Validation of sepsis-induced coagulopathy score in critically ill patients with septic shock: post hoc analysis of a nationwide multicenter observational study in Japan.
2021
Coagulation disorder is a major cause of death in sepsis patients. Recently, sepsis-induced coagulopathy (SIC) scoring was developed as a new criterion for coagulopathy-associated sepsis. We aimed to evaluate the accuracy of the SIC score for predicting the prognosis of septic shock. We analyzed data from a multicenter observational study conducted from 2011 to 2013. We grouped the participants into those who did and did not use vasopressors, and compared the in-hospital mortality rates of SIC and non-SIC patients. Patients who needed vasopressors were considered to have septic shock. We performed survival analysis adjusted by factors independently associated with mortality. SIC developed in 66.4% of patients who used vasopressors and 42.2% of patients who did not. The in-hospital mortality difference between the SIC and non-SIC groups was statistically significant in those who needed vasopressors (35.8% vs 27.9%, p < 0.01). Cox regression analysis indicated that SIC was significantly correlated with mortality risk in patients who used vasopressors (hazard ratio [HR] 1.39; 95% confidence interval [CI] 1.13–1.70; p < 0.01), but not in those who did not (HR 1.38; 95% CI 0.81–2.34; p = 0.23). In conclusion, the SIC score might be a good diagnostic indicator of fatal coagulopathy among sepsis patients who need vasopressors.
