The prevalence of sepsis-induced coagulopathy in patients with sepsis – a secondary analysis of two German multicenter randomized controlled trials

Abstract Background Sepsis and septic shock are frequently accompanied by coagulopathy. Since the sepsis-induced coagulopathy (SIC) score was first described, subsequent studies from Asia revealed a SIC prevalence of 40–60%. In Europe, however, SIC prevalence in patients fulfilling sepsis criteria according to the third international consensus definition (SEPSIS-3) has not yet been evaluated. Methods The Critical Care Trials Group of the German Sepsis Competence Network (SepNet) conducted a secondary analysis of two randomized controlled trials. Only patients fulfilling sepsis criteria according SEPSIS-3 were included in this secondary analysis. In a two step approach, SIC prevalence was determined in 267 patients with sepsis but not septic shock (at the time of inclusion) from the “Effect of Hydrocortisone on Development of Shock Among Patients With Severe Sepsis” (HYPRESS) trial. Then, we estimated SIC prevalence in 1,018 patients from the “Effect of Sodium Selenite Administration and Procalcitonin-Guided Therapy on Mortality in Patients With Severe Sepsis or Septic Shock” (SISPCT) trial using a simplified SIC score based on the platelet-SIC-subscore (PSSC). Study aims were to assess (i) the prevalence of SIC in patients with SEPSIS-3, (ii) the association of SIC with 90-day mortality and morbidity, (iii) the time when patients become SIC positive during the course of sepsis, and (iv) the value of the PSSC for predicting SIC. Results In the HYPRESS trial, SIC prevalence was 22.1% (95% confidence interval [CI] 17.5–27.5%). The estimated SIC prevalence in the SISPCT trial was 24.2% (95% CI 21.6–26.9%). In the HYPRESS trial, SIC was associated with significantly higher 90-day mortality (13.9% vs. 26.8%, p = 0.027) and morbidity. Logistic regression analysis adjusted for age, sex, treatment arm, and (SIC-adapted) SOFA score confirmed the negative association of SIC with survival (p = 0.011). In the SISPCT trial, increased PSSCs were associated with higher 90-day mortality (PSSC 0: 34.4%, PSSC 1: 40.5%, PSSC 2: 53.3%; p
