surviving Sepsis Guidelines? An Analysis of Fragility and Reverse...

Area of Science:

• Critical Care Medicine
• Clinical Trial Methodology
• Evidence-Based Medicine

Background:

• The Surviving Sepsis Campaign (SSC) provides critical guidelines for managing sepsis and septic shock.
• Assessing the robustness of evidence underpinning clinical guidelines is essential for reliable patient care.
• Randomized controlled trials (RCTs) are the cornerstone of evidence-based medical guidelines.

Purpose of the Study:

• To evaluate the robustness of RCTs used in the 2016 SSC guidelines.
• To quantify the fragility and reverse fragility of RCTs informing sepsis management.
• To determine if statistically significant or nonsignificant results impact the robustness of evidence.

Main Methods:

• Analysis of 100 RCTs meeting inclusion criteria (parallel, 2-group, 1:1 allocation, dichotomous outcome).
• Calculation of median fragility index for RCTs with statistically significant outcomes.
• Calculation of median reverse fragility index for RCTs with statistically nonsignificant outcomes.

Main Results:

• The median fragility index for significant RCTs was 5.5 (95% CI 1-30).
• The median reverse fragility index for nonsignificant RCTs was 13 (p=0.05) and 16 (p=0.01).
• The included RCTs were generally of good quality, with a median Jadad score of 6.

Conclusions:

• The 2016 SSC guidelines are supported by highly robust RCTs, particularly those with statistically nonsignificant results.
• RCTs with nonsignificant findings demonstrated greater robustness compared to those with significant findings.
• The evidence base for sepsis management guidelines is strong, with nonsignificant results indicating more resilient findings.
