To evaluate whole-body-CT-scan efficiency in the assessment of polytrauma victims during emergency conditions.

Retrospective study of 350 polytrauma victims admitted from January 2002 to March 2004 at the level 1 Trauma Center European Hospital Georges Pompidou in Paris.We compared the whole-body-CT-scan results with surgical findings (32% of the patients were operated) and the clinical follow up.False positives (FP), false negatives (FN), positive predictive value (PPV), negative predictive value (NPV) were determined and calculated for the different anatomic regions explored (head/ spine/ thorax/ abdomen/ other).Injury Severity Score (ISS) was also calculated and correlated with mortality.

Accuracy of whole-body-CT-scan was very high (>90%) with only 6% of false positives which did not interfere with patient survival.FN (9%) were mainly intestinal and vascular lesions.PPV was 94% and NPV was 91%.An ISS superior to 16 was correlated with a high mortality rate.

Whole-body-CT-scan has a high accuracy in evaluating polytrauma victims. It is therefore the most appropriate method of evaluation.
