About

The whole-body scanner (SCE) is a powerful examination that guides the management of patients severely traumatized. However, the systematic use of this examination in emergency departments is responsible for a large proportion of normal examinations. In addition to the non-negligible direct cost, the average irradiation of 20 mSv would give an adult a 1 in 1000 risk of developing a cancer. The Vittel score makes it possible to categorize pre-hospital patients as seriously traumatized to guide the sending of resources and direct them to a center equipped with a suitable technical platform.

The use of this score to condition the prescription of the ECS is at the origin of an over-triage important since one out of two patients who validates at least one criterion has no lesion on imaging. The purpose of this research project is to validate a decision support tool to objectively guide the emergency physician in its use of the ECS. At the same time, the economic impact of such a procedure will be analysed.
