ABSTRACT
PURPOSE: Trauma mechanisms and patterns of severe injuries during the Estonian independence have not been evaluated. The aim of the study was to compare the incidence and outcomes of severe injuries between time periods of early independence from the Soviet Union and the present time. METHODS: After the ethics review board approval, all adult trauma admissions to major trauma facilities in 1993-1994 and 2013-2014 with Injury Severity Score >15 were identified. Data collection included demographics, injury severity variables, interventions, and in-hospital outcomes. Primary outcome was in-hospital mortality. Secondary outcomes included incidence of penetrating trauma, hospital length of stay (HLOS), and in-hospital complications. Primary outcome difference comparing the two time segments was determined using logistic regression analysis. RESULTS: A total of 1064 patients were included, 593 and 471 from 1993-1994 to 2013-2014, respectively. Incidence of penetrating trauma during 1993-1994 was 11.1 % and in 2013-2014 at 6.4 % (p = 0.007). Gunshot injuries constituted 62.1 and 23.3 % of all penetrating trauma in 1993-1994 and 2013-2014, respectively (p < 0.001). The overall mean HLOS was 15.5 ± 19.8 days and did not differ between the periods. The rate of adjusted complications showed a trend for a decreased incidence (adj. p = 0.064). Adjusted mortality rate was 50.3 and 16.4 % during 1993-1994 and 2013-2014, respectively (adj. OR 7.01; 95 % CI 4.69-10.47; p < 0.001). CONCLUSIONS: Effective law enforcement, gun control, evolution of trauma system, and reduction of interpersonal violence have all contributed to a significant decrease in penetrating trauma incidence and all-cause adjusted mortality during the 20 years of Estonian independence.

PURPOSE: The purpose of this study was to investigate epidemiology of severe injuries in Estonia while comparing outcomes at regional trauma facilities. METHODS: After the ethics review board approval, all consecutive trauma admissions with Injury Severity Score (ISS) > 15 to North Estonia Medical Center/Tallinn Children's Hospital (NEMC + TCH) and Tartu University Hospital (TUH) were identified between 1/1/2013 and 31/12/2013. Data collection included demographics, admission data, injury severity variables, interventions, and in-hospital outcomes. Primary outcome was in-hospital mortality. Secondary outcomes were complications per Clavien-Dindo and hospital length of stay (HLOS). Logistic regression analysis was used to compare adjusted mortality between the two regional hospitals. RESULTS: A total of 256 patients met inclusion criteria. The mean ISS for the cohort was 23.6 ± 7.8, 13.3 % were hypotensive on admission, and 44.1 % had a Glasgow Coma Scale < 9. Overall rate of complications was 40.2 % that did not differ between the facilities. The mean HLOS at the NEMC + TCH and the TUH were 20.1 ± 25.1 and 10.5 ± 11.2 days (p < 0.001), respectively. Overall mortality was 20.7 % (n = 53). Mortality was 25.4 and 14.9 % for the NEMC + TCH and the TUH, respectively (p = 0.04). Logistic regression analysis resulted in comparable mortality at the regional trauma facilities (adj. OR 1.38; 95 % CI 0.66-2.92; p value 0.39). CONCLUSIONS: The annual incidence of injuries with ISS > 15 was 256 cases with overall mortality at 20.7 % in Estonia. We observed comparable adjusted outcomes at the major regional trauma facilities. This study contains benchmarking data on severely injured patients in Estonia providing potential for future trauma care evaluation and regional outcome comparisons.
