This report provides a review of Swedish experiences concerning the national road traffic accident information system STRADA (Swedish Traffic Accident Data Acquisition). STRADA contains information on accidents occurring in the Swedish road transport system as reported by the police, and medical data on persons injured as reported by the hospitals. By combining data from two sources, the STRADA system can provide more comprehensive information on both the circumstances and the consequences of road traffic accidents. The aim was to provide a review of accident and injury data in STRADA, including methods for collecting, sharing and analyzing the data. The primary focus is on the injury data provided by the hospitals and how these can be used in conjunction with police data. The main results provided in this report are descriptions of how the STRADA database is structured and what data are available, how the police and hospitals collect data, and how the data are made available to various stakeholders. The report describes the organizations involved in maintaining and developing the STRADA system and a number of examples of how hospital data has been used in various projects are also provided. Information about STRADA was compiled mainly from material provided by the responsible authority – The Swedish Transport Agency. In addition, a literature review was performed in order to identify examples of how hospital data has been used in different projects. The report was commissioned by the Belgian Road Safety Institute (BRSI). (Author/publisher)
