Comparative StudyEvaluation of the International Society on Thrombosis and Haemostasis and institutional diagnostic criteria of disseminated intravascular coagulation in pediatric patients.
Globally, adult intensive care units routinely use the International Society on Thrombosis and Haemostasis (ISTH) scoring system for identifying overt disseminated intravascular coagulation (DIC). However, in our pediatric intensive care unit, a modified diagnostic criterion (Texas Children's Hospital [TCH] criteria) that requires serial monitoring of the coagulation variables is employed. A retrospective analysis of 2,136 DIC panels from 130 patients who had at least 4 DIC panels during 1 admission to a pediatric intensive care unit was done to compare the diagnostic utility of the TCH criteria with the ISTH scoring method in children. ⋯ On the contrary, TCH diagnostic criteria perform better, with a sensitivity significantly higher than the ISTH scoring method when tested against the gold standard (P < .05). Fibrinogen is not a significant predictor of overt DIC in both models. Sequential testing of coagulation parameters is recommended for improved sensitivity when applying ISTH criteria to pediatric populations.
