We prospectively compared the new Japanese Association for Acute Medicine (JAAM) score with the International Society of Thrombosis and Hemostasis (ISTH) score for diagnosis of disseminated intravascular coagulation (DIC) in septic patients admitted in a general critical care intensive care unit.


Septic patients with platelet count of <150 × 10(9)/L were included. Both DIC scores were estimated from day 1 to day 4 along with APACHE II and SOFA scores.


Out of the 148 blood samples drawn from 42 patients (28 male & 14 female) the JAAM and ISTH DIC scores had an overall significant agreement (k=0.246, p<0.001) in 83 samples. JAAM score had higher diagnostic rates on all four days. Significant (p ≤ 0.001) day wise variation existed in JAAM and ISTH DIC scores. Correlation between JAAM DIC and ISTH DIC scores on day 1 (r=0.631) & day 4 (r=0.609) was significant (p<0.001). Pneumonia was the predominant cause of sepsis. Twenty seven (64.3%) patients died during their stay in ICU. Amongst DIC patients both severity scores (SOFA/APACHE II) and DIC scores (JAAM/ISTH) did not discriminate between survivors and non-survivors. Health care associated infection (p=0.040), high lactate levels (p=0.020) on day 1 and high procalcitonin levels (p=0.036) were found to have significant discriminating ability between survivors and non-survivors. Significantly shorter length of stay was observed amongst non-survivors (p=0.002).


In sepsis the JAAM DIC score identified most of the patients diagnosed by the overt ISTH criteria, but failed to discriminate between survivors and non-survivors amongst DIC patients.
