Recent studies have suggested improved outcomes in victims of penetrating trauma managed with shorter prehospital times and limited interventions. The purpose of the current study was to perform an outcome analysis of patients transported following penetrating and blunt traumatic injuries.We performed a descriptive retrospective analysis of the 2014 National Emergency Medical Services Information System (NEMSIS) public release research data set for patients presenting after acute traumatic injury.A total of 2,018,141 patient encounters met criteria, of which 3.9% were penetrating trauma. Prehospital cardiac arrest occurred in 0.5% blunt and 4.2% penetrating trauma patients. Emergency department (ED) mortality was higher in penetrating than blunt trauma patients (4.1% vs. 0.8%). Scene times were 18.1 ± 36.5 minutes for blunt and 16.0 ± 45.3 minutes for penetrating trauma. Mean scene time for blunt trauma patients who died in the ED was 24.9 ± 58.0 minutes compared with 18.8 ± 38.5 minutes for those admitted; for penetrating trauma, scene times were 17.9 ± 23.5 and 13.4 ± 11.6 minutes, respectively. Mean number of procedures performed for blunt trauma patients who died in the ED was 6.5 ± 4.3 compared with 3.1 ± 2.3 for those who survived until admission; for penetrating trauma, the numbers of procedures performed were 5.7 ± 3.4 and 2.6 ± 2.0, respectively.Although less frequent than blunt trauma, penetrating trauma is associated with significantly higher prehospital and ED mortality. Increased scene time and number of procedures was associated with greater mortality for both blunt and penetrating trauma. Further study is required to better understand any causal relationships between prehospital times and interventions and patient outcomes.
