Introduction:
In a Nordic context, there are few epidemiological studies on trauma patients hospitalised due to interpersonal violence. The purpose of this study was to identify the characteristics and outcomes of this patient group.
Methods:
We performed a retrospective analysis of the trauma registry at Stavanger University Hospital from 2004 through 2021. Patient demographics, assault mechanism, alcohol involvement, injury severity score (ISS), location of major injury (LOMI), clinical outcome and mortality were compared.
Results:
499 patients were identified with a median age of 30 (SD 12.8, 7-79 years). 65% of the patients were in the age group 20-40 years. 86% were men (N = 429) and the male predominance was statistically significant in all age groups (p-value < 0.002). Ethanol was detected in the majority of the patients (61.3%) with a median concentration of 2.04 (SD 0.822, 0.1-4.5).
Most patients presented with blunt injuries (68.3%) with no statistically significant differences in age or gender. Median ISS was 6 (SD 8.2, 1-75) with 55.5% (N = 276) presenting with minor, 29% (N = 144) with moderate, 10.7% (N = 53) with severe injury and 4.8% (N = 24) with very severe injury. Injury severity did not significantly differ in blunt and penetrating injuries.
Overall 30-day mortality rate was 2.6% (N=13) with most of these patients presenting with ISS > 24 (p-value < 0.001). No statistically significant difference in mortality was found between the age groups, but there were more fatalities in the female compared to the male population (p-value 0.002).
Conclusion:
Trauma patients admitted due to interpersonal violence are primarily young, male and under the influence of alcohol. The majority present with minor injuries (ISS < 8) due to blunt trauma, while mortality rates are higher in those with ISS-score > 24 and in women.
