Background: The organisation of trauma care in Scandinavia has several similarities, including trauma registries, but so far there are limited amount of research on efficiency and outcome. Data and results from trauma outcome studies like the US MTOS are not fully applicable to the Scandinavian trauma population. Aims: To reveal the feasibility of using data from existing trauma registries of major hospitals in Scandinavia, for a minimal common dataset, in a joint, prospective Scandinavian MTOS. Material and Methods: We collected data points, data point definitions, and inclusion/exclusion criteria, from the major trauma registries of the Swedish trauma registry standard, three university hospitals in Denmark, one university hospital in Finland, and the Norwegian National Trauma Registry. The collected material was compared to reveal common data points, inclusion criteria, and the compatibility of data point definitions. Results: The median number of data points was 147 (range 71–257; interquartile range = 90–205). Most registries lacked precise data definition catalogues. Only 16 data points could be considered as common, of which just a few were core trauma data. Four data points had the same data category options but were not considered having the same data point definitions. The inclusion criteria were not uniform. Conclusions: Trauma registries in Scandinavia have few common core data and data point definitions. There were data points for calculating the Trauma and Injury Severity Score (TRISS) but the inclusion criteria varied too much to ensure a valid comparison. A consensus process for a joint trauma core data set will be initiated by the Scandinavian Networking Group for Trauma and Emergency Management (SCANTEM) to increase research on trauma efficiency and outcome.
