Abbreviation: GSW, gunshot wound.
Includes 252 with GSWs and 112 with only nonballistic trauma (fall, stampede, trampling, blunt, or external). Injury Severity Scores (ISS) are calculated as the sum of squares of the 3 most injured Abbreviated Injury Score body regions. Major trauma (or multiple trauma) is defined as ISS greater than 15. A total of 153 patients with ISS available had major trauma, including 24 of 97 (24.7%) with GSWs and 1 of 56 (1.8%) with non-GSW injuries. Median ISS for all GSW injuries was 4 (IQR, 1-9 [range, 1-48]); for all non-GSW injuries, 1 (IQR, 1-4 [range, 0-19]).
Fifty-eight of 81 patients with GSWs and any fracture (71.6%) had open fractures. There were no recorded open fractures in patients with non-GSW injuries. Given that open fracture is a subtype of total fractures, these were counted only once in the calculation of total musculoskeletal trauma.
Includes 13 intracranial (epidural, subdural, subarachnoid, intraparenchymal, and cerebral hemorrhage/laceration) injuries by GSWs.
