The paper, published Thursday in JAMA Surgery, analyzed more than 1 million patient files for both firearm injuries and motor vehicle crashes between 2003 and 2013. Researchers looked at the severity of injuries, as well as in- and out-of-hospital deaths, for both incidents. They found that, while there was 0.17% decline in the number of car accident deaths, the number of gunshot victims who died stayed more or less the same.
Although there are a number of factors that can contribute to a person's survival rate after a crash or gunshot, including location of the injury and depth of wounds, researchers concluded that the stagnant survival rate of gunshot victims could be attributed to "a worsening of firearm injury severity over time."
The study doesn't examine why there hasn't been a decline in firearm-related deaths. It does, however, offer a possible solution (Or at the very least, a step in that direction). According to the researchers, incorporating studies of firearm ballistics into longitudinal public health and trauma surgery research will give medical professionals more insight into firearm lethality.
Additionally, adding details on "firearm type, ammunition used, shots fired, and number of wounds can provide a more complete picture of firearm injury severity over time," which can help doctors better protect patients in the future.
