Abstract

Background: Thromboelastometry/elastography (ROTEM/TEG) showed promising results for diagnosis of sepsis-induced coagulopathy, but their association with the outcome is unclear. Our aim was to assess any difference in ROTEM/TEG measurements between septic survivors and non-survivors.

Methods: Pubmed, Web of Science, Embase and Cochrane Library databases were investigated. The research aimed to include any randomized or observational study: i) on septic adult patients admitted to Intensive Care Unit (ICU) or Emergency Department (ED); ii) including ROTEM/TEG; iii) assessing mortality.

Results: Seven prospective and four retrospective observational studies (952 patients) were included. According to the INTEM/kaolin-assay, clotting time (CT)/R (standardized mean difference(SMD) -0.29, 95% CI -0.49 to -0.09, p = 0.004) and clot formation time (CFT)/K (SMD -0.42, 95% CI -0.78 to -0.06, p = 0.02) were shorter in survivors. According to the EXTEM-assay, CT was shorter (MD -11.66 s, 95% CI -22.59 to -0.73, p = 0.04), while MCF was higher (MD 3.49 mm, 95% CI 0.43 to 6.55, p = 0.03) in survivors. A hypocoagulable profile was more frequent in non-survivors (OR 0.31, 95%CI 0.18 to 0.55, p < 0.0001). Overall, the risk of bias of the included studies was moderate and the quality of evidence low.

Conclusions: Hypocoagulability and lower MCF in EXTEM may be associated with higher mortality in sepsis.
