Disseminated Intravascular Coagulation Score Predicts Mortality in Patients with Liver Disease and Low Fibrinogen Level.

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.
