title: Does unit designation matter? A dedicated trauma intensive care unit is associated with lower postinjury complication rates and death after major complication.
abstract: BACKGROUND
  Recent data suggest that specialty intensive care units (ICUs) have outcomes better than those of mixed ICUs. The cause for this apparent discrepancy has not been well established. We hypothesized that trauma patients admitted to a dedicated trauma ICU (TICU) would have a lower complication rate as well as death after complication (failure to rescue [FTR]).
  
  
  METHODS
  This was a retrospective review of the ICUs of two Level I trauma centers covered by one group of surgical intensivists. One center has a dedicated TICU, while the other has a mixed ICU. Demographic and clinical characteristics were stratified into TICU and ICU groups. The primary outcomes were postinjury complications and FTR. Multivariate regression was used to derive factors associated with complications and FTR.
  
  
  RESULTS
  During the 5-year study period, 3,833 patients were analyzed. TICU patients were older (57.8 vs. 47.0 years, p < 0.0001), had higher Charlson score (2 vs. 1, p = 0.001), had more severe head injuries (Head Abbreviated Injury Scale [AIS] score ≥ 3, 50.0% vs. 37.5%, p < 0.0001), and had greater injury burden (Injury Severity Score [ISS] > 16, 49.6% vs. 38.6%, p < 0.0001) than those admitted to the mixed ICU. Need for immediate operative intervention was similar (18.0% vs. 17.6%, p = 0.788). Overall complications were significantly higher in trauma patients admitted to the mixed ICU (27.5% vs. 17.0%, p < 0.0001), as well as FTR (3.7% vs. 1.8%, p < 0.0001). Trauma patients admitted to a dedicated TICU had significantly lower chance of developing a postinjury complication (adjusted odds ratio [AOR], 0.5; p < 0.0001), FTR (AOR, 0.3; p < 0.0001), and overall mortality (AOR, 0.4; p < 0.0001).
  
  
  CONCLUSIONS
  Admission of critically ill trauma patients to a TICU staffed by a surgical intensivist is associated with a lower complication rate and FTR. Factors such as trauma nursing experience, education, and unit management structure should be further explored to elucidate the observed improved outcomes.
