Abstract

Objectives:

Disseminated intravascular coagulation is a complex systemic thrombohemorrahgic disorder, which may contribute to organ failure. We aimed to compare the detection rate of the disseminated intravascular coagulation, early in the course of ICU admission, of the two disseminated intravascular coagulation scoring systems defined by International Society on Thrombosis and Hemostasis and Japanese Association for Acute Medicine criteria and the prognostic value of disseminated intravascular coagulation scores in critically ill pediatric patients.

Design:

Single-center retrospective observational study.

Setting:

PICU in a tertiary care children’s hospital.

Patients:

Pediatric patients admitted in the PICU between January 2013 and December 2014.

Interventions:

None.

Measurements and Main Results:

A total of 191 patients were included. Among them, 15.7% and 29.8% of the patients were diagnosed with disseminated intravascular coagulation by International Society on Thrombosis and Hemostasis and Japanese Association for Acute Medicine criteria, respectively. The diagnostic concordance rate between the International Society on Thrombosis and Hemostasis and Japanese Association for Acute Medicine scoring systems was 52.6%. As the Pediatric Risk of Mortality III, the modified Sequential Organ Failure Assessment, and the Pediatric Multiple Organ Dysfunction Syndrome scores increased, the percentage of patients with disseminated intravascular coagulation increased stepwise. The disseminated intravascular coagulation scores correlated well with these severity scores. Overall, the 28-day mortality was 9.9%. There were significant differences in most variables consisting of the International Society on Thrombosis and Hemostasis and Japanese Association for Acute Medicine scoring systems between survivor and nonsurvivors. Patients detected to have disseminated intravascular coagulation by the International Society on Thrombosis and Hemostasis and Japanese Association for Acute Medicine scoring systems showed higher mortality than patients without disseminated intravascular coagulation. The areas under the receiver operating characteristic curve of the Japanese Association for Acute Medicine score and International Society on Thrombosis and Hemostasis score were 0.788 (95% CI, 0.675–0.900) and 0.716 (95% CI, 0.598–0.834), respectively.

Conclusions:

Both the International Society on Thrombosis and Hemostasis and the Japanese Association for Acute Medicine scoring systems are useful for detection of the disseminated intravascular coagulation in critically ill pediatric patients. These scores correlate well with other severity scores, including Pediatric Risk of Mortality III, modified Sequential Organ Failure Assessment, and Pediatric Multiple Organ Dysfunction Syndrome. Disseminated intravascular coagulation scores are also significantly associated with 28-day mortality, suggesting that these could be promising prognostic factors.
