BACKGROUND: @entity1 who sustain severe @entity130 , i.e., those with an Injury Severity Score (ISS) of 16 or above, go on to suffer major physical, emotional, and socio-economic consequences. It is important to know the incidence of severe @entity130 so that these @entity1 can be cared for optimally. METHODS: Data from the year 2012 on severely injured @entity1 with an ISS of 16 or above were obtained from the @entity130 registry of the German Society for @entity130 Surgery (DGU) and analyzed. Further information was obtained from the database of the DGU @entity130 network. The annual incidence of severe @entity130 was estimated from these data in three different ways. RESULTS: An extrapolation of hospital-based data to the German population yielded a figure of 16 742 severely injured @entity1 per year. A populationbased estimate from the German federal state of Bavaria yielded a figure of 16 514/year, while an area-based extrapolation using data from 17 established networks yielded a figure of 16 554/year. We added 10% to each of these figures as a correction for assumed underreporting. We conclude that the number of @entity1 who sustained a severe @entity130 in Germany in 2012 lay between 18 209 (95% confidence interval [CI]: 17 751-18 646) and 18 416 (95% CI: 18 156-18 695). This corresponds to an incidence of 0.02% per year. CONCLUSION: Data from a prospectively maintained nationwide @entity130 registry were used for the first time to calculate the annual incidence of severe @entity130 in Germany: the expected number of severely injured @entity1 per year is 18 200-18 400. Previous extrapolations yielded values in the range of 32 500-35 300. A high variability of documentation practices among supraregional @entity130 centers may have distorted the estimate, along with other factors. The figures were not normalized for age or sex.
