Abstract :
[en] Introduction: Identifying patients who need damage control resuscitation (DCR) early after trauma is pivotal for
adequate management of their critical condition. Several trauma-scoring systems have been developed to
identify such patients, but most of them are not simple enough to be used in prehospital settings in the early
post-traumatic phase. The Trauma Induced Coagulopathy Clinical Score (TICCS) is an easy-to-measure and strictly
clinical trauma score developed to meet this medical need.
Methods: TICCS is a 3-item clinical score (range: 0 to 18) based on the assessment of general severity, blood
pressure and extent of body injury and calculated by paramedics on-site for patients with severe trauma. This
non-interventional prospective study was designed to assess the ability of TICCS to discern patients who need
DCR. These patients were patients with early acute coagulopathy of trauma (EACT), haemorrhagic shock, massive
transfusion and surgical or endovascular haemostasis during hospitalization. Diagnosis of EACT was assessed by
both thromboelastometry and conventional coagulation tests.
Results: During an 18-month period, 89 severe trauma patients admitted to the general emergency unit at our
hospital were enrolled in the study, but 7 were excluded for protocol violations. Of the 82 remaining patients, 8
needed DCR and 74 did not. With receiver operating characteristic curve analysis, TICCS proved to be a powerful
discriminant test (area under the curve = 0.98; 95% CI: 0.92 to 1.0). A cutoff of 10 on the TICCS scale provided the
best balance between sensitivity (100%; 95% CI: 53.9 to 100) and specificity (95.9%; 95% CI: 88.2 to 99.2). The positive
predictive value was 72.7%, and the negative predictive value was 100.0%.
Conclusion: TICCS can be easily and rapidly measured by paramedics at the trauma site. In this study of blunt
trauma patients, TICCS was able to discriminate between patients with and without need for DCR. TICCS on-site
evaluation should allow initiation of optimal care immediately upon hospital admission of patients with severe
trauma in need of DCR. However, a larger multicentre prospective study is needed for in-depth validation of TICCS.
