title: Traumatic brain injury in Poland from 2009-2012: A national study on incidence.
abstract: BACKGROUND
  Traumatic brain injury (TBI) remains one of the leading causes of mortality and morbidity worldwide. The purpose of this study was to provide data on epidemiology of TBI in Poland during 2009-2012.
  
  
  METHODS
  The national data on hospitalizations with TBI as a primary diagnosis was obtained from the National Health Fund of Poland. The sub-set of two diagnosis-related groups (DRG) was used for analysis. The incidence and mortality were calculated with the emphasis on diagnosis. The external causes of injuries were investigated based on the representative sample.
  
  
  RESULTS
  Within the study period there were 194,553 hospitalizations due to the TBI in two DRGs. The overall incidence was 126.52/10(5)/year (95% CI = 125.96-127.09). The most common diagnosis was concussion, with an incidence of 81.66/10(5)/year, and the most prevalent structural injury was subdural haematoma (15.27/10(5)/year). The predominant external causes were traffic accidents (40.52%) followed by falls (32.77%).
  
  
  CONCLUSIONS
  The incidence of TBIs in Poland compared with other countries in Europe is relatively low. The incidence of concussions mirrored current treatment guidelines rather than real epidemiology.
