An ancillary analysis to the SepsiCoag multicentric prospective observational study on patients entering an intensive care unit with septic shock evaluated the prognostic potential of fibrin generation markers (FGMs) tested at inclusion in the study, on survival at day 30. After centralization of samples, three automated FGMs were compared: D-dimers (DDi), fibrin/fibrinogen degradation products (FDP) and fibrin monomers (FM). FM was the single FGM that was significantly higher in non-surviving patients, area under the receiver-operator characteristic curve (AUCROC ): 0·617, P < 0·0001. Significantly higher International Society on Thrombosis and Haemostasis Disseminated Intravascular Coagulation (ISTH DIC) scores were calculated in non-survivors using each of the three FGMs. A dose-effect relationship was observed between ISTH DIC scores and non-survival, with highest significance obtained using FM as the FGM. An overt DIC diagnosis using the ISTH DIC score calculated using FM was a predictor of non-survival at day 30, independently from overt DIC diagnosis based on scores calculated using FDP or DDi. The AUCROC values testing the ability of the ISTH DIC score to predict non-survival were 0·650, 0·624 and 0·602 using FM, DDi and FDP, respectively, as the FGM. In patients with septic shock, among the commercially-available automated assays, automated FM is the FGM best related with late prognosis.
