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.
