AbstractTraumatic brain injury (TBI) is a major cause of morbidity and mortality in Western countries. Effective management planning for these patients requires knowledge of TBI epidemiology. The purpose of this study was to describe and analyze the development of TBI mortality in the Nordic countries during the period 1987-2001. Data on TBI deaths were retrieved from the national official statistical agencies according to specified diagnostic codes. We also collected data on the number of operations for acute TBI in the year 2000 from all Nordic hospitals admitting trauma patients. Finland had about twice as high a TBI mortality rate as the other countries. Similarly, the Finnish incidence of acute TBI operations was nearly twice that of the other countries. The median TBI death rate for Finland was 21.2 per 100,000 per year, and for Denmark, Norway, and Sweden 11.5, 10.4, and 9.5, respectively. There were more male than female deaths in all countries. The mortality rate from extracranial injuries was relatively equal between the countries. We observed a sizeable reduction in TBI mortality rates for all countries, except in Finland. Younger age groups had the most pronounced decrease in TBI mortality rates. The oldest age group had the least favorable development of TBI mortality rates, and the mean age of TBI casualties increased substantially during the study period. This study demonstrates considerable differences in and between the Nordic countries regarding TBI mortality. Preventive measures and implementation of regional guidelines are needed to assure a positive development in the future.
