title: Improved outcome after trauma care in university-level intensive care units.
abstract: BACKGROUND
  Centralized trauma care has been shown to be associated with improved patient outcome. We compared the outcomes of trauma patients in relation to the size of the intensive care unit (ICU) using a large Finnish database.
  
  
  METHODS
  A national prospectively collected ICU data registry was used for analysis. All adult trauma admissions excluding isolated head trauma and burns registered from July 1999 to December 2006 were analyzed. Data from 22 ICUs were available. The non-university-affiliated units were categorized according to the number of beds and referral population as small, mid size and large. Acute physiology and chronic health evaluation (APACHE II)- and sequential organ failure assessment (SOFA)-adjusted mortalities were compared between the units.
  
  
  RESULTS
  There were 2067 trauma admissions that fulfilled the inclusion criteria; 38% were treated in the university hospitals, 26% in large non-teaching ICUs, 20% in mid size ICUs and 15% in small ICUs. The crude hospital mortality was 5.6%, being 4.7% in university ICU and 6.6% in mid size ICU. In two subgroup analyses of severely ill trauma patients with APACHE II points >25 or SOFA score >8 points, respectively, hospital mortality was significantly lower in university ICUs.
  
  
  CONCLUSIONS
  University-level hospitals were associated with better outcomes with critically ill trauma patients. These results can be used in planning future organization of trauma patient care in Finland.
