Death rates provide an incomplete picture of the effect of firearm injuries. To devise appropriate prevention efforts, investigations of the severity and prognosis of both fatal and nonfatal gunshot wounds (GSW) are pivotal, yet they remain scarce. We studied temporal patterns of GSW-associated severity and mortality in a Colorado urban trauma center and of all trauma deaths occurring in its catchment area from 2000 to 2013. From 2000 to 2013, 28 948 patients presented to the DHMC with injuries due to GSWs (5.8%), stabbings (6.3%), pedestrian accidents (6.9%), assaults (8.7%), falls (23.9%), motor vehicle crashes (26.2%), and other mechanisms (22.1%). Of these, 5.4% died. The proportions of DHMC injury admissions due to GSWs, stabbings, and assaults remained stable from 2000 to 2013, whereas falls increased (from 16.8% to 27.8%) and motor vehicle crashes decreased (from 37.0% to 19.7%) over time. Adjusted in-hospital case-fatality rates for GSWs at the DHMC significantly increased (RR per biennium, 1.06 [95% CI, 1.03-1.08]; RD, 0.51% [95% CI, 0.01%-1.02%]) and the TRISS-derived survival probabilities decreased (P = .002). All other mechanisms presented stable or opposite temporal trends for deaths and survival probability. Over time, more GSW patients had an ISS higher than 25 (RR per biennium, 1.06 [95% CI, 1.04-1.08]; RD, 1.16% [95% CI, 0.68%-1.65%]). In addition, the number of severe GSWs per patient increased significantly (RR per biennium of >2 severe injuries, 1.04 [95% CI, 1.02-1.06]; RD, 1.22% [95% CI, 0.66%-1.79%]). Firearm in-hospital case-fatality rates increased, contrary to every other trauma mechanism, attributable to the rising severity and number of injuries. The differential in severity and mortality is unlikely due to improved emergency medical services (ie, more severely injured patients arriving alive to the hospital vs dying in the field), as there were no changes in deaths at the scene over time. This single trauma center study has limited generalizability. A renewed attention to research and policy are needed to decrease the morbidity and mortality of GSWs. © 2016 American Medical Association. All Rights Reserved.
