Prospective evaluation of three different diagnostic criteria for disseminated intravascular coagulation

Abstract

SummaryThere are three different diagnostic score systems for disseminated intravascular coagulation (DIC) established by the Japanese Ministry Health and Welfare (JMHW), the International Society on Thrombosis and Haemostasis (ISTH) and the Japanese Association for Acute Medicine (JAAM). The JMHW criteria are still used in Japan. In the present study, all three diagnostic criteria were used to prospectively evaluate 413 patients with different underlying diseases of DIC who were treated at the Mie University Hospital (JMHW, n= 166; ISTH, n=143; JAAM, n=291). The odds ratio (95% confidence interval) for death was 1.88 (1.22 – 2.90) in JMHW, 2.55 (1.65 – 3.95) in ISHT and 1.99 (1.19 – 3.32) in JAAM. The platelet count, prothrombin time, fibrin and fibri-nogen degradation products and fibrinogen were significantly important for diagnosis of DIC by all three diagnostic criteria. Haemostatic molecular markers were significantly high in all patients and were useful for the diagnosis of DIC. The JAAM diagnostic criteria displayed a high sensitivity for DIC and the ISTH overt-DIC diagnostic criteria displayed a high specificity for DIC. All three diagnostic criteria for DIC were related to a poor patient outcome.
