Scoring system for overt disseminated intravascular coagulation proposed by International Society on Thrombosis and Haemostasis
| Score | |
|---|---|
| Platelet counts | |
| <50 × 109/l | 2 |
| ≥50 <100 × 109/l | 1 |
| ≥100 × 109/l | 0 |
| Elevated fibrin-related markera | |
| Strong increase | 3 |
| Moderate increase | 2 |
| No increase | 0 |
| Prolonged prothrombin time | |
| ≥6 seconds | 2 |
| ≥3 <6 seconds | 1 |
| <3 seconds | 0 |
| Fibrinogen level | |
| <100 g/ml | 1 |
| ≥100 g/ml | 0 |
| Calculate score | |
| If >5, compatible with overt DIC; repeat scoring daily | |
| If <5, suggestive (not affirmative) for nonovert DIC; repeat next 1 to 2 days. |
DIC, disseminated intravascular coagulation. aFor example, soluble fibrin monomers/fibrin degradation products.
