Diagnoses overt disseminated intravascular coagulation (DIC) using ISTH scoring system. Score >=5 indicates overt DIC requiring urgent management.

Score interpretation

→ Repeat in 24-48h if clinical suspicion high; treat underlying cause; monitor coagulation trend; no specific DIC therapy required unless active bleeding

Overt DIC (score >=5)

→ Treat underlying cause urgently (sepsis, malignancy, obstetric complication, trauma); FFP 15ml/kg if bleeding or invasive procedure planned; cryoprecipitate if fibrinogen <1.5 g/L; platelet transfusion if <20-50 + bleeding; haematology consult; daily monitoring
