ObjectivesTo evaluate the utility of dielectric blood coagulometry for early sepsis-induced disseminated intravascular coagulation diagnosis.DesignSingle-center, prospective observational study.SettingPatients with sepsis or septic shock at the Tokyo Medical and Dental University Hospital of Medicine between September 2019 and September 2020.PatientsThe patients were divided into three groups according to the timing of disseminated intravascular coagulation diagnosis based on the Disseminated Intravascular Coagulation score by the Japanese Association for Acute Medicine: 1) no disseminated intravascular coagulation group, 2) late-diagnosed disseminated intravascular coagulation group: not diagnosed with disseminated intravascular coagulation on day 1 but diagnosed within 48 hours after admission, and 3) disseminated intravascular coagulation group: diagnosed with disseminated intravascular coagulation on day 1. The study evaluated 80 patients (no disseminated intravascular coagulation, 31 [38.8%]; late-diagnosed disseminated intravascular coagulation, 34 (42.5%); disseminated intravascular coagulation, 15 [18.8%]).Measurements And Main ResultsWe compared the clinical severity scores and mortality of the groups and assessed the correlation between the dielectric blood coagulometry-derived coagulation marker, thrombin levels, and Disseminated Intravascular Coagulation score using Spearman rank correlation. The mortality rate was 0% (0/31) in the no disseminated intravascular coagulation group, 35.3% (12/34) in the late-diagnosed disseminated intravascular coagulation group, and 33.3% (5/15) in the disseminated intravascular coagulation group. Although the Disseminated Intravascular Coagulation score on day 1 did not reflect disseminated intravascular coagulation in approximately 70% of patients who developed disseminated intravascular coagulation by day 2, dielectric clot strength measured by dielectric blood coagulometry on day 1 strongly correlated with disseminated intravascular coagulation development by day 2 (Spearman ρ = 0.824; p < 0.05) and with thrombin level on day 1 (Spearman ρ = 0.844; p < 0.05).ConclusionsDielectric blood coagulometry can be used to detect early-phase disseminated intravascular coagulation in patients with sepsis and is strongly correlated with thrombin levels. Larger studies are needed to verify our results for developing clinical applications.Copyright © 2021 The Author(s).
