DIC score

German: DIC-score

1 Definition

The DIC score is a scoring system that is based on laboratory parameters. It is used to estimate the possibility of a disseminated intravascular coagulation (DIC) being present. For the diagnosis of a DIC clinical criteria as well as laboratory parameters have to be taken into account. The score is only allowed to be applied when an underlying disease, that can typically cause disseminated intravascular coagulation, is present.

2 Calculation

platelet count >1009/l 1009/l - 509/l <509/l
marker for fibrin formation
(i.e. D-dimers)
not elevated moderatly elevated heavily elevated
prolonged prothrombin time <3 s 3 s - 6 s >6 s
fibrinogen level - >1 g/l <1 g/l
Points 0 1 2

A complication present in Germany ist that the prothrombin time is normally reported in form of Quick’s value (in %). In this case one has to inquire the laboratory for the raw values or use an orientating conversion. Also the assessment of the fibrin markers is not clearly defined and has to be clarified by consulting the hemostaseologic laboratory.

A score of 5 points or larger points to a florid DIC. The calculation should be repeated on a daily basis in order to cover the dynamic situation of a DIC.
