Principal component analysis of coagulation assays in severely injured children

Principal component analysis detects 3 patterns of coagulation dysregulation using widely available laboratory parameters: (1) abnormalities in clot strength; (2) abnormalities in fibrinolysis, and (3) clotting factor depletion. While all were associated with mortality and transfusion, fibrinolytic dysregulation was associated with injury severity and portends particularly poor outcome including venous thromboembolism and disability.
