Score interpretation – DIC is diagnosed if total score is ≥4

SIRS: systemic inflammatory response syndrome; PT: prothrombin time; INR: international normalized ratio; DIC: disseminated intravascular coagulation.
* SIRS criteria include abnormal (high or low) core temperature, tachycardia, tachypnea, and abnormal (high or low) leukocyte count. For details of SIRS criteria, refer to UpToDate topic reviews on sepsis and SIRS in adult and pediatric patients.
