title: [Interhospital transfer of severely injured patients in Germany. Evaluation of the DGU trauma register].
abstract: BACKGROUND
  The TraumaNetzwerk(D) DGU was founded 3 years ago and since then the majority of trauma centers have been registered and organized into regional trauma network services (TNW). Within these networks assessment criteria for transferring patients to higher level hospitals are defined. The purpose of this study was to evaluate the incidence, causes, implications and quality of care for patients with major trauma who were transferred for definitive treatment before implementation of the TraumaNetzwerk(D) DGU in Germany.
  
  
  METHODS
  The data of 19,035 patients listed in the German Trauma Register of the German Society for Trauma Surgery (DGU, 2002-2007) were analyzed. Patients with an injury severity score (ISS) >9 and a blood pressure documented on admission were included into the study. Data were allocated according to patients where therapy was performed completely in the primary hospital of admission (group I; n=16,033; 84.2%) and patients transferred after primary care from one hospital to another centre for definitive care (group II; n=3,002; 15.8%). Comparative parameters were the pattern and severity of injury, physiological state on admission and clinical outcome.
  
  
  RESULTS
  Mean ISS and percentage of patients with an ISS ≥25 did not differ significantly between groups. Of the patients who were transferred to a higher level trauma centre (group II) 20.7% needed catecholamines on admission, 10.1% were in shock (blood pressure <90 mmHg) and 2.5% of the patients underwent resuscitation in the emergency department. Patients of group II had a considerably longer hospital stay (31.2±35.5 days) than patients of group I (24.8±27.1 days). Furthermore, treatment costs were significantly higher for group II (I: EUR 23,870; II: EUR 26,054).
  
  
  CONCLUSIONS
  A relevant percentage of patients transferred from one hospital to another were hemodynamically and clinically unstable. To what extent the quality of patient transfer and therefore major trauma care is improved by the implementation of regional trauma networks in Germany remains to be seen over the next years.
