Gunshot injuries in Central Europe - Epidemiology and outcome in Germany, Switzerland and Austria - an analysis based on the TraumaRegister DGU®.

Background: Firearms are of special interest in trauma research due to high lethality and criminal value. Strong correlation between guns per capita and fire-arm related deaths has been shown. Most of existing literature regarding gun-shot fatalities are from the U.S. and data for Central Europe is lacking. Thus, the aim of this study was to assess the legal frameworks regarding gun-ownership in Germany (DE), Austria (A) and Switzerland (CH), and to retrospectively analyze data from the TraumaRegister DGU® regarding the epidemiology, injury severity, intention and outcome of gunshot-related deaths in these countries.
Methods: All patients from TR-DGU who sustained a gunshot injury in the time period from 1st January 2009 to 31st December 2019 were considered for analysis. Only cases admitted to level 1 or 2 trauma center in Germany, Switzerland, or Austria were included. Predicted mortality was calculated using the RISC-II. Further, the legal framework for firearm posession were explored.
Results: The legal frameworks do not differ significantly between the countries. However, only ex-military men from Switzerland are allowed to keep their automatic (military) weapon at home. We assessed 1312 gunshot fatalities (DE 1,099, A 111, CH 102) of which most were due to suspected suicide (A 72.1 %, CH 64.7 %, and DE 56.6 %, p = 0.003). Act of suspected violent crime or accidental gunshots were rare in all three countries. Amongst all gunshot fatalities, Austria showed the highest mean age (57.6 years), followed by DE (53.4 years) and CH (49.4 years; p < 0.01). Gunshot fatalities amongst all assessed countries due to suspected suicide showed a peak at the age of 60 years and above, whereas suspected violent crime delicts with gunshots were mainly seen in younger age groups. The highest mortality was found in suspected suicide cases, showing a mortality of 82.1 % (predicted 65.2 %) in Switzerland, 75.3 % (predicted 65.8 %) in Austria and 63.7 % (predicted 56.2 %) in Germany.
Conclusion: Gunshot wounds are still rare in central Europe, but gunshot-related suicide rates are high. Gun ownership laws may have an impact on gunshot wounds due to suspected suicide. Injury patterns differ compared to countries where a high incidence of gun ownership is seen.
