If you make it to a hospital alive, you have about a 67% chance of surviving a gunshot wound, and an 92% chance of surviving a stab wound.
"The study, published online ahead of print in the Annals of Emergency Medicine, examined 4,122 patients taken to eight Level I and Level II adult trauma centers in Philadelphia between January 1, 2003 and December 31, 2007. Of these, 2,961 were transported by EMS and 1,161 by the police. The overall mortality rate was 27.4 percent. Just over three quarters (77.9 percent) of the victims suffered gunshot wounds, and just under a quarter (22.1 percent) suffered stab wounds. The majority of patients in both groups (84.1 percent) had signs of life on delivery to the hospital. A third of patients with gunshot wounds (33.0 percent) died compared with 7.7 percent of patients with stab wounds.
Although patients transported by the police department were more likely to die compared with those transported by EMS (29.8 percent versus 26.5 percent), these findings appear to be explained by the more severely injured population that the police typically transport to the hospital and not the mode of transport itself."
