In civilian practice, the incidence of firearm violence depends on the country. In high income countries, most cases are reported in the USA or South Africa. In these countries, gunshot wounds (GSW) represent 20% of death cases in trauma centers, more than motor vehicle collisions.

The mortality in civilian practice occurs during the first 24 hours following GSW, mainly due to hemorrhage and traumatic brain injury, though long term effects on physical and psychological outcomes have also been shown.

Some factors of mortality specific to GSW have been established: multiples wounds, homicide vs suicide attempt, impact zone, or firearm caliber.

Few specific guidelines have been published concerning civilian GSW management. These cases are mostly treated in standard guidelines, such as hemorrhagic shock or traumatic brain injury guidelines. As in other trauma mechanisms, the "platinum ten minutes and golden hour" concept is applicable.

In Europe, the incidence of civilian GSW is much lower and few European studies have been published recently. Penetrating injuries in Europe are less likely to be GSW, and are more often self-inflicted than in the USA. In addition, European studies are heterogeneous, due to the difference in populations, healthcare systems and GSW being grouped with stabbing wounds under the label "penetrating trauma".

However, there is a global concern in Europe regarding a potential rise of GSW, with higher severity score than conventional trauma patients and often necessitate ICU admission. Studies analyzing data from different European countries show significantly different ICU admission rates for overall GSW, ranging from 17% up to 30%.

Therefore, the investigators conducted a multicenter, retrospective study on four French University Hospitals aiming to describe the epidemiology (mortality and type of organ damage) and identify prognosis factors of civilian GSW admitted in ICU.
