Background: Alongside its original diagnostic intention, the International Society on Thrombosis and Haemostasis' (ISTH) disseminated intravascular coagulation (DIC) score predicts mortality in various patient groups.
Objectives: We investigated whether coagulopathy quantified by the DIC score can predict 30-day mortality in patients with liver disease and low fibrinogen levels.
Methods: We retrospectively analyzed all patients admitted to the Vienna General Hospital between 2003 and 2014 with a fibrinogen level of <150 mg/dL, a history of liver disease, and ≥2 pathological DIC parameters. We used a Cox regression and receiver operating characteristic analysis to assess the predictive value of the ISTH DIC score in its original (DIC-2001) and revised form (DIC-2018).
Results: A total of 1,333 patients were screened, and 388 of these patients (38% female, median age: 58 years, interquartile range: 48-66 years) were analyzed. The DIC-2001 (hazard ratio [HR]: 2.08, 95% confidence interval [CI]: 1.78-2.59, p < 0.001) and DIC-2018 (HR: 1.73, 95% CI: 1.51-2.05, p < 0.001) predicted 30-day mortality. The results remained robust in several sensitivity analyses.
Conclusion: The ISTH DIC-2001 and DIC-2018 scores predicted 30-day mortality in patients with liver disease and low fibrinogen levels. The DIC score deserves further investigation in this population as it likely reflects different dimensions of the underlying disease.
