Comparative Study
Ventilator-associated pneumonia is more common and of less consequence in trauma patients compared with other critically ill patients.
Ventilator-associated pneumonia (VAP) incidence is used as a quality measure. We hypothesized that patient and provider factors accounted for the higher incidence of VAP in trauma patients compared with other critically ill patients. ⋯ The incidence of VAP is greatest among trauma patients at our institution. The increased use of bronchoalveolar lavage, the earlier onset of VAP, and the higher incidence of gram-negative pneumonias suggest that both patient and provider factors may influence this phenomenon. VAP was associated with increased mortality in the nontrauma group only. These factors should be considered before VAP is applied as a quality indicator.

Comparative Study
Red blood cells accelerate the onset of clot formation in polytrauma and hemorrhagic shock.
Hemorrhage and coagulopathy are major contributors to death after trauma. The contribution of red blood cells (RBCs) in correcting coagulopathy is poorly understood. Current methods of measuring coagulopathy may fail to accurately characterize in vivo clotting. We aimed to determine the effect of RBCs on clotting parameters by comparing resuscitation regimens containing RBCs and plasma with those containing plasma alone. ⋯ Whole blood assays reveal that RBCs accelerate the onset of clot formation. Coagulation assays using spun plasma underestimate the effect of RBCs on clotting and do not completely characterize clot formation.

Shock index (SI) is recognized to be a more reliable early indicator of hemorrhage than traditional vital signs. Acute traumatic brain injury (TBI) can be associated with autonomic uncoupling and may therefore alter the reliability of SI in patients with combined TBI and peripheral hemorrhage. The aim of this study was to evaluate the performance of SI when acute TBI of mild and moderate severity were associated with progressive simple hemorrhage. ⋯ SI significantly underestimated underlying hemorrhage in the presence of acute TBI of moderate severity where attenuation of the biphasic heart rate and blood pressure response was also most pronounced.

Critical care-trained trauma surgeons are the ideal care provider for severely injured patients. This "captain of the ship" (COS) assumes complete responsibility of the patient, from initial resuscitation to eventual discharge. Unlike American College of Surgeons-verified Level I centers, many nonacademic, community hospital trauma centers use a more fragmented approach, with care in the intensive care unit (ICU) delegated to a committee of multiple specialists. We hypothesized that dedicated trauma intensivists as COS in a community hospital could improve ICU outcome. ⋯ A trauma intensivist-driven model can be successfully adopted in a nonacademic community trauma program, without the need for a residency program. A decentralized ICU care model produces inefficiencies, diminishes the role of the trauma service, and decreases the overall throughput of trauma patients.
