The effect of blood component ratios on the survival of patients with traumatic brain injury (TBI) has not been studied. ⋯ High platelet ratio was associated with improved survival in TBI+ patients while a high plasma ratio was associated with improved survival in TBI- patients. Prospective studies of blood product ratios should include TBI in the analysis for determination of optimal use of ratios on outcome in injured patients.

Elements of volume resuscitation from hemorrhagic shock, such as amount of blood product and crystalloid administration, have been shown to be associated with multiple organ dysfunction (MOD). However, it is unknown whether these are causative factors or merely markers of an underlying requirement for large-volume resuscitation. We sought to further delineate the relevance of the major individual components of early volume resuscitation to onset of MOD after severe blunt traumatic injury. ⋯ When controlling for all major components of acute volume resuscitation, massive-transfusion volumes of PRBC's within the first 12 hours of resuscitation are modestly associated with MOD, whereas FFP and large volume crystalloid administration are not independently associated with MOD. Previous reported associations of blood products and large-volume crystalloid with MOD may be reflecting overall resuscitation requirements and burden of injury rather than independent causation.

Trauma systems have improved short-term survival of the severely injured but knowledge on long-term outcome is limited. This study aimed to assess outcome 6 years to 9 years after moderate to severe injury in terms of survival, Health-Related Quality of Life (HRQOL) and employment status. ⋯ Six years to nine years after traumatic injury, 78% of the patients were alive. HRQOL was significantly lower for injured patients than a matched control group. Twenty percentage of the patients retired early.

Infection is a major complication associated with combat-related injuries. One strategy to decrease infections is immediate delivery of antimicrobials at or near the point-of-injury by the casualty or the first medical responder. The 75th Ranger Regiment systematically collects data on prehospital battlefield care, including antimicrobial administration. We review infectious complications and colonization rates associated with delivery of point-of-injury antimicrobial therapy. ⋯ Although limited by population size, a significant difference in infection rates and multidrug-resistant pathogen colonization was not seen in those casualties who received single-dose broad-spectrum antimicrobials at the point-of-injury, confirming neither benefit nor harm. Overall adherence with initiating point-of-injury antimicrobials was low.

Several studies in the literature have examined the volume-outcome relationship for trauma, but the findings have been mixed, and the associated impact of the trauma center level has not been examined to date. The purposes of this study are to (1) determine whether there is a significant relationship between the annual volume of trauma inpatients treated in a trauma center (with "patients" defined in multiple ways) and short-term mortality of those patients, and (2) examine the impact on the volume-mortality relationship of being a Level I versus Level II trauma center. ⋯ When considering the trauma system as a whole, higher total annual trauma center volume (2,000 or higher) and higher volume of patients with ISS ≥16 (240 and higher) are significant predictors of lower in-hospital mortality. Although the American College of Surgeons-recommended 1,200 total volume is not a significant predictor, hospitals in New York with ISS ≥16 volumes in excess of 240 also have total volumes in excess of 2,000. However, when considering individual trauma centers, high volume centers do not consistently perform better than low volume centers. Thus, despite the association between volume and mortality, we believe that the most accurate way to assess trauma center performance is through the use of an accurate, complete, comprehensive database for computing center-specific risk-adjusted mortality rates, rather than volume per se.
