Abstract

To provide more detailed data on the injury severity of persons involved in a traffic accident, Switzerland has implemented various measures. The key component was the establishment of AIS coded injury severity data. Linking the national hospital statistics to the national traffic accident statistics allowed identifying persons that were injured in a police recorded traffic accident. Using information on the diagnosis given in the hospital statistics (ICD code) the corresponding AIS code was derived. An ICD-to-AIS translator was developed, mapping the medical information to corresponding AIS codes. Since not all ICD codes correspond to a unique AIS code the translator made use of additional medical information in order to map as many cases as possible. Applying the translator to the data sets of 2011 and 2012, a MAIS could be derived for approximately 95% of all cases. Using the newly implemented procedures, it is now possible to report the share of MAIS3+ injuries sustained on Swiss roads.
