Fatal injuries in rural and urban areas in northern Finland: a 5-year retrospective study

Finland has the fourth highest injury mortality rate in the European Union. To better understand the causes of the high injury rate, and prevent these fatal injuries, studies are needed. Therefore, we set out to complete an analysis of the epidemiology of fatal trauma, and any contributory role for alcohol, long suspected to promote fatal injuries. As a study area, we chose the four northernmost counties of Finland; their mix of remote rural areas and urban centres allowed us to correlate mortality rates with 'rurality'.

The Causes of Death Register was consulted to identify deaths from external causes over a 5-year time period. Data were retrieved from death certificates, autopsy reports and medical records. The municipalities studied were classified as either rural or urban.

Of 2915 deaths categorized as occurring from external causes during our study period, 1959 were eligible for inclusion in our study. The annual crude mortality rate was 54 per 100,000 inhabitants; this rate was higher in rural vs. urban municipalities (65 vs. 45 per 100,000 inhabitants/year). Additionally, a greater number of pre-hospital deaths from accidental high-energy trauma occurred in rural areas (78 vs. 69%). 42% of all pre-hospital deaths occurred under the influence of alcohol.

The crude mortality rate for fatal injuries was high overall as compared to other studies, and elevated in rural areas, where pre-hospital deaths were more common. Almost half of pre-hospital deaths occurred under the influence of alcohol.
