Predicting mortality in patients with disseminated intravascular coagulation after cardiopulmonary bypass surgery by utilizing two scoring systems

We evaluated clinical and laboratory biomarkers of disseminated intravascular coagulation (DIC) following cardiac surgery in the cardiothoracic surgical ICU (CTICU) to predict mortality. We retrospectively analyzed CTICU patients with suspected DIC identified from the hospital laboratory database, and calculated International Society on Thrombosis and Haemostasis (ISTH) and the Japanese Association for Acute Medicine (JAAM) DIC scores to predict DIC-related mortality. The predictive accuracy of the JAAM and ISTH DIC scoring system were then assessed by logistic regression analysis and receiver operative characteristics analysis, and compared to other potential predictors of mortality (e.g., Acute Physiology and Chronic Health Evaluation II, systemic inflammatory response syndrome criteria, laboratory variables). Our study showed a 30-day mortality rate of 71% in CTICU patients with DIC. The JAAM DIC score offered the best predictive accuracy [area under the curve (AUC): 0.723, 95% % confidence interval (CI): 0.638–0.947, P = 0.021], when compared with ISTH DIC score (AUC: 0.707, 95% CI: 0.491–0.923, P = 0.066) and Acute Physiology and Chronic Health Evaluation II (AUC: 0.687, 95% CI: 0.483–0.891, P = 0.110). A JAAM DIC score at least 6 was reported in 89% of the nonsurvivors and 46% of survivors (P = 0.010), and predicted mortality [odds ratio: 9.33 (1.50–58.20)] with a 73% sensitivity and a 78% specificity. Our results also show a strong relationship ...
